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 and run backend-heavy services for a software platform while also delivering the front-end features that make them usable. Partner closely with company leadership and external users, holding wide ownership of technical and product choices from the outset.
What you'll do
- Build and maintain backend services that support a data-driven software platform.
- Design data models for datasets, test runs, traces, versioned content and user-defined quality criteria.
- Own connections to third-party systems across their lifecycle, from authentication and webhooks to syncing, error handling, monitoring and production support.
- Carry features from initial design through release and ongoing iteration based on feedback.
- Work hands-on with customers to understand their environments, diagnose problems and turn bespoke requests into reusable capabilities.
What we're looking for
- 2 to 4 years of professional experience shipping and operating live software, with some of it in a fast-moving startup setting.
- Strong backend skills in TypeScript and Node.js, plus the ability to deliver across the full stack.
- Solid PostgreSQL knowledge and practical exposure to asynchronous processing or task orchestration.
- A self-directed approach and a history of seeing projects through from idea to launch on your own.
- An appreciation of why validating non-deterministic AI behavior calls for different methods than traditional unit tests.
- Comfortable working on-site in San Francisco.
Bonus points
- Early or founding engineering experience at a young company.
- Background building integration-heavy or API-driven products for business customers.
- Familiarity with enterprise AI, observability or distributed systems.
- Exposure to a fast-growing AI company.

- Base salary: USD 120,000 to 180,000 per year
