Full-Stack Software Engineer

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.

Requirements

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.
