Job description

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 most exciting unicorns with a team of over 800 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

1. Take ownership: you are trusted to make decisions that drive a material impact on the direction and success of Lendable from day 1

2. Work in small teams of exceptional people: Lendies are relentlessly resourceful. We challenge the status quo to solve problems and find smarter solutions

3. Build the best technology in-house: we use new data sources, machine learning and AI to make machines do the heavy lifting

About the role

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.

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.

Enable teams to keep the quality bar high

• 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

Bring AI testing into the SDLC

• Speed up our SDLC by building agents that exploratory test changes and catch issues before they get to production

• Use AI tools day
