About the role
AI Engineer - Ruby on Rails
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
