About the Role
Sunstone is seeking a Business Development Associate to join our team. Sunstone's partners are solar installers and developers selling solar systems to and installing solar systems for businesses. You will play a key role in expanding Sunstone’s commercial impact by owning and developing a portfolio of partner accounts. Your focus will be to deepen relationships, drive product adoption, and uncover new opportunities for mutual growth.
This role is ideal for a self-starter who thrives in ambiguity and is motivated to improve what exists rather than accept the status quo. You’ll bring a high level of ownership to your accounts, balancing strategic thinking with day-to-day execution. Success in this role requires hyper-responsiveness, exceptional organization, curiosity, and resilience.
You can expect significant autonomy in a fast-moving, evolving industry, with the opportunity to shape both your role and our partner strategy as Sunstone grows. Join us in building an agile, partner-focused, values-driven company.
Key Responsibilities:
- Account Management:
- Manage a high volume of simultaneous deals at various stages, maintaining accuracy and urgency across all of them — tracking every commitment, deadline, and follow-up.
- Juggle competing priorities across dozens of active accounts daily, knowing when to escalate and when to execute independently.
- Develop a deep understanding of each account's structure, priorities, and business objectives by asking thoughtful, sometimes challenging questions and probing beyond surface-level needs.
- Proactively engage partners to ensure a seamless experience for new loan applications, coordinating with internal cross-functional teams to support the successful execution of Sunstone-approved projects.
- Build and maintain strong, trust-based relationships with key stakeholders across each account.
- Serve as the primary point of contact — ensuring questions and issues are addressed accurately and quickly via email, phone, or text (Sunstone number provided).
- Account Development:
- Identify opportunities for account expansion and increased product adoption, partnering closely with director-level BD team members to develop and execute growth strategies.
- Leverage Sunstone's thought leadership — including webinars, best practices, and market insights — to deepen engagement with both new and existing partner contacts.
Qualifications
- At least two years of professional experience in a B2B customer-facing role. Finance or solar background preferred but not required.
- Proven ability to thrive in high-volume environments — you get energized, not overwhelmed, when the inbox is full and the phone won't stop.
- Exceptional attention to detail even when moving fast — you catch the typo in the term sheet and the missed callback on a busy Friday.
- Driven, resilient, and goal-focused. Unafraid to spend significant time calling, researching, and managing a large portfolio of accounts simultaneously.
- Engaging, confident, and energetic, with the ability to create rapport and inspire action quickly.
- Highly organized and responsive, committed to providing a great experience for partners while representing Sunstone.
- Strong written and verbal communication skills — able to convey professionalism, personality, and brand identity via phone, email, and text.
