Type:
Full Time

Within SSOE's Tool Install division, we specialize in high-tech Tool Installation design, offering top-tier design and engineering services to a diverse array of clients and markets. Our team is composed of highly skilled and knowledgeable professionals who excel across various disciplines. We pride ourselves on our cross-disciplinary approach, which allows us to understand and address our clients' needs more comprehensively than traditional, siloed methods.

What sets us apart is our ability to seamlessly conceptualize, plan, and detail every aspect of design. Our in-house experts collaborate closely, optimizing and enhancing our work through multi-discipline strategy sessions. By leveraging cutting-edge techniques and state-of-the-art software, we deliver industry-leading technology and innovative solutions from day one.

We are seeking to hire a Senior Mechanical Engineer to support our growing team. 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.

This role is based on our client's N. Phoenix, AZ facility, where you will work alongside our integrated engineering team onsite each day and collaborate in real-time on projects that benefit from hands-on coordination. Remote or hybrid work arrangements for this role are not available.

At SSOE, we don't just talk about the future, we build it. As a leader in industry AI adoption, we empower our team to work smarter by providing responsible access to the industry leading AI Large Language Models, vibe-coding platforms, and securely integrating advanced tools into every role. From day one, you'll receive the training and support needed to leverage AI as a core tool for enhancing productivity, sparking creativity, and streamlining complex workflows.

• 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.

• 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.

• 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…
