Senior Embedded Software Engineer - Flight Software

About the role

At E-Space, we’re focused on bridging Earth and space with the world’s most sustainable low Earth orbit (LEO) satellite network. We’re a team of bold thinkers, ambitious leaders, and dynamic doers disrupting NewSpace by fundamentally changing the design of legacy LEO space systems to deliver entirely new satellite capabilities at a fraction of the cost. We’re seeking a highly skilled and motivated FSW/Embedded Software Developer to design, develop, and optimize software for customized embedded devices, with a strong emphasis on space-related software and algorithms.

Responsibilities

• Core Development
  • Embedded Software Development: Architect, design, write, debug, and maintain efficient software for real-time embedded systems, including mission-critical Flight Software and communication with other space-specific software subsystems/modules, such as TTC (CCSDS protocol), Power, Thermal, GNC, FDIR, CFDP.
  • Communication Protocols and Specifications: Implement protocols used in space-grade software such as UART, CAN, SpaceWire, SPI, I2C, and Ethernet. Experience with Linux bridging, DSA (Distributed Switch Architecture), and L2 protocols such as RSTP/MSTP, HSR, or FRER for redundant network fabrics is highly valued.
  • Networking and Avionics Fabrics: Design and implement L2 Ethernet networks for inter-board communication on spacecraft, including switch bring-up, PHY configuration, and topology design. Configure and debug L2 redundancy protocols (RSTP, HSR, FRER) for fault-tolerant fabrics. Implement deterministic networking using TSN features where mission profiles require bounded latency.
  • Application Integration: Integrate and manage provided applications on top of the customized platform software. Design and bring up Ethernet-based avionics networks, including PHY/MAC initialization, switch configuration, and L2 redundancy protocols.
  • Operational Management: Design and implement efficient memory management, process management, software updates, reprogramming, and power-saving modes for embedded systems. Experience with multi-board Ethernet fabrics (mesh, ring, or tree topologies) for inter-subsystem communication is a plus.
• Testing and Support
  • Test Framework Development: Create and maintain automated testing frameworks for embedded systems, including HIL, SIL, PIL.
  • Support: Provide support for debugging real-time and critical faults.
  • Debugging and Validation: Use tools like oscilloscopes, logic analyzers, and protocol analyzers to test and debug embedded software and hardware interfaces.
• Collaboration and Documentation
  • Hardware Interaction: Work closely with global software teams to contribute to new designs and ensure seamless software-hardware integration.
  • Documentation: Prepare and maintain technical documentation.

Requirements

• Hands-on: Proven record of designing and developing significant working software in aerospace applications.
• Programming Languages: Proficiency in C/C++ and scripting languages like Shell or Bash; familiarity with Python.
• Embedded Systems: Experience with embedded and multicore platforms and their toolchains. Experience with Yocto is a big plus.
• Communication Protocols: Knowledge of key hardware and software protocols such as UART, CAN, SPI, I2C, TCP, and UDP.
• Upgrades: Experience with secure firmware updates and reprogramming mechanisms.
• Debugging Tools: Proficiency with debugging tools like JTAG, GDB, and serial debuggers.
• Version Control: Expertise with Git or similar version control systems.

Qualifications

• Bachelor’s or Master’s degree in Computer Science, Electronics Engineering, or a related field.

Skills

• Familiarity with wireless communication technologies (e.g., Wi-Fi, Bluetooth, Zigbee, LoRa).
• Familiarity with hardware simulation tools and flatsat environments for testing.
• Familiarity with CI/CD pipelines and automated build/test workflows.
• Strong analytical and debugging skills.
• Passion for quality and attention to detail in software development and testing.
• Ability to work collaboratively in cross-functional and global teams.
• Commitment to staying updated with the latest in IoT, embedded systems, and testing automation technologies.
• Willingness to undertake further relevant training.
• Understanding and commitment to equal opportunities.
• Time management, self-reliance, and willingness to learn.
