Phoenix, AZ

Posted: 06/30/2026 Industry: Engineering Job Number: 38101

Job Description

We have an immediate need for a Senior Mechanical Engineer in Phoenix, AZ. This is an onsite role and required to report to our office in the Northern Phoenix area.

Base salary range of ($130-$160K), relevant to experience and education.

Benefits: Includes comprehensive health, dental, and vision insurance, life insurance, 401K retirement savings plan (with company matching), opportunities for professional development and training (including support for relevant licensure & certifications), and generous PTO & paid holidays.

Job Summary:
You will collaborate daily with specialists across every discipline, contributing to some of the most capital-intensive and technically complex facilities on the planet. Your lead will play a central role in designing and delivering the mechanical groundwork that powers advanced semiconductor fabrication facilities.

Responsibilities:

A.  Technical Leadership & System Design
  • Serve as the mechanical authority on projects, by setting design direction, resolving technical conflicts, and ensuring system-level integrity from concept through construction.
  • Own end-to-end mechanical design of semiconductor tool installations, from utility matrices and point-of-use (POU) connections (PCW, exhaust, specialty gases, chemical drains) to specialized systems for contamination-controlled environments.
  • Lead the design, analysis, and specifications of complex HVAC systems, including air handling units, VAV systems, chillers, boilers, pump hydraulics, and exhaust ventilation, for advanced semiconductor fabrication facilities.
  • Engineer ultra-pure water (UPW/RO/DI) infrastructure and process cooling/heating systems that meet the stringent purity and reliability requirements of fab operations.
  • Design specialized exhaust and chemical delivery/drain systems for hazardous production materials (HPMs), championing a safety-first approach that meets or exceeds ASME, ASHRAE, NFPA, SMACNA, and SEMI standards.

B.  Analysis & Optimization
  • Perform detailed thermodynamic, hydraulic, and psychrometric analyses to optimize system performance, energy efficiency, and operational stability, directly influencing fab uptime and yield.
  • Develop sequences of operation (SOO) and contribute to control system narratives that ensure seamless integration of mechanical systems with facility controls architecture.
  • Apply computational and code-based methods to validate mechanical designs against applicable state/local codes, ASHRAE standards, NFPA 90A, and SEMI guidelines.

C.  Cross-Disciplinary Collaboration & Project Delivery
  • Drive coordination across electrical, structural, process, chemical, controls, and architectural teams to deliver fully integrated mechanical systems on complex, multi-discipline projects.
  • Lead and participate in design reviews, HAZOP studies, and constructability reviews, serving as the mechanical authority from concept through commissioning.
  • Translate tool vendor requirements into optimized utility matrices that reduce installation complexity and accelerate fab readiness.
  • Provide hands-on engineering support during construction: 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) ensuring technical accuracy, constructability, and code compliance.

D.  Mentorship & Technical Excellence
  • Shape the next generation of mechanical engineers by serving as a technical authority and mentor who raises the technical bar for the entire team.
  • Review and guide the work of junior engineers and designers, providing constructive feedback that builds capability and confidence.
  • Champion knowledge-sharing practices, contributing to internal standards, lessons-learned databases, and design guidelines that benefit the broader engineering organization.
  • Drive a safety-first design philosophy that protects people, processes, and the surrounding community on every project.

Required:
  • 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 are required for this position.
  • 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.
Preferred:
  • 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.
