• Runtime safety: Enforce runtime security, secrets management, image hygiene, and compliance controls integrated “shift-left” into build and deploy workflows.
• Algo-trading runtime: Operate and optimize Deltix-based components (Timebase DB, Ember, Strategy Server) in containerized, high-availability setups. Own the corresponding Helm charts.
