Principal Quantum Security Systems Engineer

Description:

At SRAUT, you will lead, design, integrate the quantum communication subsystem inside our Next Gen NTN satellite payload. This includes developing QKD systems & integrating the architecture that secures satellite communications at a global scale.

You will work closely with our:

Regenerative baseband / onboard gNB team

FPGA/ASIC & SoC teams

Mission & systems engineering teams

Satellite security architecture team

Your work will directly shape the next generation satellites secured by space-grade quantum cryptography.

Key Responsibilities

Architect and develop satellite-based QKD systems (BB84, E91, MDI-QKD, CV-QKD).

Define requirements for detectors, modulators, and subsystems.

Support design of front-end: beam steering, alignment & acquisition.

Model QKD performance (key rates, QBER, atmospheric loss, orbital geometry).

Develop QKD post-processing algorithms: sifting, error correction, privacy amplification.

Integrate QKD keys with onboard 6G gNB security (PDCP, RRC, SDAP).

Interface QKD with classical control channels and inter-satellite optical links.

Contribute to flight hardware architecture, laboratory prototyping, and environmental validation.

Required Skills & Experience

Strong background in quantum communications.
