Note: The job is a remote job and is open to candidates in USA. Lendable is a fintech company building technology that helps people access credit and save money. The Senior Mobile Quality Engineer will lead mobile quality engineering for the Zable app by designing test strategies, building reliable automation, integrating tests into CI, and using AI-assisted quality workflows. The role also partners with product and engineering to prevent defects and connect test coverage to production impact.
Responsibilities
- 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
- 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
- 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
- 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
Skills
- Hands-on experience with Maestro or Detox
- 6+ 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 introducing AI-assisted testing practices (test generation, failure clustering, coverage analytics) with sensible controls around review and trust
- Strong TypeScript and JavaScript - not just writing test scripts, but building helpers, tooling, and debugging into the app when needed
- 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
- Able to operate independently and drive improvements end-to-end (frameworks, CI, test data, reporting)
- 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
Benefits
- Flexible working: flexible approach tailored to each role. Hybrid roles require three days in-office weekly; fully remote roles include regular opportunities for in-person connection through socials and off-sites
- Opportunities and events to come together, socialise, and get to know each other beyond the office walls
- Support for your physical and mental wellbeing, including private health cover
- Retirement savings plans
- Employee referral programme: earn a competitive bonus when you refer successful new team members
- Fully stocked kitchen, plus complimentary lunches prepared by in-house chefs on in-office days at select locations
- Cycle-to-work and electric vehicle salary sacrifice schemes available in select locations
