About the role
- It is both deployed into customer environments and hosted by us.
- It is also the central platform for every internal agent at Mercor, scaling to several thousand agent runs per day, and still growing.
- You will work across the full stack: enterprise-grade security and the routing plane, isolated execution, and the intelligence plane that turns production runs into improvements.
Responsibilities
- Design the interfaces other engineers build agents against, and keep the paved path the easiest one to follow.
- Build the event-driven backbone so that ingestion stays idempotent when services scale horizontally.
- Own the deployment model itself, from our hosted offering to customer VPCs and multi-cloud, so a new deployment needs no bespoke build.
- Keep tenants isolated by construction, so one run cannot reach or spend beyond its own quota.
- Own latency, throughput, and cost per run as volume grows, along with the production debugging that comes with them.
- Set the direction for the parts of the platform you own, not just the implementation.
- Partner closely with Applied AI engineers on the hardest problems coming out of deployments. They own the customer relationship, you own the platform.
- Design, build, and operate the services the platform is made of: authn and authz, credential brokering, routing, sandboxing, and orchestration.
Requirements
- Bachelor's Degree in Computer Science or a related technical degree such as Electrical Engineering, Physics, Mathematics, Computer Engineering, Information Systems or Statistics
- 5+ years of experience building high scale, complex software systems
- You have built and operated a platform other engineers depended on, and owned the architectural calls on it rather than only the implementation.
- Demonstrated ability to work independently on ambiguous, loosely specified problems.
Benefits
- Up to $15k relocation bonus
- $10K housing bonus (if you live within 0.5 miles of our office)
- $1.5K monthly stipend for meals
- Generous equity grant vested over 4 years
- $200 monthly laundry reimbursement
- $200 monthly personal wellness reimbursement
- Health, Dental, Vision insurance
