Product Engineer

LoBio is seeking a Product Engineer to help design, build, and scale our next-generation blood testing platform. You will sit at the intersection of hardware, firmware, and user experience, working cross-functionally with R&D, process engineering, and operations to translate product requirements into robust, manufacturable, and delightful solutions.

• Own end-to-end product engineering tasks from concept through validation and release.
• Collaborate with scientists and process engineers to translate functional needs into mechanical/electromechanical designs.
• Develop rapid prototypes, run design experiments, and iterate based on performance data.
• Author and maintain design documentation, test procedures, and release notes.
• Support DFM/DFX efforts with external vendors and manufacturing partners.
• Instrument systems for data logging and performance analytics.
• Contribute to risk analysis (FMEA) and reliability testing plans.

• Bachelor’s degree in Mechanical, Electrical, Biomedical, or Product Engineering (or equivalent experience).
• Hands-on prototyping skills (mechanical assemblies, fixtures, test rigs, or embedded systems).
• Experience taking a product from concept/prototype to pilot or early manufacturing.
• Strong documentation discipline and version control familiarity.
• Ability to work cross-functionally in a fast-paced, resource-constrained startup environment.

• Experience with medical device development, life sciences tools, or regulated hardware.
• CAD proficiency (e.g., Solid Works, Fusion 360, Onshape) and basic simulation/FEA familiarity.
• Embedded/firmware collaboration (basic ability to interface with microcontrollers, sensors, or data acquisition tools).
• Comfort with structured experimentation, data analysis, and statistical thinking.
• Entrepreneurial mindset: bias for action, learning agility, and ownership.

Competitive salary + Stock Options (range to be finalized based on PDF details).
