About the job

Wanna join the adventure? Loft Orbital is looking for a Backend Software Engineer to join theMission 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 w ith teams to help design the customer-facing interfaces and the back-end pipeline that goes from a plan to onboard exec ution

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

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.
