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 you would do

* 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

What they are looking for

* CI/CD, background jobs, or AWS experience * Experience with text-processing, localization, translation, or multilingual products

* * *

Why Join OTGS?

* Stable & self-funded: Founded in 2007, profitable, and independent. * Industry leaders: Creators of WPML, the #1 multilingual plugin for WordPress, used on 1.5M+ sites * Fully remote, async-friendly: Work from anywhere within EMEA hours * Engineering-driven culture: Ownership, autonomy, testing, and thoughtful problem-solving * Fair compensation and great benefits: Designed to support your well-being both inside and outside of work.

Want to make a lasting impact on a product used by thousands of real customers? We would love to hear from you.
