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.

-
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
