Additional Information

Company Overview Blue Silo is a technology company specialising in mission-critical, enterprise-grade software solutions for defense, government, and industrial clients. We build, deploy, and operate robust, secure, and scalable systems across both cloud and on-premises (including air-gapped) environments. To support the full lifecycle of our deployed systems, we are expanding our Operations & Engineering team with a DevOps Field Engineer. This role is central to bridging cloud-based DevOps practices with hands-on, on-site deployment and support in secure client environments where availability is non-negotiable. Role Summary The DevOps Field Engineer is responsible for the deployment, configuration, operation, maintenance, and troubleshooting of Blue Silo systems across two distinct environments: cloud-based deployments (AWS, Azure, or GCP) and on-premises, often air-gapped, client sites. The role covers both software and hardware, including application platforms, servers, networking, RFID systems, and CCTV/video systems. The engineer is the named first responder for production incidents under contracted Service Level Agreements (SLAs), and is expected to be on-site at affected client locations within 8 hours for critical issues. The role works closely with software, infrastructure, operations, and customer teams to ensure stable operations, secure deployments, and continuous improvement across development, staging, and production environments. This is a hybrid role. When DevOps and field workload is heavy, the engineer focuses on deployments, incident response, and operations. When DevOps workload is lighter, the engineer contributes as a JavaScript / Node.js developer on backend utilities, APIs, application modules, and system integrations. Candidates should be comfortable wearing both hats.
