Function: Embedded Software, Flight Software, C&DH

Project-S is looking for an Embedded Flight Software & C&DH Engineer to develop onboard software for satellite missions. You will help define how the spacecraft boots, handles commands, generates telemetry, manages modes, stores data, protects itself from faults, and supports mission operations.

• Develop flight software for onboard computers and subsystem interfaces.
• Implement command handling, telemetry, event logging, health monitoring, command scheduling, time synchronization, and mode management.
• Implement spacecraft modes such as boot, safe mode, detumble, nominal operation, payload operation, downlink, low-power mode, and anomaly recovery.
• Interface with EPS, payload, AOCS/ADCS, TT&C radio, storage, deployment sensors, watchdogs, GPIO lines, and EGSE.
• Implement FDIR logic, watchdog handling, resets, power cycling, safe-state behaviour, and subsystem recovery.
• Build SIL, PIL, HIL, Flat Sat, automated test, and EGSE-connected test environments.

• Strong embedded software skills in C/C++, Rust, or similar, with Python for tooling and automation.
• Experience with RTOS, embedded Linux, bare-metal firmware, microcontrollers, SoCs, or onboard computers.
• Experience with UART, SPI, I2C, CAN, RS-422/RS-485, Ethernet, GPIO, ADC, PWM, PPS, watchdogs, and interrupt-driven systems.
• Understanding of C&DH, onboard storage, packetization, telemetry, data integrity, and downlink preparation.
• Good working practices with Git, CI/testing, logging, release control, configuration control, and reproducible builds.
