Job Description As a Cyber Resilience Senior Engineer, you will be responsible for strengthening the organization’s ability to anticipate, withstand, recover from, and adapt to cyber incidents and other disruptive events. Your primary focus will extend beyond traditional disaster recovery to include designing and implementing resilience strategies that maintain the continuity, integrity, and availability of critical IT services under adverse conditions. You will develop and enhance resilience capabilities such as redundancy, automated failover, immutable backups, cyber‑recovery architectures, and continuity-by-design patterns. You will also lead exercises and simulations to validate resilience posture, identify weaknesses, and drive continuous improvement across systems and processes. Collaboration is central to this role. You will work closely with architects, system engineers, security teams, and operational leaders to identify critical business services, understand their dependencies, assess resilience gaps, and design strategies that reduce the impact of disruptions. You will also partner with business stakeholders to ensure resilience objectives align with organizational priorities and regulatory expectations. To be successful, you should have deep experience in cyber resilience and continuity engineering, including modern cloud‑native resilience patterns, backup and recovery solutions, replication and failover strategies, zero‑trust‑aligned recovery approaches, and containerized or distributed service architectures. Strong project leadership skills are essential, as you will coordinate resilience initiatives across multiple teams and environments. Additionally, you should have excellent communication and stakeholder‑management skills, as you will be responsible for guiding teams through resilience planning, readiness assessments, and incident response activities.
