Mechanical Engineer

Within SSOE’s Advanced Technology division, we specialize in high‑tech facility 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.

SSOE is seeking a Mechanical Engineer to support complex cleanroom and advanced manufacturing facility projects from concept through startup. In this role, you will develop and coordinate mechanical system designs for HVAC, exhaust, chilled water, boiler, process utility, and wastewater systems that support high-performance manufacturing environments. You will perform design calculations, support equipment sizing and system layouts, and use AutoCAD and Revit to produce accurate documents aligned with project requirements.

You will collaborate closely with project managers, discipline leads, clients, contractors, and other engineering teams to resolve design challenges, manage changes, maintain quality, and support constructability, safety, and schedule goals throughout the project lifecycle.

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.

• Perform mechanical engineering design for cleanroom, fab, and advanced technology facilities, including HVAC, exhaust, chilled water, boiler, pump, and wastewater systems.
• Develop design calculations, equipment sizing, and system layouts for air handling units, VAV systems, chillers, boilers, pump hydraulics, exhaust ventilation, and process-related utilities.
• Perform detailed mechanical system calculations including load analysis, airflow modeling, equipment sizing, pump head curves, pressure drop, and energy consumption to optimize system performance and support design decisions.
• Prepare and coordinate mechanical drawings and models using AutoCAD and Revit, ensuring alignment with project standards, client requirements, and multidisciplinary design intent.
• Support system analysis and hydraulic modeling to evaluate pressure drop, flow balance, and equipment performance.
• Coordinate closely with architects, process engineers, electrical engineers, structural teams, and project managers to integrate mechanical systems into complex facility designs.
• Participate in design reviews, QA/QC checks, and interdisciplinary model coordination using Navisworks to identify clashes and support resolution before construction.
• Respond to RFIs, review submittals, and evaluate vendor data to confirm compliance with design intent, applicable codes, and project specifications.
• Conduct site walks, field investigations, and construction administration support to verify installation, resolve field conditions, and support change management (if applicable).
• Incorporate applicable codes, standards, and safety protocols…
