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.
