## Job description

**Wanna join the adventure?**

| 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

#### Must Haves:

- 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

#### Nice to Haves:

- 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

#### Some of Our Awesome Benefits:

- Equity, we want you to have an active role in our success

- Up to 35 days of Paid Time Off (vacations & RTT ) and flexible working hours, we want you to be at your best
