Orbit Determination Engineer / Astrodynamicist
This is a future role. We're building a shortlist now and will contact you when it opens.
About us
Foundational is building the most precise picture of Earth and orbit, using lasers fired from the ground. We call it ground truth for orbit.
We design and run low-cost, autonomous satellite laser ranging stations. They measure the distance to satellites with extreme precision, day and night. Our data platform turns those measurements into tracking data and orbit products for satellite operators, space agencies and governments. We also build our own flight-proven laser retroreflector arrays, so any satellite can be tracked.
Our station network is expanding across Europe, South America, Africa and Australia. The data supports resilient navigation, Earth observation and the safe, sustainable use of space.
We're a small, fast-moving team of engineers, scientists and operators in London. We're backed by venture investors and supported by ESA, the UK Space Agency, Innovate UK and the European Innovation Council.
Position Overview
London · Full time · On-site
You'll build orbit determination products from our laser ranging data. They're a core part of what we offer customers, and you'll shape them from the start.
What you'll do
Develop and run precise orbit determination using laser ranging and other tracking data
Model forces and measurements: gravity, drag, solar radiation pressure, relativity, and station and spacecraft offsets
Build orbit prediction and ephemeris products, both for customers and for pointing our own stations
Validate against independent orbits, and quantify uncertainty
Turn algorithms into robust, tested software on our data platform
Work with customers on how they use orbit products
What you'll bring
An MSc or PhD (or equivalent experience) in astrodynamics, aerospace engineering or physics
Hands-on orbit determination (batch least squares, Kalman filtering) using real tracking data
Experience with Orekit, GMAT, GEODYN, ODTK or your own tools
Strong Python, C++ or Java
A solid grasp of time systems and reference frames
Nice to have
SLR, GNSS or DORIS processing
Space situational awareness or conjunction assessment
Covariance realism
Flight dynamics operations
What We Offer
A high-impact role with real ownership at an early-stage, venture-backed spacetech company
EMI share options (UK employees)
25 Days Annual Leave + Bank Holidays
Enhanced Parental Leave
Cycle to work schemes
Work alongside engineers and scientists across optics, lasers, software and astrodynamics
Offices in central London, with snacks, tea, coffee and regular socials
