Profile match
Loft Orbital is a US space infrastructure company headquartered in San Francisco, California, that flies customer payloads and software on satellites it builds and operates, selling this as a satellite-as-a-service model. Founded in 2017 by Pierre-Damien Vaujour, Antoine de Chassy and Alex Greenberg, it handles spacecraft integration, launch booking, licensing and in-orbit operations for government, defense and commercial customers. It runs satellite integration and test facilities in Golden, Colorado and Toulouse, France, has an office in Abu Dhabi, and hires flight dynamics, flight software, test infrastructure and systems engineers.

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 onboardexecution
    • 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
  • Health and life insurance, we care about your health
  • Lunch Vouchers, because let’s be honest, we love food! (we even have a slack channel about it #loft-gourmand)
  • Cross-office travel opportunities between San Francisco, Colorado, and Toulouse to learn from our differences
  • Company and team off-sites and many other events to work & celebrate together
  • Relocation assistance to Toulouse when applicable
