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.

The Senior Mechanical Engineer leads mechanical design for complex cleanroom, fab, and advanced technology manufacturing facilities, shaping systems that support mission-critical operations, uptime, and safety. This role develops and coordinates HVAC and mechanical solutions from concept through construction and startup, including air handling units, VAV systems, chillers, boilers, exhaust ventilation, pump hydraulics, and wastewater discharge equipment. The engineer works closely with project managers, discipline leads, clients, contractors, and vendors to define scope, resolve technical issues, manage design changes, and support quality reviews.

Using AutoCAD, Revit, and Navisworks for modeling and clash detection, this role ensures technically sound, code-compliant, and constructible solutions while providing mentorship and technical leadership across project teams.

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.

• Lead mechanical design efforts for cleanroom, fab, and advanced technology projects from early planning and basis of design development through construction administration and startup support.
• Develop and review HVAC and mechanical system designs, including air handling units, HVAC ducting, exhaust, motor control, VAV systems, chillers, boilers, exhaust ventilation, pump hydraulics, wastewater discharge equipment and possibly other mechanical building systems.
• Perform and review design calculations, equipment sizing, pressure drop analyses, load calculations, and system coordination to support reliable, energy-conscious, and code-compliant solutions.
• Prepare and coordinate construction documents, specifications, and deliverables using AutoCAD and Revit, ensuring completeness, consistency, and alignment with project requirements.
• Participate in BIM coordination and model-based clash detection in Navisworks, resolving conflicts with architectural, structural, electrical, process, and utility systems.
• Interface directly with clients, contractors, vendors, and internal project teams to define scope, evaluate options, answer technical questions, and support decision-making throughout the project lifecycle.
• Lead technical discussions during design reviews, client meetings, and coordination sessions, translating operational and safety requirements into practical mechanical solutions.
• Review submittals, RFIs, change requests, and field conditions to evaluate impacts, recommend resolutions, and maintain design intent…
