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.

As an RF Hardware Design Engineer, you will be a part of our Radar Engineering team. The Radar Engineering team is comprised of a small cross‑functional team of motivated and experienced engineers; we’re responsible for designing, building, and testing cutting‑edge phased array radar systems from concept to certified product. We enjoy a culture of sharing information and collaboration. Phased array radar systems have historically been reserved for specialized applications, but we’re making this technology affordable to enable Detect and Avoid for widespread commercial applications. This role will focus on new advanced operational modes. The passion for revolutionary technology to make aviation safer motivates us to come in every day.

Responsibilities

In your role as an RF Design Engineer, you will be responsible for designing digital and analog circuits for our next‑generation Radar system. You will be involved in all phases of development, from conception to production, tracing system‑level requirements through to circuit‑level design. You will drive the design and layout of a multi‑processor with an FPGA on chip using DDR 4 memory, as well as designing switching and linear power supplies. The high‑speed digital design is complemented by high‑frequency analog and RF design up to 12GHz. You will own the schematic, layout, artwork generation and bring‑up of hardware. You will be collaborating with the cross‑functional teams, including mechanical and system engineering. You will be responsible for the certification of your design to DO-160, DO-254 design assurance and FCC certification. You will support radar system integration and testing in the engineering lab and on the aircraft.

Basic Success Criteria

• Electrical Engineering fundamentals, typically gained through a Bachelor's Degree of Science or Engineering in Electrical, Aerospace, or a related discipline
• 5+ years of professional hands‑on experience with high‑speed digital circuits, linear and switching power regulator circuits, PLL's, VGA, mixers etc.
• Ability to use Circuit simulators, Altium schematic capture and layout, and SPICE simulation software
• Ability to troubleshoot, find root cause, and resolve issues
• Experienced in using oscilloscopes, logic analyzers, spectrum analyzers and Vector Network Analyzers

Preferred Criteria

• Advanced Degree of Science or Electrical Engineering
• RF circuit design experience up to 12GHz
• Experience developing system architectures and managing requirements for certification of Avionics
• Creative problem solver that can bring multiple disciplines together, with the ability to assess risk and make design and development decisions without all available data
• Experience integrating and troubleshooting various electronic sensors and components
• DO-160 and DO-254 hardware design assurance experience
• Must be willing to travel 10% of the time.

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.

All applicants are asked to provide documentation that legally establishes status as a U.S. person or non-U.S. person (and nationalities in the case of a non-U.S. person).
