Mechanical Engineer

About the role

FEI is seeking a mechanical engineer who thrives in environments where the path is not fully defined, the problems are new, and the solutions require creativity, rigor, and teamwork. Our products span precision oscillators, advanced atomic clocks, and emerging quantum-sensing technologies. These systems demand thoughtful mechanical design, deep curiosity, and a willingness to explore new methods in analysis, testing, and manufacturing.

Responsibilities

• Design mechanical components and assemblies for high-reliability electronic systems, from concept through detailed CAD models and drawings.
• Perform structural and thermal analysis using tools such as ANSYS Mechanical, Icepak, or equivalent numerical methods, complemented by hand calculations and first-principles reasoning.
• Prototype, test, and iterate on new designs, including hands-on work in the lab to evaluate mechanical and thermal performance.
• Collaborate closely with electrical, firmware, manufacturing, and test teams to solve cross-disciplinary challenges and ensure cohesive system performance.
• Apply design-for-manufacturing principles including tolerance analysis, fastening methods, machining processes, and material selection.
• Investigate new technologies and methods, bringing fresh ideas and research to support next-generation products.
• Contribute to continuous improvement, including documentation, process refinement, and team knowledge-sharing.
• Support the team wherever needed, especially during critical project phases, even when tasks fall outside traditional mechanical engineering boundaries.

Requirements

• A bachelor’s or master’s degree in mechanical engineering or a related field.
• Strong fundamentals in mechanics, heat transfer, materials, and engineering fundamentals.
• Experience with CAD tools (Autodesk Inventor or similar).
• Exposure to FEA, CFD, or thermal modeling tools, or the ability to learn them quickly.
• Familiarity with manufacturing processes and mechanical design best practices.
• Ability to break down ambiguous problems, research unfamiliar topics, and propose practical solutions.
• Clear communication skills and a collaborative mindset.

Qualifications

• Nice to have: Experience with electronics packaging, precision machine design, or high-reliability systems.
• Programming or scripting skills for analysis automation or data processing.
• Hands-on prototyping or lab experience.
• Familiarity with thermal or structural testing methods.

Skills

• Strong problem-solving skills.
• Attention to detail.
• Team player with a collaborative mindset.
• Ability to learn and apply new technologies quickly.

FEI offers a comprehensive benefits package that includes Medical, Dental, Vision, Flexible Spending Accounts, and a 401(k) plan with a 6% company match in company stock. We also provide a very generous paid time off policy, along with 11 paid holidays. In addition, we operate on a 9/80 work schedule, which gives employees every other Friday off. This schedule includes longer workdays—9 hours and 45 minutes with a mandatory 45-minute lunch break. One week consists of four workdays (36 hours), and the following week includes five workdays (45 hours). Despite this variation, employees are paid for a consistent 40-hour workweek, with weekly pay.
