SiMa.ai; San Jose (CA); On-site; USD 121,000 - 193,000; Full time

Job summary

SiMa.ai in San Jose, CA seeks a Sr. UAV Autonomy Engineer to build the core drone stack for GPS-denied navigation, docking and perception on embedded hardware.

You will own the autonomy stack, optimize for SWaP, and drive real-world flight testing with camera-IMU calibration and SIL/HIL rigs. Requirements include 5+ years in autonomy software on real aircraft, expertise in VIO/SLAM, multi-sensor fusion, ROS 2, C++/Python, and a BS/MS in Robotics, Aerospace, CS, or EE.

Qualifications

• Flight experience building autonomy software on real aircraft (5+ years) and MAVLink experience.
• Expertise in VIO/SLAM, multi-sensor fusion, state estimation, and closed-loop control.
• Strong C++, Python, ROS 2 skills and solid 3D geometry and rigid-body dynamics.
• BS or MS in Robotics, Aerospace, CS, or EE.

Responsibilities

• Develop core drone autonomy stack including navigation, perception and planning.
• Implement GPS-denied navigation, autonomous docking and precision landing.
• Optimize edge deployment for embedded hardware under power/weight limits.
• Lead tests: camera-IMU calibration, SIL/HIL rigs, and flight testing.

Job Description

About SiMa.ai:

SiMa.ai builds power-efficient edge AI chips and autonomy software for drones and robots. Our Modalix MLSoC and ONE Platform enable full perception and autonomy within strict SWaP (size, weight, and power) constraints.

About the role:

We are seeking a hands-on UAV Autonomy Engineer to build the core of SiMa’s drone stack. You will own GPS-denied navigation and autonomous docking, developing the perception, localization, and control software required for aircraft to sense, avoid obstacles, and land accurately without GNSS on embedded hardware.

What You’ll Do

You will lead the development of our core drone autonomy stack:

• GPS-Denied Navigation & Localization: Maintain flight stability and precise positioning in environments where GNSS is unavailable.
• Autonomous Docking & Precision Landing: Build reliable systems for repeatable docking to stations in challenging conditions.
• Perception & Motion Planning: Implement real-time obstacle avoidance and path planning algorithms for smooth, collision-free flight.
• Edge Deployment: Optimize the autonomy stack for SiMa’s embedded hardware under strict power/weight limits.
• Systems & Test: Manage camera-IMU calibration, SIL/HIL rigs, and flight testing to close the sim-to-real gap.

Required Qualifications

• Flight Experience: 5+ years building autonomy software flown on real aircraft (multirotor, fixed-wing, or VTOL); integrated flight stacks (PX4/ArduPilot) via MAVLink.
• Autonomy Depth: Hands-on expertise in VIO/SLAM, multi-sensor fusion, state estimation, and closed-loop control.
• Software & Math: Fluent in modern C++, Python, and ROS 2; strong grasp of 3D geometry and rigid-body dynamics.
• Education: BS/MS in Robotics, Aerospace, CS, EE, or a related field.

Good To Have

• Certification to DO-178C/DO-254 or familiarity with AMC 20-193 (neural network assurance).
• Experience with edge accelerators (Jetson, etc.) and Factor-graph optimization (GTSAM/Ceres).
• FAA Part 107 certification and field flight-test experience.

Why it matters

GPS-denied autonomy and reliable docking are the key differentiators for deployable drones. The stack you build will set the benchmark for SiMa silicon and will ship in every drone program adopting our platform.

Personal Attributes

Can-do attitude. Strong team player. Curious, creative and good at solving problems. Execution and results-oriented. Self-driven, Thinks Big and is highly accountable. Good communication skills.

The annual salary for this position ranges from $120,800 - $193,300. The actual annual salary offered will depend on several factors, including - among others - job-related skills, experience, technical expertise, qualifications, work location, and business needs. The annual salary range for this position is subject to change and may be adjusted in the future. In addition to base salary, this role is also eligible for private company equity, and a comprehensive package of employee benefits. Please note that the salary ranges listed for U.S. roles reflect base salary only and do not include equity or other forms of compensation.
