Job description

At Sytac, we build high-performing engineering teams for leading organizations in the Netherlands and beyond. We combine a pragmatic, people-first culture with strong technical craftsmanship, giving engineers autonomy in real production environments, backed by a consultancy that invests in growth, community, and long-term partnerships.

For one of our major e-commerce clients, we are looking for a Systems & Network Engineer to strengthen their On-Prem Network (OPN) team. This team is responsible for the physical and logical network infrastructure that powers the company’s logistics, engineering operations, internal connectivity, and end-to-end platform availability. You will help build, scale, secure, and automate a critical network backbone used across offices, warehouses, cloud environments, and internal engineering teams.

This is a hybrid systems-engineering and networking role in a high-availability environment, ideal for engineers who enjoy Linux, automation, and large-scale networking.

What you’ll do

• Build, maintain, patch, and improve the on-premise network infrastructure and supporting Linux (RHEL) services
• Automate manual or semi-manual tasks (compliance, deployments, configuration) using Puppet and scripting (Bash/Python)
• Troubleshoot network issues across ISO layers 1–3 and support internal teams with incoming requests
• Manage and orchestrate network services such as DHCP, DNS, NTP, monitoring, orchestration, and supporting servers
• Contribute to major upcoming network projects in routing, switching, connectivity, and security
• Lead and coordinate network-related initiatives — upgrades, migrations, implementations — using strong project management skills
• Collaborate across engineering, warehouse operations, security teams, and vendors for seamless service delivery
• Anchor improvements by documenting changes, sharing knowledge, and embedding best practices into the team
• Ensure high availability, performance, and security of the network infrastructure supporting all business operations

What you’ll bring

Required skills

• Experience with Puppet and infrastructure automation
• Ability to troubleshoot network issues across layers 1–3
• Strong scripting ability (Bash and/or Python)
• Solid understanding of networking fundamentals and operational networking
• Excellent communication skills and experience collaborating in cross-functional teams
• Problem-solving mindset and automation-driven approach

Preferred skills

• Knowledge of routing & switching protocols (BGP, OSPF, MPLS, VXLAN, EVPN)
• Experience with network security (firewalls, VPNs) and common network services (DHCP, DNS, NTP)
• Understanding of WDM, KVM, InfluxDB/Telegraf, or Golang
• Experience with large-scale or multi-site network environments (warehouses, datacenters, offices, cloud)

About the team

The team manages the end-to-end network backbone that supports the company’s core operations. It’s a collaborative, experienced group working on high-impact projects, with shared ownership over stability, reliability, and continuous improvement.

Hardware & tooling used include:

• Cisco & Juniper networking hardware
• Puppet & Python for automation and orchestration
• RHEL servers providing network services (monitoring, DHCP, DNS, NTP, orchestration)

Why this role fits you

• You love systems engineering with a strong affinity for networking
• You enjoy automating manual work and making infrastructure more reliable and scalable
• You appreciate large, distributed network environments that span warehouses, datacenters, cloud, and offices
• You like combining hands-on engineering with project coordination and stakeholder communication

What we offer

• A high-impact engineering role supporting the network infrastructure of one of the Netherlands’ largest e-commerce platforms
• The opportunity to work in a technically challenging environment with modern networking and automation tooling
• Collaboration with experienced network specialists eager to share knowledge
• A culture focused on ownership, reliability, and continuous improvement
• Access to Sytac’s engineering community, learning sessions, and professional development support
