About the job
Mach Industries develops autonomous defense platforms designed to meet the evolving needs of national security. Established in 2022, the company operates with a startup mindset and a team of around 220 professionals. The focus lies in scalable, decentralized systems that strengthen the capabilities of the United States and its allies, with a commitment to advancing manufacturing and accelerating development cycles.
Role overview
The Software Engineer, Localization will work on AI-powered autonomy systems for environments where GPS and other sensors may not be reliable. This position centers on designing and implementing estimation and sensor-fusion algorithms that support robust navigation for multiple products. The work bridges perception, state estimation, and embedded systems, bringing advanced algorithms from research into practical field use.
What you will do
- Develop and productionize vision-based navigation and targeting features, progressing from simulation to Hardware-in-the-Loop (HITL) and flight, using production-level C++.
- Convert detections from EO/IR/RF/radar sensors into precise measurement models, ensuring the estimator remains decision-aware and maintains state integrity.
- Refine GNSS to Visual-Inertial Odometry (VIO) handover by applying adaptive covariances and gating, reducing estimator jumps and resets.
- Create and optimize real-time software for Linux and embedded platforms, analyze CPU/GPU performance, and vectorize key code paths. Familiarity with CUDA or TensorRT on Jetson hardware is beneficial.
- Oversee calibration and time synchronization across IMU, cameras, radar, LiDAR, and GNSS, and validate results during flight tests.
- Build evaluation pipelines and dashboards to monitor drift, handover stability, relocalization, and track quality.
- Implement fault detection and ensure systems handle challenging conditions such as blur, low-light, vibration, or RF denial gracefully.
- Integrate global aids (maps, magnetics, radar) to support long-term consistency and reliability in loop-closure.
