About the role
Lead the design and implementation of mission-planning, scheduling, optimization, and operational-automation systems Develop and validate algorithms that solve complex planning and resource-allocation problems across large solution spaces
What they're looking for
- Strong proficiency in Python and deep experience designing, building, and operating production backend systems
- Experience developing high-performance software for low-latency, compute-intensive, or data-intensive workloads
- Applied experience with optimization, scheduling, search, planning, or resource allocation, using techniques such as constraint programming, mixed-integer programming, vehicle routing, heuristics, or other operations-research methods
- Strong knowledge of algorithms, data structures, computational complexity, performance analysis, and system profiling
- Experience designing and troubleshooting APIs, distributed systems, relational databases, and containerized cloud applications
- Strong software-engineering fundamentals, including architecture, testing, CI/CD, observability, and modern Git-based workflows
More about this role
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 skills and sound...
