About Lumen Energy

Lumen Energy is the modern solar broker for the nation's largest commercial real estate owners. We partner with leading owners to turn underutilized rooftops into profitable solar revenue — delivering investment-grade analysis powered by our proprietary Lux Engine, securing transparent competition among top developers, and providing white-glove service throughout. Owners unlock predictable ancillary income, advance sustainability and resiliency goals, and scale solar across their portfolios without distraction from their core business.

We work with leading institutional CRE customers including Nuveen, KKR, and J.P. Morgan Asset Management, and we're backed by Lowercarbon Capital and Designer Fund. The team comes from Stripe, Google X, Arcadia, and Siemens, united by a mission to power the built world with profitable clean energy.

The role

We're looking for a B2B ABM Manager to own top-of-funnel: turn institutional CRE owner prospects in our target markets into booked meetings and engaged pipeline. Marketing operator first, manager second — build the playbook, run the plays, measure everything, then scale what's working.

You'll be the resident expert on our Ideal Customer Profile (ICP) — institutional commercial real estate owners — and the person accountable for filling the pipeline with qualified opportunities. You'll own the full funnel from first cold touch to qualified meeting, working closely with Sales to ensure alignment and impact.

What you'll own

• A quarterly target for qualified meetings booked and pipeline sourced into ICP accounts.

• Lumen's outbound engine, end-to-end, across multiple channels — list building, sequencing, copy, send, iterate. Cold calling included: define the scripts, make calls yourself, and set up AEs to make them as well.

• The campaign calendar — briefs, creative, audience targeting, launch, optimization, post-mortems.

• Account-Based Marketing programs for tier-1 institutional prospects — multi-channel, multi-touch, measurably tied to pipeline.

• The marketing tech stack — HubSpot ownership for campaign execution, lead scoring, attribution, and pipeline reporting; sequencer, enrichment, intent data, and ABM tooling.

• AI-assisted SDR (AISDR) programs — execute and optimize for scalable outreach where it can extend the team's reach without diluting message quality.

• The measurement stack — channel ROI, cost per meeting, cost per opportunity, conversion rates by stage and segment. A weekly scorecard everyone reads.

Where you'll be a critical collaborator

With Sales (Ops and AEs):
Run tight feedback loops on outbound campaigns, lead routing, handoff SLAs, meeting quality scoring, and message-market fit signal. Translate market insights and campaign learnings into actionable sales intelligence. Partner on sales enablement materials — marketing owns the artifact; you bring the messaging and the data.

With Marketing leadership:
Plan and execute multi-channel top-funnel programs across outbound email, LinkedIn, paid search and social, events and conferences, webinars, partnerships, content syndication, and ABM. Test relentlessly — new channels, new lists, new ICP cuts, new offers. Manage outside vendors, agencies, and contractors; bring work in-house when it's cheaper or better. Partner on positioning, ICP definition, and territory strategy as the funnel teaches us what resonates.

Who you are

• ~5–7 years in B2B growth, lead gen, GTM, ABM, or sales development — with a steep trajectory and a track record of doing more each year.

• Marketing operator first: you write the email, build the list, set up the sequence, run the ads, pull the report. Manager second: you can hire, brief, and direct help once volume demands it.

• Comfortable selling to sophisticated institutional buyers — long sales cycles, multiple stakeholders, complex products. CRE, climate tech, proptech, financial services, or B2B SaaS backgrounds are most relevant.

• Numbers-native: lives in a dashboard, makes decisions from data, can build the dashboard if it doesn't exist.

• Expert-level proficiency with HubSpot or a comparable marketing automation platform; familiarity with AI-powered SDR tools and modern outbound stacks.

• Strong written instinct — outbound copy, ad copy, landing pages, sales enablement.

• High agency: figures out what to do when no one tells you, ships before it's perfect, owns outcomes.

• Scrappy with a budget; rigorous with attribution.

Nice to have

• Deep knowledge of commercial real estate, particularly institutional owners and operators.

• Experience standing up an ABM program from scratch in an early-stage or high-growth environment.

• Background in cold calling and outbound sales development as well as marketing.

• Working knowledge of Hubspot, data enrichment tools, and attribution platforms.

Compensation & Benefits

Salary Range: $110,000 - $145,000 base salary; variable performance-based bonus

Final compensation will be determined based on experience, skills, and geographic location

Benefits include:

• Comprehensive health, dental, and vision insurance

• 401(k) plan

• Flexible PTO

• Remote work flexibility

• Professional development budget

• Equipment and home office stipend

• Mission-driven work accelerating the clean energy transition

How to apply

Send a resume and a brief note about why you're excited about this role. We're especially interested in:

• An ABM or demand-gen program you've built from scratch and the pipeline impact it produced

• Your experience with commercial real estate or a similarly complex B2B sale

• A campaign you ran that moved the needle, and what you learned from one that didn't

• How you think about marketing technology and the right level of investment for the stage

Lumen Energy is an equal opportunity employer. We celebrate diverse perspectives and are committed to building an inclusive workplace. US work authorization required. We are unable to sponsor H1B visas at this time.

