Job Summary and Essential Duties

The Senior Mechanical Systems Engineer position is ideal for an engineer with strong mechanical design expertise and a background in high-precision system integration. The successful candidate will play a key role in developing mechanical assemblies and system enclosures for complex instrumentation and technology platforms. This is a primarily on-site role with travel requirements of approximately 10%, including visits to customer sites or participation in industry and professional conferences as needed.

Through on-the-job training (OJT) and professional experience, the Senior Mechanical Systems Engineer will:

• Lead or support the mechanical design of precision assemblies using SolidWorks or equivalent 3D modeling tools.
• Integrate components and subsystems into robust mechanical housings using proper alignment and tolerance strategies.
• Collaborate closely with design engineers to ensure system layouts meet performance, thermal, and mechanical requirements.
• Perform simulation and finite element analysis (FEA) using software to validate mechanical and thermal integrity.
• Interpret and apply results from structural, thermal, and performance analyses to guide design decisions.
• Develop and validate thermal models for high-performance equipment or imaging systems.
• Design custom fixtures and tooling for precision assembly, test, and environmental validation.
• Prepare and present technical review materials to customers and internal stakeholders.
• Support transitions from design to prototype and volume manufacturing.
• Assist in evaluating and selecting materials, vendors, and suppliers based on technical capability and quality metrics.
• Collaborate with cross-functional teams including Systems Engineering, Manufacturing, and Quality, throughout the product lifecycle.

Advancement through the Senior Mechanical Systems Engineer ranks is based on education, experience, technical skill, leadership ability, and demonstrated success in innovation and process improvement.

Minimum Requirements

• B.S. or M.S. in Mechanical Engineering or related technical discipline required.
• 5–15 years of experience in mechanical system design and analysis within a high-precision or advanced technology environment.
• Proficiency in SolidWorks or similar CAD tools for 3D modeling and mechanical drawings.
• Strong understanding of structural, thermal, and performance (S/T/P) analysis principles.
• Proven experience implementing designs with low-stress mounting or bonding techniques.
• Familiarity with simulation tools.
• Strong written and verbal communication skills with the ability to document and present technical data clearly.
• Ability to collaborate effectively within multidisciplinary teams.

Desired Experience

• Experience conducting detailed structural and thermal analyses for high-reliability or mission-critical systems.
• Background in semiconductor equipment, precision manufacturing, or other high-technology industries.
• Familiarity with ISO drawing standards and engineering tolerancing methods.
• Experience with environmental qualification testing (vibration, thermal cycling, or vacuum conditions).
• Prior experience as a project or program technical lead.
