Job description

Junior/Intern - 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

A few years ago, we were building student space technologies at the AGH just like you

Today, at Liftero, we design and build satellite propulsion systems that are already flying in space on our demo mission and on board our clients' satellites.

We are now opening intern and junior positions for candidates who are looking for adventure.

This is an on-site role in Krakow, where you will work hands-on with flight hardware. We’re flexible with hours and workload, so you can join part-time during your studies or full-time if you’re ready to dive deeper.

Your Daily Impact

• Design, assemble and test propulsion system components (thrusters, valves, feed systems)
• Support integration and qualification campaigns for flight hardware
• Create and verify CAD models and technical documentation
• Work side-by-side with experienced engineers from mechanical, electronics and software teams
• See your work become part of a system that will fly to orbit

Is This You?

• You love working with real hardware and solving technical problems
• You’re comfortable with CAD (SolidWorks / OnShape)
• You enjoy building, prototyping and testing
• You’d love to see something you designed end up in space
• Multisport membership
• Courses and Trainings financing
• Unlimited fresh grinded coffee

What Its Like to Work With Us

Working at Liftero is meaningful, fast-paced, and human. We’re not trying to copy corporate culture or pretend that work is your second home - we respect your time, your life outside of work, and the fact that we’re all just people. If you're having a tough day, say it - we’ll work it out. If you’re in flow and want to build through the night, we trust you to manage your own time.

Building serious space tech takes focus, dedication, and real effort. It can be demanding - but it’s also where you’ll grow, both professionally and personally.

We’ve created a unique company culture that’s shaped by mutual respect and a shared drive to build things that fly. Whether you’re loud and all-in, or more quiet and independent - there’s space for you here.

We work in our own project management framework, refined over years of iteration. It helps us move quickly, stay flexible, and give every team member a real voice in shaping the final product.
