Product Engineer, New Products

Replit is the agentic software creation platform that enables anyone to build applications using natural language. With millions of users worldwide, Replit is democratizing software development by removing traditional barriers to application creation.<h2> About the Role</h2>We're redefining how software is built and who gets to build it. Our mission is to achieve Autonomy for All: making programming accessible, collaborative, and powered by AI. Realizing that vision requires a platform that legitimate users can trust and adversarial actors cannot exploit. We're hiring a Data Scientist to help build Replit's Trust &amp; Safety and Anti-Abuse program from the ground up. You'll turn noisy behavioral, identity, payment, infrastructure, and content signals into the measurement systems, detections, and decisions that protect Replit's users, platform, and economics. You'll work closely with Engineering, Support, Legal, Security, Infrastructure, Money, and Growth to make abuse economically unviable while keeping friction low for legitimate users. Replit sits at the frontier of AI-native abuse. Our platform is a target for phishing and scam hosting, cryptomining, LLM token farming, card and coupon fraud, referral abuse, and increasingly, abuse driven by AI agents themselves. You'll help define how we identify, measure, and respond to these threats without compromising the experience of good users.<h2> Who You Are</h2>You're a data scientist who moves fast, goes deep, and thinks adversarially. You can spin up an analysis in hours that would take others days, not by cutting corners, but because you've built the intuition and technical toolkit to get to the right answer quickly. You dig past the top-line abuse rate to understand selection effects, missing labels, policy changes, attacker adaptation, and the false positives hidden inside an aggregate metric.You understand that Trust &amp; Safety data is imperfect and outcomes are high stakes. Ground truth is delayed, biased, and often incomplete; attackers react to defenses; and an apparently effective rule can quietly harm legitimate users. You pressure-test your own work, quantify uncertainty, and distinguish correlation from evidence strong enough to justify enforcement.You use AI agents and tools aggressively to multiply your output: writing code, exploring data, generating hypotheses, and prototyping investigations. But you treat every AI-assisted output as a draft, not a deliverable. You know what good analysis looks like and won't ship anything that doesn't meet that bar.<h2> You Will</h2><ul><li>Own the analytical foundation for Trust &amp; Safety, including abuse prevalence, fraud loss, false-positive and false-negative rates, time to detect, time to mitigate, appeal and reversal rates, and verification step-up conversion.</li><li>Build reliable datasets and dbt models that connect product events, account and identity signals, payment activity, infrastructure usage, content classifications, enforcement actions, appeals, and support outcomes.</li><li>Develop and evaluate risk models, rules, and anomaly-detection systems for threats such as phishing, scam hosting, cryptomining, token farming, payment fraud, promotional abuse, and AI-agent exploitation.</li><li>Design rigorous offline evaluations, shadow-mode tests, holdouts, and controlled experiments to measure detection quality and the user impact of new policies, enforcement actions, and progressive verification.</li><li>Define thresholds and decision frameworks that balance abuse reduction, economic loss, customer friction, and false positives across free, paid, and enterprise users.</li><li>Investigate emerging abuse patterns, quantify their impact, identify coordinated behavior, and turn ambiguous signals into clear recommendations for product and engineering teams.</li><li>Develop predictive models that estimate account, device, transaction, workspace, or deployment risk and embed those signals into detection, review, and escalation workflows.</li><li>Partner with Support and Legal to improve case review, appeals, reason-code quality, and feedback loops so human decisions become useful model and policy signals.</li><li>Build monitoring that detects model drift, attacker adaptation, data-quality failures, and unexpected harm to legitimate users.