About The Applicant

An experienced developer who can work independently on production systems, balancing delivery speed with long term maintainability. Cares about how things look and feel as much as how they work, and keen to learn more about cybersecurity, secure development, and building software for a hardware product.

They should be comfortable making technical decisions, raising concerns early, and proposing improvements.
