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.
Zipline is scaling the world's largest autonomous drone delivery network—a pioneering Physical AI system—delivering life-saving medical supplies and commercial goods globally. Our commitment to safety and exponential scale demands an industrial-grade virtual test environment, decoupled from physical hardware. That’s the mission of our Simulation team.
We are seeking a Simulation Software Engineer to build and evolve the core infrastructure that validates our entire robotics fleet software. This is not a standard simulation role; it is deep, systems-level software engineering focused on creating high-performance, high-fidelity digital twins that enable deterministic, faster-than-realtime testing of all autonomous safety-critical flight logic, cloud connectivity, and vehicle coordination across thousands of mission scenarios.
This role is absolutely critical for the safety and reliability of Zipline's real-world Physical AI deployment. If you are driven by the challenge of integrating complex flight software with synthetic environments, real hardware, and advanced time-manipulation to rigorously test an autonomous system, we want to hear from you!
This is not a niche role within Autonomy—it’s a company-wide enabler.
If your passion lies in building infrastructure that unlocks fast, safe iteration across multiple engineering domains, this role is built for you.
The starting cash range for this role is $180,000 - $220,000. Please note that this is a target, starting cash range for a candidate who meets the minimum qualifications for this role. The final cash pay for this role will depend on a variety of factors, including a specific candidate's experience, qualifications, skills, working location, and projected impact. The total compensation package for this role may also include: equity compensation; discretionary annual or performance bonuses; sales incentives; benefits such as medical, dental and vision insurance; paid time off; and more.
