# Senior Software Engineer, Flight + Plan

What You’ll Be Doing As a Senior Software Engineer on Quindar’s Flight + Plan team, you will lead the design and development of mission-planning systems that support real-world spacecraft operations. Your work will focus on optimization, scheduling, operational automation, and high-performance backend services across Quindar’s platform. You’ll work primarily in Python to build reliable production systems that solve computationally demanding planning problems. These systems must process large search spaces, respond with low latency, and scale from individual spacecraft to large satellite constellations. You’ll develop and validate algorithms, design distributed services, and improve the performance and operational resilience of mission-critical workflows. This role sits at the intersection of optimization, backend software engineering, and space operations. You’ll collaborate closely with software engineers, flight dynamics engineers, satellite operators, frontend engineers, and product leaders to turn complex operational requirements into maintainable and scalable software. We’re looking for an engineer who combines strong software fundamentals with mathematical problem-solving ski
