About the role
- Mercor's products-talent matching, assessment, expert workflows-are growing faster than any single team can architect for.
- You'll define the technical direction of the systems they all depend on: core services, data models, APIs, and infrastructure patterns that must scale with a network of tens of thousands of experts and the demands of the world's leading AI labs.
- This is a hands-on technical leadership role, not a management role.
Responsibilities
- Own the architecture of Mercor's shared backend systems-core services, data models, APIs, and cross-product infrastructure.
- Define and drive the long-term technical strategy for backend architecture across the organization.
- Design systems for scale, reliability, and evolvability, and lead the highest-stakes technical decisions and design reviews.
- Identify and pay down architectural debt that slows product teams, and lead complex cross-team migrations.
- Partner with engineering and product leadership on build-vs-buy decisions, platform investments, and technical hiring.
- Deep expertise in distributed systems, service architecture, data modeling, and API design at scale.
- Strong opinions, loosely held: you drive alignment through technical judgment and clear writing, not authority.
Requirements
- 8+ years of professional backend engineering experience, including 3+ years operating at a Senior level or above.
- A track record of owning architecture across multiple teams or an entire organization-and of decisions that aged well.
- Experience leading large, complex technical migrations in production without stopping the business.
- Experience mentoring senior engineers and raising the technical bar across an organization.
Benefits
- Generous equity grant vested over 4 years
- A $20K relocation bonus (if moving to the Bay Area)
- A $10K housing bonus (if you live within 0.5 miles of our office)
- A $1.5K monthly stipend for meals
- Health insurance
