About Zipline

Zipline is the world’s largest and most experienced drone delivery service. We are on a mission to serve all humans equally by ensuring access to food, medicine and essential goods anytime, anywhere. We design, build, and operate the world’s largest autonomous logistics system, delivering critical supplies quickly and reliably. Today, Zipline operates on four continents, makes a delivery somewhere in the world every 30 seconds, and has completed millions of deliveries to date, including blood, vaccines, medical supplies, food, and retail products.

Our customers include the world’s largest and most prominent healthcare systems, governments, retailers, restaurants and global businesses who rely on us to save lives, reduce emissions, increase economic opportunity, and provide delivery from point A to point B as fast as possible. The drone is only 15% of what we’ve built to enable seamless, reliable, global operations.

Our system strengthens supply chains, reduces congestion, and gives people time back. With more than 140 million commercial autonomous miles safely flown, Zipline is redefining access to healthcare, consumer products, and food across the globe.

We operate at a global scale and are looking for practical problem solvers who thrive on real-world challenges and rapid growth. Our team is motivated by building systems that have a direct, meaningful impact on people’s lives and by scaling the future of logistics. We are seeking people who sculpt from first principles, enjoy facing adversity, and can do the impossible at record breaking speeds.

About You And The Role

As a Senior Software Engineer on the Financial Platform team, you will build systems that turn Zipline’s operational activity into accurate, auditable financial records. Flights, deliveries, inventory movements, manufacturing events, and partner transactions must be billed, settled, reconciled, and recorded correctly for Zipline to operate and scale globally.

Your immediate priority is strengthening the operational-event-to-financial-record workflow: creating traceable, automated paths from real-world activity through billing, settlement, reconciliation, and ERP recording. You will work directly with Finance, Commercial, Manufacturing, Operations, Data, and Marketplace Engineering to replace manual processes with durable software.

What You’ll Do

• Design and build backend services and full stack apps for financial event processing, billing, pricing, taxation, settlements, reconciliation, inventory costing, and ledger workflows.
• Build idempotent, replayable, ordered, and auditable event‑driven systems that trace each transaction from an operational event through accounting.
• Translate accounting, finance operations, and commercial workflows into scalable software in partnership with domain stakeholders.
• Integrate operational systems with our custom ERP system, payment providers, tax engines, banking systems, manufacturing systems, and partner platforms.
• Automate reconciliation and manual accounting workflows to reduce settlement errors, improve financial accuracy, and accelerate month‑end close.
• Own reliable APIs, data models, service boundaries, observability, service‑health metrics, and runbooks for correctness‑critical production services.
• Drive technical design, review code and designs, mentor engineers, and lead projects from concept through production.

What You’ll Bring

• 5+ years building production backend systems and owning reliable services at scale.
• Strong distributed‑systems design skills, including thoughtful data modeling, API design, and pragmatic architectural tradeoffs.
• A rigorous approach to consistency, idempotency, transactional integrity, event ordering, failure recovery, and financial correctness.
• Experience working directly with business stakeholders to understand complex workflows and deliver practical software solutions.
• Willingness to participate in an on‑call rotation and improve reliability through observability, incident reviews, and automation.
• Regular on‑site presence in South San Francisco to partner closely with Finance and engineering teams.
• Prior experience with billing, payments, ERP integrations, reconciliation, accounting systems, ledgers, or marketplace settlements is strongly preferred; it is not required.
