Senior Quality Engineer

About Lendable

Lendable 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 people

Among the fastest-growing tech companies in the UK

Profitable since 2017

Backed by top investors including Balderton Capital and Goldman Sachs

Loved 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 to

• Take 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 1
• Work in small teams of exceptional people, who are relentlessly resourceful to solve problems and find smarter solutions than the status quo
• Build the best technology in-house, using new data sources, machine learning and AI to make machines do the heavy lifting

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.

Our mobile app, Zable, is how most of our customers experience Lendable, loans, credit cards, car finance, mobile plans, subscriptions, and new products in development all in one place. It's written in React Native and TypeScript with a Kotlin backend, shipped to iOS and Android from a single codebase, and it's already in good shape. We are now looking to level up the quality engineering so 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 doing

Own 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.

Build reliable E2E automation

Create and maintain mobile E2E suites in Maestro, including the scaffolding around them - test data, device configuration, helpers, reporting.

Integrate suites into CI (GitHub Actions) so engineers get fast, trustworthy feedback on every PR and release candidates carry a signal people actually believe.

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.

Bring AI into the SDLC

Use AI tools day-to-day to accelerate test authoring, cluster failures, surface coverage insights, and propose fixes.

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.

Help shape how the mobile team uses AI-assisted workflows more broadly - prompts, guardrails, review patterns.

Prevent defects, not just catch them

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.

Close the loop on production issues using our observability stack (Datadog, Sentry, Grafana) - tying test coverage back to real customer impact.

Run targeted exploratory testing on high-risk releases when it's the right call.

What we're looking for

Essential

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 tests.

Strong TypeScript and JavaScript - not just writing test scripts, but building helpers, tooling, and debugging into the app when needed.

Appium, device farms, or emulator/simulator orchestration at scale.

Hands-on with Maestro or Detox.

Experience shaping CI/CD pipelines for test reliability (GitHub Actions or similar), including flakiness reduction, parallelisation, artefact management, and runtime control.

Comfortable with mobile E2E automation, or strong E2E experience on another platform plus a credible plan for getting productive on mobile quickly. We use Maestro on React Native with TypeScript and Expo - familiarity helps, but we'll back someone strong to ramp.

Able to operate independently and drive improvements end-to-end (frameworks, CI, test data, reporting).

Desirable

Hands-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.

Native mobile fundamentals (Swift or Kotlin) for when a React Native abstraction leaks.

Prior work introducing AI-assisted testing practices (test generation, failure clustering, coverage analytics) with sensible controls around review and trust.

Our tech stack

Mobile: TypeScript, React Native, Expo, EAS, GraphQL, Relay, Jest, React Testing Library, Maestro.

Backend: Kotlin, PHP 8 (Symfony), AWS, Postgres, RabbitMQ, Docker, Kubernetes.

Tooling and observability: GitHub, GitHub Actions, Jira, Confluence, Datadog, Sentry, Grafana.
