AI Product Engineer

We’re financing the future of energy

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 of 100+ is composed of experts in energy, tax, finance, government, and technology. We have raised $77 million in capital from some of the best 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.

An inflection point in American energy and manufacturing

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 financing 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.

About the role

The traditional process for financing clean energy is manual, opaque, and slow. We’ve built products that solve part of that problem — now we’re expanding their breadth and depth with AI.
