Junior Product Engineer

Berlin
Full-time
Permanent employee

Your mission

You'll join our product and engineering team at the intersection of customers and code. This isn't a classic PM role - you'll work hands-on with some of the most senior engineers we have, helping build our GPU cloud and inference platform end to end. You'll figure out what needs to be built, talk to the customers using it, and help ship it.

We're moving fast on all fronts. You'll have real ownership from day one.


What You'll Do

  • Work directly with senior engineers to build and improve our inference platform - from API design to customer-facing features
  • Talk to ML engineers and AI companies using our platform - synthesise their feedback into product decisions
  • Write specs, user stories, and acceptance criteria for new features
  • Identify friction points in the product through usage data and customer conversations
  • Coordinate between engineering, GTM, and support to ensure smooth feature launches
  • Contribute directly to the product roadmap - your input shapes what gets built next

Your profile

You're technically curious and move fast. You're comfortable sitting in a customer call in the morning and reviewing a pull request in the afternoon. You don't wait to be told what to build - you figure it out.

  • Degree in Computer Science, Engineering, or a related field (or equivalent hands-on experience)
  • First experience in product, engineering, or a startup environment
  • Genuine curiosity about cloud infrastructure, developer tools, or AI/ML
  • Strong communication skills - you can talk to an ML engineer and a sales lead in the same afternoon
  • Bias toward action: you ship, not just plan
  • Based in Berlin or willing to relocate

Why us?

  • Outstanding team: Work with some of the best engineers in the world, coming from hedge funds, big tech, AI startups, and top universities
  • Once in a lifetime opportunity: Early-stage company in the fastest-growing market in the world
  • Ownership: Shape how European AI companies access GPU compute
  • European mission: Build sovereign, GDPR-compliant AI infrastructure for the next generation of deep-tech
