What is building systems engineering?

Building Systems Engineering is a multidisciplinary field focused on the design, integration, operation, and maintenance of a building’s essential systems, such as HVAC (heating, ventilation, and air conditioning), electrical, plumbing, and fire protection. Engineers in this field ensure that these systems work together efficiently to provide comfort, safety, sustainability, and functionality within buildings. They collaborate closely with architects and construction professionals to meet regulatory standards and optimize building performance. Building Systems Engineers play a key role in improving energy efficiency and supporting green building initiatives.

What are the key skills and qualifications needed to thrive as a building systems engineer?

To thrive as a Building Systems Engineer, you need a solid background in mechanical, electrical, or civil engineering, often supported by a relevant engineering degree and professional certification (such as PE or EIT). Familiarity with building automation systems, HVAC, AutoCAD, and energy management software is typically required. Strong problem-solving abilities, attention to detail, and effective communication skills enable you to collaborate with diverse stakeholders and ensure system reliability. These competencies are crucial for designing, maintaining, and optimizing safe, efficient building environments.

What are some common challenges faced by building systems engineers when working on retrofit projects in existing structures?

Building Systems Engineers often encounter unique challenges during retrofit projects, such as integrating modern systems with outdated infrastructure and ensuring compliance with current codes. Limited access to existing mechanical, electrical, or plumbing systems can complicate upgrades, requiring creative problem-solving and collaboration with architects and contractors. Additionally, balancing energy efficiency improvements with budget constraints and minimizing disruptions to occupants are key considerations that demand both technical expertise and strong communication skills.

What is the difference between Building Systems Engineering vs Mechanical Engineering?

AspectBuilding Systems EngineeringMechanical Engineering
CredentialsBachelor's in Engineering, PE license often preferredBachelor's in Mechanical Engineering, PE license common
Work EnvironmentDesigning and managing building systems like HVAC, plumbing, electricalDesigning mechanical devices, engines, manufacturing systems
Industry UsageConstruction, building design, facilities managementManufacturing, automotive, aerospace, energy

Building Systems Engineering focuses on designing and maintaining building infrastructure systems, while Mechanical Engineering covers a broader range of mechanical devices and systems across various industries. Both roles require similar credentials and often work within the construction and manufacturing sectors, but their specific applications differ significantly.

Are building systems engineers in high demand?

Building systems engineers are in high demand due to the need for efficient design, installation, and maintenance of building automation, HVAC, and electrical systems. The role requires technical skills, knowledge of industry standards, and often certifications, with employment opportunities growing as building complexity and sustainability efforts increase.

What does a building systems engineer do?

A building systems engineer designs, analyzes, and maintains the mechanical, electrical, plumbing, and control systems that ensure a building's safe, efficient, and reliable operation. They often use tools like CAD software and may hold certifications such as LEED or PE. Their work involves coordinating with architects and contractors throughout construction and maintenance phases.

Job description

About the Team:

The Systems Engineering team ensures that Terran R comes together as a cohesive, high-performing, and scalable system. Within the department, one team focuses on building tools and processes to manage requirements, track decisions, and identify and mitigate risk - enabling faster, more informed development across the program. Engineers work across domains to understand complex problems, identify solutions, and implement them - all with deep technical knowledge, not just documentation. The other team focuses on the vehicle itself, working across teams to ensure all subsystems of Terran R function together as intended, burning down technical risk, and driving informed decisions at every stage of the vehicle lifecycle. Engineers are empowered to lead high-impact efforts, from major test campaigns to console operations during launch, and are trusted to drive improvements across fluids, structures, avionics, and more. Regardless of which team you're on, you'll be part of a high-visibility, high-impact department at a pivotal moment in the program, where decisions made today on trades, architecture, and process will shape not just the first launch, but the long-term trajectory of Relativity.

About the Role:

  • Work closely with engineering leadership across the company ensuring the systems engineering tools and processes are enabling responsible engineers to move fast while also providing the right amount of engineering rigor to prevent downstream issues
  • Focus on creating and rolling out new processes while focusing on streamlining and eliminating processes that are no longer effective or does not scale with the ambitious launch ramp rate
  • Manage a team of engineers who are helping drive the existing Systems Engineering process while also focusing on reducing risk at the Subsystem and Component level as we step into Stage Testing
  • Look broadly at existing requirements to make sure verification actives are occurring at the right time and are burning down risk prior to stage testing
  • Ensure other test objectives are properly captured at the subsystem level and all affected parties are aligned on how the objectives will be met
  • Mentor team members and engineers in other departments while providing a second set of technical eyes ensuring processes are being leveraged to help burn down technical risk

About You:

  • Bachelors degree in Engineering or technical field
  • 5+ years of experience in technical positions working on system engineering, system definition, design, and development, system architecture, system integration, and/or T&E.
  • Full product lifecycle experience on at least one program, preferably two or more (from concept through production/operations)
  • Proven ability to work in a dynamic environment that includes working with changing needs and requirements.

Nice to haves but not required:  

  • Previous people leadership experience
