Collaborate in a scrum team, crafting solutions and delivering new features. Own the design and delivery of critical services, from architecture decisions through to production support, with autonomy to influence technical direction.  Help automate deployment, upgrades, and maintenance using modern DevOps techniques.  Participate in a well-structured on-call rotation focused on sustainability, automation, and preventing repeat incidents — not heroics.
