Distributed SystemsAuditingAdaptability
About the role
- Our vast talent network trains frontier AI models in the same way teachers teach students: by sharing knowledge, experience, and context that can't be captured in code alone.
- Today, more than 30,000 experts in our network collectively earn over $3 million a day.
- Mercor is creating a new category of work where expertise powers AI advancement.
Responsibilities
- Talk directly with ops teams to understand business requirements, then translate them into large-scale distributed systems that are designed with security in mind from the start
- Build and scale the infrastructure that manages expert identity and access across thousands of Slack workspaces, enterprise groups, and HR systems - systems that already operate at a scale most engineers never encounter
- Own your scope end to end: define the approach, build it, and iterate on it as requirements evolve
- Design for the security implications of what you're building - not auditing after the fact, but thinking through how gaps in system design compound at scale
- We partner with leading AI labs and enterprises to provide the human intelligence essential to AI development.
Requirements
- Large-scale distributed systems experience - this is the most identifiable signal on a resume and a strong filter
- The problems are novel, the scale is real, and the team has a strong track record of bringing in sharp product engineers - regardless of prior security background - and watching them thrive.
Benefits
- Generous equity, vested over 4 years
- Up to $15K relocation bonus
- $10K housing bonus (if you live within 0.5 miles of the office)
- $1,500/month meals stipend
- $200/month laundry reimbursement
- $200/month personal wellness reimbursement
- Health, Dental, and Vision insurance
Company info
- by sharing knowledge, experience, and context that can't be captured in code alone.
- Achieving this requires an ambitious, fast-paced and deeply committed team.
- You'll work alongside researchers, operators, and AI companies at the forefront of shaping the systems that are redefining society.
- Mercor is a profitable Series C company valued at $10 billion.
- We work in-person five days a week in our San Francisco, NYC, or London offices.
- Why This Role
- Mercor's identity infrastructure is unlike anything else in the Valley.
- Our enterprise Slack alone spans thousands of workspaces and tens of thousands of channels - with over 63,000 users today, the vast majority of whom are contractors and experts, not employees.
- That number is on track to hit 100,000.
- Managing access, identity, and permissions at that scale, across a global expert network spanning every client project we run, is one of the hardest distributed systems problems we have.
- This team is led by Mercor's first engineer.
