Your story

• You hold a Bachelor’s or Master’s degree in Computer Science, Software Engineering, or a related technical field.
• With over 10 years under your belt, you've mastered the art of building and optimising high-performance and availability tech systems.
• You bring proven experience as a Principal Engineer, including building and scaling high-traffic services from the ground up by driving significant technical initiatives, and demonstrating strong business acumen.
• You possess strong problem-solving skills to tackle complex technical and product challenges, are a genuine team player, and communicate exceptionally well in English.

• Experience working with external partners and technology vendors is a plus.

Attributes of a successful candidate:

• Pragmatic Problem Solver: You excel at tackling complex challenges with practical, efficient solutions, always prioritising simplicity and avoiding unnecessary system complexity.
• Collaborative Influencer: A true leader rather than a manager, you’re adept at guiding team decisions and fostering consensus through professional and constructive influence.
