Principal Software Engineer - Commerce
Job description
POS-9034
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. You’ll write code, dive into services, review tough designs, debug messy systems, and directly own the architecture behind some of the most critical surfaces in CPQ, Billing, Payments, and Revenue OS.
What You’ll Do
Build a simple, consistent, extensible platform
- 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 everywhere.
- Create frameworks that make the platform easy to extend without adding complexity.
Be a deeply hands-on, high-leverage builder
- 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
- Mentor senior engineers and tech leads.
- Drive thoughtful design decisions and guide learnings from incidents and large migrations.
- Help teams align on patterns that reduce complexity and increase reliability.
What You Bring
- Proven experience building and scaling distributed systems with strict correctness requirements.
- Background working with complex state machines, financial flows, or high-integrity data models.
- Strong architectural instincts with a bias toward simplicity, consistency, and well-defined boundaries.
- The ability to work horizontally across many teams and get alignment on platform patterns.
- A habit of turning ambiguity into clear plans and working software—and staying hands-on every step of the way.
