We are building a new internal application development platform for a leading global bank. The goal is to give developers an experience at least as good as market solutions such as Heroku or Coolify within a regulated enterprise environment.

• Turn developer pain points into shipped improvements, either by building the fix or by driving it to the owning team and tracking it to resolution

• Collaborate with product, engineering, architecture and risk/control teams
