o Design: de-sensitize optical designs to environmental influences (e.g. thermal, vibration, atmospheric).
o EDA Tools: SolidWorks, FEA, Zemax.
o Reliability: de-rating analysis, Six Sigma (DFSS), failure analysis, physics-of-failure.
o Regulations: IEC 60601-1, IEC 60601-1-2, ISO 14971, FDA cGMP, QSR, ISO 13485, EU MDR, etc.
o Solid Mechanical Engineering fundamentals and problem solving skills up through system-level.

• Documentation:
o Schematics, architecture documents, requirements documents, technical reports.
o Characterization procedures, test procedures, and test fixtures.
o Verification & validation plans, protocols, and reports.
o Project plans, project schedules, risk / benefit / cost analysis.

• Process:
o Design control, quality system, risk management, dFMEA, PDP, CAPA.
o Mechanical design process from concept to architecture to volume production.
o Prototype bring-up and debug, bug tracking, functional verification, performance characterization.
o System development process - concept, schematics, system bring up and debug.

• Work habits:
o Strong communication and presentation skills.
o Communicate ideas and issues effectively to other team members and management.
o Participate in project teams in NPI, failure investigations, sustaining engineering, etc.
o Strong multidisciplinary collaboration experience - EE, Optics, SW, ME, SE, QA, RA, Marketing, Clinical, etc.
o Experience with team collaboration and project management tools.
o Work in a matrixed environment to meet company objectives.
o Actively learn to become the domain expert on our gas sensing devices.

Essential Functions:
• Participate in project teams in NPI, failure investigations, sustaining engineering, etc.
