Role Description This is a full-time On-Site role for an Avionics Engineer, located in Hyderabad with some work from home acceptable. The Avionics Engineer will be responsible for designing, developing, and testing avionics systems for aircraft. Daily tasks include systems engineering, aerospace engineering, and electrical engineering related to aircraft systems. The Avionics Engineer will work closely with cross-functional teams to ensure the successful integration and performance of avionics systems in defense applications. Essential Skills for Autonomous Avionics Engineers Deep proficiency in embedded software (C/C++/Python) for flight control, autopilot, communications, and sensor-processing. Solid theoretical background in control theory and its practical application to autonomous flight, including non-linear control. Experience implementing and tuning autonomous navigation algorithms, including waypoint navigation, path planning, obstacle avoidance, and failsafe recovery. Integration skills for avionics subsystems—GPS, IMU, LIDAR, cameras, telemetry, and RF modules—into real-time operating systems and hardware platforms. Hands-on background in simulation tools (MATLAB/Simulink, Gazebo, etc.), hardware-in-the-loop and software-in-the-loop testing, flight stack architectures, and onboard firmware. Familiarity with industry standards (DO-178C, DO-254 for safety/regulatory compliance), avionics cybersecurity, and electromagnetic compatibility (EMC/EMI) testing. Experience with open-source autopilot frameworks (PX4, ArduPilot, ROS), perception systems, and sensor fusion pipelines. Typical Responsibilities Design, implement, and test avionics systems enabling drone autonomy, safety, communication, and real-time decision-making. Build and validate control algorithms, sensor fusion code, and robust flight stack architectures for complex, real-world conditions. Integrate new sensor payloads and develop custom drivers/APIs for hardware and software interoperability. Lead efforts in simulation, flight testing, and debugging to accelerate rapid deployment and iterations of autonomous features. Document compliance artifacts, test plans, and safety evidence to meet airworthiness and regulatory standards.
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.
