Our client is a fast-growing software company.
The role
Raydar is recruiting for this role on behalf of our client. Join a very small engineering group as an early hire, working across the front end, back end and infrastructure of a customer-facing software product. You will ship features, diagnose production issues and help set technical standards for future engineers. Expect broad ownership with little prescribed structure.
What you'll do
-
Build and ship features across the full stack, from user interface to backend services.
-
Develop and refine systems built on large language models, including conversation flow, tool use and voice.
-
Prototype adaptive interface components and turn ideas into working demos quickly.
-
Build and maintain an evaluation pipeline that measures output quality and catches regressions.
-
Investigate production issues by reviewing logs, tracing root causes, rolling back changes and adding tests.
-
Design infrastructure for versioning and safe previewing of changes before release.
-
Create low-latency, reliable infrastructure so users get instant responses.
-
Take on whatever work is needed, including UI fixes, data migration scripts and customer issue debugging.
-
Help establish engineering culture and practices as the team grows.
-

Hands-on delivery of AI-powered features in production, such as LLM-driven assistants, retrieval pipelines or orchestration layers.
-
A bachelor's degree in computer science.
-
Comfort with ambiguity and a strong sense of ownership.
-
Good product instincts and enthusiasm for turning user feedback into code.
-
Sound judgment about when work is ready to ship, and the ability to move quickly without creating hidden problems.
-
Experience running systems that real users depend on, and an understanding of how they fail.
