About the role

Mission:

Sphere has built the world’s first AI-native tax engine that helps companies like Lovable, Eleven Labs, Replit, Runway AI, Windsurf (+ many more) automate their sales tax, VAT and GST obligations:

• We're growing rapidly (34%+ MoM revenue growth) and helping the fastest growing tech companies around the world including Lovable, Eleven Labs, Replit, Windsurf, Fathom, Linktree, Photoroom, Sierra AI, Zed etc

• We’ve spent the last 1.5 years building local rails into tax authorities in both the US and internationally to properly automate compliance processes (no other vendor has done this)

• We're building the world's first AI-native tax engine (which will be the foundation for a broader cross border compliance platform; think Deel for international billing)

• We're well funded by Felicis Ventures and YC

Sphere is looking for a Founding CSM based in SF to work closely with our Founder (who has been doing founder-led CS to date) and engineering team to help build out our CS function.

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; what Deel did for global payroll compliance we will do for global revenue-based compliance.

What you will do:

• Full stack CS: Triaging customer issues, helping maintain our industry leading Time To Resolution metrics, expading our customer contracts, assisting with technical implementation.

• Enhance our CS ops stack: We manage customer support in Slack and use Pylon as our infrastructure. We'll expect you to build on / improve that

• Build out CS processes / playbook: You have the chance to define our CS processes and build a team underneath you

• Ramp on compliance expertise: You're helping customers deal with cross border compliance - its a technical subject that requires expertise.
  

Your first 90 days will revolve around stabilizing inbound, protecting engineering time, and implementing repeatable systems that scale.

You’ll operate independently at first, building the foundation and workflows others will eventually scale with you.

What’s important to us:

• Hunter: Grit > pedigree.

• Fast shipper: If it can be done today, do it today.

• Self-starter: No hand-holding

• Accountability: You’ll be held accountable to objective, measurable targets each month.

• In-person: SF only.

Early success means faster customer response times, fewer engineering interrupts, and clear systems others can operate.

Requirements:

• Proven experience building out CS processes, teams, playbooks

• Early-stage startup experience (building processes from scratch).

• Comfortable navigating admin tools, reading API documentation, and handling basic data validation to resolve issues quickly.

Nice to have:

• Experience working with finance / accounting function
