Full job description
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
What we’re looking for:
To succeed in this role, you’ll have:
Practical experience building with AI/LLM technologies, not just using AI tools casually
Strong Ruby on Rails experience, ideally at a senior level
Good judgment about when AI is useful and when simpler engineering is better
Strong backend skills, including databases, API design, performance, background jobs, and security
Ability to break down ambiguous problems into clear technical solutions
Nice to have:
CI/CD, background jobs, or AWS experience
Experience with text-processing, localization, translation, or multilingual products
