What You Will Own

• Network Operating Center software for real-time operational visibility and intervention across aircraft, sites, missions, weather, and demand
• Fleet orchestration systems for assignment, routing, scheduling, and rebalancing
• Maintenance and asset health systems that connect issue detection to return-to-service
• Simulation and validation platforms that evaluate topology, load, and policy changes before they reach production

How We Work

This team operates with high ownership, high trust, and a high technical bar. Engineers are expected to identify important problems, form a clear view of how the system should work, and drive solutions from concept through production. We also expect engineers to use AI tooling effectively as a force multiplier across exploration, implementation, and debugging, while maintaining strong engineering rigor, judgment, and accountability.

What You Will Bring

• A track record of turning ambiguous, high-stakes systems problems into production software others rely on
• Combine strong systems judgment with product instinct and care about solving the real operational problem
• Simplify complexity, define durable abstractions, and improve the architecture around you
• Care deeply about reliability, correctness, and operator trust
• Thrive in environments where software, operations, hardware, and product intersect
• Want to shape architecture and operating models, not just implement scoped features
