Senior Software Engineer II, Mobile (Android)

## The Role

We're hiring a **Senior Software Engineer II, Mobile (Android)** on the Revenue Experimentation team: the engine behind how Life360 grows and monetizes responsibly across ads, subscriptions, and one-time purchases. You'll take a hypothesis, sometimes a fully-specced brief, sometimes a rough idea from a Slack thread or a data-science finding, and turn it into a running, safely-instrumented experiment in front of tens of millions of members. This role is Android-first, but we want builders who treat platform boundaries as fluid.

## What You'll Do

- Design and build high-quality Android growth and monetization features: subscription paywalls and pricing tests, ad placement and mediation experiments, one-time purchase (IAP) flows, and upsell surfaces, running many concurrent tests across the app
- Partner with product, design, data science, and analytics to translate hypotheses into shippable experiments, and push back when a plan doesn't hold up
- Work with AI (Claude Code or equivalent) as a first-class collaborator: orchestrate agents to draft specs, generate code and tests, verify results, and help review
- Instrument experiments accurately, exposure logging and analytics, so the results downstream teams rely on are trustworthy
- Ship polished, performant Android experiences with real attention to startup time, memory, battery, ANR, and crash-free rates
- Own staged rollouts end to end: ramp exposure, watch guardrails, and make the call on ship, hold, or roll back

## What We're Looking For

- Several years building and shipping production Android apps at consumer scale
- Strong Kotlin, and comfort reaching across iOS, web, or backend when an experiment calls for it
- Hands-on experience with A/B testing and experimentation: exposure logging, guardrail metrics, staged rollouts
- A default toward shipping and iterating rather than waiting for a perfect spec
- Genuine fluency with AI tooling as part of how you build, not a novelty

## Strong Advantages

Nice-to-haves, not strict requirements.

- Experience with subscriptions, paywalls, ads mediation, or in-app purchase flows
- Background in high-velocity experimentation on a large install base
- A track record of introducing a workflow that other teams adopted

## Why This Role Is Special

Your work shapes the revenue behind nearly 100 million members, and you'll help define what AI-native mobile engineering looks like at scale. Remote-first within the US and Canada, with real ownership of the surfaces you ship.

## Location

Remote (United States or Canada).

## Next Steps

Tell us about a mobile experiment you shipped end to end and what you learned when the numbers came back.
