AI Product Engineer

Crux is the capital markets platform changing the way clean energy and manufacturing projects are financed in the U.S. Crux's capital markets platform, software platform, market intelligence, and expert team help developers and manufacturers unlock financing.

Our team of 65+ is composed of experts in renewable energy, project & corporate finance, tax equity and tax credits, policy, and technology and AI.

We have raised $77 million in capital from some of the best venture and strategic investors, including Andreessen Horowitz, Lowercarbon Capital, New System Ventures, Ardent Venture Partners, Pattern, Clearway, EDFR, Intersect, LS Power, Orsted, Hartree Partners, Liberty Mutual Strategic Ventures, MassMutual Ventures, and OMERS Ventures.

Energy demand is growing for the first time in 20 years, driven by surging manufacturing, transportation, electrification, and data centers. Simultaneously, hundreds of billions of dollars are being invested in domestic supply chains for critical minerals and components. Developers and manufacturers will require trillions of dollars in capital to meet growing needs.

Before Crux, the capital markets supporting this transformation remained opaque, fragmented, and complex. At Crux, we recognized the missing infrastructure: a central capital markets platform designed specifically for the next century of American energy and industry. We unlock faster decision making, lower cost of capital, and accelerated investment.

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. We're hiring our first AI Product Engineer to work hand-in-hand with customers, product, commercial, and legal teams to reimagine the way transactions happen in clean energy finance, starting with diligence.

You won't just be building features — you'll be co-designing the processes and systems that define how we ship high-quality AI products at Crux.
