Staff Product Manager, Fintech - Billing

Engine is a fast-growing company transforming business travel into a personalized and rewarding experience. They are seeking a Staff Product Manager to lead the development of innovative billing strategies and enhance the billing platform, collaborating with various teams to create customer-centric solutions.

Responsibilities:

• Craft and execute innovative strategies to modernize Engine's end‑to‑end billing architecture—covering statements, invoices, folios, receipts, and direct bill—so customers can pay us quickly and accurately at scale
• Collaborate with engineering, accounting, finance, and customer-facing teams to deeply understand how different customers obtain approvals and reconcile their books, and turn those insights into flexible, reliable billing experiences
• Lead the evolution of our billing platform and integrations (e.g., into customers' accounting and ERP tools) to enhance efficiency, resilience, and scalability—ensuring that upstream changes across travel and fintech systems still produce accurate, trustworthy billing artifacts
• Design billing experiences that support how customers actually review, approve, and reconcile charges, simplifying complex accounting and invoicing workflows into intuitive, self-serve tools that enable customers to bill their own clients and pay Engine accurately and on time

Requirements:

• 5–8+ years of hands-on product management experience, including significant time owning billing, invoicing, accounting, or internal financial systems (e.g., statements, folios, ledgers, approvals, AR/AP workflows)
• You're a highly structured problem-solver who's comfortable with complex, numbers-heavy domains
• You break ambiguous, interdependent problems into clear, executable milestones
• You've shipped products that improved invoice accuracy, time-to-payment, or billing automation
• You collaborate deeply with engineering, accounting/finance, and customer-facing teams
• You communicate clearly with both technical and non-technical stakeholders
• Bonus points if you've built or integrated with accounting or finance tools (e.g., QuickBooks, Coupa, or similar), or have experience designing internal platforms that support high-scale B2B billing
• Familiarity with large, distributed systems and data integrity concepts is a plus
• You're energized by untangling complex workflows and turning them into simple, reliable customer experiences
• You're comfortable in a fast-moving environment, ready to roll up your sleeves with cross-functional partners, and focused on delivering incremental, high-impact improvements—getting from 0→10, then 10→100
