## Job description

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.

The mechanical team is a small group of highly motivated people designing, testing, and flying advanced mechanical systems. We enjoy cradle-to-grave hardware ownership and hands-on build, test, and integration of our designs. As a Sr. Mechanical Engineer at Reliable Robotics, you will be an influential part of the Mechanical Engineering team helping to drive engineering methods and product quality. The hardware focus is on high reliability safety critical mechanisms and structures, with significant cross-functional development with the Systems, Avionics, GNC, Software, Manufacturing, and Flight Test teams. The position will be located at our facility in Mountain View, California, or our Seattle location reporting to the Mechanical Engineering Manager.

## Responsibilities

You will design, analyze, build, test, and fly a system of actuators, mechanisms, and structural modifications to enable remote piloted aircraft. Own your hardware from initial conception through flight test and certification...this is cradle-to-grave engineering with hands-on build, test, and integration. Lead cross-functional trades and drive performance and design decisions to closure. You will bring a sense of humility, and be ready to both learn and teach.

## Basic Success Criteria

- BS in mechanical or aerospace engineering, or equivalent experience
- 5+ years professional experience developing mechanical systems
- Mastery of at least one of the following areas: Design, Analysis, Manufacturing, Test, or Certification
- Demonstrated successful project ownership

## Preferred Criteria

- Demonstrated understanding of structural analysis and failure modes of mechanical systems
- Ability to assess and prioritize mechanical architectures for safety and reliability
- Previous experience with aircraft or other safety-critical mechanical systems
- Experience developing engineering infrastructure such as CAD systems, configuration management, PLM, ERP, and MRP systems
- Design for manufacturability and volume production
- Eagerness and ability to mentor junior engineers
- Proactive problem solver
- Excellent written and verbal communication skills

Must be willing to travel up to 25 % of the time.

The estimated salary range for this position is $180,000 to $260,000/annual salary + cash and stock option awards + benefits. At Reliable Robotics, we strive to provide competitive and rewarding compensation based on experience and expertise, as well as market conditions, location, and pay equity.

In addition to base compensation, Reliable Robotics offers stock options, employee medical, 401k contribution, great co-workers and a casual work environment.

This position requires access to information that is subject to U.S. export controls. An offer of employment will be contingent upon the applicant’s capacity to perform in compliance with U.S. export control laws.
