## Description

**About the role**

We're looking for a **Senior QA Automation Engineer** to join an established trading platform development programme for a large enterprise client. The platform has been live in production for over 7 years, with most of the core team having worked on it for close to 5 years on average — a reflection of the stability, quality, and long-term nature of this engagement.

The system is production-critical and actively evolving, with a strong focus on performance, reliability, and maintainability. While Applied Blockchain is well known for distributed ledger and cryptography work, this role is focused on a non-blockchain trading system built using modern TypeScript-based technologies.

You'll be responsible for building and maintaining automated test pipelines, ensuring the quality of the platform as it continues to grow. You'll be joining a **highly experienced team** of senior engineers and QA engineers, where autonomy, technical ownership, and a commitment to quality are expected.

**What you’ll be doing**

-   Building and maintaining automated test pipelines utilising Playwright tests
-   Analyse, understand, and review the products’ functional and non-functional requirements and identify gaps and inconsistencies
-   Develop automated tests for software validation, ensuring high quality of the system
-   Understand LLMs/AI and spot where it can be used to improve personal/team efficiency and quality of the trading platform. However, your work remains your responsibility and you will be expected to understand and explain whether using LLMs or not
-   Collaborate with engineers from the early stages of delivery to ensure quality is considered throughout
-   Report and manage/triage existing defects, ensuring proper follow-up and actions are being taken by the team
-   Promote and adopt QA best practices, contributing to their continuous improvement
-   Contribute to the definition of test automation guidelines and standards in order to improve the software testing process

## Requirements

-   3+ years of experience writing automated tests for web and/or non-web applications
-   Strong knowledge of QA methodologies, tools and processes
-   Fluency in JavaScript/TypeScript and Git/GitHub
-   Experience with Jest, Playwright and BDD tools (e.g. Cucumber)

**Nice to have**

-   We have a preference for a hybrid working arrangement, however flexibility can be discussed depending on the candidate and location
-   Experience with high-volume, high-availability enterprise systems
-   Experience building or testing REST and/or WebSocket APIs
-   Exposure to trading applications in production
-   Performance testing experience with K6, Artillery or similar

## Benefits

-   5 days/per year for training
-   £1,000 annual allowance for training (up to 50% of this value can be used for you to buy workstation equipment to work from home)
-   In-person fun team events/team buildings every 3 months
-   Company equipment and onboarding kit
-   Annual bonus (dependent on company and personal performance)
-   Stock option plan
-   Birthday off
-   Generous employee referral programme
