Life360 delivers peace of mind and enhances everyday family life with seamless coordination for all the moments that matter, big and small.

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 and Canada) regardless of any specified location above.
We are building an AI native company where AI is an integral part of how we build and operate. AI tool usage during interviews varies by role. You may be asked to demonstrate proficiency with AI tools, discuss how you leverage AI, or complete interview exercises without AI assistance. Your Recruiter will provide clear guidance as you move through the interview process.
Undisclosed use of AI not previously discussed with or approved by your Recruiter may impact your candidacy.
The On App Ads Engineering team owns the ads layer inside the Life360 app, which reaches approximately 102.4 million monthly active users. We build and maintain the SDK, header-bidding and mediation integrations, ad quality, and consent behind every ad on iOS and Android, serving 300M+ ad requests a day. We also own the testing and monitoring that keep that stack reliable, so every impression is competitively priced, respects each member’s privacy choices, and renders safely.
We guide the direction of our future advertising experience by introducing new formats, placements, and capabilities that grow revenue while protecting the member experience. We work closely with the Ad Server & Exchange team, Ad Operations, Data, and Privacy, and we ship through controlled experiments, so every new ad surface proves its revenue lift without costing member trust. We build with AI agents because a small team owns a large surface of SDKs, partner integrations, and privacy regimes, and agents let us ship and test more of it without trading away quality.
Life360 is hiring a Senior Software Engineer II for Mobile, On App Ads, to join our AI Native engineering team. This is a senior engineer who doesn't just use AI tools, but thinks natively in them. You'll be central to how the Ads Engineering team builds, scales, and evolves monetization in the Life360 app, and to how we use AI for development going forward.
You'll own key parts of the ads stack on iOS: our in-house ads SDK, header-bidding and mediation integrations, consent and privacy flows, and the ad formats and placements members actually see. The bar is high on two fronts at once. Ads have to perform for the business, and they have to respect the member experience in an app that families rely on for safety.
This role is iOS-first. Most of your work will be in Swift on the iOS app and SDK. Our AI-Native way of working also rewards engineers who treat platform boundaries as fluid, so you should be willing to build on Android, ad-server config, or backend when a partner integration or experiment calls for it.
We’re expanding on-app ad formats and demand partners, and the iOS stack has to scale with it. You’ll be the engineer who makes that happen, across 300M+ daily ad requests and 10+ partners, without costing the member experience.
In your first year, success looks like this:
For candidates based in the US, the salary range for this position is $118,500 to $216,500 USD. For candidates based out of Canada, the salary range for this position is 171,500 to 201,000 CAD. Note: Please be aware that the job title for positions in Canada will be "Developer" in lieu of "Engineer."
We take into consideration an individual's background, job-related knowledge, skills, and experience in determining final salary. Base pay may also vary based on geographic location, with US work locations falling into one of three geographic tiers.
Total compensation is inclusive of equity compensation in the form of Restricted Stock Units (RSUs), as well as a comprehensive benefits package, including medical, dental, vision, financial, and other benefits.
We use AI coding tools as a professional standard on this team. Here's what that means in practice:
