Principal Antenna Engineer

Redwood City, CA
Engineering /
Full-time /
At Reach, we are delivering technologies to enable the long-range, wireless transfer of power. We believe wireless energy can be as liberating for power systems as WiFi was for data systems, and are busy creating the energy infrastructure that will one day replace the aging electrical grid. We have raised funding from top tier VC's, have real world customers deploying our technology, and are continuing to build out the exceptional team that is making our vision a reality.

You will develop antennas and antenna arrays for Reach state-of-the-art wireless power delivery system. Your technical know-how and innovation skills are key to designing cutting-edge products in a fast-paced environment. You will work with other engineers to integrate antenna and antenna arrays in our system. This position requires hands-on experience and strong analytical skills to design, implement, test, and troubleshoot complex use cases of a complex, first-of-its kind system. It also requires experience in integration with complex software algorithms.

Reach - Who We Are

Reach is a pioneer in a new frontier of technology. Born out of MIT, incubated in YC, and developed in an "office space" that was once the oven of a cookie factory, we are a group of curious, passionate, and creative problem solvers, and we approach our work with vigor and humility.

Much has changed since our cookie factory days, but our core philosophies have remained. Decisions are made quickly, meetings and politics are kept to a minimum, and everyone here does high-visibility work that has considerable influence on our product and company. We have weekly team lunches, quarterly offsite company events, and often spend time together outside of work bicycling, rock climbing, playing music, and hosting happy hours.

We highly value diversity at our company - in not only professional capabilities and experience, but also in personal interests, schools of thought, musical tastes, and walks of life. We prioritize inclusivity, and do not discriminate on the basis of race, religion, national origin, gender, sexual orientation, age, marital status, veteran status, or disability status.

In compliance with federal law, all persons hired will be required to verify identity and eligibility to work in the United States.
