Embedded Software Engineer

Job Summary:

We are looking for a driven and technically sound Embedded Software Engineer to join the Avionics department. The selected candidate will be responsible for developing and maintaining real-time embedded firmware for satellite and launch vehicle avionics systems, including payload interfaces, onboard data handling units, communication modules, and telemetry systems. You will work on mission-critical systems that demand high reliability, low power operation, and fault tolerance under harsh space environments.

Roles & Responsibilities:

• Design, develop, and test embedded firmware for satellite avionics subsystems including OBDH (Onboard Data Handling) , TMTC , power control , sensor interfaces , and payload controllers .
• Implement firmware for interfacing with radiation-hardened microcontrollers , sensors , memory modules , and communication buses .
• Develop and optimize real-time routines for telemetry data handling , telecommand parsing , health monitoring , and autonomous system control .
• Write device drivers and interface logic for SPI, I2C, UART, CAN, RS-422 , and SpaceWire protocols.
• Support board bring-up , system integration, and flight hardware testing.
• Work with hardware and systems teams to define firmware architecture and interface specifications.
• Ensure compliance with space-grade development standards (e.g., ECSS , DO-178C , or equivalent).
• Participate in unit testing , HIL testing , and end-to-end validation for mission readiness.
• Document code, design rationale, test results, and interface definitions.

Skills Required:

Technical Skills:

• 25 years of experience in embedded firmware development , preferably in satellite, defence or aerospace domain .
• Strong experience in Embedded C/C++ programming for real-time systems.
• Hands-on experience with RTOS (FreeRTOS, RTEMS, RTLinux or custom schedulers).
• Hands-on development experience with using microcontrollers and microprocessors - STM32, Zynq SoCs, Zynq Ultrascale, RF SoC, etc.
• Experience with embedded communication interfaces : UART, SPI, I2C, CAN, RS-422 and Ethernet.
• Expertise in low-level firmware development , bootloaders, and interrupt-driven architectures.
• Good understanding of Avionics Software , fault detection , and redundancy logic .
• Experience with hardware debugging tools: oscilloscopes , JTAG/SWD , logic analyzers , etc.
• Excellent data analysis, Problem solving, and decision-making skills
• Use version control systems (GIT) and Application management tools (Jira,Polarian,IBM Rational) for effective workflow management.
• Familiarity with static analysis tools.

Desirable / Bonus Skills:

• Exposure to radiation-tolerant design practices and watchdog/time supervision strategies.
• Familiarity with space communication protocols like CCSDS, SpaceWire, or MIL-STD-1553.
• Familiarity with space-qualified microcontrollers , SoCs, and memory devices (NOR/NAND Flash, MRAM, EEPROM).
• Experience with flight software simulators , automated test benches , or scripting with Python/Bash .
• Working knowledge of power management , thermal control , or payload interfacing .
• Prior experience with space missions, satellite bus systems , or payload control systems is a strong plus.

Soft Skills:

• Strong analytical and debugging skills.
• Clear verbal and written communication for technical documentation and cross-functional coordination.
• Attention to detail with a strong sense of ownership and quality consciousness.
• Ability to work in fast-paced, high-reliability, and schedule-driven space missions.

Experience & Qualification:

• B.E/B.Tech or M.E/M.Tech in Electronics , Electrical , Computer Science , Aerospace , or Embedded Systems Engineering .
