The Satcom team is responsible for the design, delivery and performance of Open Cosmos’ satellite communications services, spanning the space segment, ground infrastructure and global connectivity.
As the team continues to scale we are now looking for a Senior Access Layer Engineer who’ll lead the implementation and validation of the satellite air interface, translating high-level architecture into detailed designs, simulations, and working prototypes.
What will you be doing? You’ll play a key role in shaping how waveform generation, MAC protocols, and link adaptation perform within demanding LEO environments by:
- Developing and optimising PHY and MAC layer functionality for satellite communication systems
- Defining and validating random access, scheduling, timing advance, and resource allocation mechanisms
- Designing algorithms to mitigate LEO-specific challenges including Doppler effects, latency, and mobility constraints
- Building and maintaining link-level simulation environments using MATLAB, Simulink, or Python
- Supporting waveform, numerology, and frame structure definition aligned to 3GPP NTN and DVB-S2X standards
- Developing and validating link adaptation strategies including ACM and CSI-driven optimisation
- Defining and governing interface specifications across critical access layer subsystems
- Leading rapid prototyping activities using SDR platforms and system-in-the-loop validation environments
- Designing and executing verification scenarios for mobility, handover, BER, and throughput performance
- Working closely with architects and multidisciplinary engineering teams to bridge system design and implementation
What You’ll bring:
- Strong capability in wireless PHY and MAC layer design within satellite or high-performance communication systems
- Deep understanding of L1/L2 protocols including random access, scheduling, timing advance, and resource allocation
- Strong knowledge of 3GPP NR standards (TS 38.211–38.321) and familiarity with DVB-S2X
- Advanced modelling and simulation capability using MATLAB, Simulink, or Python
- Strong grounding in Digital Signal Processing including synchronisation, forward error correction, and multi-user detection
- Knowledge of waveform design, numerology, and frame structure validation
- Strong understanding of link adaptation techniques including ACM and CSI-driven optimisation
- Familiarity with SDR platforms such as USRP or GNU Radio and rapid prototyping workflows
- Understanding of LEO satellite communication challenges including Doppler, propagation delay, and mobility management
- A highly analytical and structured approach to problem-solving, performance optimisation, and system validation
This role will be based in any of our locations. To apply, you must have the legal right to work in your chosen location. When applying, please submit your CV in English.
