About The Position

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—and we’re 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 intentional, we’re unapologetically curious and we’re 100% committed—to saving space, to protecting our planet and to turning connectivity into actionable intelligence. We are 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. The role involves designing and developing software for bare-metal, RTOS, and real-time Linux environments, real-time performance, system reliability, and implementing robust recovery mechanisms. You will also contribute to testing and automation.

Requirements

• Proven record of designing and developing significant working software in aerospace applications.
• Proficiency in C/C++ and scripting languages like Shell or Bash; familiarity with Python.
• Experience with embedded and multicore platforms and their toolchains.
• Knowledge of key hardware and software protocols such as UART, CAN, SPI, I2C. TCP and UDP.
• Experience with secure firmware updates and reprogramming mechanisms.
• Proficiency with debugging tools like JTAG, GDB, and serial debuggers.
• Expertise with Git or similar version control systems.
• 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.
• A willingness to undertake further relevant training.
• An understanding and commitment to equal opportunities.
• Time management, self-reliance and willingness to learn.

Nice To Haves

• Experience with Yocto is a big plus.
• Experience with multi-board Ethernet fabrics (mesh, ring, or tree topologies) for inter-subsystem communication is a plus.
• Bachelor’s or Master’s degree in Computer Science, Electronics Engineering, or a related field.
• 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.

Responsibilities

• 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.
• Implement protocols used in space-grade software such as UART, CAN, SpaceWire, SPI, I2C, and Ethernet.
• 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.
• 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.
• Design and implement efficient memory management, process management, software updates, reprogramming and power saving modes for embedded systems.
• Create and maintain automated testing frameworks for embedded systems, including HIL, SIL, PIL.
• Provide support for debugging of real-time and critical faults.
• Use tools like oscilloscopes, logic analyzers, and protocol analyzers to test and debug embedded software and hardware interfaces.
• Work closely with global software teams to contribute to the new designs and ensure seamless software-hardware integration.
• Prepare and maintain technical documentation.

Benefits

• We may use artificial intelligence (AI) tools to support parts of the hiring process, such as reviewing applications, analyzing resumes, or assessing responses. These tools assist our recruitment team but do not replace human judgment. Final hiring decisions are ultimately made by humans.
