The ideal candidate has a Bachelor's degree, 2+ years of experience in backend development (preferably Python), and strong system design skills. Nice-to-haves include a Master's degree, 5+ years of experience, proficiency with Django/GraphQL, and specialization in optimization, performance, or distributed systems.

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

Who We Are
Loft: Space Made Simple.
Founded in 2017, Loft provides governments, companies, and research institutions with a fast, reliable, and simple way to deploy missions in orbit.
We integrate, launch, and operate spacecraft, offering end-to-end missions as a service across Earth observation, IoT connectivity, on-orbit AI, national security missions, and more. Leveraging our existing space infrastructure and an extensive inventory of satellite buses, Loft is reducing years-long integration and launch timelines to months. With more than 30 missions flown, Loft’s flight heritage and proven technologies enable customers to focus on their mission objectives.
With a growing fleet on track to reach 30 satellites by 2027, we are scaling up quickly across our offices in San Francisco, CA | Golden, CO | and Toulouse, France to meet accelerating demand for space infrastructure.
As an international company your resume will be reviewed by people across our offices so please attach a copy in English.
