Avionics and Flight Systems Engineer

Company Description We are an Indian Aerospace Startup building next-Generation Autonomous Aerial systems for Defense Applications. We are Developing platforms Designed for speed, precision, and survivability. Role Introduction We’re looking for a Flight Systems Engineer  who can take systems from CAD → bench → simulation → flight — owning embedded avionics, power systems, communication interfaces, and HIL/SITL testing. This is a founding-engineer role  with high ownership, fast iteration, and real impact. Key Responsibilities End-to-End Flight Systems Integration Architect and implement the complete avionics stack: flight controller, companion computer, telemetry, RC link, camera system, PDU, and sensor interfaces . Integrate and validate all onboard sensors (IMU, GNSS, pitot-static, baro, magnetometer, cameras). Ensure accurate sensor time synchronization  and fault-tolerant logging. Implement remote control, assisted, and autonomous modes with smooth transition and fail-safe validation. Develop power architecture  — battery segregation, PDUs, current sensing, grounding, and thermal management. Design EMI/EMC-robust wiring harnesses , grounding layouts, and shielding. Lead hardware bring-up and functional testing of control electronics. Simulation, HIL/SITL, and Validation Develop and maintain Hardware-in-the-Loop (HIL)  and Software-in-the-Loop (SITL)  benches. Create servo/load rigs, thrust stands , and embedded test automation scripts  (Python/MATLAB). Perform bench-level and tethered hover tests , log analysis, and telemetry validation. Work with controls, propulsion, and aerodynamics teams for full system correlation. Analyze flight data to tune control gains and verify stability margins. Software, Communication, and Control Integration Program and configure flight controllers and companion systems  (PX4 / ArduPilot / custom RTOS). Implement CAN, UART, I2C, SPI, and Ethernet  communication protocols for avionics networking. Develop and debug CAN communication scripts  for inter-module data exchange and diagnostics. Interface with GCS software for telemetry, RC, and video feed integration. Deploy embedded software on C / C++ / Python / MATLAB Simulink / ROS2  environments. Optimize real-time performance and thermal reliability under dynamic flight loads. Testing, Safety, and Documentation Develop and execute flight test checklists , safety gates, and acceptance criteria. Maintain ICDs, wiring diagrams, calibration logs, and test reports. Lead ground test campaigns (sensor calibration, thrust mapping, EMI scans, endurance runs). Correlate flight data with simulation results for continuous improvement. Core Skill Set Embedded Hardware & Electronics Proficiency with microcontrollers (STM32, ESP32, NXP, etc.) , RTOS, and low-level board bring-up. Strong understanding of sensors, IMUs, barometers, GNSS, magnetometers , and camera systems. Power system design: PDUs, fusing, current sensors, battery safety , and thermal design. PCB interface and connector-level design familiarity. Communication & Networking CAN / UAVCAN , UART, I2C, SPI, and Ethernet-based avionics communication. Experience with telemetry links, RC systems , and video transmission optimization . EMI/EMC mitigation, grounding, and shielding best practices. Software & Simulation Proficiency in C / C++ / Python / MATLAB / Simulink  for embedded and simulation development. Familiarity with ROS / ROS2  for system integration and visualization. Experience with HIL/SITL setup , Gazebo/JSBSim, or PX4/ArduPilot test environments. Data analysis and visualization using Python (NumPy, Pandas, Matplotlib). Testing & Validation Skilled in hardware test bench design , sensor calibration, and system diagnostics. Knowledge of flight log analysis , control tuning, and telemetry validation. Ground and flight test instrumentation setup and data correlation. Qualifications & Experience B.E/B.Tech or M.E/M.Tech  in Electronics, Electrical, Mechatronics, Aerospace, or Robotics Engineering . Experience:  3–5 years in flight systems, avionics, or embedded engineering. Hands-on background with UAVs, drones, or aerospace/defense-grade systems preferred. Proven ability to take hardware/software systems from prototype to validated flight. Preferred Extras Companion computer integration (NVIDIA Jetson, Raspberry Pi). Visual odometry, SLAM, or GNSS-denied navigation systems. Contributions to open-source flight stacks or embedded projects. How to Apply Resume (PDF) Portfolio / repo / project links (hardware photos, firmware, flight logs) Optional: 2–3 lines on the most challenging flight system problem you solved. Why Join Us  You’ll design and integrate systems that actually fly. Founding-level ownership and technical leadership. Work on the frontier of real-world autonomy and flight systems
