Job Description

We’re hiring a QA Engineer to strengthen product reliability and automated test coverage across Diesta’s platform. You’ll work side by side with our Lead QA Engineer and report to our Head of Engineering.

This is not a manual-testing-only role. You will help us understand, protect and evolve the core user journeys, business rules and system variants that make up our product. You’ll use that knowledge to build trusted, maintainable automated coverage, while applying exploratory testing where human judgement adds the most value.

You will work across our Angular Portal and backend services, using Playwright, Cucumber and TypeScript to test UI, API and end-to-end workflows. You’ll be comfortable navigating codebases, understanding the impact of change, and contributing test code - and occasionally product code - where it improves testability and reliability.

We are moving from an AI-driven SDLC towards a more agentic one. We want someone excited to use AI thoughtfully to improve quality, automate repeatable work, and help build a quality function that scales with product growth rather than with headcount alone.

Key Responsibilities

Define and evolve test strategies for our Portal and backend applications.

Build and maintain automated test suites using Playwright, Cucumber and TypeScript, covering UI, API, integration and end-to-end scenarios.

Learn and maintain a clear understanding of the platform’s core workflows, business rules, variants and dependencies.

Identify high-value regression scenarios and ensure they remain protected as the product evolves.

Navigate Angular, TypeScript, NestJS and Python codebases to understand change impact, identify risk and write meaningful tests.

Contribute test code and, where appropriate, small product or tooling changes that improve testability, reliability or observability.

Perform focused exploratory testing on new features, complex workflows and edge cases; turn stable, high-value findings into automated coverage.

Work with developers and Product to define clear, testable requirements before work is completed.

Work with DevOps to keep test coverage integrated into the delivery process and reduce flaky or low-signal checks.

Turn production incidents and defects into stronger coverage and preventative quality improvements.

Use AI tools and agentic workflows to improve test design, test authoring, test maintenance, defect triage and documentation.

Identify repetitive QA activity that should be automated, improved or removed, and help make that happen.

Key Collaborators

With our Lead QA Engineer: Help shape and extend our approach to quality, test coverage and automation. Map the product’s critical flows, variants and regression risks, and turn them into durable protection.

With Developers: Drive quality early in the development process. Read and understand code changes, identify risk, support test-driven development, contribute test code and review coverage in pull requests.

With Product: Help define testable acceptance criteria, expose ambiguity before it becomes a defect, and make sure important workflows and edge cases are understood.

With DevOps: Coordinate on test execution in CI/CD, test environments, test data and flaky-test monitoring. Help ensure automated checks provide fast, reliable feedback before release. What We're Looking For

  • 3+ years’ experience in QA, Test Engineering, SDET, or a similar software quality role.

  • Strong experience in automated web testing, ideally with Playwright and TypeScript.

  • Experience with Cucumber or another BDD framework.

  • Confidence reading, navigating and contributing to application code; this is not a role limited to executing manual test scripts.

  • Experience testing modern web applications, REST APIs and backend workflows.

  • Ability to reason through complex business workflows, state changes, edge cases and failure modes.

  • A track record of building or improving automated regression coverage for important product journeys.

  • Familiarity with Git, pull requests and CI/CD-based development practices.

  • Good judgement about when to automate and when exploratory testing is the better tool.

  • Clear communication skills and the ability to explain quality risk, defects and trade-offs concisely.

  • Curiosity about AI-assisted and agentic ways of working, and a practical interest in automating repetitive parts of the QA role.


Bonus if you’ve worked with

  • Angular, NestJS, Python or TypeScript-based backend services.

  • API, contract, database or event-driven-system testing.

  • SQL and data-heavy workflow validation.

  • Insurance, insurtech, fintech or other complex regulated-domain workflows.

  • Performance, accessibility or security testing.

  • AI coding assistants, agentic workflows, custom prompts, skills or tooling that improve QA delivery.

Why Join Diesta?
  • Help protect high-trust software in a complex, meaningful domain.

  • Build real automated coverage, contribute to code, and influence how we design, test and release software.

  • Work closely with an experienced Lead QA Engineer, developers, Product, DevOps and engineering leadership - not in a silo.

  • Help us make practical progress towards an AI-driven and increasingly agentic SDLC.

  • Build quality systems that make the team faster, more confident and more scalable as Diesta grows.


Benefits
  • Hybrid work model with a central London office (Monument/London Bridge).

  • Private healthcare/medical/life insurance.

  • Regular team lunches and international offsites.

  • 22 days annual leave (excluding bank holidays).

Job Description

Starling is the UK’s first and leading digital bank on a mission to fix banking! Our vision is fast technology, fair service, and honest values. All at the tap of a phone, all the time.

Our technologists are at the very heart of Starling and enjoy working in a fast-paced environment that is all about building things, creating new stuff, and disruptive technology that keeps us on the cutting edge of fintech. We operate a flat structure to empower you to make decisions regardless of what your primary responsibilities may be, innovation and collaboration will be at the core of everything you do. Help is never far away in our open culture, you will find support in your team and from across the business, we are in this together!

The way to thrive and shine within Starling is to be a self-driven individual and be able to take full ownership of everything around you: From building things, designing, discovering, to sharing knowledge with your colleagues and making sure all processes are efficient and productive to deliver the best possible results for our customers. Our purpose is underpinned by five Starling values: Listen, Keep It Simple, Do The Right Thing, Own It, and Aim For Greatness.

Hybrid Working

We have a Hybrid approach to working here at Starling - our preference is that you're located within a commutable distance of one of our offices so that we're able to interact and collaborate in person. We don't like to mandate how much you visit the office and work from home, that's to be agreed upon between you and your manager.

Our Data Environment

Our Data teams are excited about the value of data within the business, powers our product decisions to improve things for our customers and enhance effective and agile decision making, regardless of what their primary tech stack may be.

People with a broad ability to apply themselves to a multitude of problems and challenges, who can work across teams do great things here at Starling, to continue changing banking for good.

Requirements

We have built our entire banking platform in house and mostly in Java. We are looking for people who want to work on building the tooling that is used by our engineers on a daily basis.

We are looking for people who are truly full stack, and are as comfortable polishing their javascript front end as they are debugging the innards of their java applications database interactions, or standing up infrastructure with terraform. We are looking for people who can:

  • Design REST apis.
  • Code backend services, ideally using Java, or another other server side compiled language.
  • Develop modern front ends, ideally using React and Redux.
  • Get their code into the cloud and support it there, ideally on AWS.
  • Believe in clean coding, simple solutions, automated testing and continuous deployment.
  • Like to take ownership of a feature from the original idea through to live.
  • Think (like us) that a small number of empowered developers is the right way to deliver software.
