Senior Mechanical Engineer - Semiconductor Tool Installations

Uses vibe-coding platforms and industry LLMs as part of the workflow; AI tools are provided to boost productivity and streamline design tasks.

Lead mechanical design and systems engineering for semiconductor tool installation projects, owning end-to-end mechanical systems from utility matrices and UPW to HVAC and hazardous material exhaust. Serve as a technical leader and mentor, ensuring code compliance, cross-discipline coordination, and construction-phase support.

Senior Mechanical Engineer responsible for leading complex mechanical design efforts for semiconductor tool installation projects. The role includes system-level design, technical leadership, mentorship of junior engineers, cross-discipline coordination, and hands-on construction support, with access to AI tools and vibe-coding platforms to enhance productivity.

• Act as the mechanical authority on projects, set design direction, resolve technical conflicts, and ensure system integrity from concept through construction.
• Own end-to-end mechanical design for tool installations, including utility matrices, point-of-use (POU) connections (PCW, exhaust, specialty gases, chemical drains), and subfab/cleanroom modifications.
• Design and specify complex HVAC systems (AHUs, VAV, chillers, boilers, pump hydraulics, exhaust ventilation) and process utility systems (UPW/RO/DI, process cooling/heating).
• Design specialized exhaust, chemical delivery, and drain systems for hazardous production materials, ensuring compliance with ASME, ASHRAE, NFPA, SMACNA, and SEMI standards.
• Perform thermodynamic, hydraulic, and psychrometric analyses; develop sequences of operation and contribute to control system narratives.
• Validate designs against state/local codes and relevant standards (ASHRAE, NFPA 90A, SEMI), and apply computational/code-based validation methods.
• Drive coordination across electrical, structural, process, chemical, controls, and architectural teams; lead design reviews, HAZOPs, and constructability reviews.
• Provide construction support including RFI responses, submittal reviews, site inspections, field verifications, as-built documentation, and system start-up oversight.
• Develop and review project deliverables: drawings, specifications, calculations, and reports.
• Mentor junior engineers, contribute to internal standards, lessons-learned, and promote a safety-first design philosophy.

Required:

• Bachelor’s degree in Mechanical Engineering (ABET-accredited).
• Active Professional Engineer (PE) license in Arizona or eligibility to obtain by reciprocity within six months of hire; responsible charge and stamping authority required.
• 8+ years of progressive mechanical systems design experience for semiconductor, pharmaceutical, microelectronics, or other contamination-controlled manufacturing environments.
• Demonstrated expertise in HVAC and process utility systems design.
• Proficiency with AutoCAD for mechanical design.
• 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 and communicate technical information clearly to clients and project teams.
• Experience delivering mechanical design packages (drawings, specifications, calculations, reports) for complex industrial or high-tech facilities.

• Direct experience with semiconductor fab tool installation design (utility matrices, POU connections, HPM exhaust systems, UPW infrastructure).
• Experience leading HAZOP studies, constructability reviews, and design-phase risk assessments.
• Familiarity with SEMI standards (S2, S8, F15, etc.).
• Track record of mentoring junior engineers or leading small engineering…
