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.

Key Responsibilities:

Service Level Ownership & Incident Response:

Act as the named first responder for production incidents on assigned client systems under contracted SLAs.
Attend the affected client site within 8 hours for critical (Severity 1) incidents, and within agreed timelines for lower severities.
Participate in an on-call rotation, including evenings, weekends, and public holidays as required by client SLAs.
Lead diagnosis, mitigation, and resolution of incidents; own root cause analysis and post-incident reviews.
Coordinate escalation to the remote development team, vendors, and system integrators where required.

Cloud Deployment & Devops:

Deploy, configure, and maintain applications and supporting infrastructure on a major cloud platform (AWS, Azure, or GCP) across development, staging, and production environments.
Design, implement, and maintain CI/CD pipelines for automated build, test, and release management.
Implement Infrastructure as Code (IaC) using tools such as Terraform or CloudFormation for reproducible environment builds.
Support containerised deployments using Docker, Kubernetes, or equivalent orchestration platforms.
Implement and manage cloud-native monitoring, logging, and security services.

On-Premises & Air-Gapped Site Deployment:

Perform on-site installation, commissioning, integration, and operational readiness activities at client premises, including air-gapped and security-controlled facilities.
Manage offline software distribution, patching, and dependency mirroring for environments without internet access.
Administer Linux and Windows server environments, virtualisation platforms (VMware, Hyper-V), and physical/virtual networking.
Implement and verify backup, replication, and disaster recovery jobs (Veeam or equivalent).
Monitor system health and performance using tools such as Zabbix, addressing alerts proactively.

Hardware & Integrated System Support:

Configure, test, and troubleshoot RFID devices, readers, antennas, and associated middleware; support RFID asset-tracking integration with applications.
Configure and maintain CCTV cameras, Network Video Recorders (NVR), Video Management Systems (VMS), and related network components.
Troubleshoot connectivity, streaming, storage, recording, and hardware-related issues across integrated systems.
Support integration between RFID/CCTV systems and operational workflows where applicable.

Documentation, Compliance & Knowledge Custodianship:

Maintain comprehensive technical documentation: runbooks, architecture diagrams, configuration records, troubleshooting guides, and incident logs.
Ensure operational procedures and configurations comply with project, client, and security requirements.
Support audit, inventory, and asset management activities.
Translate operational insights into updated documentation, automation, and preventive improvements.

Required Qualifications:

2+ years of hands-on experience in a DevOps, site reliability, system administration, field engineering, or software development role. Direct experience supporting production systems under SLA is a strong plus but not mandatory.
Working experience or solid project exposure with at least one major cloud platform (AWS, Azure, or GCP) — deploying, configuring, or operating systems.
Comfort working on customer premises, including environments with restricted or no internet connectivity. Prior on-site deployment experience is preferred but not required.
Working knowledge of Linux and Windows Server administration.
Familiarity with networking fundamentals: TCP/IP, VLAN, routing, firewall, and switch configuration.
Exposure to CI/CD pipelines, Docker, and Infrastructure as Code (Terraform or equivalent); willingness to deepen these skills on the job.
Familiarity with system monitoring tools (Zabbix preferred) and backup/recovery concepts (Veeam or equivalent).
Strong analytical and troubleshooting skills across both hardware and software.
Excellent written and verbal communication skills; able to work effectively with clients, developers, and vendors under pressure.
Willingness and ability to be on-site at client locations within 8 hours for critical incidents, including outside standard business hours; valid driving licence and own transport preferred.
Eligibility to work on defense, government, or other security-sensitive projects, including any clearance, vetting, or background-check requirements specified by the client.

Preferred Qualifications:

Diploma or Degree in Computer Engineering, Information Technology, Computer Science, Software Engineering, or a related discipline.
Experience with RFID systems, asset tracking, or related hardware integration.
Experience configuring and troubleshooting CCTV systems, IP cameras, NVRs, and VMS platforms.
Experience supporting mission-critical or operational technology (OT) systems in defense, government, or industrial settings.
Experience with container orchestration (Kubernetes) and configuration management (Ansible).
Certifications in cloud platforms (AWS / Azure / GCP), Linux, Kubernetes, networking, or ITIL.
Familiarity with documentation and collaboration tools (Confluence, SharePoint, or similar).

What We Offer:

A foundational role in Blue Silo's Operations & Engineering team, with direct impact on client outcomes.
Exposure to both modern cloud platforms and high-stakes on-premises environments.
Backing from an experienced development team for complex troubleshooting and escalations.
Competitive compensation, on-call allowance where applicable, and professional development support.
