Senior Mechanical Engineer - MSP

TSI, Inc. • Shoreview, MN

6d • $105,000 - $120,000 • Onsite

About The Position

The Senior Mechanical Engineer is a senior engineer who independently solves complex problems in the design, development, and manufacture of products for MSP, a division of TSI, with emphasis on MSP's wafer deposition systems. These automated semiconductor tools generate, size-classify, and deposit particles onto wafers for inspection-tool calibration. System design consists of integrating a wafer-handling robot with MSP-designed aerosol generation and classification, controlled airflow and vacuum, and cleanroom-compatible frames and enclosures in large, complex assemblies. MSP's products also include aerosol instruments, pharmaceutical impactors, and liquid and vapor delivery systems. This role leads the mechanical portion of development projects, integrating structural and flow-path design with the electrical, controls, and software disciplines. The Mechanical Engineer III communicates effectively across engineering, manufacturing, quality, service, marketing, and sales, and with customers.

Requirements

• Bachelor's degree in Mechanical Engineering
• If a Master's degree in Mechanical Engineering is held, substitutions may be made for the Bachelor's degree.
• 5+ years of product development mechanical engineering experience
• Expert-level 3D CAD experience (SolidWorks preferred), including design and management of large, complex assemblies and detailed drawings
• Designing sheet-metal, machined, and welded parts and assemblies
• Taking mechanical designs from concept through release to production
• Mechanical engineering fundamentals, including strength of materials, heat transfer, and fluid mechanics
• GD&T (ASME Y14.5) and tolerance analysis
• Test and validation methods and engineering data analysis
• Microsoft Office, including advanced Excel
• Engineering standards (e.g., ASME, ANSI, ASTM)

Nice To Haves

• Master's degree in Mechanical Engineering, preferably with emphasis in machine design, mechatronics, or fluid mechanics
• Expert knowledge generating and managing configurations in SolidWorks and/or experience with complex assemblies and detailed assembly drawings including exploded views
• Leading the mechanical portion of development projects and mentoring other engineers
• Semiconductor capital equipment, including familiarity with wafer-handling robots, FOUP load ports, and aligners and their integration
• Aerosol or particle instrumentation (including impactors), vacuum, or high-purity gas and liquid delivery systems
• Design of precision welded stainless steel frames and chassis, and industrial design of housings
• SolidWorks and SolidWorks PDM
• FEA and CFD tools (e.g., SolidWorks Simulation, ANSYS)
• SEMI safety and wafer-handling standards (e.g., SEMI S2, S8, E15.1, E47.1, E84)
• Cleanroom and vacuum-compatible design practices, including materials selection, particle control, and high-purity fittings
• FMEA, DOE, and sensitivity analysis
• VBA or Python for data analysis

Responsibilities

• Independently design and develop mechanical systems and subsystems for MSP's wafer deposition systems and other semiconductor and aerosol products, integrating them with electrical, controls, and software designs; provide mechanical design support for MSP's Next Generation Impactor inhaler test systems.
• Design and manage large, complex system-level assemblies, including tool frames, enclosures, and service access, with a clean top-level assembly structure, defined interfaces, and accurate BOMs.
• Design aerosol and gas flow-path hardware, including particle generation and classification components, deposition chambers, flow and vacuum manifolds, filtration, and high-purity fittings.
• Perform engineering analysis, including tolerance stack-ups, structural/FEA, vibration, airflow and particle transport, and materials compatibility, and evaluate design alternatives for performance, manufacturability, serviceability, and cost.
• Plan and execute component, subsystem, and system-level tests and experiments, including DOE, to verify and validate designs; analyze data and document results.
• Translate customer and product requirements into mechanical specifications, and support customers on technical questions, qualification, and field issues.
• Create and release engineering documentation, including 3D models, drawings with GD&T, BOMs, specifications, ECOs, DFMEAs, and test reports, following MSP's ISO 9001 design and development process.
• Lead the mechanical portion of projects: estimate tasks and resources, own the mechanical schedule, identify and mitigate technical risks, lead design reviews, and provide work direction and mentoring to other engineers, designers, and technicians.
• Work with suppliers on machined, sheet-metal, welded, and high-purity components, including design-for-manufacturability input, first-article inspection, and resolution of supplier quality issues.
• Work with manufacturing, quality, service, sales, and marketing to release products to production, resolve production and field issues, and develop engineering best practices.
• Other duties as assigned.

Benefits

• Comprehensive medical, dental, and vision coverage.
• 401(k) with company match.
• Paid time off, paid holidays, and paid floating holidays.
• Life insurance, employee assistance program (EAP), and professional development opportunities.
