[Hiring] Principal Software Engineer, Application Software @Zipline

Role Description

You’ll own high-impact software across one or more parts of Zipline’s application platform, such as:

• Partner, merchant, and internal operations tools that help teams run the business day to day
• Marketplace, fulfillment, billing, and support systems that connect demand, delivery, and financial correctness
• Network operations software for simulation, real-time visibility, intervention, orchestration, maintenance, and asset health
• Enterprise systems that power manufacturing, supply chain, inventory, traceability, finance, quality, and field operations

You’ll work closely with the people who use these systems every day, from operators and field teams to manufacturing, supply chain, finance, commercial, product, and partner teams. You’ll identify ambiguous problems, design durable systems, build production software end to end, and drive adoption.

Why This Role Is Unique

This team builds the software backbone of Zipline’s autonomous logistics network, turning complex real-world operations into reliable systems that scale. You’ll solve problems like:

• How do we give operators and partners real-time visibility into a complex physical network?
• How do we keep the network moving when demand shifts, weather changes, assets degrade, or capacity gets tight?
• How do we build financial and operational systems where every transaction, part, order, and aircraft state is traceable?
• How do we automate workflows across manufacturing, supply chain, fulfillment, and field operations without losing correctness?
• How do we design software that scales across countries, metros, verticals, and millions of deliveries?

These are production systems with immediate operational and business consequences. You’ll have real ownership, make technical and product decisions, and help shape how Zipline scales.
