Senior Mechanical Engineer
$130,000–$160,000 year
On-sitePhoenix, Arizona, United States
Job Summary
Lead end-to-end mechanical design for semiconductor tool installations, setting design direction and resolving technical conflicts from concept through construction. Own utility matrices, point-of-use connections, and specialized systems for contamination-controlled environments, including complex HVAC, ultra-pure water infrastructure, and hazardous material exhaust. Perform thermodynamic and hydraulic analyses to optimize system performance while driving cross-disciplinary coordination with electrical, structural, and process teams. Lead design reviews, HAZOP studies, and constructability assessments, providing hands-on support during construction via RFI responses, submittal reviews, and site inspections. Mentor junior engineers and champion safety-first design philosophies aligned with ASHRAE, NFPA, and SEMI standards.
Required Qualifications
- Bachelor's degree in Mechanical Engineering from an ABET-accredited institution
- Active Professional Engineer (PE) license in Arizona or eligibility to obtain by reciprocity within six months of hire
- Responsible charge and mechanical design stamping authority
- 6+ years of progressive experience in mechanical systems design for semiconductor, pharmaceutical, microelectronics, or other contamination-controlled manufacturing environments
- Demonstrated expertise in HVAC system design (AHUs, VAV, chillers, boilers, pump hydraulics, exhaust ventilation) and process utility systems
- Proficiency with AutoCAD for mechanical design
- Comprehensive working knowledge of ASHRAE standards, NFPA 90A, IMC/IBC, and applicable Arizona state and local mechanical and fire codes
- Proven ability to lead multi-discipline coordination efforts and communicate complex technical information clearly to clients, project managers, contractors, and cross-discipline engineering teams
- Experience in delivering mechanical design packages, that include drawings, specifications, calculations, and reports for complex industrial or high-tech facility projects
- Must be available onsite at the N. Phoenix, AZ facility (remote or hybrid work arrangements are not available)
Desired Qualifications
- Direct experience with semiconductor fab tool installation design: utility matrices, POU connections, HPM exhaust systems, and ultra-pure water infrastructure
- Experience leading HAZOP studies, constructability reviews, and design-phase risk assessments
- Familiarity with SEMI standards (S2, S8, F15, and related) governing semiconductor equipment safety
- Track record of mentoring junior engineers or formally leading small project engineering teams through complex mechanical design challenges
