E-Invoicing Lead

ABOUT SPHERE

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.

Small team, global surface area. Everyone owns a domain that would be a full team at a larger company. San Francisco, five days in office.

The problem keeps compounding. Expanding into input tax, withholding, e-invoicing, tariffs — each multiplies the complexity. Tens of millions of transactions today, billions ahead.

THE ROLE

We're looking for an experienced leader to own our global e-invoicing strategy and help build a best-in-class e-invoicing platform for our customers. In this role, you'll combine deep expertise in global indirect tax and e-invoicing regulations with strong product and systems thinking to design scalable solutions that enable customers to comply with rapidly evolving global mandates.

You'll work at the intersection of Tax, Product, and Engineering, translating complex regulatory requirements into product capabilities that can be deployed across dozens of countries. You'll define the roadmap for our e-invoicing offering, prioritize market expansion, and ensure our platform remains ahead of global regulatory change.

This is an opportunity to shape one of the company's core products and help define how businesses manage tax compliance in an increasingly digital world.

WHAT YOU'LL DO

• Within days: Serve as the company's subject matter expert on global e-invoicing, real-time digital reporting requirements, and related indirect tax regulations
• Partner closely with Product and Engineering to translate regulatory requirements into scalable product features and technical requirements.
• Define country-specific business requirements, validation rules, invoice schemas, and compliance workflows for new market launches.
• Identify opportunities to simplify implementation, reduce operational complexity, and improve the customer experience.
• Within months: Own the global e-invoicing strategy for our platform, defining the roadmap and priorities for expanding our product across international markets.
• Monitor emerging global e-invoicing regulations and proactively incorporate regulatory changes into our product roadmap.
• Prioritize implementation efforts based on customer demand, regulatory deadlines, and strategic business objectives.
• Collaborate with Customer Success, Sales, Solutions Engineering, and Implementation teams to support customer onboarding and successful deployments.
• Represent the company internally and externally as a trusted expert on global e-invoicing and digital tax compliance.
• Build the foundation for a world-class global e-invoicing program that enables customers to confidently comply with evolving tax regulations.

REQUIREMENTS

• 8+ years of experience in indirect tax, tax technology, VAT/GST, or global tax compliance.
• 3+ years direct e-invoicing experience
• Experience designing or implementing e-invoicing solutions across multiple countries.
• Strong experience partnering with Product and Engineering teams to build tax technology products.
• Demonstrated ability to translate complex regulatory requirements into scalable product specifications and technical requirements.
• Excellent program management skills with experience leading complex cross-functional initiatives.
• Strong communication and stakeholder management skills, with the ability to work effectively across technical and non-technical teams.
• Strategic mindset with the ability to balance regulatory requirements, customer needs, and product scalability.
• NICE TO HAVES
• Experience building or managing a commercial e-invoicing platform or tax technology product.
• Experience with PEPPOL, clearance models, CTC frameworks, and real-time reporting systems.
• Experience integrating with ERP systems such as SAP, Oracle, Microsoft Dynamics, or NetSuite.
• Familiarity with APIs, distributed systems, and enterprise software architecture.
• WHO YOU ARE
• You'll thrive here if: You're a Dog. You've been underestimated, gone through struggle, and never stopped running. You have a chip on your shoulder and enormous drive. You look at Stripe, Deel, and Flexport all punting on compliance and think:
• good, that means the opportunity is ours.
• Hunger beats pedigree.
• Early stage is in your bones. You've built things where there's no playbook and nobody handing you the answer. You define the problem instead of waiting for instructions.
• You own it end to end. Give you a goal and you figure out your own path. Small team, global surface area — everyone owns a domain that would be a full team at a larger company. No one tells you how.
• You believe speed and accuracy are both possible. We're building a complex product that requires robustness and 100% uptime, and we have to build at our customers' pace. Move fast. Don't break things. Both.
• This won't be a fit if: You need structure handed to you or ambiguity feels draining rather than motivating
• You want to manage people more than own hard problems (we're a flat, experienced team — everyone builds)
• You're used to "good enough" shipping (small errors have outsized impact here)
