Mission:
Sphere has built the world’s first AI-native tax engine that helps companies like Eleven Labs, Replit, Runway AI, Windsurf (+ many more) automate their sales tax, VAT and GST obligations:
As Sphere scales to support millions of customer transactions globally, the need for scalable infrastructure to support transaction syncing and live tax calculation within checkout and invoices is paramount.
Given we are a key part of mission critical billing flows for some of the fastest growing companies in the world, availability, resilience and speed are all key areas of focus that this role would be responsible for
Why this is a massive opportunity:
🌍 Massive TAM: Every business around the world needs this. Compliance isn’t optional.
🌬️ Strong macro tailwinds: Businesses are expanding globally at a faster pace, while tax authorities are cracking down on cross-border compliance, driving urgent demand.
✨ AI advantage: Incumbents can’t scale beyond the U.S.; our AI-native tax engine can.
🔮 Product vision: Indirect tax is just the start; we’re building the Deel for international billing.
