Senior Mechanical Engineer - Piezo

Job Description

Your Mission \n
\n
\nWe are seeking a highly motivated and experienced Senior Mechanical Engineer - Piezo to join our engineering team. The Senior Mechanical Engineer's role is to design, develop, and optimize high-precision mechanical systems and motion instruments from concept through production, providing robust, high-performance solutions that meet demanding requirements for accuracy, stability, reliability, and manufacturability.\n
\n
How you will make a difference \n
\n
\n

\n
• Lead the design and development of mechanical components, subassemblies, and system architectures for high-precision motion instruments across full product development cycles.
\n
• Own mechanical design execution from concept through production release, including technical decision-making and design validation.
\n
• Develop advanced 3D CAD models, detailed engineering drawings, and complete design documentation with full adherence to precision tolerance and GD&T standards.
\n
• Perform and lead engineering analysis including tolerance stack-ups, error budgets, and FEA (thermal, structural, and modal) to ensure system-level performance and stability.
\n
• Design precision mechanisms, motion systems, and opto-mechanical assemblies, including kinematic structures, flexures, and thermally stable architectures.
\n
• Design monolithic flexures (often via wire EDM) using CAD software and using ANSYS or SolidWorks to optimize for high resonant frequencies, thermal stability, and stress-strain limits.
\n
• Choose the right piezoelectric materials and sizing them for optimum stiffness, blocking force, and displacement.
\n
• Design systems with closed-loop feedback-typically employ capacitive, strain gauge, or laser interferometer sensors-to eliminate hysteresis and creep.
\n
• Program and tune PID controllers or digital algorithms to ensure maximum bandwidth and minimal parasitic motion (pitch, yaw, and roll).
\n
• Lead prototype development, assembly, integration, and testing of motion systems, driving iterative design improvements based on test data.
\n
• Oversee system-level integration, alignment, and performance verification, with emphasis on accuracy, repeatability, drift, and environmental sensitivity.
\n
• Collaborate closely with electrical, controls, manufacturing, and cross-functional teams to ensure seamless system integration and manufacturability.
\n
• Evaluate and resolve complex engineering challenges, making independent technical decisions and trade-offs to meet product requirements.
\n
• Ensure design intent, test results, and engineering decisions are thoroughly documented to support traceability, quality, and production readiness.

\n
What you should be good at \n
\n
\n

\n
• Minimum five years of experience in mechanical design, product development, or mechatronic systems, with significant exposure to precision motion or high-performance mechanical systems .
\n
• Bachelor's degree in mechanical engineering or closely related field required; master's degree preferred.
\n
• Demonstrated experience designing and releasing mechanical systems from concept through production in a product development environment.
\n
• Strong proficiency with 3D CAD software (SolidWorks preferred) for complex assemblies, detailed design, and engineering documentation.
\n
• Experience with precision manufacturing processes such as CNC machining, tight-tolerance fabrication, and assembly methods.
\n
• Familiarity with design control processes, PDM systems, and engineering change workflows.
\n
• Experience working within ISO 9001 or similarly structured quality systems; familiarity with lean/5S principles.
\n
• Due to ITAR regulations, applicants must be U.S. citizens, lawful permanent residents (Green Card holders), or protected individuals as defined by 8 U.S.C. 1324b(a)(3).
