You've got real-world experience putting AI to work in businesses, and you love digging into complex technical challenges to find innovative solutions.
Details don't slip past you, and you're comfortable wading through lengthy documents and intricate code to get the full picture. As someone who picks up new skills quickly, you're energised by the fast-paced world of startups. Your entrepreneurial spirit shines through in everything you do, and you have a knack for mentoring other engineers and collaborating with both commercial teams and customers.
