We are seeking an infrastructure engineer who owns a real on-premises estate and is comfortable stepping into cloud and automation work when the team needs it.

This is not a cloud-native DevOps role. The core of the job is networking, firewalls, virtualization, and storage across multiple datacenters. Cloud, Terraform, and CI/CD sit alongside that as a valuable second skill set rather than the main event. You will work day-to-day alongside the product infrastructure manager, take real ownership of projects, and act as the technical escalation point for infrastructure incidents.

About First Factory

We are a software development company with over two decades of experience, boasting a dynamic team of 175+ professionals actively engaged in diverse projects across various industries. We invite you to join us on this journey as we thrive and embrace fresh challenges.

Key Responsibilities

• Configure, maintain, and troubleshoot the network estate: Cisco switches and routers (Catalyst series), firewalls including HA clusters, SD-WAN, IPsec VPN tunnels, datacenter switching (Mellanox experience a plus), and diagnose ISP circuit-level issues to manage carrier fault tickets.

• Harden and secure the infrastructure: lock down switch and device management, control VPN access, and keep external actors out of the estate.

• Administer VMware vCenter and ESXi environments across multiple sites using PowerShell and PowerCLI for automation.

• Administer storage arrays (provisioning, performance monitoring, troubleshooting; Pure Storage, Dell SAN, or Storage Spaces Direct) and own backup and disaster recovery workflows, including restores using Nakivo, Wasabi, and Rclone.

• Manage server hardware lifecycles remotely: firmware, hardware diagnostics, vendor/lease relationships, and directing colocation remote hands for replacements, power cycling, and console access.

• Own SSL certificate renewal and deployment back onto platforms and network devices.

• Implement and maintain monitoring coverage, alerting, and dashboards for legacy and cloud infrastructure using LogicMonitor and Datadog.

• Provision and maintain AWS infrastructure (EC2, ECS Fargate, RDS, VPC, IAM, SNS, Systems Manager, Secrets Manager, WAF, Route 53, S3) and keep connectivity between on-premises data centers and the cloud secure and reliable.

• Write, review, and maintain Infrastructure as Code (IaC) using Terraform for AWS, VMware, and network configurations; develop CI/CD pipelines in GitHub Actions (YAML, OIDC).

• Serve as a technical escalation point for infrastructure incidents, driving full-stack troubleshooting across network, storage, virtualization, cloud, and application layers.

• Join the on-call rotation, take ownership of alerts end-to-end, and advise the development team on infrastructure/platform architecture.

Requirements

• Proficiency with Cisco switching and routing (Catalyst series), VLAN configuration, and routing protocols.

• Hands-on firewall configuration experience (FortiGate preferred; Cisco ASA, Palo Alto, or comparable platforms welcome).

• Practical experience administering storage arrays, RAID levels, and disk layouts (Pure Storage, Dell SAN, or Storage Spaces Direct).

• Solid background managing VMware environments (vCenter, ESXi).

• Experience owning backup and DR: retention, rotations, offsite copies, and restores you have actually performed.

• Experience managing physical server estates, firmware/hardware diagnostics, and directing third-party remote hands.

• Strong AWS administration skills (EC2, ECS Fargate, RDS, VPC, IAM, SNS, Systems Manager, Secrets Manager, WAF, Route 53, S3) with a working knowledge of Azure.

• Ability to configure end-to-end monitoring, alerting, and custom dashboards (LogicMonitor, Datadog, or comparable).

• Judgment to read scripts, understand blast radius, and validate before running against production.

• Highly self-directed with a proven ability to take full ownership of complex technical problems through to resolution without close supervision.

• Sharp troubleshooting instincts across network, virtualization, storage, cloud, and application layers.

• Clear written and verbal English communication skills for technical documentation, status updates, and vendor management.

Nice to have

• Terraform and Infrastructure as Code (AWS, VMware estate, firewall/switch configs in GitHub).

• CI/CD pipeline work in GitHub Actions: deployment/workflow YAML and OIDC connections between GitHub and AWS.

• Containerization and orchestration (ECS/Fargate; Kubernetes experience translates directly).

• PowerShell, PowerCLI, and Bash scripting for VMware and operational automation.

• Mellanox datacenter switching experience.

• Specific backup tooling experience: Nakivo, Wasabi (S3-compatible cloud storage), and Rclone.

• Basic Postgres administration (database/user creation, backup/restore, identifying long-running queries).

• Production on-call and incident management experience.

• Jira and Confluence for ticketing and documentation.

• Experience with managed hosting platforms and migrating workloads off them into AWS.
