You'll work on a small and driven team, developing our flight dynamics software stack so that it can: - Scale to fly 50+ satellites in orbit in a highly automated, reliable, and safe (from a collision avoidance perspective) manner - Enable new conops and customer missions with demanding orbit determination, stationkeeping, and attitude performance requirements We're looking for someone with a solid theoretical understanding of astrodynamics, operational flight-dynamics experience, and software-engineering foundations. If you enjoy solving hard problems and working in a fast-paced and supportive environment, we'd love to hear from you. ### About this role: - **Implement and improve upon algorithms** for orbit determination, orbit propagation, maneuver planning (stationkeeping/orbit transfer), conjunction assessment, collision avoidance, and attitude modeling, contributing to our open-source astrodynamics tooling that powers both flight operations and simulation work across the company - **Develop and maintain the in-house flight dynamics ground software backend applications** that compute, store, and serve our fleet’s ephemerides, maneuvers, conjunctions, target orbits, etc - **Interface with systems and mission engineers** to help translate technical mission requirements and customer demands into operational outcomes in orbit - **Support satellite operations engineers** by providing astrodynamics expertise during LEOP/anomalies/conjunction response and assisting with configuring our software stack for various customer missions ### Must Haves: - Bachelor's degree in physics or an engineering discipline - Deep technical understanding of some of the following topics: orbital mechanics, state estimation, spacecraft maneuver planning, conjunction assessment, and spacecraft attitude modeling - Fundamentals of numerical methods: solvers, optimization, and simulation techniques - Experience with designing and developing software libraries and backend services, preferably in Python. - Excellent communication skills, both written and verbal ### Nice to Haves: - Master’s degree in physics or an engineering discipline - Proficiency in astrodynamics tools such as STK, Astrogator, GMAT, OreKit, Monte, Copernicus, OpenSpaceToolkit, or equivalent. - Demonstrated practical experience in spacecraft constellation flight dynamics operations - Demonstrated practical experience building high-performance backend software applications and/or libraries - Capable of solving complex problems within a highly collaborative environment ### 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](https://loftorbital.slack.com/archives/C02G64537DF)) - 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  _\*__Research shows that while men apply to jobs where they meet an average of 60% of the criteria, women and other underrepresented people tend to only apply when they meet 100% of the qualifications. At Loft, we value respectful debate and people who aren’t afraid to challenge assumptions.  We strongly encourage you to apply, even if you don’t check all the boxes._ **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._ ## Other open roles at Loft Orbital - [Flight Dynamics Software Engineer](https://zerogtalent.com/space-jobs/loft-orbital/flight-dynamics-software-engineer-d2ec023c-42c4-4cf3-a891-9230d0811cc0) — San Francisco, CA - [Flight Dynamics Software Engineer](https://zerogtalent.com/space-jobs/loft-orbital/flight-dynamics-software-engineer-c6d4fb42-d7e3-46ef-bdaf-299c372b7dd4) — Golden, CO - [Senior Software Engineer - Test Infrastructure](https://zerogtalent.com/space-jobs/loft-orbital/senior-software-engineer-test-infrastructure-e8738078-ebca-4398-9a5b-070256885382) — San Francisco, CA - [Senior Software Engineer - Test Infrastructure](https://zerogtalent.com/space-jobs/loft-orbital/senior-software-engineer-test-infrastructure-e772a052-ec50-4578-8718-0a8b12ca55b6) — Toulouse, Occitanie - [Senior Software Engineer - Test Infrastructure](https://zerogtalent.com/space-jobs/loft-orbital/senior-software-engineer-test-infrastructure-7a06a11c-32ea-4fd2-a0bc-4f96561218a0) — Golden, CO --- *Source: [Zero G Talent](https://zerogtalent.com), the job board for space, defense, AI, robotics and frontier-tech companies.*
