About the company

Our client is a fast-growing software company.

The role

Raydar is recruiting for this role on behalf of our client. Improve the quality and dependability of AI-driven software through structured testing and new feature development. Take promising experiments from prototype to maintained production code, collaborating with customers, researchers and domain specialists.

What you'll do

  • Find where automated AI systems fall short, then design and run evaluations to make them more dependable and efficient.
  • Build new capabilities for AI systems, including tool integrations, context handling, memory and multi-step workflows.
  • Analyze logs and experiment results to locate bottlenecks and separate genuine gains from measurement noise.
  • Work with customers and subject-matter experts to understand needs, then ship and maintain fixes end to end, typically within about 3 months.
  • Convert successful experiments into clean, maintainable production software.

What we're looking for

  • Solid background shipping and running live software in Python and a typed JavaScript language.
  • Practical exposure to LLM-powered systems, including how they are coordinated, observed and served at scale.
  • Comfort speaking directly with customers to clarify needs and deliver working technical answers.
  • Prior time at a demanding technology company or an AI startup.
  • A bachelor's-level technical degree in computer science, electrical engineering or a related field from a highly regarded school.
  • Clear communicator with good customer instincts and a knack for pinpointing the heart of vague technical problems.
  • Independent, driven and creative, with a sense of ownership and sound product instincts.

Bonus points

  • Curiosity about or exposure to chip design, semiconductors or hardware-software systems.
  • Relocation support
