Mechanical / Propulsion Engineer

About Us

Liftero build rocket engines for new space era spacecrafts. With our first units already flying on SpaceX rideshare missions, we’re bringing BOOSTER - our next-gen thruster to small satellite missions.

We are an ambitious team of engineers and experts in field of propulsion and space systems. We move fast, stay focused, and keep things light. It’s a high-energy environment, but also a rewarding one - at Liftero, you’ll tackle meaningful challenges with people you actually enjoy working with.

We are looking for mission-driven people to join our team - builders, problem-solvers, and curious minds who want to shape the future of space mobility and see their work make it to orbit.

Position Overview

As a propulsion company, this role is central to everything we do. At Liftero, you'll play a key role in shaping our core product - BOOSTER - from early design and requirements definition to final deployment in orbit.

In space hardware, every detail matters - a single mistake can risk the entire mission. That’s why we put a lot of focus on defining solid requirements, grounded in both industry standards and Liftero’s own experience and best practices. The final design is just the tip of the iceberg - it’s built on deep technical preparation and careful planning

It’s a demanding role that comes with significant responsibility - but also the opportunity to grow and make a real impact.
