About The Team The Devices team at Life360 is responsible for building the connected hardware experiences that connect our families to people, pets, and things. We combine electrical, mechanical, firmware, and product design expertise to create delightful, reliable, and scalable products that bring peace of mind to millions of families. This role sits within the Hardware Engineering team and reports to the Director of Hardware Engineering. You will work closely day-to-day with electrical, RF, and mechanical engineers, supported technically by our Principal Hardware Engineer, on some of the most constrained and challenging consumer electronics problems in the industry — packing multiple radios, sensors, and power systems into devices small enough to clip onto a keychain or a pet collar. About the Job We are looking for a Senior Hardware Engineer (EE) to join our team and contribute hands-on to the next generation of Life360's device portfolio. This is a high-output individual contributor role focused on circuit design, schematic development, PCB design, prototyping, and validation for ultra-compact, multi-radio consumer devices. You will work across a complex design integrating BLE, WiFi, cellular, and GNSS radios — and potentially more — into very small form factors where every millimeter, microamp, and decibel matters. You will validate schematics, run down spec questions with vendors, build mockups and prototypes, execute DFMEA and PFMEA analyses, perform stress and tolerance analyses, and drive and execute a diversity of product tests. You will also design and build the tools that keep the broader team moving: dev boards, programming/test, and interface devices, and work closely with contract manufacturers to build prototypes and manufacturing infrastructure to enable mass production. This role is best suited for an engineer who is passionate about the craft of electrical design, thrives on solving hard integration problems under real constraints, and brings a strong bias toward action paired with thorough, self-reviewed work and leveraging of experts. The US-based salary range for this position is $109,500 to $199,500. We take into consideration an individual's background and experience in determining final salary - therefore, base pay offered may vary considerably depending on geographic location, job-related knowledge, skills, and experience. The compensation package includes a wide range of medical, dental, vision, financial, and other benefits, as well as equity. What You’ll Do Design and Build Complex, Multi-Radio PCBs Contribute to high-density electrical design for next-generation GPS tracking devices with BLE, WiFi, cellular, and GNSS radios on a single board.
