Job summary

SSOE Group in Hillsboro, Oregon seeks a Senior Mechanical Engineer to lead design for cleanroom, fab, and advanced technology facilities, shaping HVAC and mechanical systems from concept through startup. You’ll collaborate with project managers, clients, and vendors, using AutoCAD, Revit, and Navisworks to deliver code-compliant, constructible solutions.

The role requires ABET-accredited Mechanical Engineering degree, PE license or license-by-ex reciprocity, and semiconductor/fab experience.

Qualifications

• Bachelor’s degree in Mechanical Engineering from an ABET-accredited institution.
• Active Professional Engineer (PE) license or evidence of ability to obtain by reciprocity within six months of hire; responsible charge of mechanical design and stamping authority required.
• Mechanical design experience in semiconductor, cleanroom, fab, or advanced technology manufacturing facilities, or other technically-related markets.
• Demonstrated proficiency with AutoCAD and Revit for mechanical design and BIM coordination, including Navisworks for clash detection and coordination.
• Proven ability to interface with clients and contractors to define scope, lead technical discussions, and support design execution through construction.
• Strong knowledge of QA/QC practices, constructability review, and construction administration processes including submittals, RFIs, and field coordination.
• Proven leadership, mentoring, and communication skills with the ability to guide junior staff and collaborate across multiple disciplines.
• Excellent written and verbal communication skills.

Responsibilities

• Lead mechanical design 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, 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 during construction.
• Support site walks, field observations, punch list development, and startup activities to verify installation quality, system readiness, and operational performance.
• Apply QA/QC practices to mechanical deliverables, identifying design risks, constructability concerns, code issues, and coordination gaps before issuance.
• Manage design changes and technical risk through organized communication, documentation, and timely coordination with project leadership and other disciplines.
• Mentor junior engineers and designers, providing technical guidance, reviewing work products, and promoting knowledge-sharing across the mechanical discipline and project teams.
• Support stamping and responsible charge activities for mechanical design packages in accordance with professional licensure requirements and company standards.
• Contribute to process improvement, lessons learned, and best practices that strengthen quality, efficiency, and consistency across projects.
