About the role
We're building safety-enhancing technology for aviation that will save lives. Automated aviation systems will enable a future where air transportation is safer, more convenient and fundamentally transformative to the way goods — and eventually people — move around the planet. We are a team of mission-driven engineers with experience across aerospace, robotics and self-driving cars working to make this future a reality.
As a Senior Flight Navigation Engineer at Reliable Robotics, you will be part of the Guidance, Navigation and Control Team. You will contribute to the navigation system design, implementation, and testing, and your work will enable the integration of uncrewed aircraft into the National Airspace System.
Responsibilities
- Define navigation system requirements in collaboration with internal and external stakeholders
- Analyze, source, and select sensor solutions for use in the navigation system
- Develop sensor models in simulation for evaluation of the navigation system
- Implement state estimation algorithms in flight software
- Establish test methods to ensure compliance with requirements, best practices, and regulatory standards
- Evaluate the navigation system performance via simulation, hardware-in-loop, and flight test cases
Basic Success Criteria
- MS in aerospace engineering, electrical engineering, computer science, or similar advanced degree
- Technical expertise in one of the following areas: Kalman filtering; GNSS navigation; inertial navigation; or alternative navigation technologies
- 8+ years of professional experience developing and testing navigation algorithms
- Professional experience with developing C/C++ flight software and Python data reduction & analysis
- Excellent written and verbal communication skills
Preferred Criteria
- PhD in aerospace engineering, electrical engineering, computer science, or similar advanced degree
- Technical expertise in one of the following areas: probability theory; fault detection and exclusion (FDE); sensor error/noise modeling; or GPS-denied navigation
- Experience developing software for safety critical applications
- Experience with navigation system certification
We are building high-integrity, safety-critical systems for automated flight, and your role is critical to what we do at Reliable Robotics. With the support of the whole team, you will contribute to a novel navigation system that drives our mission forward.
Employees working from our headquarters in Mountain View, CA may expect very little travel. Employees working from Seattle, WA or remotely can expect 20% travel.
