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
