Principal Software Engineer - Revenue HubNew$426K

The opportunity

Revenue Hub is building the backbone for businesses to sell, bill, get paid, and manage revenue inside HubSpot. Our systems handle billions of dollars in transactions, so correctness, clarity, and predictability matter.

What you'll do

  • Shape the technical roadmap across CPQ, Billing, and Payments with strong, opinionated patterns.

  • Define and evolve core domain models so pricing, products, contracts,: invoices, and payments behave predictably in the UI, over the API, and inside agent-driven workflows.

  • Design the API and platform contracts that let developers, partners, and AI: agents extend Revenue Hub without coupling to internals.

  • Create frameworks that make the platform easy to extend without adding complexity.

  • Write code regularly. Lead design reviews and build high-impact systems end-to-end.

  • Own large multi-team initiatives that span CPQ, Billing, and Payments.

What they're looking for

  • Take prototypes to production at scale.
  • Set patterns for extensibility, contract boundaries, financial correctness,: event-driven consistency, and how AI agents safely interact with commerce objects.
  • Push for simplicity where the domain wants to get complicated, and consistency where surfaces can drift.
  • Influence product strategy across CPQ, Buyer Portal, and Revenue OS.
