• Translate system requirements into robust embedded system architectures, including partitioning across MCU/FPGA/ASIC and software.
• Select suitable components (MCUs/SoCs, ADC/DACs, clocks, power, memories) and define interfaces to implement the architecture.
• Design and integrate interfaces to digital (e.g. telemetry/telecommand buses) and analog (e.g. Photodiodes) peripherals and components.
• Develop high-throughput digital signal processing units for real-time acquisition, filtering and processing of digital data streams.
• Develop embedded software (C/C++ on bare-metal and/or RTOS), including boot, drivers, middleware, and application logic.
• Collaborate closely with FPGA, hardware, and optical engineering teams to deliver complex quantum-cryptography solutions.
• Create documentation: requirements, interface control documents, design specs, and verification plans.
• Establish quality practices: code reviews, static analysis, unit/integration testing, and CI for firmware.
• Contribute to system security, reliability, EMC/EMI, and DfX considerations throughout the lifecycle.

• Strong track record designing embedded architectures from requirements through production.
• Knowledge of MCU/SoC/SoM platforms, RTOS concepts, memory/clocking, and low-level drivers.
