AI Engineer - Ruby on Rails

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

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.
