Senior QA Engineer

Job Title: Senior Test Engineer
Location: Remote (UK)
Salary: £50,000 - £70,000

**All applicants must be SC Clearable**

Why Apply?
This is a rare opportunity for a Senior Test Engineer to build a testing function from the ground up. Our client is a fast-growing intelligence business, helping large organisations understand exactly who they're doing business with. Backed by recent Series A funding, they're scaling quickly, with major projects already signed off. With no automated testing currently in place, this is a genuine chance to shape the strategy, choose the frameworks, and define the quality culture from day one.

Responsibilities

• Own the overall testing strategy across multiple products
• Build a comprehensive end-to-end test suite in Playwright, covering critical user journeys and regression scenarios
• Keep CI pipelines fast and trusted
• Introduce contract testing using Pact or similar between APIs, microservices and event-driven components
• Build realistic integration environments using Docker, LocalStack and seeded MongoDB datasets
• Test complex asynchronous workflows, including batch processing, retries, dead-letter queues, idempotency and long-running operations
• Design reusable test data and automation frameworks
• Perform exploratory testing where needed
• Work closely with engineers to lift coverage across the development lifecycle

Requirements

• Must be SC clearable
• 4+ years' experience in test automation, QA engineering or an SDET role
• Strong software engineering skills in TypeScript or JavaScript
• Deep experience with Playwright (or Cypress with a genuine willingness to move across)
• Experience testing distributed or event-driven systems
• Experience designing integration testing strategies across multiple services
• Experience building or introducing contract testing
• Strong understanding of CI/CD, ideally GitHub Actions
• Excellent communication skills
• Advantageous: Docker, MongoDB, Vitest, Jest, OAuth2/OIDC, or a background in compliance, KYC/AML or fintech

What's in it for me?
A small, high-trust engineering team with genuine ownership and very little bureaucracy, at a business scaling fast off the back of new funding and major signed client work. Real influence over testing direction and tooling from the outset, becoming the technical lead for quality as the team grows around you. Fully remote across the UK, with the wider team meeting up in person once a quarter.

We are an equal opportunities employer and welcome applications from all suitably qualified persons regardless of their race, sex, disability, religion/belief, sexual orientation or age.
