Building Commissioning Jobs in Seattle, WA (NOW HIRING)

About the Opportunity 

Start Date: September 1st, 2026

Length of Fellowship: 10 months

Location Type: Hybrid

Launch your career in sustainable building systems by improving building performance for people and the planet. As a Building Commissioning Fellow in the Climate Corps Fellowship program, you'll have the opportunity to contribute to impactful sustainability initiatives with McKinstry. This is a hybrid position with the expectation of onsite work 3-4 days per week.

During the fellowship, you'll work alongside experienced commissioning engineers on building systems projects across new construction and existing buildings. Building commissioning is a systematic quality assurance process that verifies a building's mechanical, electrical, plumbing, lighting, and controls systems are installed correctly and operating as designed - meeting energy code requirements and delivering the comfort and performance occupants expect. After installation and prior to delivery to the owner, the commissioning team verifies proper system behavior and resolves any deficiencies through installation verification, controls point-to-point checkout, and functional performance testing. This work is led by an independent commissioning agent who documents findings and works with the project team to ensure the building performs the way it was designed to from day one.

Fellows who successfully complete the program will be well-positioned for career pathways in commissioning engineering, including roles at the Commissioning Specialist level. This fellowship is designed for early-career candidates building toward a professional role in commissioning, building systems, or sustainable facilities management. This position offers a unique opportunity to develop your professional skills, grow your network, and contribute to McKinstry's sustainability goals.

What You'll Do

• Supporting pre-functional and functional test development, witnessing, and documentation for mechanical, electrical, and controls systems.
• Assisting with review of construction documents, submittals, and equipment schedules so that the proposed implementation will meet the overall design and performance needs of the project.
• Contributing to the investigation of the building's performance by tracking and logging performance observations, supporting issue resolution, and ensuring that the construction-phase meets all requirements.
• Supporting development of commissioning plans, schedules, and site-specific reporting.
• Participating in field verification activities - equipment identification, installation checks, and startup witnessing.
• Assisting with existing building investigations, including Building Automation Systems (BAS) trend data review and identification of operational deficiencies.
• Supporting turnover documentation, including Operations & Maintenance materials, systems manuals, and owner training coordination.

• A fixed, monthly stipend of $4500.
• $1000 end-of-program financial award.

What We're Looking For

• A background in mechanical, electrical, or architectural engineering, energy management, facilities, or a related field (degree, certificate, or equivalent experience).
• Basic familiarity with HVAC concepts and/or building automation systems - or demonstrated ability to learn quickly in technical environments.
• Comfort reading, or a willingness to learn to read, construction documents (drawings, schedules, submittals).
• Strong written and verbal communication skills - commissioning work is documentation-heavy.
• Proficiency in Microsoft Office (Word, Excel); experience with BAS platforms a plus.

• Reliable personal transportation for varied site visits is required.
• The ability to work onsite on a hybrid basis. Only candidates currently residing within commuting distance of the site address will be considered.
• Commitment to a fair workplace that honors the experiences, voices, viewpoints, and values of all individuals.
