THE OPPORTUNITY — Who we are

We are building the aerospace company that gives Europe independent, sovereign access to air and space.

For decades, Europe's ability to design, build, and launch its own critical aerospace and defense systems has quietly eroded, leaving the continent dependent on others for capabilities that decide its security and autonomy. Momentum Aerospace exists to reverse that. We build the hardware and systems that put strategic capability back in European hands.

We're a small, deliberately senior team of builders, engineers and operators who have shipped real flight hardware and who would rather own a hard problem end to end than sit inside a large prime's process. We're early, we're moving fast, and the decisions made in the next few years will define whether Europe controls its own aerospace future.

You'll join a team that measures itself against what actually flies, not what fits in a slide.

YOUR MISSION — The problem you will solve

Our electronics are only as good as the mechanics that keep them flying. Flight hardware has to survive vibration, thermal cycling, and harsh environments, and that's exactly where you come in, at the interface between electronics and mechanics. As a Mechanical Intern in the Electronics team, you'll build the enclosures, mounts, and mechanical solutions that make our avionics flight-ready.

Your role:

• You'll design mechanical parts for our electronics: enclosures, mounts, brackets, and harness mechanics - in CAD, and take them all the way to a part in your hand.

• You'll own the hard problems at the interface: thermal management, vibration, tolerances, and the manufacturability and assembly of our avionics hardware.

• You'll build prototypes, test them on the bench, and iterate fast — from 3D printing to working with manufacturing and suppliers.

• You'll document cleanly, so your prototype can become real flight hardware.

Why this matters: Every bracket that holds and every enclosure that survives its environment helps decide whether our electronics make it in the field. Your work flies.

What success looks like: By the end of your internship, you'll have designed, built, and tested mechanical parts that are actually in our hardware — not in a drawer, but in the system.

WHO YOU ARE — Your mindset

You are the type of person who:

• Thinks like an owner. You don't wait for detailed instructions; you identify what needs to be done and figure out how to solve it exceptionally well.

• Operates well under real stakes. Deadlines, ambiguity, and consequential decisions focus you rather than unsettle you.

• Executes with startup speed. You go from insight to implementation in days, not weeks, and you'd rather have a part in your hand than a perfect theory.

• Holds a high bar. For your own work and for the people around you.

• Shows off results, not the third concept paper.

Your track record

You've already shown that you build things: through university projects (e.g. Formula Student, rocketry, robotics), your own side projects, or a first internship where you got your hands on real hardware.

Must-haves

• Ongoing studies in mechanical engineering, mechatronics, aerospace engineering, or a related field.

• Confident with a CAD tool (e.g. SolidWorks, Fusion 360, CATIA, or Onshape).

• A solid grasp of manufacturing methods (3D printing, CNC, sheet metal) and a genuine urge to build and test things yourself.

• Bonus: first experience with thermal, vibration, or the mechanical design of electronics enclosures.

• Good English; German is a plus.

• Able to work from our office 5+ days/week (with some flexibility).

WHAT WE OFFER

• Competitive compensation: A fair, competitive internship salary.

• A young, nerdy, burning team and true ownership: A flat structure with direct access to the founders and engineers, no bureaucratic layers in between. You get a real project that's yours. From concept to a part that ships.

• Work with genuine stakes: Your work has a direct, visible impact on real flight hardware. And on Europe's ability to build its own aerospace capability.

We're an early, ambitious team building hard technology on a tight timeline. We push hard, move fast, and hold a high bar. And we back the people who do the same. If you want deep ownership, real stakes, and the chance to help build something that matters to a continent, this is the place to do it.
