Job Description

Seeking 2–3 experienced full-stack engineers to lead key backend initiatives and help scale Codegen’s core systems from prototype to production. Ideal candidate would have 5+ years of software experience, strong backend engineering skills with Python, and end-to-end ownership of production systems.

About the role

You’ll own and evolve key backend systems that power the Codegen platform. This includes distributed task execution for AI-driven “solves,” developer sandbox orchestration and lifecycle management, and systems for ingesting and retrieving customer knowledge. You'll prototype new features end-to-end, then scale and harden them for production use. Working closely with a high-trust, fast-moving team across product, infrastructure, and AI, you'll ship real systems used by developers daily — from Slack workflows to production environments.


Qualifications

Minimum Qualifications:
  • 5+ years of professional software experience
  • Strong backend engineering skills with Python (or adjacent ecosystems)
  • Experience designing, building, and maintaining production systems end-to-end
  • Ability to work independently and drive large technical projects
  • Familiarity with system architecture, stateful services, and distributed compute
  • Prior experience at high-performance teams (e.g., Stripe, Palantir, Uber)

Bonus Experience:
  • Building developer bots or integrations in Slack, Discord, etc.
  • Exposure to AI/ML developer tooling (LangChain, OpenAI, Anthropic, etc.)
  • Comfortable leading cross-functional initiatives or mentoring engineers
  • Familiarity with fast-paced, early-stage product iteration cycles


Responsibilities

  • Own and evolve core backend systems, including:
    • Distributed task execution for AI-powered “solves”
    • Developer sandbox orchestration and lifecycle management
    • Customer knowledge ingestion and retrieval
  • Prototype features end-to-end, then harden them for scale and reliability
  • Collaborate with a high-trust, fast-moving team across product, infra, and AI
  • Ship real systems that developers use daily — from Slack to production
