Senior Systems Engineer

At OneSpan , we specialize in digital identity and anti-fraud solutions that create exceptional and secure experiences. We are looking for a Senior System Engineer to join our team in Noida . The Senior Systems Engineer provides additional hands-on engineering capacity and end-to-end ownership for critical infrastructure, security platforms, and enterprise services. The role designs, implements, maintains, and improves resilient, secure, and supportable technology solutions across cloud and on-premises environments. Working closely with IT Infrastructure, Security, Architecture, application teams, and service owners, the engineer translates operational and project requirements into practical technical solutions and drives work from design through deployment and ongoing support. This is a delivery and ownership focused role that increases capacity across infrastructure and security initiatives, accelerates modernization, and reduces technical debt, lifecycle-management gaps, and remediation backlogs. The engineer establishes clear operational ownership, improves monitoring and recovery readiness, standardizes repeatable engineering practices, and resolves complex service issues. By expanding senior-level engineering coverage and reducing dependency on a limited number of key resources, the role enables architects and senior leaders to spend more time on architecture, governance, security, and strategic priorities rather than routine operational work. Key Responsibilities • Design, implement, and maintain critical infrastructure, security platforms, and enterprise services across cloud and on-premises environments. Convert approved requirements and architecture standards into secure, reliable, and supportable production solutions. • Take end-to-end technical ownership for assigned platforms and services, including configuration standards, documentation, monitoring, patching, upgrades, capacity planning, vendor coordination, incident support, lifecycle planning, and continuous improvement. • Increase delivery capacity across infrastructure and security initiatives by leading or executing technical work packages, resolving dependencies, coordinating testing and change activities, and completing operational handover with service owners and support teams. • Accelerate modernization and reduce technical debt by identifying aging, unsupported, overly complex, or manually administered technologies; developing practical remediation or replacement plans; and implementing standardized, automated, and maintainable solutions. • Reduce lifecycle-management and remediation backlogs by assessing platform health, prioritizing work based on operational and security risk, coordinating maintenance windows, and completing upgrades, patching, configuration remediation, and technology refresh activities. • Improve operational resilience by engineering platforms for availability, recoverability, scalability, and secure operation. Establish monitoring, alerting, backup, recovery, and failover requirements; validate procedures through testing; and address identified gaps. • Automate repeatable infrastructure and operational tasks using scripting, configuration management, infrastructure as code, and orchestration tools. Maintain version-controlled code, technical standards, reusable modules, and tested deployment and rollback procedures. • Troubleshoot complex incidents and recurring service issues using logs, metrics, traces, platform telemetry, and root-cause analysis. Implement corrective actions, document known errors and recovery procedures, and reduce repeated manual intervention. • Engineer and operate services in alignment with approved security requirements.
