**Workplace:** hybrid

**Department:** Engineering

## Description

**About LoopMe**

LoopMe is an AI company solving one of advertising's hardest problems: making brand advertising actually measurable — and making it perform. Our platform runs patented machine learning models across billions of consumer signals in real time, optimising campaigns toward outcomes like purchase intent, brand lift, and foot traffic rather than proxy metrics like clicks. The result is 2–5x better performance than industry benchmarks, at scale.

We operate a high-load programmatic infrastructure — processing millions of ad requests per second with sub-200ms response times globally. This isn't a layer on top of someone else's stack; it's built from the ground up, in-house, by the team you'd be joining. Founded in 2012 and headquartered in London, we now have 400+ people across 19 cities and have sustained 40% revenue CAGR since 2018. The engineering problems here are real, the ownership is genuine, and the scale is significant.

**The opportunity**

You'll own manual and exploratory testing across LoopMe's Android and iOS SDKs, playing a key role in quality decisions from feature definition through to release. Working closely with developers, automation engineers, and product managers, you'll define test strategies for new features and help shape how quality is approached as our SDK portfolio grows. This role sits within the Mobile SDK Quality team.

**What you'll do**

-   Design, write, and execute manual test plans and test cases for Android and iOS SDK releases and new feature work
-   Own exploratory, regression, and smoke testing across nightly builds and release candidates
-   Validate Adapter Certification builds across multiple OS versions and device configurations
-   Log, triage, and track defects in JIRA with clear reproduction steps and supporting evidence
-   Manage and maintain test cases in TestRail, keeping coverage current across all SDK projects
-   Partner with the automation team to identify high-value candidates for automated test coverage
-   Participate in sprint ceremonies and contribute to quality sign-off decisions
-   Advocate for quality best practices and drive process improvements as the team scales
