Job description

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.

Your Daily Impact

• Develop detailed technical specifications and designs for thruster systems.
• Perform analyses, simulations, and tests to verify thruster component designs.
• Develop test stands for individual subsystems and entire propulsion system testing including thrust balance, TVAC stands,
• Plan and oversee the manufacturing and integration of thruster assemblies.
• Execute comprehensive testing and verification plans for thruster performance.
• Analyse test results, report on performance, and ensure compliance with specifications and standards.
• Assess technology development needs and drive market readiness efforts.

Is This You?

• Hands-on experience in planning and executing tests in the laboratory conditions.
• Proficiency in CAD software, such as SolidWorks, Onshape, or similar.
• Strong analytical thinking, problem-solving, and decision-making skills
• Excellent communication and collaboration skills, with experience working in cross-functional teams
• Space industry experience especially in a field of propulsion systems is a strong plus
• Multisport membership
• Courses and Trainings financing
• Stock options

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.
