About The Position

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.

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.

Nice To Haves

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

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.
