Sr. Mechanical Engineer

Position Summary

The Senior Mechanical Engineer is responsible for leading the design and development of new products for both laboratory and demanding field environments. This role serves as a technical leader at the project level, driving mechanical design from the translation of customer and product requirements through final production handoff. This position offers a high-impact opportunity to shape both the technical direction of our products and the development of the engineering team.

Key Responsibilities

• Lead the design and development of electro-mechanical components, assemblies, and integrated systems.
• Serve as the technical owner for mechanical design decisions, ensuring alignment with performance, reliability, and manufacturing requirements.
• Provide technical leadership and mentorship through design reviews, day-to-day collaboration, and establishing best practices across the team.
• Lead cross-functional collaboration with electrical, software, manufacturing, product line management, and quality teams to translate requirements into engineering solutions.
• Support and drive project execution, including task estimation, schedule development, and technical risk identification and mitigation.
• Deliver designs from concept through prototype, validation, and production release in alignment with established development and quality processes.
• Drive effective use of structural, thermal, and flow analysis (analytical and FEA) to enable data-driven design decisions, ensuring appropriate modeling, simulation, and validation methods are consistently applied across projects.
• Define and lead comprehensive verification and validation efforts, including functional, environmental, and performance testing.
• Perform root cause analysis and implement corrective/preventative actions for development, production, and field issues.
• Identify, assess, and drive mitigation of technical risks throughout the product lifecycle.
• Lead and direct prototype builds, including hands-on development, rapid prototyping, and coordination with internal and external resources. Guide prototype iteration strategy to ensure efficient learning cycles and convergence to production-ready designs.
• Lead sustaining engineering efforts, including issue resolution, design improvements, and cost reduction initiatives.
• Drive application of DFM, DFA, DFT, and DFR principles, and work closely with Manufacturing Engineering to ensure successful transition from prototype to production.
• Interface with suppliers and external partners to support component selection, fabrication, qualification, and production readiness.
• Author and review engineering drawings, models, and documentation ensuring alignment with internal standards, product requirements, and applicable regulatory expectations.
• Drive consistency and standardization of engineering practices and outputs.

Qualifications

• Bachelor’s degree in Mechanical Engineering or related field. Sufficient combination of education and experience in lieu of a degree may be considered.
• 8+ years of experience in mechanical design, preferably in scientific instrumentation, sensors, industrial equipment, or related complex electromechanical systems.
• Experience designing products for challenging operating environments (temperature, humidity, vibration, contamination, ruggedization) preferred.
• Experience developing products in compliance with applicable regulatory standards (eg. UL, PED, CE, EPA) including working with requirements, documentation, and validation processes is a plus.
• Experience working directly with customers to define product requirements and translating them into practical solutions is a plus.
• Proficiency in 3D CAD (SolidWorks) and mechanical drafting. Experience with product lifecycle tools (PLM systems) preferred.
• Hands-on prototyping and test experience, including familiarity with machine shop tools and rapid prototyping methods. Background in manufacturing techniques such as CNC machining, sheet metal, injection molding, and/or additive manufacturing.
• Strong understanding of mechanics, materials, heat transfer, fluid dynamics, and general engineering principles. Experience with design for reliability (DFR), design for manufacturability (DFM), and working knowledge of FEA tools.
• Ability to author clear technical specifications, requirements, and test plans, and to review/approve engineering documentation.
• Excellent problem-solving skills and the ability to work both independently and collaboratively.
• Strong communication and presentation skills, including comfort participating in technical design reviews.
