The most important point: Client is not looking for a normal Application Support Engineer or Software Developer. They need someone who can build, automate, test and maintain recovery solutions for critical engineering applications. Imagine Client uses applications such as PTC Windchill and IBM ELM to manage critical engineering information. If a server fails, a datacentre becomes unavailable or a cyber incident affects these applications, Client needs a reliable way to recover the systems and their data. This engineer is responsible for making that recovery technically possible. Their main responsibilities are: 1. Application Disaster Recovery: Design and implement recovery mechanisms, failover solutions and resilient application configurations. 2. Data replication: Ensure critical application data can be replicated or recovered across separate environments, including restricted networks. 3. Application integration: Work with middleware, databases, infrastructure and networking teams to build reliable end-to-end solutions. 4. Recovery testing: Conduct disaster recovery exercises and prove that applications can be restored successfully. 5. Security and access: Implement application access controls and support compliance with defence security requirements. This is a hands-on engineering role, rather than a business continuity planning or compliance-only role., We are seeking a highly technical Application Engineer to ensure the mission-readiness, availability, and survivability of our critical engineering application suites. In this role, you will be the technical anchor for Business Continuity and Disaster Recovery (BC/DR) at the application layer. You will not just write policies; you will design, engineer, and automate failover mechanisms, fault isolation patterns, and recovery pipelines. This is a highly collaborative role requiring tight integration with our core Infrastructure, Cyber Security, and Network Engineering teams to co-design full-stack, infrastructure-supported resilience solutions capable of withstanding severe-but-plausible cyber and kinetic disruptions., * Application BC/DR Engineering: Design, build, and maintain application-layer resilience mechanisms. * Infrastructure & Network Collaboration: Partner closely with Infrastructure and Network teams to co-design resilient solutions and failover mechanisms. * Impact Tolerance & Recovery Metrics: Establish, monitor, and continuously validate Recovery Time Objectives (RTO) and Recovery Point Objectives (RPO). * Joint Resilience Drills: Participate in end-to-end, multi-team disaster recovery exercises simulating extreme scenarios, including total datacentre loss, supply chain compromises, and air-gap isolations. * Defence Compliance & Data Sovereignty: Ensure all applications and solutions strictly adhere to defence data regulations, air-gapping requirements, cryptographic mandates, and frameworks. * Implement/modify access control mechanisms and auditing to meet defined acceptance criteria.
