Senior Mechanical Engineer — Vacuum Pump Product Development (Scroll & Multistage Roots)

Primary Responsibilities

Product Leadership & Lifecycle

• Own pump subsystems from requirements through DV/PV, launch, and field support; drive schedules, risks, and milestones.
• Frame trade-offs (performance, cost, reliability) and make data-driven decisions; present design reviews to leadership.
• Capture know-how via standards, best practices, and invention disclosures/patent applications.

Core Pump Design

• Design rotors, stators/scrolls, shafts, seals, valves, housings, motor mounts, and acoustic/thermal covers in SolidWorks.
• Engineer running clearances, coating/finish specs, and tribological interfaces to balance efficiency and durability.
• Apply GD&T (ASME Y14.5) and tolerance stacks to ensure interchangeability and stable yields.

Analysis, Verification & Test

• Perform structural/thermal FEA, basic rotordynamic checks, and thermal expansion studies to protect critical gaps.
• Plan and execute DOEs, DVPRs, and life tests; instrument rigs for pressure, flow, temperature, vibration, and power.
• Lead root-cause analysis (DFMEA/8D), iterate designs, and lock parameters for production.

Manufacturing Enablement

• Collaborate with CNC, sheet metal, and molding suppliers; define critical-to-quality features and inspection methods (CMM, gaging).
• Create drawing packages, BOMs, assembly work instructions, and custom fixtures/tooling; manage revisions via PDM/ECO.
• Partner with supply chain on cost, yield, and lead-time improvements; support packaging/industrial design for brand fit.

Qualifications We’re Seeking

• Track Record: Production mechanical product development with ownership from concept to launch; vacuum pumps, compressors, turbomachinery, or high-speed rotating equipment strongly preferred.
• Design Tools: SolidWorks (advanced assemblies/drawings) and PDM; proficiency with tolerance stacks and GD&T.
• Analysis: Hands-on FEA (thermal/structural); familiarity with vibration/rotordynamics and thermal management.
• Manufacturing: CNC machining, coatings/finishes, balancing, CMM inspection; pragmatic DFM/DFA.
• Leadership: Mentors engineers, coordinates cross-functional teams, and communicates crisply to technical and executive audiences.

Education & Experience

• BS in ME (or related) + 12+ years product development; or
• MS in ME (or related) + 8+ years; or
• PhD in ME (or related) + 5+ years.
• =2 years leading specialized technologies or new-tech programs.

Beneficial Backgrounds

• Dry scroll, multistage Roots, turbomolecular pumps.
• Compressors (screw/scroll/Roots), HVAC refrigeration compressors.
• Automotive: transmissions, superchargers, turbochargers; high-speed e-motors.
• Gas turbines, small engines, rotary water pumps, aerospace mechanisms.
