About the role
CX has an unusually high important in a product like Sphere. Trust is of utmost importance when handling a company's payments and tax obligations. As a result, every user experience, modal, button, export needs to be flawless (would you trust Stripe with your payments if it was full of bugs and inconsistencies?). Sphere is looking for a passionate founding product engineer to own our CX, take it to the next level and help build out new features / products on our roadmap.
What they're looking for
- Strong experience with React. Our entire front end is built in react
- Strong experience with Figma. In order to collaborate efficiently with design
- Customer obsession. You’re going to be talking to a lot of people in the finance realm (Controller, Heads of Finance, Heads of Tax). You need to like them and obsess over them
- Very strong attention to detail. When you work with numbers this is a non-negotiable - it’s not enough to be 99% right
- Strong organization skills. We get hundreds of feature requests every day. How you monitor, organize and prioritize these is key
More about this role
Every breakthrough in trade infrastructure has followed the same pattern: reduce a transaction cost, expand the market. Containerization for goods. SWIFT for money. Stripe for payments. Compliance is one of the last and largest — and the hardest, because trade rules aren't data to be looked up. They're a complex adaptive system with 190+ sovereign jurisdictions, in different languages, changing constantly, reacting to each other.
Sphere built the system that solves it. Our AI (TRAM) ingests global trade law, interprets it, resolves conflicts across jurisdictions, and produces compliance determinations more reliable than human experts. We handle the entire lifecycle — calculation, registration, filing, remittance — at millisecond latency with zero downtime.
Backed by a16z and YC. $21M Series A, 30%+ month-over-month growth, customers include ElevenLabs, Replit, Deel, Runway, and Lovable.
