AI-Native Software Developer at OnTheGoSystems · Zagreb

About OTGS

At OnTheGoSystems, we build products used by hundreds of thousands of websites worldwide. We're a fully remote, international team that values ownership, curiosity, and high engineering standards. We use AI every day to solve real problems and build software that makes a difference.

About the role

We're looking for a developer who can do impressive work end-to-end – from idea to shipped, working software – using AI as a system, not as a chat window.

You take full ownership of the software you build. You design AI workflows and validation checks, ensure quality, monitor how your software performs in production, and continuously improve both the product and the way AI helps you build it.

• Experience with Ruby on Rails or other back-end languages and frameworks.
• Profound SQL experience – comfortable designing schemas and writing complex queries.
• A habit of testing your own work and genuine care about the quality of what you ship.
• Real, hands-on experience using AI as a system to do end-to-end work, with something impressive to show for it.

You'll work on real AI systems used by customers around the world and directly influence how we measure and improve machine translation quality.

This role is ideal for someone who enjoys exploring difficult questions, testing ideas, and discovering insights that aren't immediately obvious. You'll have the freedom to propose your own analyses and the responsibility to turn them into evidence-based recommendations.

• A Kindle device with access to our company Amazon account,
• We respect national holidays in each country and want you to have a rest these days,
