Senior Software Engineer, Flight + Plan

Responsibilities

• Lead the design and implementation of mission-planning, scheduling, optimization, and operational-automation systems.
• Develop and validate algorithms for planning, search, scheduling, and resource-allocation problems across large solution spaces.
• Build high-performance APIs and distributed services for low-latency and compute-intensive workloads.
• Improve the scalability, reliability, observability, and operational readiness of mission-critical systems.
• Collaborate with software, program, product, operations, flight dynamics, satellite operations, and frontend teams.
• Drive complex software from technical design through production deployment and operation.
• Mentor engineers, help shape technical direction, and use automation and AI-assisted practices to improve engineering quality and velocity.

Requirements

• 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, resource allocation, constraint programming, mixed-integer programming, vehicle routing, heuristics, or related operations-research methods.
• Strong knowledge of algorithms, data structures, computational complexity, performance analysis, and system profiling.
• Experience with APIs, distributed systems, relational databases, and containerized cloud applications.
• Strong software-engineering fundamentals, including architecture, testing, CI/CD, observability, and modern Git-based workflows.
• Bachelor’s degree in Computer Science, Aerospace Engineering, Applied Mathematics, Operations Research, or a related technical field, or equivalent practical experience.
• At least 6 years of professional software-engineering experience involving backend systems, distributed systems, optimization, planning, modeling and simulation, or related technical domains.
• Demonstrated ability to independently drive complex software from concept and technical design through production deployment and operation.
• Active U.S. Secret security clearance and ability to maintain it throughout employment.
• U.S. citizenship or qualifying immigration status, or eligibility to obtain required U.S. Department of State authorizations, to satisfy ITAR requirements.
• Experience with flight dynamics, orbital mechanics, astrodynamics, spacecraft operations, aerospace modeling and simulation, cislunar mission design, trajectory planning, or Earth-Moon system operations is preferred.

Benefits

• Unlimited PTO, a minimum of 15 days off annually, and most U.S. federal holidays.
• Quarterly health and wellness benefits and comprehensive health insurance with 100% employee coverage.
• 4% 401(k) match.
• Annual four-day company offsite at destinations across the country.
• Collaborative small-team environment with opportunities to influence technology, culture, and company direction.
