Staff Backend Engineer – Location Platform

Life360’s mission is to keep people close to the ones they love. Our category-leading mobile app, Tile tracking devices, and Pet GPS tracker empower members to protect the people, pets, and things they care about most with a range of services, including location sharing, safe driver reports, and crash detection with emergency dispatch. Life360 serves approximately 91.6 million monthly active users (MAU), as of September 30, 2025, across more than 180 countries.

Life360 delivers peace of mind and enhances everyday family life with seamless coordination for all the moments that matter, big and small. By continuing to innovate and deliver for our customers, we have become a household name and the must-have mobile-based membership for families (and those friends who are basically family).

Life360 has more than 500 (and growing!) remote-first employees. For more information, please visit life360.com.

Life360 is a Remote-First company, which means a remote work environment will be the primary experience for all employees. All positions, unless otherwise specified, can be performed remotely (within the US) regardless of any specified location above. 

The Location Experiences team owns the location platform that powers Life360’s core value proposition: delivering fast, accurate, and emotionally resonant location experiences to over 90 million members worldwide. We are responsible for the data collection strategy, location intelligence, and real-time processing infrastructure that enables families to answer “Where is my family?”

Our backend systems process billions of low latency location events daily, handle high-frequency device telemetry, and provide the location platform and APIs that other teams build on. We work at the intersection of distributed systems, geospatial computing, and real-time data processing—building the foundation that turns location data into peace of mind, safety, and connection for millions of families.

This is a small, high-impact team where individual contributions directly shape system architecture, platform reliability, and the core member experience.

We are seeking a Staff Backend Engineer to architect, build, and evolve our location platform infrastructure. This is a critical, high-impact role for an exceptional distributed systems engineer who will take technical ownership of complex subsystems, drive architectural direction, and solve hard problems at the intersection of geospatial computing, high-throughput data processing, and real-time systems.

You will work on systems processing billions of location events per day, design scalable geospatial services, build resilient distributed architectures using Kafka and NATS, and create libraries and frameworks that other engineering teams depend on. This role requires deep expertise in distributed systems, location and geospatial algorithms, and a track record of leading complex technical initiatives across multiple teams.

The US-based salary range for this position is 200k to 280k. The Canada-based salary range for this position is 220k to 260k CAD. 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.

• Design, architect, and build high-throughput, low-latency backend systems for real-time location processing, geofencing, and location intelligence at scale (billions of events/day)
