Position Overview

This position reports to the CEO and sits alongside Greentown's Growth function. Greentown Labs is hiring a Head of Development to own and drive philanthropic and partnership revenue across the organization, carrying a multi-million-dollar target and building the pipeline and relationships to sustain and grow it.

This is development reimagined for the climate era: a modern, entrepreneurial capital-mobilization mandate, not a traditional back-office development function. Its center of gravity is national major gifts and growth capital, roughly three-quarters of the role, with a meaningful secondary focus on enabling structured annual giving and sponsorship at the Boston and Houston sites. To start, this is a team of one in direct partnership with the CEO, with the potential to grow into a larger development function over time; cross-functional support comes from site leadership, the Chief of Staff, and the CEO. You will be as comfortable with a climate philanthropist as with an energy investor or a legacy energy company, and you do not pick camps.

What you'll do

Pillar 1 — Major Gifts and Growth Capital (primary focus, ~75%)

Carry a multi-million-dollar annual revenue target and personally lead the cultivation, solicitation, and closing of gifts from $50K to $500K and well beyond
Cultivate high-net-worth individuals, family offices, climate philanthropists, corporate foundations, strategic partners, and government and foundation funders aligned with Greentown's mission
Build joint research relationships and collaborative grant opportunities with academic institutions through MoUs and research agreements
Author sophisticated, data-driven funding proposals and presentations that translate Greentown's impact into a compelling case for each funder, in writing and in the room
Develop and structure blended and recoverable capital, including recoverable grants, program-related investments (PRIs), and donor-advised funds, and articulate the value proposition for a blended-finance approach to scaling climate innovation
Once funding is secured, ensure a seamless handoff for ongoing donor stewardship, compliance, and grant reporting, and partner with the Finance team to build grant budgets and structure recoverable capital
Lead funder reporting and the stewardship of government and foundation relationships
Represent Greentown externally across climate, energy, philanthropy, and industry, including energy and climate trade associations, especially in Houston
Own and manage a personal portfolio of $2M to $10M and beyond, tracking pipeline movement, conversion, and renewals with discipline, and maintaining CRM hygiene and reporting as a discipline

Pillar 2 — Site Support for Annual Giving and Sponsorship (secondary focus, ~25%)

Work with Boston and Houston site leadership to shape and execute structured annual giving strategies
Build local sponsorship pipelines and support ecosystem funding opportunities at both sites
Develop frameworks, playbooks, and tools that let sites mobilize community and corporate support more consistently
Connect national fundraising narratives with site-level stories and relationships, and help sites identify and steward the right local major-gift prospects

Who You Are

You move easily between energy and climate, between philanthropic and partnership capital, between mission and business, and you believe the best outcomes come from connecting them. You are deeply motivated by Greentown's mission and energized by being in the field, building relationships and making the ask.

Qualifications

A proven major-gifts closer, with experience securing gifts from $100K to $5M and beyond, ideally in climate, energy, science, or innovation-adjacent organizations
A demonstrated climate background and deep commitment to the energy transition, able to articulate that conviction credibly to donors, partners, and skeptics across the political and sectoral spectrum, and to engage just as effectively with legacy energy companies
A deep, existing network in climate, energy, philanthropy, corporate innovation, or adjacent sectors, with relationships you are proud to bring to this work and a desire to grow them
A strong writer and storyteller who can turn a complex, technical climate story into a funding case that moves a donor, whether in a proposal, a deck, or a conversation
Fluency with the nonprofit capital stack and blended finance, including recoverable grants, PRIs, and donor-advised funds (DAFs), is a strong plus
Equally credible with a climate philanthropist and an energy or industrial executive, with no purity test
Highly relationship-driven and externally oriented, comfortable making the direct ask and confident driving to close
Politically and socially fluent across diverse stakeholders, from founders to philanthropists to industrial executives to civic leaders
Entrepreneurial and fast-moving, comfortable operating as a team of one in close partnership with the CEO while building toward a larger function

What Success Looks Like

A strong, activated national pipeline across priority donor segments: major climate philanthropists, family offices, foundations, and corporate partners
Early major gifts closed, with clear momentum toward the year-one revenue target
Structured, repeatable annual giving and sponsorship approaches underway with the Boston and Houston sites
Greentown established as a compelling platform for climate and energy-focused philanthropy and partnership capital
The groundwork laid for a longer-term major-gift pipeline and a future development function
Key university and research partnership opportunities identified and beginning to open new collaborative funding pathways
