Original job description

Job Summary

Designs, develops, implements, and supports automation capabilities for middleware platforms and services. Works closely with application, infrastructure, security, and operations teams to deliver scalable, secure, reliable, and repeatable solutions using Kubernetes, Ansible, and API Gateway technologies. This role provides senior-level engineering leadership: promotes configuration as code, platform standardization, self-service, and continuous improvement across cloud, container, and traditional middleware environments.

Primary Activities and Responsibilities

Design, develop, test, and maintain reusable automation solutions for middleware provisioning, configuration, deployment, patching, upgrades, validation, and operational support.
Develop Ansible playbooks, roles, inventories, templates, and workflows using Ansible Automation Platform to standardize middleware lifecycle management.
Deploy, configure, and support middleware workloads on Kubernetes and Red Hat OpenShift, including namespaces, deployments, services, routes or ingress, configuration, secrets, storage, and resource policies.
Develop and maintain Helm charts, Kubernetes manifests, and Argo CD application configurations for repeatable GitOps-based application and middleware deployments.
Configure and support API and/or AI Gateway capabilities
Integrate middleware automation with CI/CD and GitOps workflows using source control and delivery platforms such as GitHub, Jenkins, and Argo CD.
Build configuration-as-code and infrastructure-as-code patterns that are secure, reusable, version controlled, and suitable for deployment across multiple environments.
Collaborate with application, cloud, network, database, cybersecurity, and production support teams to translate technical requirements into automated solutions.
Implement automated health checks, post-deployment validation, monitoring, alerting, and remediation for middleware platforms and services.
Troubleshoot complex deployment, connectivity, certificate, configuration, performance, and integration issues across containerized and traditional middleware environments.
Create and maintain technical documentation, operational procedures, architecture diagrams, support runbooks, coding standards, and reusable automation patterns.
Participate in platform reliability, capacity planning, disaster recovery, vulnerability remediation, root cause analysis, and service restoration activities.
Evaluate emerging platform engineering and automation capabilities and recommend improvements that reduce manual effort, deployment risk, and operational complexity.
Miscellaneous activities and responsibilities assigned by the manager.

Minimum Qualifications

Bachelor's degree from an accredited institution in Computer Science, Information Systems/Technology, Engineering, or a related field of study.
5 or more years of experience in middleware engineering, systems engineering, platform engineering, DevOps, infrastructure automation, or related technology roles.

Strong experience developing automation with Ansible and Ansible Automation Platform, including playbooks, roles, collections, inventories, credentials, templates, and workflows.
Experience with enterprise API Gateway or API management platforms and related API security and traffic-management policies.
Knowledge of Argo CD concepts and operations, including applications, projects, synchronization policies, health status, configuration drift detection, RBAC, Helm or Kustomize integration, and multi-cluster GitOps delivery.
Knowledge of REST APIs, JSON, YAML, HTTP/HTTPS, TLS, certificates, OAuth 2.0, OpenID Connect, mTLS, and service-to-service integrations.
Experience with Git-based development practices, pull requests, branching strategies, CI/CD pipelines, testing, and release automation.
Experience with Terraform, including reusable modules, variables, providers, state management, plan and apply workflows, and infrastructure provisioning through CI/CD pipelines.
Knowledge of Linux administration, networking, DNS, load balancing technologies such as Citrix NetScaler, firewalls, proxies, observability, and secure credential management.
Ability to diagnose complex issues using platform logs, application logs, Kubernetes events, API Gateway traces, network tests, and monitoring data.
Ability to communicate fluently orally and in writing and present technical information to both technical and non-technical audiences.
Ability to work independently, collaborate across teams, prioritize competing work, and rapidly apply new technical information.