</li><li>Communicate findings clearly to technical and non-technical partners, including the tradeoffs, uncertainty, and evidence behind high-impact decisions.</li></ul><h2> Examples of What You Could Do</h2><ul><li>Build a measurement framework for Replit's abuse surface, reconcile incomplete labels across automated detections, human review, appeals, chargebacks, and support cases, and establish a trustworthy baseline for the first time.</li><li>Design and evaluate a risk-scoring model for suspicious account clusters using identity, device, payment, graph, and product-behavior signals, then define thresholds that materially reduce fraud while protecting legitimate users.</li><li>Analyze a phishing detection rule that appears highly precise, uncover that it disproportionately bans paying users with legitimate brand references, and redesign its evaluation and review path to reduce false positives.</li><li>Measure a progressive verification "ladder of trust," determining when to step users up to additional verification and quantifying the tradeoff between abuse prevented and legitimate-user conversion lost.</li><li>Detect coordinated token-farming or promotional-abuse networks by combining account-linkage graphs, referral behavior, payment patterns, and infrastructure usage, then partner with Engineering to operationalize the findings.</li><li>Evaluate a new enforcement policy in shadow mode, estimate its counterfactual impact, and recommend whether to launch, revise, or reject it before any users are affected.</li></ul><h2> Required Skills and Experience</h2><ul><li>5+ years of experience in data science, product analytics, fraud, risk, trust and safety, or a related field.</li><li>Strong SQL and Python skills, with experience working with large behavioral datasets and building reliable data models or pipelines.</li><li>Experience developing and evaluating predictive models, experiments, or decision systems, with sound judgment around uncertainty and tradeoffs.</li><li>Ability to turn ambiguous data into clear recommendations and communicate them effectively across technical and non-technical teams.</li><li>Comfort working with imperfect labels, biased samples, and high-impact decisions where false positives matter.</li><li>You use AI tools extensively to increase your effectiveness while maintaining a high bar for analytical quality.</li></ul><h2> Preferred Qualifications</h2><ul><li>Experience building or evaluating anti-abuse, fraud, identity, security, spam, integrity, or content-safety systems at scale.</li><li>Built, shipped, and maintained ML models in production (classification, anomaly detection, or risk scoring), including feature engineering on behavioral and transaction data, threshold selection against precision/recall economics, and post-launch monitoring</li><li>Experience with graph analysis, entity resolution, coordinated-behavior detection, reputation systems, anomaly detection, or risk scoring.</li><li>Experience measuring false positives and enforcement harm, designing human-review workflows, or using appeals and case outcomes as model feedback.</li><li>Familiarity with progressive verification, KYC, account trust, or identity providers such as Prove, Persona, Socure, or Stripe Identity.</li><li>Experience with causal inference methods such as difference-in-differences, propensity score methods, synthetic control, or uplift modeling.</li><li>Experience with a modern data stack such as dbt, BigQuery, Snowflake, Fivetran, Amplitude, Mixpanel, or Segment.</li><li>Experience at a consumer platform, developer tool, cloud provider, marketplace, fintech company, or other product with a meaningful adversarial surface.</li></ul><h2> Bonus Points</h2><ul><li>You've built AI-powered analytical tools, investigation systems, automated detections, or novel measurement approaches.</li><li>You have experience with AI-native abuse such as prompt injection, LLM token farming, model extraction, or agent-driven abuse.</li><li>You understand freemium, usage-based, or promotional pricing models and the abuse incentives they create.</li><li>You've worked directly with operational review teams and can translate analytical signals into practical playbooks, queues, and escalation paths. </li></ul>This is a full-time role that can be held from our Foster City, CA office.

