What we’re looking for

We’re hiring a Junior Mechanical Engineer – Hands-On Innovator who loves turning ideas into real, working hardware. This is a practical, build-focused role for an early-career engineer who enjoys designing, prototyping, assembling, and iterating on mechanical systems—from UAV components to production-ready parts. You’ll blend solid engineering fundamentals with hands-on problem-solving and learn fast in a real-world environment.

The day-to-day

Design mechanical components and assemblies for UAV platforms and related systems.
Build, test, and iterate on prototypes using 3D printing and hands-on fabrication.
Support the transition from prototype designs to production-ready parts.
Assemble mechanical and electromechanical subsystems, including basic soldering work.
Work closely with electronics, autonomy, and operations teams to solve practical integration challenges.
Learn and apply DFM/DFA principles as designs mature toward manufacturing.

You should apply if you

Are a graduate or early-career engineer (0–2 years) with a bachelor’s or higher in Mechanical Engineering or a related field.
Are curious, practical, and motivated to build, test, and improve real hardware.
Are comfortable moving between CAD design and hands-on bench work.
Enjoy learning by doing and iterating quickly based on real-world feedback.
Are eligible to obtain a NATO security clearance.

Nice to haves

Proficiency in SolidWorks.
UAV piloting experience.
Exposure to PX4 or other drone control stacks.
Deeper knowledge of 3D printing (materials, optimization, troubleshooting).
Experience with plastic injection molding and DFM/DFA principles.

What we offer

Competitive salary and equity options.
A hands-on role contributing directly to next-generation UAV platforms.
A collaborative, ambitious, and engineering-driven startup environment.
Flexible working conditions with remote work and relocation support for top candidates.
