Driven by our core values, we push boundaries, build with speed and intensity, and relentlessly deliver incredible value to our customers.

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 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 teams (Sales, Finance, Enterprise Systems, Analytics, Product, Design) and keeps stakeholders informed and unblocked.
• Track record of cultivating and managing senior relationships across Finance, Enterprise Systems, and Analytics to land durable solutions and accurate downstream reporting.
• Relentless about outcomes — you identify the highest‑leverage problems, remove roadblocks, and hold the bar on quality without slipping schedules.
• AI‑first mindset with a high bar for excellence: fluent in using AI tools to accelerate planning, execution, quality, and communication — and to inspire adoption across the team.

Bonus skills & attributes

• Experience with Stripe Billing or similar billing/subscription platforms; familiarity with usage metering and invoicing pipelines.
• Background in customer‑facing SaaS and/or scale‑up environments operating at high velocity.
• Experience leading operational excellence initiatives (on‑call, incidents, observability) for revenue‑critical systems.

What success looks like (first 30/60/90)

• 30 days: You understand the domain, architecture, on‑call posture, partner landscape, and active initiatives; you’ve built trust with engineers and partner leads and stabilized any urgent operational issues.
• 60 days: Clear, realistic roadmap and execution plan across platform, product health, and partner asks; visible improvements in on‑call rigor and update cadence; risks surfaced with mitigation plans co‑owned with Finance, Enterprise Systems, and Analytics.
• 90 days: Shipped at least one meaningful capability or reliability improvement; measurable progress on top business outcomes; staffing/skills gaps identified with a concrete plan to address them.

Team & domain

• Mission: Bill customers reliably and accurately, and provide core monetization and operational capabilities for Fin.
• Partners: Pricing & Packaging, Order, Self‑Serve, Sales, Finance, Enterprise Systems, Analytics, Billing Ops, Data/Analytics.
• Key areas: Subscription management, usage metering (e.g., Fin features), invoicing, revenue recognition data flows, admin tools, and ops workflows.
