Senior Quality Engineer (mobile)

<h2>About Lendable</h2><p style="min-height:1.5em">Lendable is on a mission to build the world's best technology to help people get credit and save money.<strong> </strong>We're building one of the world’s leading fintech companies and are off to a strong start:</p><p style="min-height:1.5em"></p><ul style="min-height:1.5em"><li><p style="min-height:1.5em">One of the UK’s most exciting unicorns with a team of over 800 people</p></li><li><p style="min-height:1.5em">Among the<strong> fastest-growing tech</strong> companies in the UK</p></li><li><p style="min-height:1.5em">Profitable since <strong>2017</strong></p></li><li><p style="min-height:1.5em">Backed by top investors including <strong>Balderton Capital </strong>and<strong> Goldman Sachs</strong></p></li><li><p style="min-height:1.5em"><strong>Loved by customers</strong> with the best reviews in the market (4.9 across 10,000s of reviews on <a target="_blank" rel="noopener noreferrer nofollow" href="https://uk.trustpilot.com/review/lendable.co.uk"><u>Trustpilot</u></a>)</p></li></ul><p style="min-height:1.5em"></p><p style="min-height:1.5em">So far, we’ve rebuilt the Big Three consumer finance products from scratch:<strong> loans, credit cards and car finance</strong>. We get money into our customers’ hands in minutes instead of days.</p><p style="min-height:1.5em"></p><p style="min-height:1.5em">We’re growing fast, and there’s a lot more to do: we’re going after the two biggest Western markets (UK and US) where trillions worth of financial products are held by big banks <strong>with dated systems and painful processes.</strong></p><p style="min-height:1.5em"></p><h2>Join us if you want to</h2><ol style="min-height:1.5em"><li><p style="min-height:1.5em"><strong>Take ownership: </strong>you are trusted to make decisions that drive a material impact on the direction and success of Lendable from day 1</p></li><li><p style="min-height:1.5em"><strong>Work in small teams of exceptional people:</strong> Lendies are relentlessly resourceful. We challenge the status quo to solve problems and find smarter solutions</p></li><li><p style="min-height:1.5em"><strong>Build the best technology in-house</strong>: we use new data sources, machine learning and AI to make machines do the heavy lifting</p></li></ol><p style="min-height:1.5em"></p><p style="min-height:1.5em"><strong>About the role</strong><br /><br />We're hiring two Senior Quality Engineers to join our Mobile team at Lendable and help us ship our apps with confidence as we keep scaling.</p><p style="min-height:1.5em">Our mobile app, Zable, is how most of our customers experience all of our products in one centralised space. It's written in React Native and TypeScript with a Kotlin backend, shipped to iOS and Android from a single codebase. We are now looking to level up the quality engineering so that we can raise release cadence without losing sleep over regressions.</p><p style="min-height:1.5em">This is an automation-first role. You'll spend most of your time writing code - test frameworks, CI tooling, helpers, rather than executing test scripts by hand. You'll work alongside software engineers, product, and design, setting direction.</p><p style="min-height:1.5em">You'll also be working at the frontier of AI-assisted quality, using LLMs and AI tooling to speed up test authoring, triage failures, and surface coverage gaps, while applying the engineering judgement to keep tests trustworthy.</p><p style="min-height:1.5em"></p><h2>What you'll be doing</h2><p style="min-height:1.5em">Own the mobile test strategy:</p><ul style="min-height:1.5em"><li><p style="min-height:1.5em">Define and evolve a pragmatic test pyramid for React Native - deciding where E2E is worth the weight and where logic belongs in faster layers (Jest, React Testing Library, component tests).</p></li><li><p style="min-height:1.5em">Make deliberate calls about coverage, reliability, and speed trade-offs across the app.</p></li><li><p style="min-height:1.5em">Set the bar for what "ready to ship" looks like on mobile, and hold the line on it.</p></li></ul><p style="min-height:1.5em">Build reliable E2E automation:</p><ul style="min-height:1.5em"><li><p style="min-height:1.5em">Create and maintain mobile E2E suites in Maestro, including the scaffolding around them - test data, device configuration, helpers, reporting.</p></li><li><p style="min-height:1.5em">Integrate suites into CI (GitHub Actions) so engineers get fast, trustworthy feedback on every PR and release candidates carry a signal people actually believe.