Mechanical Engineer – Building Systems & HVAC Performance {Bellevue / Redmond, WA} Commercial Buildings | HVAC Systems | BAS / BMS | Chiller Plants | Central Plant | Building Performance Role at a glance Role: Mechanical Engineer Location: Bellevue / Redmond, WA (Hybrid) Hybrid: Typically ~3 days on site Experience: 5-15 years of mechanical engineering experience Focus: Commercial HVAC systems, central plant infrastructure, and building performance Salary: $110k – $140k base + bonus Element Six is retained by a specialist engineering advisory firm supporting large-scale technology campuses and complex commercial building portfolios across North America. The company works directly with owners and operators to improve how HVAC and mechanical systems perform in operation. For mechanical engineers interested in applying their expertise beyond drawings and construction projects, this role offers the chance to work on real building performance, operational optimisation, and large-scale commercial environments. Why this role is worth a look Many mechanical engineers spend most of their careers designing systems they rarely see operate. This role focuses on how HVAC and mechanical systems perform once buildings are operational. Engineers work across active commercial buildings, analysing system performance, identifying inefficiencies, and helping clients plan improvements to HVAC infrastructure and building automation environments. Rather than working on a single large design project, engineers typically manage multiple initiatives across building portfolios and work closely with facilities teams and operators. What you will own Analyse HVAC and mechanical system performance across commercial buildings Identify system inefficiencies and opportunities for optimisation Review mechanical system designs and upgrade strategies Work with facilities teams, engineers, and contractors Deliver technical recommendations to improve building performance Manage multiple engineering initiatives across building portfolios What success looks like First 90 Days: Build familiarity with the building environments, systems, and engineering initiatives across the client portfolio. By 6 Months: Independently manage multiple engineering initiatives and deliver actionable recommendations to improve HVAC performance, efficiency, and operational reliability. Year One: Operate as a trusted engineering resource, helping clients improve building performance across their portfolios. Requirements We are looking for someone with: ~5–15 years of mechanical engineering experience ~ Experience working with commercial HVAC systems such as chiller plants, AHUs, chilled water systems, VAV systems, fan coils, or central plant infrastructure ~ Experience applying mechanical engineering in commercial office buildings, campuses, large facilities, or similarly complex environments ~ Experience in building automation systems and building controls environments ~ Strong communication skills and the ability to work directly with facilities teams and client stakeholders ~ A background in consulting engineering, building services engineering, commissioning, facilities engineering, or HVAC system optimisation ~ A Professional Engineer (PE) license is a plus, but not required If this sounds like work you have already done, reach out, and we can share more details about the client and projects involved.
