Senior Embedded Software Engineer - Flight Software

Ready to make connectivity from space universally accessible, secure, and actionable? Then you’ve come to the right place!

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 New Space 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 areseekinga highly skilled and motivatedFSW/Embedded Software Developer to design, develop, and optimize software for customized embedded devices,with a strong emphasis onspace-related software and algorithms. The role involves designing anddevelopingsoftware forbare-metal,RTOS, and real-time Linux environments, real-time performance, system reliability, and implementing robust recovery mechanisms. You will also contribute totesting and automation.

• Embedded Software Development:
  
  Architect/Design, write, debug, andmaintainefficientsoftware forreal-time embedded systems, including mission critical
  
  Flight Software and communication withotherspace-specific software subsystems/modules, such as TTC (CCSDS protocol), Power, Thermal, GNC, FDIR, CFDP.

• Communication Protocol sand Specifications:
  Implement protocols used inspace-grade software such asUART, CAN,Space Wire,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 andimplementefficientmemory management, process management,software updates,reprogrammingandpower saving modesfor embedded systems.
  
  Experience with multi-board Ethernet fabrics (mesh, ring, or tree topologies) for inter-subsystem communication is a plus.

• Test Framework Development:
  Create andmaintainautomated testing frameworks for embedded systems, includingHIL, SIL, PIL.
• Support:
  Provide support for debugging ofreal-time and critical faults.
• Debugging and Validation:
  Use tools like oscilloscopes, logic analyzers, and protocolanalyzersto test and debug embedded software and hardware interfaces.
• Hardware Interaction:
  Work closely with global software teams to contribute to thenew designsandensure seamless software-hardware integration.
• Documentation:
  Prepare andmaintaintechnical documentation.

• 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 tool chains. Experience with Yocto is a big plus.
• Communication Protocols:
  Knowledge of key hardware…
