Samtel Avionics Limited

Role: Software Developer

Employment Type: Full Time

Location: Gurugram, India

Educational Qualification: BE/BTech/ M.Tech / MS in Software Engineer

Work Experience: 6-8+ years of relevant work experience

Role Description:

Design and develop software for satellite systems, including onboard flight software and ground segment applications, ensuring reliability and real-time performance. Collaborate with hardware, AOCS, and mission teams to implement, test, and integrate software across the mission lifecycle. Support verification, validation, and in-orbit operations for robust and mission-critical performance.

Responsibilities & Duties:

• Design, develop, and maintain onboard flight software (FSW) and ground segment applications for satellite missions
• Develop real-time, embedded software for spacecraft subsystems (AOCS, EPS, payload, communication)
• Implement software in languages such as C/C++, Python, and embedded C for high-reliability systems
• Design software architecture, modules, and interfaces aligned with system requirements and mission objectives
• Develop drivers and low-level firmware for hardware interfaces (SPI, I2C, UART, CAN, SpaceWire, Ethernet)
• Work with real-time operating systems (RTOS) such as FreeRTOS or equivalent
• Implement communication protocols for telemetry, telecommand, and data handling
• Collaborate with hardware, AOCS, RF, and systems teams for seamless hardware-software integration
• Develop simulation tools, test scripts, and automation frameworks using Python or MATLAB
• Perform software verification and validation (V&V), including unit testing, integration testing, and system testing
• Develop and execute Software-in-the-Loop (SIL) and Hardware-in-the-Loop (HIL) test environments
• Perform code reviews, static analysis, and debugging to ensure reliability and performance
• Optimize software for real-time performance, memory usage, and fault tolerance
• Implement fault detection, isolation, and recovery mechanisms
• Support integration, system testing, and environmental testing (EMI/EMC, thermal vacuum, vibration)
• Develop and maintain technical documentation (design documents, interface control documents, test reports)
• Participate in design reviews (SRR, PDR, CDR, TRR) and technical discussions
• Support launch operations, commissioning, and in-orbit software updates and anomaly resolution
• Utilize version control and collaboration tools such as Git
• Work within structured development processes (Agile/Waterfall/Sprint) and configuration management systems
• Troubleshoot software and system-level issues and perform root cause analysis

Desirable Skills & Certifications:

• Strong proficiency in C/C++ and Python for embedded and system-level software development
• Experience with real-time operating systems such as FreeRTOS or equivalent RTOS platforms
• Familiarity with spacecraft communication protocols (UART, SPI, I2C, CAN, SpaceWire, Ethernet) and telemetry/telecommand systems
• Experience in Software-in-the-Loop (SIL), Hardware-in-the-Loop (HIL), and simulation-based verification
• Knowledge of space software standards and practices (ECSS, NASA, ISRO, MISRA C guidelines)
• Proficiency in version control and development workflows using Git and CI/CD practices
• Understanding of embedded systems, firmware development, and hardware-software integration
