Founding Product Manager

Lumen Energy is a modern solar broker for commercial real estate that helps turn building rooftops into revenue through clean energy transactions. The Founding Product Manager will establish the company’s product management practice, own the roadmap for its commercial solar and storage marketplace, conduct user research, and coordinate cross-functional teams from discovery through delivery.

Responsibilities:

• Own and evolve a prioritized product roadmap for Lumen’s commercial solar and storage marketplace, informed by real user feedback, business priorities, and clear success metrics
• Shape features from discovery through implementation-ready prototypes. They should be clear enough that engineers can build confidently without constant back-and-forth to resolve ambiguity
• Serve as the connective tissue between Engineering, Sales, Ops, and Leadership: synthesize competing inputs, drive toward aligned decisions, and keep the product work moving
• Define success metrics before features ship and track whether they actually move the needle after they do
• Run a continuous user research practice: talk to building owners, solar developers, and internal stakeholders on a regular cadence, and turn what you learn into product decisions and priorities

Requirements:

• 5+ years of product management experience in a high-growth or startup environment, with demonstrated ownership of end-to-end product cycles from discovery through delivery and measurement
• Fluency with AI-assisted product development workflows, using LLMs to accelerate prototyping, research synthesis, and spec writing
• Strong visual and UX sensibility, particularly since we don't have a dedicated designer
• Strong written communicator: can write prosed documents to convey business context and customer needs so that engineers and AI can build without constant clarification and ambiguity
• High agency and influence: A track record of owning and defending a product roadmap, including making hard prioritization calls when resources are constrained
• Business acumen: you can reason about trade-offs between user value, technical complexity, and commercial impact, and connect product decisions to business outcomes
• Strong user research chops: knows how to design and run customer interviews, synthesize qualitative findings, and translate them into product decisions and priorities
• US work authorization required. We are unable to sponsor H1B visas at this time
• Familiarity with two-sided marketplace dynamics
• Experience in commercial real estate, legal tech, or other complex transaction-based businesses
• Prior experience in a client-facing role such as customer success or sales
• Track record as the first or only PM at a company — you've built a PM practice from scratch rather than inherited a mature one
