Principal Software Engineer

Lead the technical strategy for moving HubSpot from a fixed SaaS subscription model to a flexible contracting platform that supports usage-based, commit-based, and enterprise-grade pricing structures.

Define and own the core architecture for contract lifecycle management, usage metering, entitlement enforcement, and pricing model extensibility — using our internal Corex contract orchestration framework as the foundation.

Make principled tradeoffs between correctness, compliance, and product velocity in a system where the stakes are financial.

Write production code regularly. Lead design reviews. Own large initiatives end-to-end, from architecture through rollout.

Drive multi-team technical efforts that span the three squads within Adaptive Monetization and require coordination across the broader fintech organization.

Turn ambiguity into clear technical direction and working software — and stay hands-on throughout.

Incrementally improve systems that cannot be rewritten from scratch. HubSpot's current contract infrastructure is load-bearing; this work requires surgical precision, not clean-slate thinking.

Bring the team with you — identifying paths forward that are safe to ship incrementally while maintaining reliability.

Raise the bar on resilience and observability in a system that generates dozens of production pages per day as the business shifts toward new pricing models.

Translate deeply technical architectural decisions for finance, compliance, legal, and executive stakeholders. This role requires you to operate effectively in rooms where the other people are not engineers.

Influence the product roadmap by helping leadership understand technical tradeoffs between speed, correctness, and long-term platform health.

Represent the engineering perspective on pricing strategy, contract flexibility, and go-to-market changes that require systems changes to support.

Mentor senior and staff engineers within Adaptive Monetization and across the broader Fintech org.

Partner with your peers — including the other Fintech principal engineers — to align on patterns that reduce complexity and increase reliability across the organization.

Participate in recruiting and help raise the hiring bar for technical talent in the fintech space.

Proven experience designing and evolving distributed systems with strict financial correctness requirements — billing infrastructure, payment processing, contract management, usage metering, or similar.

A background at a publicly traded company where audit rigor, compliance constraints, and real-money consequences shaped the way you built software. Engineers from Stripe, Block, Adyen, PayPal, or similar environments tend to arrive with the right instincts for this work.

The ability to operate effectively on complex, legacy systems that cannot be paused or rewritten — you know how to make progress incrementally while protecting reliability.

Strong executive communication skills. You can walk a CFO or compliance officer through a technical architecture decision, adapt the framing to what they care about, and leave the room with alignment.

A mentorship orientation. You're someone junior engineers seek out, and you measure your impact in part by how much better the engineers around you get.

Comfort with ambiguity. The system this role is responsible for is changing faster than it was designed to handle. You'll receive a lot of signal and need to make good decisions quickly.

Deep backend engineering expertise. This is not a platform, DevEx, or infrastructure role — the work is in the financial logic, data models, and service contracts that power HubSpot's monetization.

HubSpot's ability to offer commit-based enterprise contracts, charge based on usage, and compete for the largest, most complex customers in the market depends entirely on the contracting and monetization infrastructure this role will help build. This is multi-year work with direct revenue consequence and executive visibility — and the person who leads the technical architecture of this system will have a meaningful impact on what HubSpot can sell, and to whom, for years to come.
