About The Position

Budderfly is a fast-growth, private equity-backed energy management outsourcing company that is committed to reducing global carbon emissions for small to medium sized enterprises. We are the premier sustainability partner for businesses with repeatable footprints such as restaurant chains, assisted living facilities, retail franchises, and more. With zero upfront investment, Budderfly installs, monitors, and manages a combination of patented technologies, equipment upgrades, and proprietary energy software to help deliver complete energy saving solutions for our customers. Ranked #2 in energy companies and #10 overall on the 2021 Inc. 5000 America’s Fastest-Growing Private Companies list. We are an energetic and dedicated team working together to make a positive impact on the environment while providing an excellent customer experience. We are growing quickly and looking to add talented people who are passionate about making the world a better place! We are hiring a Senior Mechanical Engineer to join our Engineering team within Field Operations, reporting to an Engineering Manager as an individual contributor. Your primary focus is scaling our Ultra-High-Performanace, UHP program, our high performance HVAC and electrification offering built on VRF, heat pump and dedicated ventilation (ERV and DOAS) systems. You will develop and quality-check the designs and scopes of work behind UHP installs, set the standards that make them repeatable across site types, and support installation and commissioning. As the program matures, there will be opportunities to support controls, hydronic and other engineering needs across Field Operations. Depending on the project, your output may be a full design package, an engineering analysis, or a clear scope of work for a contractor to price and build from. You will work closely with teams across the company, including but not limited to IoT, Technology, Performance Analysis, Service, Project Management and Project Engagement.

Requirements

BS in Mechanical Engineering or a closely related field.

Ventilation design experience, including ERV or DOAS systems and air balance.
Experience supporting installation and commissioning.
Proficiency with load calculation and equipment selection software.
Working knowledge of ASHRAE 62.1 and 90.1, ASHRAE 15, and the International Mechanical Code.
Solid grounding in commercial HVAC fundamentals, including packaged rooftop units.
Familiarity with energy modeling or efficiency analysis, and with utility incentive programs and their documentation.
Clear written communication, and comfort explaining technical concepts to non-engineers and working across teams, contractors and manufacturers.
Comfort managing multiple priorities in a fast-paced, changing environment.

Nice To Haves

Working knowledge of BACnet and Modbus and building automation systems, and experience designing sequences of operation.
Experience with complex hydronic systems, including cooling towers.
PE license.
Experience with multi-site portfolios such as restaurant, hospitality, fitness, education or retail.

Responsibilities

Develop designs and scopes of work for UHP projects, including load calculations, ventilation and air balance, equipment selection and sizing, refrigerant piping and schedules.
Design ERV and DOAS ventilation systems for UHP sites.
Develop and maintain design standards for repeatable site types, so UHP can scale.
Perform technical QC review of UHP designs and scopes of work prepared by the wider team, and coordinate with third-party MEP firms when stamped documents are required.
Evaluate where VRF fits on payback and incentives, including where it can extend beyond the industry’s typical applications, and help refine our approach as UHP expands.
Support installation, commissioning and post-install troubleshooting with Project Management, field teams, Service, contractors and manufacturers.
Collaborate with IoT and Technology on controls requirements for UHP systems, and review OEM sequences of operation for the equipment we buy and inherit.
Engineer complex hydronic systems, including cooling towers, when needs arise.
Support other HVAC projects, such as packaged rooftop unit replacements, when UHP workload allows.
Prepare the engineering basis for energy savings calculations and utility incentive applications.
Help evolve our toolset toward load calculation and equipment selection software.
Collaborate regularly with IoT, Technology, Performance Analysis, Service, Project Management, Project Engagement and other teams.
Support the mentoring and growth of engineers across the team.
