Loft Orbital is looking for a Backend Software Engineer to join the Mission Platform organization.
You'll work on a small and driven team, developing a brand new software product that optimizes tasking across a large heterogeneous constellation of multi-sensor satellites:
-
scale to fly 50+ satellites, serving 100,000s of customer tasking orders
-
design, build and optimize a brand new product from scratch
-
solve challenging problems across multiple domains:
-
Astrodynamics, satellite capacity modeling and simulation
-
Back-end/API performance
-
Low latency, high responsiveness system design
-
Mathematical optimization and scheduling problems
-
We're looking for someone with a solid background in software engineering, ideally with a proven track record of building systems from scratch and solving complex, system-level problems. The ideal candidate can operate independently in a fast-paced environment and challenge requirements.
About this role:- Develop and improve a new software product that manages customer orders across a multi-sensor constellation of satellites
- Interface with teams to help design the customer-facing interfaces and the back-end pipeline that goes from a plan to onboard execution
- Build tools and services that help sales and operators understand current and future capacity, operational risks and opportunities for growth
- Solve complex multi-objective optimization problems that maximize collection capacity, balancing various (conflicting) customer constraints, and help define what “optimal” means
- Design systems of systems: decompose complex problems into well-bounded services with clear interfaces, and reason about how they interact, fail, and scale together
- Bachelor's degree in Software Engineering, Physics/Astrodynamics, Mathematics or a related field
- 2+ years of experience with designing and developing software libraries and backend services, preferably in Python
- Proven track record of operating independently and solving complex problems
- Experience with system design
- Excellent communication skills, both written and verbal, for technical and non-technical audiences
- Master’s degree in Software Engineering, Physics/Astrodynamics, Mathematics or a related field
- 5+ years of experience designing and developing software libraries and backend services, preferably in Python
- Proficiency with Django/GraphQL stacks
- Hands-on experience operating spacecraft
- Experience with C++ / high-performance Python (vectorization, JIT compilation like Numba, GPU parallelization)
- Demonstrated practical experience building high-performance backend software applications and/or libraries
- Specialization in one of the following disciplines:
- Integer/linear/multi-objective optimization or other Operations Research style problems
- Back-end/API performance optimization
- Distributed systems
- Security
- Earth observation tasking
- High-performance computing
