We are looking for an engineer with practical AI/LLM experience who can build production features in Ruby on Rails.
This role is for someone who has worked with AI tools, LLM APIs, prompts, retrieval/context patterns, or AI-assisted workflows - and who also has the engineering depth to turn those ideas into reliable, tested, maintainable software.
What you’ll be working on:
- Designing and building AI/LLM-assisted product features
- Integrating LLM APIs into Ruby on Rails systems
- Combining AI approaches with business logic, tests, fallbacks, and production safeguards
- Owning features from technical design to production
- Improving reliability, accuracy, consistency, latency, cost, security, and maintainability
- Writing and maintaining automated tests, including unit, integration, and E2E tests
- Debugging production issues and improving system behavior over time
