Cuculus is looking for a hands‑on senior engineer to design, build, implement and manage secure, scalable and cost‑effective cloud and infrastructure environments for customer projects across cloud, on‑premises and hybrid platforms. Own customer environment delivery from approved architecture through cloud provisioning, Infrastructure as Code, Open Shift/Kubernetes implementation, migration, production readiness, optimization and handover. This is not a routine Production Support role;

the engineer will assist with critical customer issues requiring specialist expertise.

• Design, deploy and manage cloud infrastructure and services across AWS, Azure or equivalent platforms, including on‑premises and hybrid integrations.
