The role provides hands-on technical ownership of the physical network, firewalls, Wi-Fi, virtualization hosts, shared storage, backup and restoration, monitoring platforms, and Microsoft 365 and Microsoft Entra ID services. As Stellar scales, this position is expected to independently assess the current environment, identify operational and security risks, define improvement and remediation plans, and implement the agreed actions. The role combines strong systems and network engineering expertise with disciplined execution, documentation and a service-oriented mindset. Scope note: day-to-day administration of guest operating systems and hosted applications remains outside the primary scope of the position. However, the engineer is expected to assess their infrastructure and security dependencies and work with the relevant owners to identify and implement required improvements., As Infrastructure & Network Engineer, you will operate, maintain, secure, monitor and improve Stellar's infrastructure across the following areas: * Network, Wi-Fi & Firewall Security Own the availability, security, performance and configuration of Stellar's network, firewalling and Wi-Fi across sites and network segments. Operate and maintain network switches, routing and VLAN/trunk segmentation across corporate, customer, laboratory and infrastructure networks. Operate and maintain Wi-Fi access points and controllers, including Wi-Fi 6, corporate and guest networks, and maintain the IPv4/IPv6 addressing plan and internal DNS. Operate and maintain core, local and cloud firewalls, including filtering rules, DMZs, blocklists, remote-access VPNs and firewall high availability. Manage the certificate lifecycle for internal services and FQDNs, and apply network and infrastructure security best practices. * Security Assessment & Risk Remediation Perform structured security assessments of infrastructure, identity services, applications and service dependencies; identify vulnerabilities and operational risks; define remediation plans; and implement and track approved actions. * Identity & Access - Microsoft 365 / Microsoft Entra ID Operate and maintain Microsoft 365 and Microsoft Entra ID, including identity and access management, role and privilege reviews, authentication controls, user lifecycle processes and security configuration. * Virtualization, Storage & Backups strategies Operate and maintain the virtualization host cluster, including hosts, high availability, heartbeat, cluster networking, virtual networks, SDN/VXLAN and cluster trunks, and contribute to the evolution of the architecture. Operate and maintain NAS and storage volumes, including shares, NFS protocols, capacity, integrity, throughput and performance. Implement, operate and supervise on-site and off-site backup solutions; define backup policies; execute regular restore tests; and maintain clear recovery procedures and evidence. * Monitoring & Observability Design, implement and operate monitoring and observability using Zabbix, Grafana and Elastic Stack, complemented by SNMP and IPMI where appropriate. Define service and infrastructure indicators, dashboards, alerting thresholds and escalation rules to anticipate incidents and support capacity, availability and performance management. * Incident & Request Management, Reporting Handle requests and incidents through the ticketing platform, perform root-cause analysis where appropriate, apply firmware updates and security patches, and resolve infrastructure issues. * Documentation & Continuous Improvement Maintain accurate inventory, network diagrams, configurations, technical documentation, operating procedures and recovery documentation. Produce a monthly activity report covering incidents, requests, availability, capacity, monitoring, backup and restore tests, patching, security risks and improvement actions. Identify, prioritize and implement infrastructure improvement opportunities in alignment with operational, security, scalability and business requirements. Overall, contribute positively to Stellar's collaborative, international and results-oriented culture. ## Related Videos - [IP Authentication: A Tale of Performance Pitfalls and Challenges in Prod](https://www.wearedevelopers.com/videos/1413-ip-authentication-a-tale-of-performance-pitfalls-and-challenges-in-prod) - [What makes Cybersecurity different for critical infrastructure?](https://www.wearedevelopers.com/videos/571-what-makes-cybersecurity-different-for-critical-infrastructure) - [WebAssembly: The Next Frontier of Cloud Computing](https://www.wearedevelopers.com/videos/972-webassembly-the-next-frontier-of-cloud-computing) - [IoT: The road to sustainability](https://www.wearedevelopers.com/videos/557-iot-the-road-to-sustainability) - [Generating code with Angular schematics](https://www.wearedevelopers.com/videos/129-generating-code-with-angular-schematics) - [Unlocking the potential of Digital & IT at Vodafone](https://www.wearedevelopers.com/videos/602-unlocking-the-potential-of-digital-it-at-vodafone) ## Related Articles - [Best Companies in the Netherlands: Top 25 Companies in 2023 ](https://www.wearedevelopers.com/magazine/193-best-companies-in-the-netherlands-top-25-companies-in-2023) - [Is Software Engineering Over-Saturated?](https://www.wearedevelopers.com/magazine/418-is-software-engineering-over-saturated) - [Why Upskilling And Reskilling is Important For Developers](https://www.wearedevelopers.com/magazine/428-why-upskilling-and-reskilling-is-important-for-developers) - [Where to Find Entry-Level Software Engineering Jobs](https://www.wearedevelopers.com/magazine/397-where-to-find-entry-level-software-engineering-jobs) - [The Most Popular IT Jobs on the Market](https://www.wearedevelopers.com/magazine/376-the-most-popular-it-jobs-on-the-market) - [How to land a developer job in Amsterdam](https://www.wearedevelopers.com/magazine/36-how-to-land-a-developer-job-in-amsterdam)
