Senior Mechanical Engineer

Job Description

This Senior Mechanical Engineer role you will support both custom product modifications and new product development, evaluating customer requirements, performing engineering analysis, selecting motion control components, and leading efforts from concept through validation and production support. The position is ideal for an engineer who enjoys combining analytical design work with hands-on testing of electro-mechanical systems and motion control assemblies.

Responsibilities

• Evaluate customer requirements and translate them into clear mechanical and electro-mechanical design specifications.
• Perform engineering analysis using first principles, including structures, heat transfer, statics, dynamics, and motor sizing, to recommend sound design choices.
• Design and develop electro-mechanical assemblies and subassemblies for pan-and-tilt positioning systems and tripod products, rather than focusing solely on individual parts.
• Allocate approximately 40% of time to testing and analysis, including selecting motors, drives, sensors, and encoders through performance calculations and hands-on testing.
• Allocate approximately 30% of time to design and simulation, including CAD modeling (preferably in SolidWorks), structural analysis, and finite element analysis (FEA).
• Allocate approximately 30% of time to supplier and manufacturing support, including electro-mechanical component selection, supplier interaction, and resolving production issues.
• Develop and validate electro-mechanical systems, ensuring that precision motion control components such as encoders, motors, bearings, and supporting structures work together reliably.
• Specify and execute relevant tests, including those associated with MIL-STD-810, to validate component and subsystem performance under environmental and operational conditions.
• Lead projects from requirements elicitation through design, testing, production handoff, and after-sales support, ensuring technical integrity and timely delivery.
• Collaborate with cross-functional teams, including manufacturing and suppliers, to address design for manufacturability, troubleshoot production issues, and support continuous improvement.
• Support both new product development initiatives and custom product modifications to meet specific customer and application needs.
• Document designs, analyses, test plans, and results clearly to support ongoing product development, quality assurance, and future design iterations.

Essential Skills

• Bachelor of Science in Mechanical Engineering or an equivalent engineering discipline with adequate related experience.
• 5+ years of professional experience in a mechanical engineering role.
• Proven experience designing and validating electro-mechanical systems, particularly those involving motion control components.
• Strong technical thinking ability with a solid foundation in first principles, including structures, heat transfer, statics, dynamics, and motor sizing.
• Familiarity with full system architecture of precision motion control systems, including encoders, motors, bearings, and structural elements.
• Demonstrated ability to design assemblies and subassemblies, not just individual components, within complex electro-mechanical systems.
• Comfort with hands-on testing and validation of mechanical and electro-mechanical systems.
• Ability to perform performance calculations and interpret test results to inform design decisions.
• Experience supporting supplier and manufacturing activities, including component selection and resolution of production issues.
