Simulation Software Engineer

Join Zipline, the world's largest autonomous drone delivery network, as a Simulation Software Engineer. In this critical role, you will build and evolve the core infrastructure that validates our entire robotics fleet software. You will work 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 essential for the safety and reliability of Zipline's real-world Physical AI deployment and will have a company-wide impact.

• Construire et faire évoluer l'infrastructure de simulation qui valide l'ensemble du logiciel de la flotte de robots.
• Développer l'infrastructure réutilisable qui alimente la simulation à travers l'entreprise, y compris l'exécution, la planification, l'orchestration, les API et les outils de développement.
• Intégrer le logiciel de production et construire des interfaces qui permettent au logiciel de vol, aux services cloud, au logiciel embarqué et au matériel d'exécuter dans des environnements virtuels déterministes.

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