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. About the Role We're hiring a hands-on Engineering Manager to build and lead Replit's Anti-Abuse team from the ground up. This is a foundational 0-to-1 role: you'll define the anti-abuse roadmap, hire a small team of engineers and data analysts, and ship the systems that protect Replit's platform, users, and economics from adversarial actors. You'll partner across Support, Legal, Security, Infrastructure, and the Money and Growth teams 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, and increasingly, abuse driven by AI agents themselves. The team you build will define how Replit defends against all of it. What You'll Do Build the anti-abuse roadmap from scratch : Define the threat model, prioritize across abuse vectors (phishing/scam hosting, cryptomining, token farming, payment fraud, AI agent exploitation), and translate it into a shipping plan with clear sequencing and tradeoffs. Design progressive verification and identity infrastructure : Build the "ladder of trust" that gates increasing platform capabilities (referrals, additional credits, access to powerful agent features, Missions) behind escalating verification. This includes a humanity/identity layer that's distinct from user accounts, integrations with KYC-grade verification providers, and the policy engine that decides what level of trust unlocks what behavior. This infrastructure is core not just to promo integrity but to how Replit safely expands agent capabilities over time. Ship as a hands-on EM : Stay in the code. Use the latest AI coding tools (including Rep

Candidates that do well here will certainly go on to build their own companies in the future! This is a high visibility role reporting to Execution Model: High-Agency Founding Teams Structure: We operate as a collective of in-house technical founders —not just specialized engineers. Initiatives are run by lean, autonomous squads built for velocity and maximum technical leverage. This model is centered around an Engineer DRI (Directly Responsible Individual) who maintains total ownership over the initiative's technical, product, and launch success, supported by fractional PM and Design resources. Cadence: We enforce rapid iteration and rapid market validation via 3-week sprints per initiative. This cadence forces fast deployment, immediate user feedback, and tight alignment with the internal betting table process, mirroring the intensity and speed of a lean startup. Required skills and

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. About the Team Product Platform builds and owns the shared foundations the rest of Replit is built on, spanning the full stack so every other team can ship features safely and quickly: backend infrastructure, connectors, product primitives, and the frontend platform. Our work is high-leverage and horizontal: when our foundations are solid every other team moves faster, and the role gives you exposure across the whole of engineering. We are a small, collaborative team that values curiosity and clear thinking over pedigree, and we work in the open by bringing each other the problem rather than just the request. We care more about how you reason and build than the route you took to get here. About The Role As a Product Engineer , you can focus on frontend, backend, or full-stack work building the shared systems other teams depend on. The work is guided by a few simple questions: Are our shared systems fast, reliable, and cost-efficient as traffic grows? Are we making product development safe by default, consistent, and faster? Can a builder connect a third-party service once and have it work safely across every app they build? Are user-facing surfaces consistent and fast, with shared primitives teams can build on? Is our codebase easy to navigate, change, and extend, including for AI coding agents? What you’ll do Design reusable primitives and interfaces with clear contracts and documentation that other teams adopt Work directly with product teams to turn their friction into platform improvements Profile and instrument shared systems, then ship the improvements that move latency, cost, and reliability Harden systems against failure and abuse, and make safe defaults the path of least resistance Set technical direction in a
