Job Description

Job Title: AI/ML Engineer

Location & Setup Hybrid: Porto, Portugal

At RemoteStar, we’re hiring for one of our clients who are building AI systems that support real-world industrial decisions not chatbots, not demos.

These are systems where reasoning quality has direct financial impact.

We’re looking for a Founding Agent / LLM Engineer to architect and scale next-generation agent infrastructure from the ground up.

You might be a great fit if you:

  • Have built complex AI systems in production
  • Designed agent architectures before they were mainstream
  • Have a track record in competitive programming / ML / math
  • Have shipped systems at scale
  • Built open-source tools others actively use
