About the role

As an Embedded Software Engineer on our Flight Avionics team, you will own the firmware development of our Time-Sensitive Networking (TSN) switch built around a deterministic Ethernet switch IC. Your work will directly influence the safety and reliability of flight control communications – where every microsecond counts.

What you'll do

  • Develop, bring up, and maintain Linux kernel and user-space drivers for deterministic Ethernet switch ICs, including MDIO, SPI, and vendor Switch API integration
  • Implement and validate IEEE 802.1Qbv (Time-Aware Shaper) and IEEE 802.1AS (gPTP) to achieve deterministic, sub-microsecond forwarding for flight-critical frames
  • Architect and tune packet switching fabric for guaranteed real-time latency across multi-port TSN topologies used in flight control bus architectures
  • Implement high-availability redundancy schemes (HSR / PRP) to ensure seamless failover in dual-ring and parallel-path network configurations
  • Write, automate, and execute longevity and stress tests using Python, Shell, and Tcl/Expect scripting across embedded hardware targets

What you need

  • 5–10 years in electrical & electronics
  • Python
  • C
  • Embedded C
  • Linux
  • TCP/IP
  • Test automation
  • B.Tech or B.E.
