Embedded Systems Engineer — Autopilot

EndureAir Systems Pvt Ltd; Dadri; On-site; INR 1,500,000 - 2,300,000; Full time

Job summary

EndureAir Systems Pvt Ltd in Noida is seeking a firmware engineer to develop real-time, safety-critical software for flight subsystems running on ARM Cortex-M microcontrollers.

You will implement sensor interfaces, redundancy and failsafe behavior, build HIL rigs and automated tests, and debug at the hardware boundary with oscilloscopes and logic analyzers, collaborating with controls and operations teams.

Qualifications

• 3+ years writing embedded C/C++ for real-time systems.
• Experience with IMU, GNSS, barometer, magnetometer via I2C/SPI/UART.
• Knowledge of RTOS concepts, interrupt latency, memory-constrained design.

Responsibilities

• Develop real-time firmware for flight-critical subsystems on ARM Cortex-M targets.
• Implement sensor fusion, redundancy management, and failsafe behaviour.
• Build the HIL rigs and automated tests to catch regressions before they reach an airframe.
• Debug at the hardware boundary using a logic analyzer, oscilloscope, and flight logs.
• Support integration and flight test alongside the controls and operations teams.

About the role

Our aircraft fly for defence, utility, and relief operators. Firmware here is safety-critical, and it is reviewed and tested like it.

What you will do

• Develop real-time firmware for flight-critical subsystems on ARM Cortex-M targets.
• Implement and verify sensor fusion, redundancy management, and failsafe behaviour.
• Build the HIL rigs and automated tests that catch regressions before they reach an airframe.
• Debug at the hardware boundary - logic analyser, oscilloscope, and flight logs.
• Support integration and flight test alongside the controls and operations teams.

What we are looking for

• Degree in Electronics, Computer Engineering, or a related field.
• Three or more years writing embedded C or C++ for real-time systems.
• Working knowledge of RTOS concepts, interrupt latency, and memory-constrained design.
• Experience with sensor interfaces - IMU, GNSS, barometer, magnetometer - over I2C, SPI, and UART.
• Comfort reading schematics and debugging on real hardware.

Nice to have

• Prior UAV or avionics work.
• Experience with DO-178C or a comparable assurance process.
• Contributions to an open-source autopilot project.
