Senior Mechanical Engineer

Job Description

We are hiring for a Senior P.E. Mechanical Engineer in Austin, TX.

This is a hybrid on-site role and required to report to our office at least 3 days a week.

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 TX or eligibility to obtain by reciprocity within six months of hire. Responsible charge and mechanical design stamping authority are required for this position.
• 8+ 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.
