About the company

Our client is a fast-growing software company.

The role

Raydar is recruiting for this role on behalf of our client. Design, build and run backend modules for a software platform, taking responsibility from early scoping through release and production support. Work alongside engineering and customer-facing colleagues to turn bespoke solutions into reusable products, including automated AI-driven workflows.

What you'll do

  • Design and build backend platform modules that support business operations at scale.
  • Take charge of a product area across its full lifecycle, with attention to reliability, security and low error rates.
  • Collaborate with deployed engineers, customer success and technical leadership to generalize one-off solutions into reusable products.
  • Develop and operate AI agents in production, adding testing, safeguards, monitoring and feedback mechanisms.
  • Lead infrastructure initiatives from planning to rollout, such as internal tooling that lets non-technical colleagues set up custom modules.
  • Shape data structures, processing pipelines and connections to third-party systems, including those that lack APIs.
  • Handle on-call rotation and root-cause investigations for the systems you build.

What we're looking for

  • At least 4 years of backend or systems engineering experience, with 6 to 7 years ideal; full-stack is fine if backend-heavy.
  • Experience running reliable, scalable production systems.
  • A degree from a top engineering school or engineering experience at a high-caliber technology company.
  • A history of taking a service or module from concept to stable production use on your own.
  • Hands-on experience delivering LLM-based or agent-based features to production users, as an applied engineer rather than a model researcher.
  • Daily use of AI coding tools.
  • Comfort working independently in a fast-paced, in-person team.
  • Ability to work on-site 5 days a week.

Bonus points

  • Experience at a fast-growing startup.
  • Experience with Python or TypeScript.
  • Top engineering school background.

Benefits

  • Health, dental and vision coverage

Location and work model

  • San Francisco, California, United States
  • On-site, 5 days per week
  • Full-time

Compensation, as the posting describes it

  • Equity
  • Flexible time off
