ABOUT THE COALITION The Building Decarbonization Coalition (BDC) aligns critical stakeholders on a path to transform the nation’s buildings through clean energy, using policy, research, market development and public engagement. The BDC and its members are charting the course to eliminate fossil fuels in buildings to improve people’s health, cut climate and air pollution, prioritize high-road jobs, and ensure that our communities are more resilient to the impacts of climate change. The BDC is proud to be a leader in this conversation by organizing, engaging, and empowering a broad group of stakeholders united behind the common goal of eliminating fossil fuels from buildings. POSITION SUMMARY The demand for qualified contractors to install cold-climate heat pump technology is rising in Colorado. Increased incentives from public and private sources are encouraging end-users to invest in heat pump technology. The Colorado heating, ventilation, and air conditioning (HVAC) industry, consequently, has experienced an influx of services, resources, incentives and programs dedicated to guiding contractors and consumers through the growing landscape of resources. This expansion, however, also led to an overload of administrative requirements and disjointed resources, creating barriers to efficient adoption. To address these challenges, BDC created the Colorado Contractor Hub (in addition to other Contractor Hubs across the country) as part of a larger decarbonization initiative. The Contractor Hub is a streamlined resource for HVAC and home efficiency contractors to simplify the adoption of cold climate heat pump technology in their services. The Contractor Hub offers contractors a suite of free resources, provides a small business scaling program, and a training calendar. A team of “Contractor Agents” help contractors to navigate the Contractor Hub, rebate programs, and offer free tailored project management assistance to navigate the installation of cold-climate heat pump technologies (and related services). The Contractor Agents support contractors working in the rapidly growing cold-climate heat pump industry in Colorado. As front-line partners to our contractors, you’ll provide a wide range of specialized services, including, but not limited to, recruitment of contractors and marketing of the Hub, providing onboarding support, conduct AI model training for the Hub ChatBot, and guide contractors through rebate applications. The Contractor Engagement Agent will provide services that will include (but not be limited to): - Helping implement established program services aimed at recruiting, engaging, and retaining contractors, ensuring up to date information in the Contractor Hub’s customer platform (HubSpot); - Creating and collaborating to develop the Contractor Hub’s social media strategy and calendar for LinkedIn, Instagram, BlueSky, and other platforms as needed; - Helping design marketing and outreach materials, including graphics for Contractor Hub collateral, social media, and slide decks; and, - Socializing the Contractor Hub opportunity with key contractor stakeholder groups (e.g., meetings, in-person presentations, webinars, newsletter, etc.). The ideal candidate brings a blend of marketing expertise, technical knowledge, project management skills, and a customer service mindset. The Contractor Agent must be a self-starter with strong attention to detail, comfortable managing multiple contractor relationships at once, and adept at interpreting evolving incentive landscapes. The Contractor Engagement Agent will report to the Associate Director of Colorado Contractor Hub and collaborate with BDC teams such as the Project Management Office, Digital Products, Partnerships, and Finance. In addition, this role serves as a key go-between and source of truth for feedback on our tools, contractor engagement, and other areas, establishing a critical feedback loop. ESSENTIAL FUNCTIONS 1. Contractor Education - Socialize and deliver training and technical guidance on using the Contractor Hub and the Training Center, ensuring contractors can effectively navigate features, tools, and installation opportunities. - Develop and distribute educational and promotional materials focused on cold-climate heat pump systems, rebate eligibility, and financing options (e.g., newsletter, social media, and marketing materials). - Support contractors in identifying and accessing program opportunities, including available funding and incentives. 2. Contractor Engagement & Support - Provide responsive, hands-on support via email, chatbot, and phone to troubleshoot Contractor Hub enrollment issues and assist with rebate applications, and other inquiry tickets. - Offer guidance on training opportunities, industry trends, and approaches to remain competitive in the market. - Serve as a trusted advisor, walking contractors through complex processes such as application submissions and rebate collection. - Prioritize support for Small, Minority, Woman, and Disabled Veteran-owned (SMWDV) businesses when appropriate. 3. Project Management & Collaboration - Maintain comprehensive and up-to-date contractor records within customer relationship management system for accurate tracking and reporting (HubSpot). - Track key performance indicators, such as training reimbursements, AI Assistant utilization, and contractor satisfaction. - Work cross-functionally with BDC colleagues to provide insights and recommendations for our tools, using feedback loops and performance data. - Contribute to the preparation of reports and presentations for internal teams and external stakeholders.
