We seek colleagues who are passionate about making real change in the built environment, excited to work at the leading edge of energy and real estate, and want to contribute to a high-performing team. Join us on our mission to profitably decarbonize buildings.

We’re seeking a Founding Product Manager to join our technology team. This high-impact, high-visibility role is perfect for someone who thrives on building from scratch: someone who can create structure where there isn’t any, build conviction with incomplete information, and operate as a partner to our internal team and customers.

You’ll be Lumen’s first dedicated PM, which means you won’t be inheriting a mature roadmap, an existing research practice, or a PM org to plug into. You’ll be defining what product management looks like here, with the autonomy, access, and trust to do it.

You’ll report directly to our Head of Engineering and work cross-functionally with Engineering, Sales, and Marketplace Operations to deliver an exceptional clean energy transaction experience for building owners and solar+battery developers alike.

• 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.

• Outcome-oriented, not output-oriented. You treat “I shipped the feature” and “the feature worked” as very different things, and you hold yourself accountable to the latter.

• High agency, at home within ambiguity. You don’t wait for someone to hand you a process or a brief. The absence of a playbook energizes you. You build conviction from incomplete information and make the call.

• Generative, then decisive. You’re the person who can brainstorm five wild ideas, and then pick the one that’s actually shippable. You’d rather make a strong call now than wait for perfection, but you know when to push for more input and when to trust your gut.

• Opinionated out loud. You form a view on what we should build and why, and you put it on the table, including when it’s unpopular. When someone shows you better information, you change your mind fast. Once a call is made, you carry it like it was yours.

• Collaborative and influential. You make complex trade-offs legible to engineers, ops, and leadership, and you get people aligned without grinding everything to a halt or burning bridges.

• A strong writer. You translate between audiences. The same decision gets explained to an engineer, an ops lead, and a CRE owner, and each version is accurate, and none of them are padded. We work async, so writing is how the thinking gets transmitted, not a report you produce after the thinking is done.

• An eager adopter of new technology. You’re excited about AI tools and actively curious about what the PM role looks like when teams can build ten times faster.

• A genuine researcher. You find customer conversations energizing rather than a chore, and you know how to turn qualitative signal into clear product decisions.

• Motivated by mission. You care about clean energy, and you want the work to
