You will be a collaborative member of our Core Payments Systems technology team, partnering with associates across Technology, Risk, and Business units to deliver scalable, highly available, and secure services for our clients. You will own application configuration, CI/CD, automation, incident management, performance tuning, and production support across the full software delivery lifecycle.
Key Responsibilities:

• Own platform reliability for critical applications on RHEL, targeting 99.9%+ availability.
• Build and maintain CI/CD pipelines and release automation (e.g., Jenkins, GitLab CI/CD), including artifact management, approvals, and rollbacks.
• Automate deployment, configuration, and operational tasks using Bash, Python, and configuration management tools (e.g., Ansible).
• Lead incident response: triage, root cause analysis, remediation, and post-incident learning; continuously reduce MTTR and change failure rate.
• Implement and enhance observability (logs, metrics, traces) using tools such as Splunk/Dynatrace; create actionable dashboards and alerts.
• Perform performance engineering: capacity planning, tuning (OS, JVM, MQ, DB connections), and throughput optimization.
• Manage security posture: vulnerability remediation, patching, certificate and key management, and adherence to hardening standards.
• Partner with business analysts, QA, developers, and release managers to deliver changes through the SDLC; contribute to requirements, design, testing, and documentation.
• Review solution designs for scalability, reliability, and conformance with enterprise architecture and risk controls.
• Create and maintain runbooks, standard operating procedures, and knowledge articles; mentor junior associates and lead technical design sessions.
• Participate in on-call rotation and change/release management processes (e.g., CAB), including after-hours maintenance windows when required.

Basic Qualifications:

• 8+ years supporting high-availability Unix/Linux platforms in production (RHEL, AIX, or Solaris).
• Proficiency with CI/CD tooling (e.g., Jenkins, GitLab CI/CD) and Git-based workflows.
• Strong scripting/automation skills (Bash, Python) and hands-on experience with Ansible (or Puppet/Chef).
• Experience running and optimizing SQL queries and working with relational databases (e.g., Oracle, PostgreSQL, SQL Server).
• Experience with message-oriented middleware (e.g., IBM MQ; Kafka/RabbitMQ a plus).
• Solid understanding of networking fundamentals, DNS, load balancing, TLS/PKI, and certificates.
• Observability tooling experience (e.g., Splunk/ELK, Prometheus/Grafana, AppDynamics/Dynatrace) with practical alerting/dashboards.
• Production support experience, including on-call participation and incident/problem management best practices.

Preferred Qualifications:

• Direct ACI/MTS Platform experience
