LEO Satellite Air Interface Architect

Open Cosmos; Porto; Presencial; EUR 90 000 - 150 000; Tempo integral

Resumo da oferta

Open Cosmos is seeking an Air Interface Architect to define and govern the PHY/MAC architecture for our LEO satellite system. You will shape high-performance, scalable connectivity across the constellation and drive end-to-end design from waveform to MAC protocols.

Ideal candidates have deep wireless knowledge, 3GPP NTN familiarity, and experience modelling orbital dynamics to robust air interface specs. Role available at multiple locations.

Qualificações

• Strong background in wireless systems and PHY/MAC architecture.
• Deep knowledge of 3GPP NR NTN standards and DVB-S2X familiarity.
• Experience translating orbital dynamics into air interface specs.

Responsabilidades

• Define end-to-end L1/L2 architecture for satellite comms per 3GPP NTN and DVB-S2X.
• Translate Doppler, latency, beam movement and visibility into requirements.
• Drive waveform, numerology, frame structure and resource allocation design.
• Define coding, modulation and link adaptation strategies across links.
• Architect MAC protocols including scheduling and HARQ/ARQ.
• Define mobility and handover across satellites, gateways and terminals.
• Specify synchronisation and timing/frequency pre-compensation strategies.
• Support integration with core network functions for NTN connectivity.
• Lead system- and link-level modelling and simulation for validation.
• Define modem architecture across FPGA/ASIC and software layers for multi-waveform support.
