You'll design high-availability architectures, industrialize operations as code, and spread reliability practices (SLOs, observability, incident management, post-mortems) across the team and the development squads. You'll also arbitrate architecture decisions on your scope and mentor junior/middle engineers, reducing recurring operational load through automation rather than manual effort. 👉Your future missions Reliability & Service Level Ownership - Guarantee availability, capacity, and performance of client platforms; own SLA/SLO commitments. - Define SLOs with development teams and arbitrate reliability vs. delivery speed on that basis.

Observability & Incident Management - Improve metrics, logs, traces, dashboards, and actionable alerting with measurable noise reduction. - Act as Incident Commander on major incidents; drive resolution, lead blameless post-mortems and remediation plans. Level 3 Support - Serve as the final escalation point for infra issues raised by support, dev, and project teams. - Surface recurring root causes upstream instead of firefighting case by case. Security, Compliance & Leadership - Integrate banking-sector security/compliance requirements into infra choices, in liaison with the CISO. - Document architectures and runbooks; mentor junior/middle engineers; lead technical reviews. - Contribute to technical hiring for the team. ⚠️ On-call required.
