Sr. Solutions Engineer

About the role

R-Zero is hiring a Senior Solutions Engineer to drive the technical pre-sales motion for our Physical AI solution - a portfolio of occupancy sensors and intelligence that unlocks meaningful HVAC energy reduction in commercial buildings. 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.

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, and implementation pathways that resonate with executive decision-makers.
• Sales partnership : Partner with Sales on opportunity strategy, multi-stakeholder navigation, and objection handling - especially around BMS write-access, IT/security review, and capex versus EaaS commercial models.
• Building qualification and scoping
• Building qualification : Use internal tooling and engineering judgment to assess buildings against the qualification criteria (AHU specs, OA strategy, BMS readiness, occupancy patterns, energy recovery, existing DCV).
• Scope of work development : Develop technical scopes, sensor counts, sequence-of-operation strategies, and integration approaches from mechanical drawings, BMS point lists, and trended data.
• Site surveys : Conduct remote and occasional in-person surveys to validate AHU configuration, BAS points, and field conditions.
• End-to-end ownership
• Pre-sales to handoff : Own the technical journey from first call through clean handoff to implementation, ensuring scope accuracy and customer expectations are aligned.
• Implementation support : Stay engaged through deployment as needed - supporting BMS integration questions, validation visits, and customer escalations.
• Expansion opportunities : Surface portfolio expansion opportunities post-deployment by validating performance and equipping Sales to upsell additional buildings.
• Team and tooling
• Tooling contribution : Provide structured feedback on R-Zero's internal Solutions Engineering tooling and propose process improvements.
• Cross-functional partnership : Partner with Product, Engineering, and Sales to channel field insights into roadmap priorities and competitive positioning.
• Knowledge sharing : Author and maintain technical collateral, qualification heuristics, and customer-facing FAQs that scale the team's capability.
• Required Qualifications
• Customer-facing pre-sales: 3+ years in a Solutions Engineering or Sales Engineering role with demonstrated success leading technical discov
