• This is not a maintenance job. You will be the technical lead on that modernization, not a support resource.
• You will work on a small, focused team.
• That means you own what you build. You will design it, build it, test it, deploy it, document it, and support it in production.
• If you need someone to hand you tickets and watch over your shoulder, this is the wrong role.
