Job description

Wireless Communications Engineer - UK

The Opportunity

Lead the development of a pioneering global satellite communications network integrating high-speed, resilient links across NGSO constellations, aerial assets, and ground infrastructure. This role is central to solving the hardest problems in high-capacity, low-latency data transfer specifically, designing and optimizing links for dynamic, space-based environments.

Key Responsibilities

Link Design & Optimization: Architect, model, and validate NGSO inter-satellite (ISL) and satellite-to-ground (SGL) links utilizing Optical (Lasercom/FSO) and/or mmWave (E/V/Q-band) technologies.

Dynamic Channel Modeling: Develop high-fidelity models for the physical layer (PHY) performance in space, accounting for rapid Doppler shifts, pointing/tracking errors, and atmospheric/scintillation effects in SGLs.

Phased Array & Antenna Systems: Specify, analyze, and oversee the integration of advanced phased array antennas and high-gain optical terminals optimized for SWaP (Size, Weight, and Power) constraints on spacecraft.

DSP & Control Algorithms: Design and implement adaptive equalization, beam steering, and Kalman filter-based tracking algorithms to maintain link integrity and maximize throughput in high-mobility scenarios.

Protocol & Networking: Collaborate on defining and optimizing communication protocols (e.g., synchronization, handover, routing) necessary for a reliable, multi-node, meshed space network.

Technical Requirements

Specialized experience in the design and development of satellite communication systems, with a strong preference for NGSO/LEO/MEO constellations.

Demonstrated expertise in Physical Layer (PHY) development for high-capacity (10s of Gbps) space or terrestrial systems.

Mandatory hands-on experience in one or both core technologies:

Space-to-Ground/Inter-Satellite Optical Communications (Lasercom/FSO): Proficiency in link budgets, atmospheric models, acquisition, pointing, and tracking (APT) systems.

High-Frequency RF (mmWave): Deep understanding of E/V/Q-band link analysis, terminal design, and beamforming for mobile platforms.

Expertise in channel coding, modulation schemes (e.g., coherent systems), and advanced Digital Signal Processing (DSP) techniques for communications.

Proven ability to lead complex system trade-offs and validation using tools like STK, MATLAB/Simulink, or Zemax.

M.S. or Ph.D. in Electrical Engineering, Aerospace Engineering, or a related field.
