Model and query large security datasets using ClickHouse, ensuring strict tenant isolation.

Take end-to-end ownership of assigned projects, from understanding customer problems through to delivering solutions.

Engage directly with customers to understand their requirements and ensure their problems are resolved.

Independently manage priorities and deliver high-impact work while maintaining continuous communication and collaboration with the team.

Ability to work autonomously, set priorities and make decisions without constant supervision while maintaining effective communication and collaboration.

A growth mindset, with openness to constructive criticism, willingness to discard or rework code and projects when necessary, and commitment to improving the wider team.

A trustworthy and accountable approach, demonstrating honesty, attention to detail, early communication of problems and consistent delivery.
