Embedded Systems Engineer – UAV & Jet Propulsion Systems

Location:

Hyderabad (On Site)

Company:

Apollyon Dynamics

Type:

Full-Time

About Apollyon Dynamics

Apollyon Dynamics is a
BITS Pilani, Hyderabad

student-led defense technology startup building
next-generation UAV systems

, from
jet-propelled loitering munitions

to
autonomous aerial platforms

that redefine speed, endurance, and intelligence.

Our mission is to fuse
cutting-edge avionics, AI-driven control, and indigenous manufacturing

to power India's next era of defense innovation.

We're young, ambitious, and deeply technical, if you've ever wanted to
build something that actually flies

, this is your place.

Role Overview

We're looking for an
Embedded Systems Engineer

who can turn control theory and aerodynamics into working hardware.

You'll be responsible for developing
real-time embedded firmware

that drives propulsion, control surfaces, and sensor systems for our UAV platforms.

This isn't a maintenance role — it's an
R&D-heavy engineering position

where you'll be prototyping, testing, and debugging firmware that powers
autonomous jet UAVs

.

You'll work directly with the
aerodynamics

,
control systems

, and
AI autonomy

teams to ensure tight hardware–software integration.

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:

PX4/Ardupilot firmware experience, ROS2, UAVCAN, sensor fusion (EKF), MATLAB/Simulink, embedded Linux

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

We're not looking for employees; we're looking for
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.
