Role Objective
We are seeking a Mid-Senior PX4 Firmware Developer with 3–5 years of experience to design and optimize the flight control architecture for a high-performance, long-range UAV platform. You will lead the implementation of robust, real-time software that enables autonomous operations in GNSS-denied and contested environments. This role sits at the intersection of embedded systems and advanced GNC, requiring a developer who can translate complex control laws into deterministic, flight-ready code.
Key Responsibilities
- Firmware Development: Architect and maintain custom modules within the PX4 Autopilot ecosystem, focusing on high-reliability and low-latency execution.
- GNC Implementation: Collaborate with GNC engineers to implement Advanced Guidance Laws (e.g., Proportional Navigation variants) and custom flight modes for autonomous mission phases.
- Middleware & Communication: Design and optimize the communication bridge between the flight controller and companion computers using micro-XRCE-DDS and ROS 2.
- Navigation Resilience: Modify and tune the PX4 EKF2/EKF3 to incorporate External Vision and Terrain-Referenced Navigation (TRN) updates for position resetting in GPS-denied areas.
- Sensor Fusion: Integrate and calibrate high-grade aerospace sensors, including Industrial IMUs, Air Data Systems, and specialized altimetry.
- Offboard Autonomy: Develop sophisticated logic for Offboard Mode to enable seamless transitions between manual, semi-autonomous, and fully autonomous flight profiles.
- Validation & Testing: Lead SITL/HITL simulation efforts using Gazebo/Ignition to validate flight logic and failure handling before real-world deployment.
Required Skills & Qualifications
- Experience: 3–5 years in embedded firmware, with a minimum of 2 years dedicated to the PX4 Autopilot stack and NuttX RTOS.
- Programming: Expert proficiency in C++11/14/17 for resource-constrained environments and Python for automation.
- Architecture: Deep understanding of uORB messaging, MAVLink protocol, and PX4 driver development.
- Control Theory: Solid grasp of PID control, state estimation, and Kalman Filtering as applied to fixed-wing or high-speed UAV dynamics.
- Middleware: Hands-on experience with ROS 2 (Humble/Foxy) and DDS-based communication layers.
- Debugging: Advanced skills with JTAG, GDB, and logic analyzers for low-level troubleshooting.
Preferred Qualifications
- Experience working directly with GNC teams or control system engineers
- Experience with fixed-wing UAVs (especially tuning and navigation)
- Familiarity with EKF2/EKF3 and state estimation tuning
- Experience in SITL/HITL simulation (Gazebo, JMAVSim)
- Knowledge of ROS/ROS2 integration
- Understanding of aerospace dynamics and flight mechanics
- Experience working on mission-critical or defense-grade systems
- Exposure to DSMAC or vision-based navigation systems
Compensation & Benefits
- Competitive salary based on experience
- Opportunity to work on advanced UAV systems
- Exposure to cutting-edge aerospace and autonomy technologies
Personal Attributes
- Self-starter with a keen sense of initiative and ownership.
- Collaborative team player who enjoys working in a dynamic environment.
- Detail-oriented and able to manage multiple projects simultaneously.
- Passion for drones and unmanned aerial technology.
Working Conditions
- This is a full-time position based in Bangalore, India that may require occasional evening or weekend work.
- May require travel to customer sites or other company locations.
Salary And Benefits
- Competitive salary based on experience and qualifications.
- Health insurance.
- Paid time off and holidays.
- Opportunities for professional development and growth.
