You’ll make the technical calls on trade-offs, help other engineers grow through code review, pairing and mentoring, and work closely with security, risk and product teams to build reliability and security in from the start. You’ll also present regularly at showcases, from technical deep-dives for other engineers to walking the wider company through what your team has shipped
