About the job
As a Software Engineer on our Trust & Safety 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.
Responsibilities
Analyze threat actor behavior and evolving abuse patterns across large, heterogeneous datasets to inform detection logic, policy decisions, and scalable mitigations.
Research, prototype, and implement state-of-the-art LLM-driven techniques for abuse detection, classification, and prevention.
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.
Collaborate closely with security, product, and infrastructure teams to bring research ideas into stable, scalable production systems.
Qualifications
