The RoleAs a Mechanical Engineer, you will be at the heart of designing, prototyping, and testing mechanical systems for in-space 3D printing and deployable orbital structures. Your work will cover mechanical design, actuation, motion control, and supporting electrical integration. You’ll work hands-on with both ground-based prototypes and flight-ready hardware, contributing across the full development cycle.About the companyMy client develops breakthrough technologies that make manufacturing in space possible. Their 3D printing systems are designed to operate directly in orbit, enabling new possibilities - from compact CubeSats to large-scale interplanetary habitats. With three missions scheduled over the next two years, we’re moving fast toward real in-orbit deployment.What You’ll Do- Design and assemble mechanical systems for space-grade 3D printers and deployable structures, following ECSS standards.- Rapidly prototype and iterate using in-house tools (FDM/resin printers, CNC machines, lathes, testing rigs).- Integrate sensors, motors, actuators, and electronics with custom mechanical components.- Collaborate closely with electrical and systems engineers to ensure payload functionality.- Participate in environmental and functional testing (vibration, thermal vacuum, deployment).- Contribute to system-level reviews and mission documentation for ESA/NASA-class projects.What We’re Looking For- Degree or professional background in mechanical engineering, mechatronics, or electromechanical systems.- Prior experience in space-related projects or missions is a must have- Strong hands-on skills in rapid prototyping and hardware assembly.- Experience working in R&D environments where speed, iteration, and problem-solving matter.- Previous experience with space-related projects (CubeSats, payloads, subsystems, launch hardware) is a plus.- Familiarity with space-grade design standards (ECSS, NASA GEVS).- Proficiency with CAD (SolidWorks or Fusion 360).- Knowledge of thermal and structural analysis (simulation or test).- Willingness to relocate to Warsaw, Poland (on-site role).What We Offer- Hardware that goes to space - your designs will fly within 12–24 months.- End-to-end ownership - take ideas from concept through design, prototyping, testing, and delivery.- A unique engineering environment - printing in microgravity, structures unfolding in vacuum, real missions in orbit.- A talented, close-knit team – low-ego, high-talent engineers working fast and building for real.- Relocation support - we’ll help with moving to Warsaw, finding housing, and handling formalities.- Competitive salary & equity – plus a real stake in a company pioneering the future of space construction.- Client offers B2B or umowa o pracęJoin them! and help shape the future of space engineering.
