Job Description

Vercel is the agentic infrastructure company, freeing people and agents to ship what’s next. The company is scaling its products for both agents and people to ship and run software, built in the open and trusted by OpenAI, PayPal, Ramp, Supreme, and millions of developers worldwide.

We are looking for a Software Engineer, Trust & Safety, to design, build, and operate the large-scale, real-time distributed systems that stop abuse and fraud on the platform, including fraud committed through AI agents, fraud that abuses deployments and compute resources, and payment fraud on token-based usage. You will write the services, detection systems, and large language model (LLM) tooling that disrupt abuse at internet scale. This is a hybrid role based in San Francisco or New York City, with three days a week in the office.

What you’ll do:

  • Design and build production services that detect and disrupt fraud committed through AI agents, fraud that abuses deployments and compute resources, and payment fraud on token-based usage
  • Build detection systems that find abuse patterns across large datasets
  • Ship LLM-driven systems for abuse detection, classification, and prevention, and build the datasets and evaluation pipelines that measure them
  • Build and maintain internal tools for trust and safety workflows
  • Analyze threat actor behavior to inform detection logic, and work with security, product, and infrastructure teams to move prototypes into stable production

What you need:

  • 5+ years of software engineering experience building large-scale, real-time distributed systems
  • Wrote and shipped production code in JavaScript/TypeScript and Python, owning systems end to end
  • Hands-on LLM experience, including prompt engineering, evaluation, and fine-tuning
  • Operated production services on AWS

Bonus if you:

  • Shipped an AI-based trust and safety system to production
  • Worked in abuse prevention, trust and safety, or security engineering
  • Built or hosted a project on Vercel

Benefits and Compensation:

  • Competitive compensation package, including equity
  • Inclusive Healthcare Package
  • Learn and Grow – mentorship and events that help you build your network and skills
  • Flexible Time Off
  • Gear you need to do your role, and a WFH budget for your space

The San Francisco, CA base pay range for this role is $208,000 – $312,000.