</p></li><li><p style="min-height:1.5em">Drive flakiness down and time-to-diagnosis down. We treat a flaky test the same way we treat a broken test, and we expect root-cause work rather than retry-until-green.</p></li></ul><p style="min-height:1.5em">Bring AI into the SDLC:</p><ul style="min-height:1.5em"><li><p style="min-height:1.5em">Use AI tools day-to-day to accelerate test authoring, cluster failures, surface coverage insights, and propose fixes.</p></li><li><p style="min-height:1.5em">Decide where AI adds leverage and where a human eye is needed. A suite that looks comprehensive but isn't trustworthy is worse than a smaller one we rely on.</p></li><li><p style="min-height:1.5em">Help shape how the mobile team uses AI-assisted workflows more broadly - prompts, guardrails, review patterns.</p></li></ul><p style="min-height:1.5em">Prevent defects, not just catch them:</p><ul style="min-height:1.5em"><li><p style="min-height:1.5em">Partner with product and engineering on shift-left quality: join specs early, push back on ambiguous acceptance criteria, and surface risk before code is written.</p></li><li><p style="min-height:1.5em">Close the loop on production issues using our observability stack (Datadog, Sentry, Grafana) - tying test coverage back to real customer impact.</p></li><li><p style="min-height:1.5em">Run targeted exploratory testing on high-risk releases when it's the right call.</p><p style="min-height:1.5em"></p></li></ul><h2>What we're looking for</h2><p style="min-height:1.5em">Essential:</p><ul style="min-height:1.5em"><li><p style="min-height:1.5em"><strong>6+ years in quality engineering or test automation</strong>, with a track record of keeping automated suites stable rather than letting them rot into a graveyard of quarantined tests.</p></li><li><p style="min-height:1.5em"><strong>Experience introducing AI-assisted testing practices </strong>(test generation, failure clustering, coverage analytics) with sensible controls around review and trust.</p></li><li><p style="min-height:1.5em"><strong>Strong TypeScript and JavaScript </strong>- not just writing test scripts, but building helpers, tooling, and debugging into the app when needed.</p></li><li><p style="min-height:1.5em"><strong>Experience shaping CI/CD pipelines for test reliability</strong> (GitHub Actions or similar), including flakiness reduction, parallelisation, artefact management, and runtime control.</p></li><li><p style="min-height:1.5em"><strong>Comfortable with mobile E2E automation</strong>, or strong E2E experience on another platform plus a credible plan for getting productive on mobile quickly.</p></li><li><p style="min-height:1.5em"><strong>Able to operate independently </strong>and drive improvements end-to-end (frameworks, CI, test data, reporting).</p></li></ul><p style="min-height:1.5em">Desirable:</p><ul style="min-height:1.5em"><li><p style="min-height:1.5em">Hands-on with <strong>Maestro or Detox.</strong></p></li><li><p style="min-height:1.5em">Hands-on experience testing React Native apps.</p></li><li><p style="min-height:1.5em">Mobile performance and reliability work (crash reporting, startup time, memory and battery awareness).</p></li><li><p style="min-height:1.5em">API and contract testing experience, with a point of view on test data and environment strategy.</p><p style="min-height:1.5em"></p></li></ul><h2>Our tech stack</h2><p style="min-height:1.5em"><strong>Mobile: </strong>TypeScript, React Native, Expo, EAS, GraphQL, Relay, Jest, React Testing Library, Maestro.</p><p style="min-height:1.5em"><strong>Backend: </strong>Kotlin, PHP 8 (Symfony), AWS, Postgres, RabbitMQ, Docker, Kubernetes.</p><p style="min-height:1.5em"><strong>Tooling and observability: </strong>GitHub, GitHub Actions, Jira, Confluence, Datadog, Sentry, Grafana.</p><p style="min-height:1.5em"></p><h2>Interview process</h2><ol style="min-height:1.5em"><li><p style="min-height:1.5em">Quick call with a Recruiter</p></li><li><p style="min-height:1.5em">15 minute cognitive test</p></li><li><p style="min-height:1.5em">Hiring manager interview (30 minutes)</p></li><li><p style="min-height:1.5em">Technical interview (90 minutes)</p></li><li><p style="min-height:1.5em">Culture-add interview (60 minutes)</p></li></ol><p style="min-height:1.5em"></p><h2>Life at Lendable</h2><ul style="min-height:1.5em"><li><p style="min-height:1.5em"><strong>Winning team: </strong>the opportunity to scale up one of the world’s most successful fintech companies</p></li><li><p style="min-height:1.5em"><strong>Flexible working: </strong>flexible approach tailored to each role.
