Job description

Role:

Embedded Software Engineer

We are looking for an Embedded Software Engineer to design and develop the flight computers and software stacks that power our satellite missions. You will work on real-time embedded systems across spacecraft subsystems including power, communications, ADCS, thermal, and payload control.

Location:

Ahmedabad, Gujarat, India (On-site)

Employment type:

Full-time

Industry:

Space Technology

About Catalyx Space:

Catalyx Space is building the world's best reentry systems. Our reusable ReX vehicles return payloads from orbit at unprecedented scale, up to 12 tons and 60m³ of cargo, while operating the full mission lifecycle from launch to recovery. Our core innovation is a Origami-inspired deployable heat shield that combines the scalability of an inflatable system with the robustness of a rigid structure. Built from commercial off-the-shelf components, it enables the world's widest heat shields, the largest payload return volumes, and a scalable pathway for returning everything from commercial cargo to future space nuclear assets.

Key responsibilities:

• Architect, implement, and validate embedded software for onboard computers and subsystem controllers


• Develop low-level drivers for sensors, actuators, radios, and communication buses such as I2C, SPI, UART, and CAN


• Implement real-time task scheduling, fault detection, and redundancy mechanisms for mission-critical reliability


• Work closely with avionics hardware engineers for board bring-up, hardware-software integration, and debugging


• Develop communication protocols for satellite telemetry, telecommands, and payload data handling


• Contribute to software-in-the-loop and hardware-in-the-loop test setups for mission validation

Qualifications:

• B.E./B.Tech or M.E./M.Tech in Electronics, Computer Science, Aerospace, or a related field


• 2–6 years of experience in embedded software or firmware development


• Strong proficiency in C/C++ and real-time embedded systems programming


• Experience with bare-metal programming and RTOS such as FreeRTOS or Zephyr


• Strong understanding of digital electronics, microcontrollers, and processor architectures such as ARM Cortex-M/R or RISC-V


• Experience handling FPGAs, including integration with embedded systems and hardware-software co-design


• Familiarity with debugging tools such as JTAG, SWD, logic analyzers, and oscilloscopes


• Proficiency with Git, CI/CD pipelines, and automated testing practices


• Knowledge of fault tolerance, watchdogs, and redundant system design in embedded environments

Nice to have:

• Experience with space-grade or high-reliability systems, including radiation-hardened processors and fault-tolerant software


• Knowledge of satellite communication protocols


• Exposure to ADCS algorithms, sensor fusion, or real-time control systems


• Experience with satellite flight software frameworks or CubeSat missions


• Familiarity with Python or MATLAB for simulation and data analysis


• Understanding of aerospace software standards

Compensation & benefits:

• Competitive salary (details will be shared with shortlisted candidates),


• health insurance


• Provident fund.

Equal Opportunity:

Catalyx Space is an equal opportunity employer and does not discriminate on any protected characteristic.
