Sr. Accountant

Crux is the capital platform for the clean economy. We modernize capital raising and deployment for clean energy and critical infrastructure with solutions across advisory, investments, technology, and intelligence.

Our team is composed of experts in energy, tax, finance, policy, tech, and beyond. We have raised $77 million in capital from top investors, including Andreessen Horowitz, Lowercarbon Capital, New System Ventures, Overture, Ardent Venture Partners, QED, Canapi, and others. These funds are joined by strategic investors including Pattern Energy, Clearway Energy, EDF Renewables, Intersect Power, LS Power, Orsted, Hartree Partners, Liberty Mutual Strategic Ventures, MassMutual Ventures, and OMERS Ventures.

Energy demand is growing for the first time in decades, driving an urgent need for more affordable and reliable electricity. More electricity requires new clean energy infrastructure and strong domestic supply chains for minerals and components as well as large amounts of capital.

Traditional project finance is opaque, fragmented, and analog. At Crux, we’re changing that. Through unmatched insights and expertise, white-glove service, purpose-built tools, and risk underwriting, we power a more prosperous, clean, and secure energy future.

We are scaling quickly and looking for team members who are eager to combine deep expertise with an AI- and tech-forward mindset.

We’re hiring a Senior Accountant to own the transactional layer of our accounting function: spend, payables, receivables, cash, and reconciliations across a growing group of entities. You will make sure the data flowing through our systems is accurate, complete, and trusted by the people who rely on it.

This is an ownership role. You will run your areas end to end, spot what is breaking before it becomes a problem, and build the processes and controls that let us scale. You will work closely with teams across Crux, so you need to be as comfortable coaching a coworker on expense policy as you are tying out a bank reconciliation.

You are detail-oriented but see the bigger picture, and you build systems that support long-term growth. You prioritize well in a fast-paced, high-stakes environment. You are comfortable in gray areas and take ownership even when the path forward is not fully defined.

AI is central to how our accounting team works. You will build and run AI-assisted workflows as a core part of this role.

You will report to our Senior Accounting Manager and work alongside a small, hands-on team that already has strong documentation and processes in place. We move quickly, and people who take ownership are given room to grow.
