Sr. Solutions Engineer

R-Zero is hiring a Senior Solutions Engineer to drive the technical pre-sales motion for their Physical AI solution, a portfolio of occupancy sensors and intelligence that unlocks meaningful HVAC energy reduction in commercial buildings. The ideal candidate is a mechanical, controls, or energy engineer at heart who is energized by customer conversations and can hold their own in a technical discovery call, walk a CFO through energy savings logic, and spot the broken process they want to fix.

Requirements

• Customer-facing pre-sales: 3+ years in a Solutions Engineering or Sales Engineering role with demonstrated success leading technical discovery, delivering pitches and demos, and supporting enterprise sales cycles with multiple stakeholders.
• Technical depth: 5+ years of hands-on experience in HVAC system design, BMS/controls engineering, mechanical engineering, energy engineering, or building automation — with depth sufficient to read mechanical drawings and BMS point lists without supervision.
• Working knowledge of HVAC systems (AHUs, VAV, terminal units), BMS/BAS architectures, controls integration, and ventilation strategies.
• Experience working with internal AI/LLM-based qualification or scoping tools.
• Familiarity with ASHRAE 62.1, Title 24, and demand-controlled ventilation (DCV) approaches.
• Comfort reading mechanical drawings, BMS point lists, and trended controls data.
• Strong written and verbal communication — equally credible in front of a CFO, an energy manager, and a controls technician.
• Bachelor's degree in Mechanical Engineering, Building Science, Controls Engineering, Energy Engineering, or related field.

Benefits

• Generous time-off policies and paid holidays
• Competitive total compensation with equity
• Health benefits (medical, dental, vision) and 401(k) program starting on day one
