Embedded System Engineer

Embedded Systems Engineer – UAV & Jet Propulsion SystemsLocation:Hyderabad (On Site) Company:Apollyon Dynamics Type:Full-Time About Apollyon DynamicsApollyon Dynamics is aBITS Pilani, Hyderabadstudent-led defense technology startup buildingnext-generation UAV systems, fromjet-propelled loitering munitionstoautonomous aerial platformsthat redefine speed, endurance, and intelligence. Our mission is to fusecutting-edge avionics, AI-driven control, and indigenous manufacturingto power India’s next era of defense innovation. We’re young, ambitious, and deeply technical, if you’ve ever wanted tobuild something that actually flies, this is your place.Role OverviewWe’re looking for anEmbedded Systems Engineerwho can turn control theory and aerodynamics into working hardware. You’ll be responsible for developingreal-time embedded firmwarethat drives propulsion, control surfaces, and sensor systems for our UAV platforms. This isn’t a maintenance role — it’s anR&D-heavy engineering positionwhere you’ll be prototyping, testing, and debugging firmware that powersautonomous jet UAVs. You’ll work directly with theaerodynamics,control systems, andAI autonomyteams to ensure tight hardware–software integration.Key ResponsibilitiesDesign, develop, and optimizeembedded firmwarefor UAV flight controllers and propulsion subsystems. Integratesensors(IMU, GPS, barometer, pitot tube, fuel/temperature sensors) andactuators(ESCs, servos, jet throttle valves). Implement and tunecontrol loops (PID, LQR, custom algorithms)in real-time environments. Develop and maintaincommunication protocols— UART, SPI, I2C, CAN, andMAVLinkfor telemetry. Bring up and debugSTM32-basedboards, 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. Conductbench testing and field testingof avionics systems with data logging and analysis. Maintain documentation for firmware architecture, APIs, and hardware interfacing. Required Skills & ExperienceCore Firmware:Strong C++ 17 for embedded systems, familiarity withSTM32 / ARM Cortexmicrocontrollers RTOS / Bare Metal:Experience withFreeRTOS, 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, andMAVLinkfor 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 familiarityBonus:PX4/Ardupilot firmware experience, ROS2, UAVCAN, sensor fusion (EKF), MATLAB/Simulink, embedded LinuxNice-to-Have ExperiencePrior work onUAVs, drones, or roboticsplatforms Experience flashing and debugging PX4 or Ardupilot builds Knowledge ofcontrol systems, signal processing, or state estimation Comfort withGazeboorPX4 SITLsimulation environments Experience withAI-on-edgeor microcontroller-based ML inferencePersonality & Culture FitWe’re not looking for employees; we’re looking forbuilders. You’ll fit right in if you: Thrive inhands-on R&D, not just documentation. Enjoydebugging at 2 AMbecause you just got a new sensor talking. Want to see your code take flight – literally. Are comfortable working in afast-paced, mission-drivenstartup environment. Believe in learning fast, failing smart and fast, and iterating even faster.
