HubSpot’s Adaptive Monetization group owns the systems that determine how customers buy, contract, and pay for HubSpot — at scale, with direct financial consequence. Our infrastructure handles usage metering, contract orchestration, and subscription lifecycle management for every customer on the platform. An outage here doesn’t just affect user experience; it blocks customers from purchasing HubSpot entirely, and bugs typically produce immediate, measurable financial impact.
We’re in the middle of a multi-year shift to transform HubSpot’s straight-line SaaS subscription model and replace it with a flexible contracting layer that can support usage-based billing, commit-based pricing, and enterprise-grade contract structures. This work has executive visibility and is directly tied to HubSpot’s revenue growth and ships meaningful impact to our customers.
The core team for this role is roughly 15 engineers across 3 focused team, with an additional influence and impact radius that extends across approximately 180 engineers in the broader Fintech organization.
We’re looking for a Principal Software Engineer to help architect, build, and influence the evolution of HubSpot’s monetization model and strategy — and to do it incrementally, on a system that is live and load-bearing every day.
This is a hands-on technical role. Approximately 70-80% of your time will be spent writing code, leading designs, reviewing architectures, and owning technical direction on some of the most complex systems at HubSpot. The remainder will be split between cross-functional strategy, mentoring, and building technical credibility across the broader fintech engineering organization.
This is not a greenfield opportunity. The ideal person is someone who finds genuine satisfaction in making a complex, mission-critical legacy system incrementally better — and who can bring others along on that journey. If you’ve thrived at a publicly traded fintech company navigating the intersection of audit rigor, product velocity, and distributed systems complexity, this role was written for you.
