Position Overview

Are you a high-caliber engineer ready to transition from drafting systems to architecting the mechanical future of the Pacific Northwest? We are seeking a Senior Mechanical Engineer to serve as a technical linchpin within our premier design-build division. In this role, you aren't just calculating loads; you are a strategic lead, responsible for the lifecycle of sophisticated HVAC systems that power the region’s most critical infrastructures—from sterile healthcare environments to high-rise commercial towers.

Joining our team means stepping into an elite, integrated platform where the traditional friction between engineering and construction is eliminated. We offer a legacy-building opportunity where your designs are realized in real-time by our in-house construction and commissioning teams. This is a high-impact role designed for a visionary professional who thrives on technical autonomy, mentorship, and the drive to deliver sustainable, award-winning mechanical solutions.

Core Responsibilities

• System Architecture & Design: Lead the high-level design and engineering of complex HVAC systems, ensuring every solution is optimized for energy efficiency, code compliance, and client-specific operational needs.

• Design-Build Integration: Collaborate seamlessly with the pre-construction and field teams to bridge the gap between conceptual engineering and physical installation, ensuring a "one-stop" high-quality delivery.

• Technical Stewardship: Oversee the production of rigorous engineering calculations, detailed construction documents, and high-fidelity technical specifications.

• Leadership & Mentorship: Steer the professional development of junior engineers, providing the technical oversight and career coaching necessary to maintain the firm’s standard of excellence.

• Stakeholder Management: Act as the primary technical interface for clients, contractors, and multidisciplinary partners, translating complex mechanical concepts into actionable project milestones.

• Innovation & R&D: Evaluate and integrate emerging technologies and sustainable industry trends to continuously sharpen the firm’s competitive edge and service offerings.

• Project Oversight: Manage multiple high-priority projects simultaneously, maintaining an uncompromising standard of quality from initial feasibility through to final commissioning.

Required Qualifications

• Education: Bachelor of Science in Mechanical Engineering (BSME) from an ABET-accredited institution.

• Licensure: Active Professional Engineer (PE) License is mandatory.

• Experience: 7–10 years of progressive experience in HVAC design within the AEC industry.

• Software Proficiency: Expert command of Revit MEP, AutoCAD, and industry-standard load calculation software (e.g., Trace 700, HAP).

• Technical Mastery: Deep knowledge of IBC, IMC, and ASHRAE standards, with a proven track record of delivering successful projects in the commercial or industrial sectors.

Preferred Qualifications

• Sector Expertise: Specialized experience in OSHPD/Healthcare requirements or high-tech manufacturing cleanrooms.

• Sustainable Design: LEED AP credential or experience with Net Zero energy modeling.

• Regional Knowledge: Established familiarity with Oregon and Washington building codes and energy jurisdictions.

• Strategic Vision: Previous experience in a lead or principal-track role within a design-build environment.
