Principal Product Design Engineer

About This Role

Serve as a technical authority in the design and development of rugged electro-mechanical sensors for industrial fluid sensing and control applications. This role combines hands-on design with engineering mastery of mechanical fundamentals to translate complex requirements into manufacturable, reliable, and high-performance products and drive cross-functional development of integrated sensor systems.

Responsibilities

• Convert customer requirements into engineering requirements, design objectives, and comprehensive design specifications.
• Lead mechanical design of sensor components and systems with tight tolerance control and robust structural integrity.
• Utilize 3D CAD modeling and simulation tools to evaluate stress, vibration, heat transfer, and fluid flow characteristics.
• Develop material selection criteria emphasizing liquid compatibility, thermal stability, corrosion resistance, mechanical durability, and manufacturability.
• Specify and optimize manufacturing and assembly processes including injection molding, CNC machining, die casting, stamping, welding, crimping, over-molding, and adhesive bonding.
• Design leak-tight sealing systems using O-rings, gaskets, and welded joints.
• Define and execute mechanical and environmental validation plans to verify performance, reliability, and compliance with industrial standards, constructing prototypes for testing.
• Collaborate closely with electrical, firmware, and manufacturing teams, leading cohesive integration of subsystems.
• Author and publish comprehensive engineering documentation, including detailed engineering drawings, design specifications, and failure analysis reports.
• Apply core engineering principles—thermal analysis, fluid mechanics, strength of materials, and material science—throughout all development phases.
• Assess and integrate the latest technological developments by researching industry trends and academic sources.
• Mentor junior engineers and contribute to continuous improvement of mechanical design methodologies and product development best practices.

Requirements

• Bachelor’s degree in Mechanical Engineering
• 10+ years of hands-on mechanical design experience
• Expert proficiency in 3D CAD (SolidWorks preferred) and simulation tools (FEA/CFD)
• Proven experience in design for manufacturability (DFM) and design for assembly (DFA)
• Strong background in mechanical design, fluid dynamics, thermodynamics, and mechanical behavior of materials
• Established skills in sealing system design for high-reliability sensor housing, Ingress Protection (IPx) ratings, and pressure-rated assemblies
• Familiarity with industry standards and regulatory compliance (CE, UL, CSA, ASME, ISO, ASTM, MIL-STD)

Qualifications

• Bachelor’s degree in Mechanical Engineering
• 10+ years of hands-on mechanical design experience, ideally in industrial instrumentation, electro-mechanical devices, or precision systems.

Nice to Have

• Master’s degree in Mechanical Engineering
