How to Apply for Director of Federal Affairs
at Mainspring Energy
🏢 About Mainspring Energy
Mainspring Energy is pioneering a new category of power generation with its linear generator technology, offering a flexible and scalable path to a net-zero carbon grid. Unlike traditional engines or fuel cells, Mainspring's technology can run on any fuel—from natural gas to hydrogen and ammonia—making it uniquely positioned to accelerate the energy transition. Working here means joining a mission-driven team at the forefront of decarbonization, with direct impact on federal policy and funding that shapes the future of energy.
About This Role
As Director of Federal Affairs, you will be Mainspring's primary voice in Washington, D.C., shaping federal policy and securing critical funding to scale the company's technology. This role involves crafting advocacy strategies targeting the White House, DOE, and Capitol Hill, while building coalitions with industry partners to amplify Mainspring's influence. Your work will directly enable the deployment of innovative clean energy solutions, making you a key driver of the company's growth and the broader net-zero transition.
💡 A Day in the Life
Your day might start with a call with Mainspring's CEO to align on messaging for an upcoming congressional hearing, followed by a meeting with DOE staff to discuss a grant application for a hydrogen demonstration project. After a lunch with a trade association ally, you'd head to Capitol Hill for a meeting with a Senate energy committee staffer, then wrap up drafting a white paper on the grid benefits of flexible generation for an upcoming agency rulemaking.
🚀 Application Tools

- Existing relationships with influential members of Senate and House energy committees (e.g., Energy and Commerce, EPW, Energy and Natural Resources) and experience advancing bipartisan legislation.

📝 Tips for Applying to Mainspring Energy
Tailor your resume to highlight specific federal funding wins (e.g., 'Secured $50M in DOE grants for advanced energy storage') rather than generic advocacy achievements.
In your cover letter, explicitly name 2-3 current administration priorities (e.g., IRA implementation, hydrogen hubs) and connect them to Mainspring's technology.
Include a brief memo outlining a 90-day federal advocacy plan for Mainspring, demonstrating your understanding of their technology and policy landscape.
Leverage your network to get a warm introduction to Mainspring's CEO or SVP of Policy—mention any shared contacts in your application.
Quantify your experience with budget sizes, number of bills influenced, or size of coalitions built to show impact.

Based on this role, you may be asked about:
⚠️ Common Mistakes to Avoid
