Founding Engineer
Founding engineers carry an unusually broad remit — they write production code, interview candidates, present technical strategy to investors, and set the engineering culture from day one. Success depends on switching fluently between the precise language of system design and the persuasive register of investor updates, hiring pitches, and build-vs-buy memos. This path builds the advanced professional English required to operate at that intersection of technical depth and organisational leadership.
