Mechanical Systems Engineer – Complex and Decarbonized Buildings

Role Overview

• Lead and support the design of advanced HVAC and thermal systems for buildings with high operational, reliability, and performance requirements.
• Develop system concepts, calculations, and design strategies that address redundancy, maintainability, and life cycle outcomes, not just code compliance.
• Solve non-standard engineering problems where precedent solutions may not apply.
• Apply sound engineering judgment to evaluate competing system approaches and tradeoffs.
• Support projects involving central plants, shared mechanical systems, or campus scale infrastructure when applicable.
• Evaluate system strategies such as central heating and cooling plants, heat recovery, thermal energy storage, and large-scale electrification.
• Integrate decarbonization goals into mechanical system design, including electrification, efficiency improvements, and low carbon system selection.
• Collaborate with sustainability and building science teams to align mechanical strategies with energy and emissions performance targets.
• Support early stage analysis to help clients understand technical and operational implications of decarbonization pathways.
• Work closely with architects, electrical engineers, and other disciplines to develop coordinated, technically sound designs.
• Contribute to technical narratives and client deliverables that clearly explain system rationale and performance implications.
• Communicate complex engineering concepts in a clear, practical manner to both technical and non-technical stakeholders.
• Stay current with evolving technologies, codes, and best practices related to complex mechanical systems and building decarbonization.
• Contribute to internal standards, tools, and knowledge development as BranchPattern advances its energy and systems expertise.
• Mentor junior engineers and support a culture of technical rigor and curiosity.

Requirements

• Licensed Professional Engineer (PE), or ability to obtain licensure
• 5+ years of experience designing and analyzing complex mechanical systems for buildings
• Bachelor’s degree in Mechanical Engineering or Architectural Engineering
• Experience with technically demanding facilities such as healthcare, laboratories, or other mission critical environments
• Strong interest in decarbonization, system efficiency, and performance driven design.
