The firm is known for giving its technical teams significant autonomy, backed by world-class infrastructure, cutting-edge research capabilities, and a collaborative culture. Engineers here work on complex challenges involving low-latency architectures, hardware acceleration, machine learning, and large-scale distributed systems.

About the Role

You’ll play a key role in shaping and advancing the testing strategy across critical server-side components. This position is ideal for someone who enjoys working close to the code, building scalable automation solutions, and partnering with developers to embed quality throughout the development lifecycle.

Shape testing strategy within CI/CD workflows

Strengthen automated test coverage in existing pipelines and introduce improvements to increase reliability, performance, and visibility.

Support performance and non-functional testing

Contribute to automation efforts that validate system behaviour beyond core functionality.
