Manager Fidelity Software Engineer Jobs in Michigan

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.

• Build the simulation platform: Develop the reusable infrastructure that powers simulation across the company, including execution, scheduling, orchestration, APIs, and developer tooling.
• Integrate with production software: Build interfaces that allow flight software, cloud services, embedded software, and hardware to execute inside deterministic virtual environments.
• Scale simulation: Scale from single-vehicle debugging to fleet-scale testing across thousands of scenarios in CI.
• Partner with engineers: Support teams building new tests, debugging failures, improving workflows, and expanding simulation capabilities.

• The Flight Software team uses simulation to validate onboard mission logic.
• The Test team uses it to explore pre-flight conditions and troubleshoot real-world anomalies.
• The Cloud team uses it to model server interactions like map updates, delivery instructions, and real-time comms.
• Full system Hardware-In-The-Loop testing framework uses simulation for flight software validation
• The Embedded and Ground teams use it to validate system integration, safety cases, and operational resilience.
• And the CI/CD pipeline relies on simulation to catch regressions before they ever reach a flight zone.

• 4+ years of professional software engineering experience in C++ or Rust (Rust experience is a strong plus).
• Demonstrated ability to reason about large software systems, APIs, concurrency, debugging, and software architecture.
• Deep experience architecting, building, or maintaining complex robotics, aerospace, or distributed systems simulations/digital twins.
• Expertise in concepts like time synchronization, inter-process communication, and determinism within a systems-level or real-time context.
• Familiarity with physical modeling, kinematics, dynamics, or robotics simulation concepts
• A passion for building enabling infrastructure and tools that allow Zipline engineers to simulate faster, test earlier, and deploy safer.
• Bonus: Experience scaling simulation in CI, HIL (Hardware-in-the-Loop), or formal verification methods.

• This role is onsite in the Bay Area due to frequent cross‑functional collaboration, access to flight test and HIL labs, and operational incident response.
• Occasional travel to field sites or test ranges may be required.
• Must be eligible to work in the US

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.
