This is a customer-facing, sales-forward role that pairs strong communication skills with mechanical engineering judgment. You'll be the technical voice in early-stage customer conversations, leading pitches alongside Sales Directors, qualifying buildings against R-Zero's occupancy-based demand-controlled ventilation criteria, and translating HVAC, BMS, and controls complexity into clear, compelling value for executive and engineering audiences alike. This is a startup role, and we mean it. R-Zero is a fast-moving company building a category that doesn't have a textbook playbook yet — which means the right person here gets to help write it. You won't just execute against an established pre-sales motion; you'll own the evolution of the tools, qualification frameworks, and processes the Solutions team runs on.  You'll operate as a senior pre-sales engineer on the Solutions team, partnering closely with the rest of the team to scale qualification velocity and feed a growing sales pipeline. You'll get hands-on with our internal tools, scope buildings from drawings and BMS data, and develop ROI narratives that move deals forward. The ideal candidate is a mechanical, controls, or energy engineer at heart who is energized by customer conversations — someone who can hold their own in a technical discovery call, walk a CFO through energy savings logic, turn a stack of mechanical drawings into a qualified opportunity by end of day, and spot the broken process they want to fix while they're at it. Key Responsibilities Customer-facing pre-sales Lead technical discovery: Run discovery calls with facilities directors, energy managers, and BMS controls staff to capture HVAC system architecture, BMS configuration, occupancy profiles, and existing DCV strategies. Pitch and demo: Co-pitch with Sales Directors and deliver high-impact demos of R-Zero’s occupancy based DCV platform, savings models, and M&V approach — flexing message and depth based on audience. Translate to business value: Convert HVAC and controls detail into ROI narratives, energy savings ranges, an...
