We are Foundational.
Foundational is an early-stage, mission-driven startup solving one of the hardest engineering challenges of the decade: creating an exquisite, real-time understanding of Earth and orbit using ground-based lasers.
We aren't just gathering data; we are building the platform that will enable the next generation of space traffic control, resilient navigation, and Earth observation. - essential for the sustainability and resilience of the space domain, monitoring our climate and empowering the future economy.
This mission, this technology... will be foundational to the future of civilization.
The Role
As our core expert in optical tracking, you will be responsible for the full lifecycle of our SLR (Satellite Laser Ranging) and Space Debris Laser Ranging (SDLR) systems. You will bridge the gap between optical design, hardware integration, and the software algorithms required to close the link budget.
What You'll Be Doing
System Modelling & Simulation: creating comprehensive models for SLR and SDLR performance, including radiometric link budgets, atmospheric transmission, and detector probability of detection.
R&D of Novel Systems: Leading the design and integration of next-gen laser ranging architectures, selecting components (pulsed lasers, single-photon detectors, optics), and overseeing the assembly of optical benches.
Advanced Data Processing: Developing novel algorithms to process raw time-of-flight data, filtering noise from background photons, and refining orbital determination accuracy.
Deployment & Validation: managing the installation of optical ground stations and conducting rigorous Site Acceptance Testing (SAT) to validate ranging precision and pointing accuracy.
Laser Safety Leadership: Acting as a subject matter expert for laser safety, performing risk assessments, and ensuring compliance with UK/EU standards (e.g., BS EN 60825) for outdoor laser propagation.
Essential Experience:
Domain Expertise: Demonstrated experience designing, building, or operating SLR stations, Optical Ground Stations (OGS), or atmospheric LiDAR systems.
Atmospheric Physics: A strong understanding of laser beam propagation through turbulent media, including beam wander, scintillation, and the use of link budgets to predict system return rates.
Signal Processing: Proficiency in signal processing techniques specific to LiDAR/SLR (e.g., constant fraction discriminators, range gate optimization, and noise filtering algorithms).
Timing Systems: Hands-on experience with high-precision timing hardware (Event Timers, GNSS synchronization, PTP/NTP protocols) and an understanding of jitter/latency sources.
Software Stack: Strong proficiency in Python for instrument control (drivers, serial comms) and data analysis (NumPy, SciPy, Pandas). Experience with Linux environments is mandatory.
Astronomy Hardware: Familiarity with telescope mounts (equatorial/Alt-Az), star tracking, and pointing models.
Work Status: Must have the right to work in the UK.
Proactive & Self-Motivated: You thrive in a startup environment where requirements evolve, and you are comfortable working with autonomy.
Bonus Points (We'd love it if you...)
Experience with FPGA programming for timing applications.
Familiarity with orbital mechanics (TLEs, CPF/CRD formats).
Experience with optical design software (Zemax or Code V).
