Senior Mechanical Engineer I - OXOS Medical

In-Person

OXOS builds radiographic imaging devices that give providers the capability and confidence to make accurate decisions at the point of need. As we scale, we're hiring a senior mechanical engineer to own the mechanical and electromechanical design of our devices. You'll be the person who takes a major subsystem from a concept sketch all the way to a production-released, manufacturable, reliable product.

This is a hands-on senior IC role. You'll lead the mechanical design of integrated products that pack PCBAs, sensors, detectors, and batteries into tight enclosures. You'll run the structural and thermal analysis that proves those designs out. You'll drive injection-molding and machined-part DFM with our vendors, and you'll coach our junior engineers along the way. You'll also lead the mechanical integration of our next-generation surgical platform.

If you've brought an integrated product to market, and you've actually wrenched on, machined, and tested your own designs instead of just speccing them out, we should talk.

What This Person Will Do

Own major mechanical subsystems end to end. Lead the design of complex mechanical components and electromechanical assemblies for our devices and accessories, from sketches through functional prototypes to production units. Lead the mechanical and electromechanical integration of our next-gen surgical platform, packaging boards, sensors, and battery envelopes into one integrated product.

Run the analysis and the testing. Lead structural and thermal analysis (hand calculations, FEA, simulation) to converge designs and retire risk before release. Plan and lead mechanical V&V, much of it driven by the IEC 60601-1 mechanical requirements. Use our reliability and cycle-test rigs to prove designs are repeatable, then iterate on what the data tells you.

Make it manufacturable. Drive DFM and DFA so parts come off the line easily, repeatably, and in tolerance. That means deep injection-molding expertise, plus sheet metal, CNC, laser cutting, and 3D printing. Qualify and manage the vendors who build those parts, and own production transfer and sustaining engineering on released designs.

Work across the electrical boundary. Our products are tightly integrated, so you'll work hand in hand with our EE team. You'll define enclosures and battery envelopes, and you'll give the EEs concrete feedback (board outline, screw and plated-through-hole placement, layer stackup) to make boards fit, hold tolerances, and manage heat and vibration.

Raise the team's bar. Coach junior engineers on DFM and tolerance analysis, review and sign off on their drawings, and set the standard for documentation. Use AI tools to speed up documentation, research, scripting, and design exploration.

What We're Looking For

Required:

• 6 to 10 years of professional experience in mechanical product design and development, including products you took to market (which forces real DFM and DFA work).
• Bachelor's degree in Mechanical Engineering or a closely related field.
• Expert proficiency in 3D CAD (SolidWorks preferred) and in 2D engineering drawings per ASME Y14.5 (GD&T).
• Strong knowledge of manufacturing processes, injection molding especially, plus sheet metal, CNC machining, laser cutting, and 3D printing, with the ability to drive DFM decisions.
• Hands-on fabrication and lab experience. You've personally built, machined, and tested your designs, not just written specs.
• Proven ability to perform hand calculations and FEA, with structural and thermal analysis experience.
• Experience with electromechanical and integrated products (PCBAs, batteries, motors, cabling, enclosures), and working directly with electrical engineers.
• Experience in a standards-driven or regulated industry (medical, automotive, aerospace, or other ASME or IEEE work). You're comfortable reading, deciphering, and applying standards.
• Strong written and verbal communication, and a track record of cross-functional, multidisciplinary work.
• Experience providing technical guidance to junior engineers.

Preferred:

• Exposure to IEC 60601-1 and relevant collaterals. You can learn the specifics; we're looking for the standards mindset.
• Familiarity with eCAD-to-mCAD handoff tools (e.g., Altium and SolidWorks connectors) and a working understanding of PCBA fabrication.
• Familiarity with FDA design controls and ISO 13485, and product development in a design-controlled environment.
• Experience with PLM or PDM systems for document and BOM management.
• Exposure to manufacturing support: fixture design, process validation (IQ/OQ/PQ), or production line troubleshooting.
• Experience using AI or ML tools to speed up engineering work.

About Working Here

OXOS is a small, lean team, and this role touches nearly every part of the product. You'll work with our electrical engineers on integration, with vendors on manufacturing, and with product and systems on requirements. It's a lot of surface area, and not every problem arrives well-defined. The people who do well here are persistent and resourceful. They don't drop a problem because it's hard or ambiguous, they find a way forward, and they hold themselves to a high standard without being asked.
