About the role

What you'll do

  • Own systems that automate repetitive work across browser and desktop, handling concurrency, reliability, and observability at scale (millions of executions per month)
  • Collaborate with our CTO and ML research partners to bring state-of-the-art agentic workflows into production
  • Architect and build the backend systems that power our visual workflow builder – a Figma-style interface used daily by non-technical ops teams
  • Design and implement services that integrate with Sola AI models to generate workflows, gain insights, and drive adaptive execution logic

What we're looking for

  • You thrive in a fast-paced environment where you can ship fast and solve problems end-to-end
  • You’ve built and operated distributed systems at scale, with a high standard for reliability, observability, and performance
  • You’re proficient across all layers on the backend, from infra to CI/CD to DB to backend service architecture
  • You’re fluent with the latest AI coding tools and are always looking for ways to move faster
  • You’re open to working 5 days a week out of our office in NYC (we’ll cover relocation!)

You might excel if

  • You have hands-on experience operating at an early stage startup where ownership and execution in the face of ambiguity were essential
  • You’re an expert in some or all of our stack: TypeScript and Python, Kubernetes, Temporal, Postgres, DynamoDB
  • You’ve worked directly on AI systems or in ML ops at scale
  • You’re ambitious, creative, and a great communicator

Compensation & Benefits

  • Competitive salary plus meaningful equity at Series A stage. Exact compensation is based on experience and level.
  • Comprehensive medical, dental, and vision benefits, 401(k) matching, daily meals together in the office, flexible PTO (4 weeks per year), and relocation support for candidates not already based in NYC.
