Senior Mechanical Engineer (Medical)

What you'll do

We're looking for a Senior Mechanical Engineer for Midjourney Medical — from precision electromechanical assemblies up to the large-scale structures and mechanisms that hold everything together and make it move. This role spans the full range of scale: one week you might be refining a compact transducer mount, the next you're architecting a structural frame or designing the motion system that positions hardware within it.

This is a hands-on role on a small cross-functional team. You'll take problems from whiteboard sketch to working hardware yourself — designing in CAD, prototyping in the shop, testing, iterating, and integrating with research teams, electrical and software engineers along the way. We move fast and expect you to drive your own work: identifying what needs to happen next, making sound engineering calls without waiting for permission, and shipping hardware that works.

• Own parts of the mechanical systems end to end — structures, mechanisms, and electromechanical integration

• Design large-scale structures: frames, weldments, enclosures, and support systems, with attention to stiffness, weight, manufacturability, and serviceability

• Design mechanisms: linkages, motion stages, actuation systems for precise, reliable positioning and articulation

• Integrate transducers, electronics, cabling, and thermal management into large physical systems

• Perform engineering analysis (tolerance stack-ups, structural/FEA, mechanism kinematics) to de-risk designs before committing to hardware

• Build and test relentlessly — 3D printing, rapid prototyping, and hands-on fabrication are core to how you'll validate designs

• Select parts and materials for system-level integration, balancing performance, cost, and lead time

• Drive projects independently from concept through validation, and collaborate closely with a small cross-disciplinary team to hit project goals

What we're looking for

• Bachelor's degree in Mechanical Engineering or a related field

• 5+ years of experience designing and shipping electromechanical hardware

• Demonstrated track record in mechanism design — you can point to mechanisms you've designed that work reliably in the real world

• Experience designing larger-scale structures (frames, gantries, enclosures, or similar), not just component-level parts

• Proficiency in CAD (we use OnShape) for design, optimization, and system integration

• Strong rapid-prototyping experience — this is a must; you should be as comfortable in the shop as at your desk

• Background in R&D environments where the problem isn't fully defined and the path forward is yours to figure out

• Excellent creative problem-solving and analytical skills

• Experience working closely with a small cross-disciplinary team
