About the role

Ready to make connectivity from space universally accessible, secure, and actionable?
You will also contribute to testing and automation.
Configure and debug L2 redundancy protocols (RSTP, HSR, FRER) for fault-tolerant fabrics.

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.
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.
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.
Design and implement L2 Ethernet networks for inter-board communication on spacecraft, including switch bring up, PHY configuration, and topology design.
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.
Provide support for debugging of real-time and critical faults.
Prepare and maintain technical documentation.

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
Proficiency in C/C++ and scripting languages like Shell or Bash
familiarity with Python.
Knowledge of key hardware and software protocols such as UART, CAN, SPI, I2C.
Experience with secure firmware updates and reprogramming mechanisms.
Familiarity with wireless communication technologies (e.g., Wi-Fi, Bluetooth, Zigbee, LoRa).
Familiarity with hardware simulation tools and flatsat environments for testing.
Ability to work collaboratively in cross-functional and global teams.

Experience with multi-board Ethernet fabrics (mesh, ring, or tree topologies) for inter-subsystem communication is a plus.
Experience with embedded and multicore platforms and their toolchains.
Experience with Yocto is a big plus.

Proficiency with debugging tools like JTAG, GDB, and serial debuggers.
Use tools like oscilloscopes, logic analyzers, and protocol analyzers to test and debug embedded software and hardware interfaces.
Collaboration and Documentation

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 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.
