The Senior Analyst partners closely with engineering, Infrastructure, DevOps, and architecture teams to ensure applications are operable by design, resilient, and scalable. You will lead efforts in advancing continuous delivery/deployment (“CI/CD”) pipelines, automation frameworks, and DevOps practices, while ensuring consistent adoption of ITIL[TY2] -aligned processes (change, configuration, release, and problem management). This role plays a key part in improving platform reliability, reducing operational risk, and driving automation-led efficiency across environments. ## Responsibilities - Lead and standardize platform administration practices across applications, defining operational patterns and improving consistency and operational readiness across environments. - Define and enforce configuration management standards, ensuring integrity, consistency, and auditability of application environments across development, test, and production. - Design and standardize CI/CD pipelines, establishing best practices for automated deployments and environment orchestration and release standardization. - Architect and implement automation frameworks to eliminate manual processes and improve deployment and operational efficiency at scale. - Manage and govern complex deployments, upgrades, and patching activities, including release planning, sequencing, rollback strategies, and validation of production readiness. - Provide leadership over environment health, performance, and integration stability, driving proactive risk mitigation and ensuring operability, automation, and observability are embedded across application design and delivery. - Lead advanced troubleshooting of platform, configuration, and integration issues, leveraging deep expertise in logs, data flows, and system architecture. - Drive systemic root cause elimination and implement structural improvements to prevent recurring platform issues. - Act as a key contributor to DevOps and operational maturity initiatives, influencing best practices for environment management, observability, automation, and release engineering. - Define and enhance monitoring, alerting, and observability practices to improve visibility into platform health, performance, and integration stability. - Continuously improve and optimize ITIL-aligned processes to enhance operational efficiency and risk management. - Collaborate with engineering and architecture teams to ensure operability, scalability, and supportability are embedded into system design and delivery pipelines. - Maintain and continuously evolve operational standards and documentation, including runbooks, configuration baselines, deployment models, and automation frameworks. - Mentor and guide Associate and Base-level analysts, providing technical leadership and promoting consistent administrative standards and best practices. - Drive continuous improvement initiatives to enhance platform stability, reduce operational overhead, and standardize administration practices across the organization. - Other duties as assigned. ## Qualifications - Bachelor’s degree in Information Systems, Computer Science, Business, or a related field preferred, or equivalent relevant professional experience. - 5+ years of experience in application administration, middleware platform operations, or DevOps-oriented roles. - Proven expertise in middleware platforms (e.g., MuleSoft, Tomcat, WebLogic and ODI) and strong understanding of application integrations and distributed system architectures. - Demonstrated experience designing and managing CI/CD pipelines, deployment automation, and release engineering practices. - Hands-on experience with automation and scripting (e.g., Shell, Python, PowerShell, or similar) to optimize platform operations and reduce manual effort. - Strong understanding and practical application of ITIL frameworks, including change management, configuration management, release management, and problem management. - Demonstrated ability to own platform stability and drive root cause elimination, with a proactive and prevention-focused operational mindset. - Experience operating in complex enterprise environments with multiple applications, integrations, and dependencies. - Strong analytical and troubleshooting skills, with the ability to diagnose and resolve complex cross-system and configuration issues. - Ability to influence and collaborate with cross-functional teams (engineering, DevOps, architecture) to drive operational improvements and standards. - Strong communication and documentation skills in English, with the ability to clearly articulate technical concepts, operational standards, and governance practices. ## At a glance - Posted by the employer: Oct 5, 2026 -
