Chief of Staff

Substrate builds fintech infrastructure to grow America’s industrial GDP, starting with captive finance-as-a-service for equipment vendors.

Today, only the largest manufacturers like Caterpillar and John Deere offer financing in-house; everyone else sends customers to external lenders with outdated processes and tight credit boxes. Substrate unlocks in-house financing for the other 99.5%, enabling more sales and a new revenue channel.

In just a few months since launch, we've partnered with some of the largest machine sellers in the world—including auctioneers, dealers, marketplaces, and manufacturers—across manufacturing, construction, energy, agriculture, and more. Our vision is to own financing—the most critical transaction in equipment sales—and expand outward, like Stripe with payments, to build the financial operating system for equipment: insurance, banking, invoicing, warranties, liquidations, and more.

Our team comes from SpaceX, Anthropic, Ritchie Bros, Ramp, and other leading companies. We raised a seed round co-led by Floodgate (first investors in Lyft/Twitter) and the CEO of Holt, the biggest Caterpillar dealer in America.

We're hiring a Chief of Staff to lead projects across the business. This is a true founding, hands-on role for someone who wants creative ownership at an early-stage startup: you'll lead initiatives across every part of the company (product, GTM, talent, ops, finance), while being both strategic and deeply hands-on/tactical.

You'll work directly with the founder/CEO and senior leadership across operations, risk, and capital markets. You'll build the playbook as you go, drop into whatever matters most that week, and turn ambiguous problems into shipped outcomes. It's a "mini-COO" seat — one of the fastest ways there is to learn how an entire company gets built.

Some of the things you'll do:

• Drive GTM execution: run experiments, build campaigns, and visit customers at trade shows

• Own cross-functional projects end to end, from a rough problem statement to a shipped result, across product, GTM, capital markets, and ops

• Product management: write crisp PRDs, spec requirements, and work directly with engineers and designers.

• Run talent acquisition for hard-to-fill roles: source candidates, manage the pipeline, and help us hire exceptional people

• Prepare investor, board, and fundraising materials for investors

• You believe in objective good and beauty, and you want to bring them to an antiquated, predatory industry.

• You believe not all technology is created equal. You don’t care about building another enterprise SaaS tool, you want to build tools that advance civilization.

• You want to work with people who treat their work as craft, who violently reject “just good enough,” and you want to help build that culture.

• Deeply curious. Your friends would describe you as a "voracious learner."

• Extraordinarily organized and detail-oriented. You can drill to the atomic unit of any task or workflow and understand it from first principles, without someone building the system for you.

• Have both breadth and depth. The surface area here — debt markets, AI, equipment verticals, sales, product, GTM, investors — is enormous, and you're the kind of person who can absorb things fast and execute.

• Have a track record of high ownership in demanding environments — a startup, consulting, banking, or a serious operating role. (We care more about horsepower, judgment, and drive than a specific number of years)

• Will do what it takes to win.

• Able to travel ~once per quarter for trade shows and vendor visits.

• Are excited to help build this company — and its culture — from the ground up, and aligned with all of our Cultural Principles.

• SF preferred, but not required

• $110K-$140K base

• $35K-$90K equity

• 401K

• Medical, dental, and vision insurance fully covered
