About the roleWe're looking for a Trust & Safety Program Engineer to own and scale our internal detection and investigation tooling. You will build the pipelines, queues, and reviewer workflows that transform raw signals into actionable decisions. This is a high-ownership role: you'll take production responsibility for critical internal systems, partner deeply with T&S operations, and (where it makes sense) apply modern AI approaches to reduce manual work and speed up response.
If you enjoy building real systems used daily, and you care about reliability, measurement, and practical impact, you'll fit well here.
In this role, you will:- Own and maintain internal detection tools and signal pipelines (starting with the Orb Risk Program).
- Build triage and investigation workflows: prioritization, deduplication, SLA tracking, evidence/context surfacing.
- Ship one-click actions and audit logging for common outcomes and escalations.
- Build documentation: signal catalog, runbooks, incident response processes for pipeline failures.
- Partner with operational users to iterate quickly and measurably reduce manual work.
- Where appropriate, design and deploy agentic/LLM workflows with evaluation and monitoring.
You might thrive in this role if you have:- Bachelor's degree in Computer Science, Engineering, Mathematics, or a related technical field, or equivalent practical experience
- 8+ years of experience across systems, or program engineering, with ownership of production systems or operational programs
- Strong software engineering fundamentals: system design, testing, observability, and production ownership.
- Proficient in Python and TypeScript; strong SQL for analysis and validation.
- Experience building internal tools or workflow systems (queues, case management, review UIs).
- Comfortable operating in ambiguous problem spaces with high accountability.
- Bonus: T&S/fraud/risk/security domain experience and/or agentic/LLM systems shipped to production.
