Staff Quality Engineer

Who you are

• Hands-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 tests
• Experience 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 them
• Hands-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 it
• API and contract testing experience, with a point of view on test data and environment strategy
• Have set up and used Service Level Objectives to define a contract of system reliability with stakeholders, and driven measurable improvements against them
• Native 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 tool
• Coaching other disciplines in quality. You evangelise quality practices and get others on board to solve quality problems together
• Experience shaping CI/CD pipelines for test reliability (GitHub Actions or similar), including flakiness reduction, parallelisation, artefact management, and runtime control
• Proactive, low-ego, and clear communicator, able to chase things down when blocked
• Able 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 each
• Hands-on experience testing React Native apps
• Mobile performance and reliability work (crash reporting, startup time, memory and battery awareness)

What the job involves

• 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
• 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
• 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
• Rotating around different product teams for short periods to level up quality
• Define 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 products
• Devise and set up performance benchmarks to ensure critical parts of our systems don't regress
• Speed up our SDLC by building agents that exploratory test changes and catch issues before they get to production
• 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 test suite that looks comprehensive but isn't trustworthy is worse than a smaller one we rely on
• Discover gaps in testing and help teams build comprehensive suites
• Get test environments and data fixtures to a level where they are easy to use and reliable
• 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
• 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
• Ensure teams have Service Level Objectives set up and are achieving them
• Run targeted exploratory testing on high-risk releases when it's the right call
• 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