Data Scientist, Trust & Safety

Replit is the agentic software creation platform that enables anyone to build applications using natural language. With millions of users worldwide, Replit is democratizing software development by removing traditional barriers to application creation. The AI Studio is the team responsible for designing, building, and operationalizing internal software platforms across every functional department of the company, including People Operations, Customer Support, Sales, Marketing, Finance, Recruiting, and Executive Operations. We treat each internal department as its own product surface, and in truth as its own startup, with its own customers, its own metrics, and its own reasons for existing. We ship custom software, built on Replit’s own platform, to solve operational problems that off-the-shelf SaaS tools cannot serve well at our scale and pace of growth. <h2>Position Summary</h2>The Member of Technical Staff (AI Builder) is a full-time builder role with substantial autonomy. You will design, architect, and ship AI-powered internal platforms that run the operations of the company across many departments at once. This is not a role for someone who wants a narrow, well-defined lane. It is a role for someone who wants to walk into an ambiguous business problem, understand it well enough to argue about it with the department lead, and then ship the software that fixes it.We are looking for people who genuinely understand the mechanics of a business: how revenue is actually made, why recruiting velocity matters, what makes support scale or break, how finance closes a month, and why each department is critical to whether the company wins or loses. You do not need to have run every function, but you need to respect why each one exists and be able to reason about it like an operator, not just an engineer.Because we treat each department as its own startup, we strongly favor people who have either run their own business or worked on a fast-scaling startup. You know what it feels like to build with incomplete information, to ship before it is comfortable, and to own an outcome rather than a ticket. The work is genuinely a ton of fun, and it is also demanding: it rewards diplomacy, creativity, technical depth, and business acumen in roughly equal measure. You will move fast, work long hours when it matters, and switch fluidly between a deep technical conversation and a conversation with a non-technical stakeholder who just needs their problem solved.<h2> Key Responsibilities</h2><h2> Internal Platform Design and Engineering</h2><ul><li>Design, architect, and ship custom AI-powered internal platforms that serve specific operational needs across Replit’s functional departments, including but not limited to People Operations, Customer Support, Sales, Recruiting, Marketing, Finance, and Executive Operations.</li><li>Translate ambiguous, often non-technical business requirements into technical specifications, system architectures, and shipped software products.</li><li>Own platform development end-to-end, including front-end interfaces, back-end services, data models, third-party integrations, and AI model orchestration.</li></ul>Applied AI and Large Language Model Engineering<ul><li>Architect multi-stage AI pipelines incorporating large language models, including prompt engineering, tool-call architecture, structured output generation, retrieval-augmented generation, and agentic workflows.</li><li>Conduct model selection across multiple frontier and open-source providers, evaluating models against cost per query, latency, output quality, reliability, and task-specific performance.</li><li>Design and implement evaluation frameworks for AI features, including test datasets, scoring rubrics, and regression tests, so that AI-driven workflows stay reliable in production.</li><li>Optimize AI systems for cost and performance, including the appropriate use of lighter-weight models for qualification passes, batching strategies for high-throughput workloads, and caching architectures.</li></ul>Business Understanding and Stakeholder Partnership<ul><li>Treat each internal department as its own startup: understand its goals, its constraints, and the metrics that define whether it is succeeding.</li><li>Partner directly with department leads to identify operational inefficiencies, scope solutions, and prioritize the work that creates the most leverage.</li><li>Conduct stakeholder interviews, lead requirements-gathering sessions, and translate qualitative feedback into iterative product improvements.</li><li>Present technical work and operational outcomes to executive leadership, including the President and senior staff, and do it in language each audience can act on.</li></ul>Third-Party System Integration<ul><li>Design and implement integrations with the third-party platforms used at Replit, including enterprise HR platforms, support ticketing systems, CRM platforms, applicant tracking systems, project management tools, and identity providers.</li><li>Evaluate third-party APIs, SDKs, and data schemas, and design integration architectures appropriate to scale, security, and maintainability requirements.</li></ul>Production Operations and Reliability<ul><li>Maintain and operate shipped platforms in production, including dependency management, security updates, observability, error handling, and performance monitoring.</li><li>Respond to production incidents and continuously iterate on shipped platforms based on user feedback and operational telemetry.</li></ul>Documentation and Knowledge Transfer<ul><li>Document architectural decisions, system designs, and operational procedures for shipped platforms.</li><li>Onboard future team members and contribute to the evolution of the AI Studio as the function scales.</li></ul><h2>Who You Are</h2><ul><li>You understand how a business actually works and can explain why each department matters to the company winning.</li><li>You have either run your own business or worked on a fast-scaling startup, and you carry the ownership instinct that comes with it.</li><li>You are comfortable with long hours and a very high pace, and you treat that as part of the fun rather than a cost.</li><li>You can engage credibly with both deeply technical people and non-technical stakeholders, often in the same afternoon.</li><li>You bring diplomacy, creativity, technical knowledge, and business acumen, and you know when each one is the tool the moment calls for.</li><li>You would rather ship something real and iterate than wait for perfect information.</li></ul><h2>Experience and Qualifications</h2><ul><li>Bachelor’s or master’s degree in Technology Management, Computer Science, Software Engineering, Information Systems, or a closely related technical or technology-business hybrid field. Equivalent foreign degrees acceptable subject to credential evaluation.
