Job Overview

We are seeking experienced and technically proficient IBM DataPower Administrators to implement, configure, administer, secure, monitor and support IBM DataPower Gateway environments within complex enterprise IT infrastructures.

The successful candidates will be responsible for ensuring the availability, security, reliability and performance of enterprise integration gateways, including SSL/TLS certificate management, network connectivity, appliance administration, operating system integration and API security.

This role requires substantial hands‑on experience with IBM DataPower Gateway, SSL/TLS, PKI, digital certificates, network protocols, enterprise security controls, gateway troubleshooting and production support.

The ideal candidates will have proven experience supporting IBM DataPower appliances or virtual deployments within large enterprise environments, including secure application integration, web services, API traffic management, certificate lifecycle administration and high‑availability configurations.
