The Developer Experience (Dev Ex) department plays a pivotal role in shaping how mobile engineering teams build, test, and ship software. Dev Ex owns the underlying tools, frameworks, and mobile infrastructure that power Life
360’s flagship iOS and Android applications and support the mission‑critical experiences used by more than 88 million members.

We build the systems that make engineering at Life
360 fast, reliable, and enjoyable—from modernizing our mobile architecture to evolving our build and CI pipelines, to creating internal frameworks, code‑generation tools, automation utilities, and high‑leverage platform abstractions. Our work directly shapes the foundation on which all mobile features are built, enabling engineers to deliver high‑quality, high‑impact experiences for families at scale.

We are looking for a Staff iOS Engineer to join our Developer Experience (Dev Ex) organization. You will shape the vision and execution of the tools, frameworks, architecture, and mobile infrastructure that empower mobile product teams to ship high‑quality features faster and more reliably.
