What’s the opportunity?

Join Fin as a Senior Engineering Manager to lead Team Billing — the group that owns the core systems powering how customers buy Fin, how we meter usage, bill accurately, recognize revenue, and keep money flowing. This is a high‑impact, high‑visibility role at the heart of Growth Engineering, partnering closely with Pricing & Packaging, Order, Self‑Serve, Sales, Finance, Enterprise Systems, Analytics, and Billing Operations. You’ll drive clarity, focus, and execution across a mission‑critical platform while fostering a culture of ownership, accountability, and incredibly high standards.

What will I be doing?

• Lead and scale a team building and enhancing Fin's billing, subscription, invoicing, and metering capabilities — the backbone of revenue and monetization experiences.
• Own and improve the reliability and operational excellence of Billing systems: on‑call quality, incident response, observability, and product health standards.
• Partner with Senior and Staff Engineers to shape and execute the technical strategy across subscription management, metering, invoicing, and integrations (e.g., Stripe Billing) — balancing near‑term needs with long‑term platform evolution.
• Collaborate deeply with Product, Design, Sales, Finance, Enterprise Systems, Analytics, and Billing Ops to prioritize the roadmap, close operational gaps, and deliver measurable business outcomes each quarter.
• Cultivate and manage trusted relationships with partner leaders in Finance, Enterprise Systems, and Analytics to ensure alignment on data flows, compliance, reconciliation, and business reporting needs.
• Drive migrations and modernization work where needed (e.g., Stripe‑first capabilities, systems parity and improvements), ensuring safe change management and robust downstream data flows.
• Bring clarity and alignment to priorities, tradeoffs, and timelines; set a high bar for planning, testing, and
