Orbit Determination Engineer / Astrodynamicist

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

We actively champion underrepresented groups and seek to bridge gaps in our workforce. If you're excited by the role but don't match every point, or you’re seeking a part time role, please apply anyway and add a note into your application. Building the best team is our priority.
