GNSS-Denied Navigation & State Estimation Engineer

Archer; San Jose (CA); On-site; USD 140,000 - 260,000; Full time

Job summary

Archer is an aerospace company based in San Jose, California building an all-electric vertical takeoff and landing aircraft with a mission to advance sustainable air mobility. This onsite role supports developing navigation and state-estimation for GPS-denied environments.

You will develop and tune state-estimation algorithms, implement VIO/SLAM, fuse IMU, camera and lidar data, and validate performance across simulation and field tests.

Qualifications

• Background in GN&C, robotics or a related technical field.
• Strong proficiency in C++ and Python.
• Experience with VIO/SLAM techniques.
• Experience with EKF or factor-graph-based sensor fusion.
• Experience integrating IMU, camera, and lidar sensors into a navigation stack.

Responsibilities

• Develop and tune state-estimation algorithms for GPS-denied and GNSS-degraded navigation.
• Implement visual-inertial odometry (VIO), lidar/vision-aided INS, and multi-sensor fusion approaches.
• Integrate state-estimation solutions with onboard sensors (IMU, camera, lidar).
• Validate navigation performance through simulation, bench testing, and field testing.
• Analyze test data to identify and resolve navigation performance issues.
• Collaborate with perception, controls, and test teams to ensure robust navigation.
