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 end‑to‑end quality, especially for revenue‑impacting launches. Develop and retain top talent through coaching, clear expectations, and effective delegation; scale yourself via strong tech‑lead partnerships and “coach‑and‑delegate” leadership. Promote a culture of ownership, accountability, and incredibly high standards — moving quickly, communicating crisply, and celebrating wins. What skills do I need? 5+ years managing software engineering teams building and shipping customer‑facing or revenue‑impacting systems (e.g., billing, payments, pricing, subscriptions). Strong technical leadership: comfortable diving into architecture, debugging complex systems, reviewing designs, and making pragmatic tradeoffs to ship safely and fast. Proven ability to lead a cross‑functional, full‑stack team through planning and delivery with clear ownership of business outcomes and product health metrics. Excellent product sense and customer empathy — you translate ambiguous requirements into clear scopes, milestones, and measurable impact. Skilled communicator who drives alignment across partner