About Lumen Energy

The team comes from Stripe, Google X, Arcadia, and Siemens, united by a mission to power the built world with profitable clean energy.

The Role

We're looking for a Product Engineer who lives at the intersection of product and engineering. This is a high-impact role: you'll wear both product and engineering hats, driving features end-to-end from idea, through rapid prototyping, to polished production experiences. You'll shape what we build and why, not just how.

You'll report directly to our Head of Engineering and work cross-functionally with our entire team. This is a full-time, remote (US) role, with an SF office if you'd like one.

What You'll Do

• Drive product iteration and execution. Work with partners across Marketing, Sales, and Operations to identify product gaps, then carry solutions through conception, implementation, and maintenance

• Prototype rapidly with AI tools. Get tangible, testable experiences in front of customers and teammates early, and use their feedback to decide what deserves further investment

• Build and ship features end to end, from early prototype through production-ready code

Who You Are

• A prototyper, not just a builder. You get your work into people's hands and collect feedback. When a prototype is dead in the water, you say so and move on without getting attached. You are not precious about the things you build.

• An empathetic communicator. You express nuanced ideas clearly for different audiences, give and take direct feedback well, and prioritize curiosity over confrontation in disagreements

• A designer at heart. You hold a high bar for polished user experiences, catch quality issues others miss, and don't need pixel-perfect specs to know when something's off

• High ownership, low drama. When a problem is underspecified, you ask sharp questions, make reasonable assumptions, and keep moving. You follow through, flag blockers early, and close loops

• Motivated by mission. You want your work to advance the energy transition

Qualifications

Required:

• Proven track record of execution. You have 3–5+ years of experience in a product engineering, frontend, full-stack, or design engineering role

• Enough production experience to have real opinions about frontend architecture and tooling — you've seen good and bad in the wild and can tell the difference.

• Familiarity with our tech stack (or strong ability to learn new technologies quickly). Our current tech stack is Python, Flask, SQLAlchemy, PostgreSQL, Rust, TypeScript, React, GraphQL, Google Cloud Platform (See more about the code at the end of this posting)

• Demonstrated use of AI coding tools (Cursor, Claude, Codex, etc.) as a core part of your development workflow

Nice to Have:

• Experience in a startup or high-growth environment

• Background or genuine interest in climate tech or real estate

Who this role isn't for

We'd rather you know now than three interviews in:

• You want a large, specialized team. If you're looking for a big frontend guild, dedicated design systems teams, full-time product managers and designers, you’ll be disappointed. We all wear multiple hats.

• You prefer deep backend work. This role leans frontend. If you're a backend engineer who tolerates UI work rather than enjoying it, the day-to-day will feel misaligned.

• You want process and predictability. Early-stage startups have shifting priorities, incomplete specs, and decisions made in slack threads. If you need a well-oiled sprint machine, this will be frustrating.

About the interview

• Round 1 (45 minutes): Introduction call with Kerri Devine (Head of Engineering)

• Round 2 (45 minutes): Cross-functional product sense discussion

• Round 3 (120 minutes): Technical evaluation with engineering team

  • Architecture design review

  • AI coding collaboration exercise

• We may request subsequent interviews here if we didn’t get enough signal in a particular competency.

• (Optional): You’re welcome to have conversation(s) with your cross-functional peers to interview us.

About the code

• We use Python with Flask+SQLAlchemy on the backend.

• We use TypeScript with React on the frontend.

• We wrote a few Rust modules for where performance matters.

  • Utility tariff rate calculations

  • Spreadsheet calculations: we wrote an Excel interpreter so that we can express financial calculations in the format our users understand.

• We use advanced tools to help us develop, but default to choosing boring technology to run our site. So far Postgres does a great job with just about everything we need to do.

• We rely on machines for automating type checks and deploys.

  • We use auto-formatters, and our Python code is just about fully type-annotated.

  • We use immutable data classes wherever possible.

  • Code changes are deployed automatically when tests pass. About 30% of our python code is tests.

• We believe that getting the data model right will let the rest of the code flow easily. We’ve rarely gotten the data model right the first time.

Why Lumen

• Work that matters. Every rooftop we convert accelerates decarbonization at scale

• High ownership, early on. You'll have real impact from day one, not years from now

• A team that moves fast and values clear thinking over politics or hierarchy

• Competitive salary, benefits, and equity participation

• A culture that embraces technology, including AI. We use new tools actively and encourage you to do the same

• Room to grow. We promote from within and invest in the development of our team
