Senior II Hardware Engineer (EE)

Life360 is a company dedicated to keeping families connected through innovative technology solutions. They are seeking a Senior Hardware Engineer (EE) to contribute to the development of next-generation GPS tracking devices, focusing on circuit design, PCB design, and prototyping for multi-radio consumer devices.

Responsibilities:

• 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
• Validate schematics, review component selections, and chase down detailed specifications and vendor technical questions
• Perform DFMEA, PFMEA, stress analysis, and tolerance analysis to ensure design robustness
• Support board bring-up, debug, and iterative refinement from early prototypes through production-ready designs
• Prototype and Validate
• Build mockups and proofs-of-concept to support R&D exploration, technical feasibility assessments, and industrial design convergence
• Drive parallel prototyping efforts to accelerate learning and de-risk design decisions
• Support EVT, DVT, and PVT phases with clear design intent and fast iteration
• Build Tools and Fixtures for the Team
• Design and build programming jigs, test fixtures, dev boards, and interface helper boards used across the hardware and firmware teams
• Execute quick-turn board designs for tooling — practical, functional, and delivered fast
• Collaborate Across Disciplines
• Work closely with firmware engineers on hardware-firmware interfaces, test points, and debug access
• Partner with mechanical engineering and industrial design on form factor constraints, integration tradeoffs, and physical prototyping
• Interface with operations and manufacturing partners on DFM, DFA, and production readiness
• Engage directly with component suppliers and contract manufacturers to resolve technical questions and drive sourcing decisions
• Communicate and Document
• Proactively share findings, status, and technical insights with the team through clear written documentation
• Create thorough design documentation that others can build on and review
• Produce high-quality presentation materials when needed to communicate design decisions and tradeoffs to both technical and non-technical audiences

Requirements:

• 7+ years of experience in electrical engineering, with hands-on design for consumer electronics products shipped at scale
• Demonstrated experience with high-density, multi-radio electrical design — integrating combinations of BLE, WiFi, cellular, and/or GNSS in constrained form factors
• Strong command of Altium Designer for schematic capture and PCB layout
• Strong fundamentals in EE and physics — not just application-level tool proficiency, but genuine understanding of why circuits behave the way they do
• Experience designing for small size and high integration density where every tradeoff matters
• Experience with schematic validation, DFMEA/PFMEA, tolerance analysis, stress analysis, bench testing, laboratory testing, and alpha/beta test deployments
• Interest in leveraging AI-assisted engineering tools to accelerate design, analysis, and documentation workflows, using tools like Claude Code
• Fluency in using EE laboratory equipment including oscilloscopes, DMMs, data loggers, and soldering tools
• Strong written and verbal communication skills, with a habit of documenting work and sharing knowledge proactively
• Bachelor's degree in Electrical Engineering or a related technical field
• Experience across several of the following: Power system design (regulators, battery management, power budgeting)
• Design of battery-powered products including battery modeling and test strategies
• Signal processing and signal integrity
• Practical analog and mixed-signal circuit design
• MCU selection, integration, and peripheral interfacing
• Sensor integration (IMU, environmental, optical)
• Test fixture and programming jig design
• Experience working with CMs, ODMs, or overseas manufacturing partners
• Familiarity with RF coexistence and antenna placement considerations in multi-radio designs
