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. 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. Much of this framework doesn’t exist yet — and you’ll help invent it using first principles. ## WHAT YOU'LL DO - Collaborate directly with customers - Build products from 0 -> 1 - Pick the tools & frameworks we use - Learn an insane amount about the nuts & bolts of clean energy finance - Raise the bar for our engineering culture ## WHAT WE’RE LOOKING FOR - 4+ years of full-stack software engineering experience and you can build products end-to-end (frontend + backend) - Bonus: fluency in NextJS + React + Typescript stack - Also bonus: you are comfortable making UX decisions - Proven experience building and shipping user-facing LLM products - Bonus: you have iterated on a product through evals & CI/CD - Ability to thrive in a fast-paced environment - Bonus: you love working at startups - Excellent communication skills (oral & written) - Bonus: also excellent at communicating with AI (prompting) YOU MIGHT EXCEL IF YOU... - Enjoy hackathons & building side projects - Have experience building AI agents that work - Previously founded a startup OR worked at a rocket ship - Love taking products from 0 -> 1 - Can do most things in half the time that most people think possible - Can quickly find the 80/20 solution and move on - Can unblock yourself and rally others ## WHAT WE BRING - Backing, traction & brand: - 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. - Additionally, we have raised a $500mm debt facility from Nuveen, allowing us to co-invest and deploy our own capital in support of the clean economy. - Have been profitable and are growing exponentially - We have closed over 120+ transactions in just the last 2 years, facilitating billions of dollars of capital flowing into renewables projects - Culture & working dynamic - Remote-first operating model: Work from anywhere in the US and Canada, or work out of our optional offices in DC (open), NYC (opening Q1’26).
