As a Senior Software Engineer on our Trust & Safety team at Vercel, you’ll build and operate systems that protect millions of developers and projects from abuse at internet scale. You’ll analyze real-world threat actor behavior, detect emerging abuse patterns across large datasets, and design production-ready mitigations to keep the platform safe without slowing developers. This role blends security engineering, data analysis, and applied LLM techniques, working closely with product, infrastructure, and security teams to turn evolving threats into scalable defenses.

If you’re based within a pre-determined commuting distance of one of our offices (SF, NY, London, or Berlin), the role includes in-office anchor days on Monday, Tuesday, and Friday. If you're located beyond that distance, the role is fully remote. Analyze threat actor behavior and evolving abuse patterns across large, heterogeneous datasets to inform detection logic, policy decisions, and scalable mitigations.

Design and develop production-ready systems that detect and disrupt abusive behavior across the Vercel platform.

Build, maintain, and fine-tune internal tools, datasets, and evaluation pipelines for trust and safety workflows.

Strong programming skills in JavaScript/TypeScript and Python.

Hands-on experience working with LLMs, including prompt engineering, evaluation, and fine-tuning.

Solid understanding of cloud infrastructure, including AWS.

Experience owning systems end-to-end, from initial research through production deployment and iteration.

Competitive compensation package, including equity.
