Staff Mechanical Engineer
About The Position
Luna Health is seeking a highly motivated, experienced Staff/Principal Mechanical Engineer to serve as a hands-on technical partner to the VP of R&D and as the central integrator of the company’s hardware design. Luna Health is a venture-backed medical device startup developing insulin automation products. Its nighttime glucose-control product combines a small patch pump with a closed-loop insulin-dosing algorithm and has reached clinical studies. The engineer will own how the full hardware system comes together and carry it through verification and into volume manufacturing, with manufacturability and reliability considered from the outset. The role combines holistic product thinking—integrating user needs, risk analysis, mechanics, electronics, and industrial design—with hands-on detailed design, analysis, testing, and debugging. This is an on-site role. The successful candidate must live within a reasonable commuting distance of Luna Health’s San Diego, California site.
Requirements
- Bachelor’s degree in Mechanical Engineering or a related technical field.
- At least 8 years of mechanical product design experience, including medical devices or other safety-critical systems.
- Track record of taking a product from design through verification and into volume manufacturing, with manufacturability considered early.
- Experience acting as technical integrator across mechanical, electrical, industrial design, and user requirements on a complex hardware product.
- Experience designing mechanisms and moving assemblies.
- Hands-on expertise designing molded and machined parts and assemblies.
- Advanced use of tolerance analysis as a design tool.
- Working knowledge of design controls, verification and validation, risk analysis, biocompatibility, sterilization, and human factors.
- Ability to work across electrical, industrial design, regulatory, quality, and manufacturing disciplines.
- Strong organization and communication skills, including coordinating projects and budgets and aligning stakeholders.
- Experience mentoring engineers or leading small projects.
- Must live within a reasonable commuting distance of the Luna Health site in San Diego, California.
Nice To Haves
- Master’s degree.
- Experience with compact motorized electromechanical devices.
Responsibilities
- Integrate mechanisms, electronics, motion, fluidics, packaging, and user experience into a cohesive hardware product.
- Translate user needs into design requirements and decisions, collaborating with industrial design to create a functional and attractive product.
- Lead and contribute to risk analysis and use findings to guide design decisions and mitigations.
- Own the fit, integration, and interaction of electronics subassemblies within the mechanical system, working closely with electrical engineering.
- Design molded and machined assemblies, applying engineering judgment and tolerance analysis.
- Analyze, test, and resolve complex system-level issues using theoretical fundamentals and hands-on problem-solving.
- Work with regulatory and quality teams on design controls, verification and validation, risk analysis, biocompatibility, sterilization, and human factors.
- Partner with manufacturing engineering to transfer designs into production and continuously improve them.
- Independently gather latent requirements and develop well-reasoned plans.
- Coordinate projects, timelines, and budgets; communicate across functions and escalate when needed.
- Mentor more junior engineers and share experience as the team grows.
Benefits
- Equity.
- Excellent health benefits.
