About the Team
Commerce 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 for our customers, so correctness, clarity, and predictability matter. We’re creating an AI-first commerce platform that’s deeply integrated with HubSpot’s CRM - simple, consistent, and extensible across every part of the seller and buyer experience.
About the Role
We’re looking for a Principal Software Engineer to help shape the technical future of Commerce Hub. This is a very hands-on role.

- 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.
- Take prototypes to production at scale.
Lead architectural direction
- 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.
Partner deeply with product leadership
- Influence product strategy across CPQ, Buyer Portal, and Revenue OS.
- Help teams make clear tradeoffs between speed, correctness, compliance,and long-term platform health.
Raise the bar across the org
