[Hiring] Senior II Hardware Engineer @Life360

Role Description

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.

• 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.

Qualifications

• 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.

Requirements

• 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

Benefits

• Competitive pay and benefits
• Medical, dental, vision, life and disability insurance plans (100% paid for employees)
• 401(k) plan with company matching program
• Mental Wellness Program & Employee Assistance Program (EAP) for mental well-being
• Flexible PTO, 13 company-wide days off throughout the year
• Winter and Summer Weeklong Synchronized Company Shutdowns
• Learning & Development programs
• Equipment, tools, and reimbursement support for a productive remote environment
• Free Life360 Platinum Membership for your preferred circle
• Free Tile Products
