Software Engineer, Localization

Mach Industries•Huntington Beach, CA

About The Position

Founded in 2022, Mach Industries is a rapidly growing defense technology company focused on developing next-generation autonomous defense platforms. At the core of our mission is the commitment to delivering scalable, decentralized defense systems that enhance the strategic capabilities of the United States and its allies. With a workforce of approximately 220 employees, we operate with startup agility and ambition. Our vision is to redefine the future of warfare through cutting-edge manufacturing, innovation at speed, and unwavering focus on national security. We are dedicated to solving the next generation of warfare with lethal systems that deter kinetic conflict and protect global security. Mach Industries is building an AI‑forward autonomy stack for contested environments where GPS and other sensing is unavailable or unreliable. As an member of our team, you will design and implement state-of-the-art estimation and sensor-fusion algorithms that power robust navigation across all of our product lines. You will work at the intersection of perception, state estimation, and embedded systems to bring research-grade algorithms to rugged, real-world deployments.

Requirements

Stellar software ability: Modern C++ on Linux; Python for tooling/analysis; strong debugging, profiling, testing discipline.
SLAM/state estimation: Error-state EKF/UKF, factor graphs, nonlinear least-squares (Ceres/GTSAM), observability and covariance tuning.
Vision experience VIO/SLAM, camera models, optical flow/feature tracking; comfort with deep learning for detection/seg/pose (PyTorch) and on-edge deployment.
Sensor integration: IMU strapdown and biases, GNSS/RTK; multi-camera, LiDAR, radar, magnetometer, barometer.
Ship and fly: Proven research-to-production delivery and field testing on real platforms.
5 years of experience with either a BS/MS/PhD in Computer Science, Robotics, Electrical/Aerospace Engineering, or related field, or equivalent practical experience.

Nice To Haves

Experience with CUDA/TensorRT/ONNX Runtime; NVIDIA Jetson pipelines.
Exposure to ROS 2, PX4/ArduPilot integration
Strong data practices: data validation in CI, SQL/Parquet, reproducible datasets.
Experience in contested/denied RF, low-light/night, high-vibration environments.
Rust for systems tooling; Docker for reproducibility.

Responsibilities

Prototype and productionize vision navigation and targeting features end-to-end from sim to HITL to flight with production C++.
Turn detections (EO/IR/RF/radar) into well-posed measurement models with latencies/covariances; make the estimator decision‑aware without corrupting state.
Stabilize GNSS to VIO handover (adaptive covariances, gating, hysteresis, reset‑less alignment) to eliminate jumps and estimator resets.
Build and optimize real-time software on Linux/embedded; profile CPU/GPU, vectorize hot paths; optional CUDA/TensorRT on Jetson hardware.
Own calibration and time-sync across IMU/cameras/radar/LiDAR/GNSS; validate in flight.
Create evaluation pipelines and dashboards for drift, handover stability, relocalization, track quality
Implement fault detection and graceful degradation for harsh conditions (blur, low‑light, vibration, RF denial).
Integrate global aids (maps, magnetics, radar) for long‑term consistency and loop‑closure robustness.
