Senior Engineer, Revenue SystemsLocation: NYC
Reports to: CTO
The RoleRevenue systems are the connective tissue between what we sell and what we ship. We're hiring a Senior Engineer to own that surface-the integrations, data models, and pipelines that keep contracts, usage, and invoicing consistent and correct as we scale.
Strong software engineering experience is the requirement. Revenue systems domain experience matters more than payments-infrastructure-from-scratch experience. The job is correctness: making sure the right things get billed, that HubSpot, our platform, and Tabs agree with each other, and that the whole pipeline runs without manual intervention.
This is a senior IC role with broad ownership and real architectural influence.
What You'll Own- HubSpot integration - deal terms and contract data flowing reliably into the platform; CRM and platform staying in sync
- Contract and entitlement modeling - representing what's billable, what's recognized, and how contract terms map to data
- Tabs integration - usage and entitlements flowing out to invoicing automatically and correctly
- Reconciliation - keeping multiple sources of truth consistent and surfacing discrepancies before they become problems
- Integration standards - establishing the quality bar for how revenue-systems integrations get built and maintained going forward
What We're Looking For- Strong systems integration and data modeling skills - API/webhook integration, reconciliation, keeping sources of truth consistent
- Revenue or accounting domain sense - you understand how contracts, usage, and entitlements map to money
- Comfortable building greenfield against tools that aren't fully spec'd yet
- Production experience in Python and/or TypeScript
- A correctness-first mindset - edge cases in billing aren't acceptable
Even better if you have:- Experience with CRM integrations (HubSpot, Salesforce, or similar)
- Background in billing, invoicing, or usage-based pricing systems
- Familiarity with B2B SaaS contract models - seat licenses, usage tiers, entitlements
- Experience scaling revenue operations without adding headcount per customer
How to ApplySend a cover letter describing:
- A system you've built to keep two or more data sources consistent
- How you think about correctness in financial or billing contexts
- Tools and languages you'd reach for on day one
