Senior AI Quality Engineer

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 newest unicorns with a team of just over 700 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 across a broad remit.

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, who are relentlessly resourceful to solve problems and find smarter solutions than the status quoBuild the best technology in-house, using new data sources, machine learning and AI to make machines do the heavy liftingWe're hiring two Senior Quality Engineers to set up a Quality Engineering department at Lendable alongside a new Head of Quality.At 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.This is an automation-first role. You'll spend most of your time writing code - AI Agents, test frameworks, CI tooling, helpers. You won't be executing tests by hand.

You'll work cross-functionally with software engineers, product and design. Quality is a team-level responsibility and your job is to work with teams to enable them to improve their quality processes by hands-on collaboration.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 doingEnable 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 regressBring 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 For

Essential5+ 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 haveHave worked with an incident management process to root cause issues with engineers and devise meaningful quality improvements as a resultExperience in PHP, Kotlin or TypescriptExperience in financial services (retail or institutional) or other regulated environmentsOur tech stackFrontend: TypeScript, React, React NativeBackend: PHP (Symfony), Kotlin, AWS, Postgres, RabbitMQ, Docker, KubernetesTesting: PHPUnit, Behat, JUnit, Kotest, Jest, Maestro, K6Tooling and observability: GitHub, GitHub Actions, Jira, Confluence, Datadog, Sentry, GrafanaWhy join?See your work matter: Our products are used by millions of customers - the quality bar you help set has a direct line to customer trust and company revenueHigh impact: You'll decide where and how to engage across teams to move quality forward, working hands-on rather than through process layersWork at the frontier of AI: AI tooling for quality is moving fast. 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 decisionsInterview 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.
