Do you dare to look at the world's challenges and see impactful possibilities? Do you want to contribute to making a better future? If the answer is yes, we invite you to consider joining us in boldly challenging what's possible for a sustainable world. Learn about our benefits designed for you to Thrive at work and at home. We boldly go.

Where is the work: Our BrainBox AI Workplace Presence model dedicates specific in-office days each month to focus on relationships, learning and innovation. What's in it for you: At BrainBox AI, we are revolutionizing how buildings consume energy by combining artificial intelligence, cloud computing, and HVAC expertise to create truly autonomous buildings. We’re looking for a Mechanical Engineer who brings deep knowledge of HVAC system design, commissioning, and field implementation — someone who understands how buildings operate in the real world and is excited to help optimize them through cutting‑edge AI solutions. In this role, you’ll bridge the gap between traditional HVAC engineering and next‑generation smart building technology. You will assess and interpret existing mechanical systems, support the integration of our AI‑driven control platform, and collaborate closely with software engineers and our global deployment team to deliver measurable energy savings and improved occupant comfort.

What you will do:

• Leverage HVAC system expertise to develop and refine detailed sequences of operation that serve as the foundation for optimization algorithms for facility mechanical systems.
• Integrate the latest advances in artificial intelligence into our sequences of operation, and consolidate them into a single coherent standard.
• Collaborate across AI research, MLOps, and algorithm teams to deliver production‑ready solutions.
• Review mechanical and control drawings, sequences, and submittals to understand system capabilities and identify opportunities for optimization.
• Conduct remote system reviews to evaluate mechanical equipment configuration and control readiness.
• Analyze BAS trend data and system performance to validate assumptions, detect anomalies, and benchmark system behavior before and after optimization.
• Support the creation of functional performance tests protocols to verify system operation and energy outcomes.
• Collaborate closely with software developers and system architects to translate mechanical principles into algorithms and control logic that improve building performance.
• Provide engineering insight into optimization algorithm design, ensuring alignment between physical system behavior and digital models.
• Support the debugging and troubleshooting of control logic and optimization algorithms, working hand‑in‑hand with the software development team to identify root causes and implement effective solutions.
• Conduct testing and validation of algorithms through both virtual simulations and real‑world field trials to verify functionality, energy savings, comfort, and operational reliability.
• Develop and deliver training sessions for operations team, explaining the logic, configuration, and expected behavior of the algorithm sequences.
• Provide technical documentation and feedback to improve platform performance, user experience, and integration workflows.
• Stay current on emerging HVAC, controls, and building automation technologies to continuously enhance BrainBox AI’s optimization capabilities.

What you will bring:

• 5-10 years of relevant experience in HVAC Engineering
• Bachelor's degree in Mechanical Engineering from an accredited program.
• Active Professional Engineer (P.E.) license – preferred but no required Deep understanding of engineering principles (Thermodynamics, Psychrometrics, Heat Transfer, Refrigeration Cycles, and Building Automation Systems)
• Proven and meaningful experience in HVAC applied system design and/or commissioning.
• Strong technical understanding of mechanical system design and controls.
• Demonstrated record of stable and successful employment history.
