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

Requirements

Do you have experience in WordPress?, Do you have a Master’s degree?, 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
