## Description

Our Intelligence team builds the AI capabilities that run across the whole Tellent suite. We're looking for a backend-heavy product engineer who can take a fuzzy "AI should help here" idea and turn it into an interface people actually trust and use.

You'll own problems end to end: shaping, building, shipping, and checking whether it moved anything. Your 12-Month Journey:

- First 3 months: You'll get to know the team, our product, and our architecture while contributing to your first meaningful improvements.

- Within 6 months: You'll take ownership of features and contribute to technical discussions, code reviews, and improvements to the scalability, reliability, and maintainability of the platform.

- After 1 year: You'll be a trusted technical partner within the team, taking ownership of significant parts of the product and contributing to technical decisions and architectural discussions.

Responsibilities:

- Building AI-powered features into mature products with real users.

- Working across the stack when the problem demands it.

- Take ownership of the features you deliver, ensuring they are well-tested, maintainable, and meet our quality standards.

- Collaborate closely with Backend and Frontend Engineers, Design, QA, and DevOps to solve complex problems and deliver valuable product improvements.

Requirements:

- Commercial experience with Elixir, or strong backend development experience in technologies such as Ruby on Rails, Python, Java, or PHP combined with a strong motivation to learn Elixir.

- Experience with Typescript and Mastra or strong willingness to learn it.

- Senior-level judgment: you have shipped enough to know when good enough is good enough.

- Product thinking: you push back on specs, evaluate trade-offs, prototype cheaply, kill your own ideas when data says so.

- Interest in building with AI: hands-on LLM/feature experience is a plus, curiosity and shipped experiments count too.

- Communication: fluent English, Polish is a plus.

Benefits:

- Hybrid or remote working setup across Amsterdam, the Cologne area, or Poland.

- A chance to shape one of the most ambitious scale-ups in Europe and lead a company-defining tech transition.

- Work in a diverse, multicultural, and remote-friendly team.

- €1,500 annual training budget + 2 dedicated learning days.

- Pension plan, travel reimbursement, and wellness perks.

- 28 paid holiday days + 2 additional days to relax.

- Work from anywhere for 4 weeks/year.

- Apple MacBook and top-tier tooling.

- €200 home office budget.
