Staff Sales Solutions Engineer

About the Role

R-Zero is seeking a seasoned sales engineer to join our Solutions organization and drive the end-to-end technical success of our customers. This individual will lead and scale our pre-sales engineering function while also ensuring seamless handoff into implementation and ongoing customer expansion.

As the senior technical voice in the sales cycle, you will scope buildings for occupancy-based demand-controlled ventilation (ODCV) and other R-Zero solutions, working closely with Sales, Product, and Engineering to design offerings that are technically sound, scalable, and tailored to customer needs. Beyond scoping, you will own the customer journey through implementation with our Solutions team, ensuring that projects are delivered on-time, on-budget, and with high customer satisfaction.

The ideal candidate brings 8 or more years of expertise in HVAC systems, building controls, and BMS, and can translate complex engineering concepts into compelling, customer-facing solutions. Success in this role means not only equipping our sales team to win but also ensuring that every scoped project achieves successful adoption and creates a foundation for long-term customer growth.

Key Responsibilities

• Define and execute the Sales Engineering strategy within Solutions, creating scalable processes and tools that accelerate the sales cycle and improve conversion.
• Directly engage with customers alongside Sales Directors to assess buildings, analyze HVAC/BMS systems, and identify opportunities for occupancy-based DCV and other R-Zero solutions.
• Develop detailed scopes of work, technical designs, and ROI analyses that communicate business value and set the stage for successful implementation and expansion.
• Deliver and coach others to deliver high-impact demos of R-Zero’s platform, ROI tools, and M&V models — flexing between customer-facing execution and team enablement.
• Own the end-to-end technical journey from pre-sales through implementation, ensuring Solutions delivers projects on-time, on-budget, and with high customer satisfaction.
• Drive post-sales expansion opportunities by validating solution performance, surfacing growth needs, and equipping Sales to upsell and cross-sell additional offerings.
• Serve as the senior subject matter expert on HVAC controls, ventilation strategies, and IAQ standards, while also being hands-on in scoping and site work when needed.
• Conduct site surveys (remote and in-person) to capture and validate building data (AHU specs, BAS configuration, occupancy profiles, BMS points, trended data).
• Partner with Product, Engineering, and Solutions leadership to channel customer and field insights into product roadmap and future solution design.
• Create and maintain technical collateral, ROI tools, and training resources to enable scale and elevate team capability.
• Build, mentor, and lead a high-performing Sales Engineering team — acting as a player-coach while preparing the function for future scale.
• Measure and report on team impact, defining KPIs around scoping accuracy, sales enablement, implementation efficiency, and customer growth.
• Participate in customer deployments as needed, including onsite validation, system integration, and hands-on support (which may occasionally involve overnight work or physical tasks such as ladder work).

Qualifications

• 8+ years of experience in Sales Engineering, Solutions Engineering, HVAC systems design, building automation, or related fields.
• Proven success leading technical pre-sales and solutions engineering in a high-growth or startup environment, with the ability to both set strategy and execute.
• Deep knowledge of HVAC systems, building management systems (BMS), building automation, controls integration, smart building technologies, and energy modeling.
• Familiarity with indoor air quality standards and frameworks (ASHRAE, WELL, LEED) and demand-controlled ventilation (DCV) strategies.
• Demonstrated ability to translate technical detail into business value for customers — equally effective with executive decision-makers and technical teams.
• Experience supporting complex, enterprise sales cycles with multiple stakeholders, delivering scopes of work, ROI models, and solution designs that drive deal success.
• Strong collaboration and leadership skills, with experience mentoring or managing engineers in a growing team.
• Bachelor’s degree in Mechanical Engineering, Building Science, or related field (Master’s or PE license a plus).
• Nice to have: industry certifications such as LEED AP, WELL AP, CEM, or equivalent.

Travel Requirements

• Up to 20% travel may be expected as the businesses solutions scale and on-prem data capture requirements increase.

Why R-Zero

• Join a purpose-driven team tackling one of the biggest challenges facing the built environment- energy and carbon reduction.
• Work with innovative technologies at the intersection of health, energy, and smart building automation.
• Competitive compensation, equity, and benefits.
• A culture of collaboration, taking ownership, and innovation.
