About Apollyon Dynamics

BITS Pilani, Hyderabad

cutting-edge avionics, AI-driven control, and indigenous manufacturing

We’re young, ambitious, and deeply technical, if you’ve ever wanted to build something that actually flies, this is your place.

Role Overview

Embedded Systems Engineer

real-time embedded firmware

R&D-heavy engineering position

aerodynamics

Key Responsibilities

• Design, develop, and optimize

  embedded firmware

  for UAV flight controllers and propulsion subsystems.
• Integrate

  sensors

  (IMU, GPS, barometer, pitot tube, fuel/temperature sensors) and

  actuators

  (ESCs, servos, jet throttle valves).
• Implement and tune

  control loops (PID, LQR, custom algorithms)

  in real-time environments.
• Develop and maintain

  communication protocols

  — UART, SPI, I2C, CAN, and

  MAVLink

  for telemetry.
• Bring up and debug

  STM32-based

  boards, ensuring robust RTOS performance (FreeRTOS or NuttX).
• Collaborate with control engineers to deploy algorithms from MATLAB/Simulink or Python simulations to the microcontroller.
• Ensure system reliability — watchdogs, fault handling, and real-time safety checks.
• Conduct

  bench testing and field testing

  of avionics systems with data logging and analysis.
• Maintain documentation for firmware architecture, APIs, and hardware interfacing.

Required Skills & Experience

• Core Firmware:

  Strong C++ 17 for embedded systems, familiarity with

  STM32 / ARM Cortex

  microcontrollers

• RTOS / Bare Metal:

  Experience with

  FreeRTOS

  , thread scheduling, interrupt handling, and low-level drivers

• Electronics:

  Understanding of digital electronics, ADC/DAC, PWM, serial communication, and PCB-level debugging

• Communication Protocols:

  UART, SPI, I2C, CAN, and

  MAVLink

  for UAV telemetry

• Sensor Integration:

  IMUs, GPS, barometers, magnetometers, ESCs, and other avionics components

• Control Loops:

  Basic understanding of PID control and ability to implement it on hardware

• Testing Tools:

  Logic analyzers, oscilloscopes, serial monitors, data loggers

• Version Control:

  Git / GitHub workflow familiarity

Bonus:

Nice-to-Have Experience

• Prior work on

  UAVs, drones, or robotics

  platforms
• Experience flashing and debugging PX4 or Ardupilot builds
• Knowledge of

  control systems

  , signal processing, or state estimation
• Comfort with

  Gazebo

  or

  PX4 SITL

  simulation environments
• Experience with

  AI-on-edge

  or microcontroller-based ML inference
  

Personality & Culture Fit

builders

You’ll fit right in if you:

• Thrive in

  hands-on R&D

  , not just documentation.
• Enjoy

  debugging at 2 AM

  because you just got a new sensor talking.
• Want to see your code take flight – literally.
• Are comfortable working in a

  fast-paced, mission-driven

  startup environment.
• Believe in learning fast, failing smart and fast, and iterating even faster.
