Senior HVAC Engineer

About the role

BrainBox AI, part of Trane Technologies, combines artificial intelligence, cloud computing and HVAC expertise to create autonomous buildings. It is looking for a Senior HVAC Engineer in Montreal who bridges traditional HVAC engineering with smart building technology. The engineer assesses and interprets existing mechanical systems, supports the integration of the AI-driven control platform and works with software engineers and the global deployment team to deliver energy savings and improved occupant comfort.

Key responsibilities

• Develop and refine detailed sequences of operation that form the basis of optimization algorithms for facility mechanical systems
• Integrate advances in artificial intelligence into those sequences and consolidate them into a single coherent standard
• Collaborate with AI research, MLOps and algorithm teams to deliver production-ready solutions
• Review mechanical and control drawings, sequences and submittals, and conduct remote system reviews of equipment configuration and control readiness
• Analyze BAS trend data and system performance to validate assumptions, detect anomalies and benchmark behaviour before and after optimization
• Support functional performance test protocols and provide engineering insight into optimization algorithm design
• Debug and troubleshoot control logic and optimization algorithms with the software development team
• Test and validate algorithms through virtual simulations and real-world field trials
• Train operations teams on the logic, configuration and expected behaviour of the algorithm sequences
• Provide technical documentation and feedback to improve platform performance and integration workflows

Required profile

• 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 not required
• Proven experience in HVAC applied system design and/or commissioning
• Daily oral and written use of both French and English

Required skills

• Engineering principles: thermodynamics, psychrometrics, heat transfer, refrigeration cycles and building automation systems
• Mechanical system design and controls
• Building automation systems (BAS)
