The PoC and solution design are ready &mdash; your job is to take it into production. The platform runs on a modern container-based environment, with strict requirements around security, authentication and integration. The setting is technically complex and stakeholder-rich: you&#8217;ll work closely with the Technical Platform Lead, Solution Architect, an internal API gateway team and adjacent platform teams.
