About LendableLendable is on a mission to build the world's best technology to help people get credit and save money. We're building one of the world’s leading fintech companies and are off to a strong start:One of the UK’s most exciting unicorns with a team of over 800 peopleAmong the fastest-growing tech companies in the UKProfitable since 2017Backed by top investors including Balderton Capital and Goldman SachsLoved by customers with the best reviews in the market (4.9 across 10,000s of reviews on Trustpilot)So far, we’ve rebuilt the Big Three consumer finance products from scratch: loans, credit cards and car finance. We get money into our customers’ hands in minutes instead of days.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 with dated systems and painful processes.Join us if you want toTake ownership: you are trusted to make decisions that drive a material impact on the direction and success of Lendable from day 1Work in small teams of exceptional people: Lendies are relentlessly resourceful. We challenge the status quo to solve problems and find smarter solutionsBuild the best technology in-house: we use new data sources, machine learning and AI to make machines do the heavy liftingAbout the roleAt Lendable we already have a number of profitable, award winning credit products. They have a good automated quality story. However, as our customer base has grown into the millions we need to keep evolving to keep the quality bar high. Advances in AI engineering also have enabled us to ship faster, but we need to ensure we are not regressing on our quality metrics.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.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.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. What you'll be doingOwn the mobile test strategy: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).Make deliberate calls about coverage, reliability, and speed trade-offs across the app.Set the bar for what "ready to ship" looks like on mobile, and hold the line on it.Enable teams to keep the quality bar highRotating around different product teams for short periods to level up qualityDefine and evolve the pragmatic test pyramid for our products - deciding where E2E is worth the weight and where testing belongs in faster layers (unit and component tests)Make deliberate calls about coverage, reliability, and speed trade-offs across our productsDevise and set up performance benchmarks to ensure critical parts of our systems don't regress Bring AI testing into the SDLCSpeed up our SDLC by building agents that exploratory test changes and catch issues before they get to productionUse AI tools day-to-day to accelerate test authoring, cluster failures, surface coverage insights, and propose fixesDecide where AI adds leverage and where a human eye is needed. A test suite that looks comprehensive but isn't trustworthy is worse than a smaller one we rely onBuild reliable E2E automationDiscover gaps in testing and help teams build comprehensive suitesGet test environments and data fixtures to a level where they are easy to use and reliableDrive 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-greenPrevent defects, not just catch themPartner with product and engineering on shift-left quality: join specs early, push back on ambiguous acceptance criteria, and surface risk before code is writtenClose the loop on production issues using our observability stack (Datadog, Sentry, Grafana) - tying test coverage back to real customer impactEnsure teams have Service Level Objectives set up and are achieving themRun targeted exploratory testing on high-risk releases when it's the right call What we're looking forEssentialHands-on experience with Maestro or Detox.5+ years in quality engineering or test automation, with a track record of keeping automated suites stable rather than letting them rot into a graveyard of quarantined testsExperience working in a scaled engineering environment with multiple teams pulling in different directions and priorities, and know how to navigate that to drive quality improvements across themHands-on coding experience of writing test code, frameworks, CI pipelines and other helper scripts. You know what a good test codebase looks like and you constantly improve itAPI and contract testing experience, with a point of view on test data and environment strategyHave set up and used Service Level Objectives to define a contract of system reliability with stakeholders, and driven measurable improvements against themNative AI-assisted working style. You can describe projects where AI meaningfully changed how you worked - test authoring, failure triage, coverage analysis - and where you decided it wasn't the right toolCoaching other disciplines in quality. You evangelise quality practices and get others on board to solve quality problems togetherExperience shaping CI/CD pipelines for test reliability (GitHub Actions or similar), including flakiness reduction, parallelisation, artefact management, and runtime controlProactive, low-ego, and clear communicator, able to chase things down when blockedAble to operate independently and drive improvements end-to-end (frameworks, CI, test data, reporting)Can point to 3-4 projects where you moved the needle on quality - for example improving SLO coverage or reducing incident rate - and can speak to the measurable impact of eachNice to haveHands-on experience testing React Native apps.Mobile performance and reliability work (crash reporting, startup time, memory and battery awareness).API and contract testing experience, with a point of view on test data and environment strategy.

You'll be one of the people deciding how we apply it - what's useful, what isn't, and where to keep humans in the loopAn organisation that ships: No layers, no theatre, fast decisions Interview processQuick call with a Recruiter15 minute cognitive testHiring manager interview (30 minutes)Technical interview (60 minutes)Culture interview (60 minutes)Life at LendableWinning team: the opportunity to scale up one of the world’s most successful fintech companiesFlexible working: flexible approach tailored to each role.
