Network Engineer — BGP / Juniper / EVPN-VXLAN / GPU Cluster Networking

The opportunity We run our own hosting infrastructure and production network, and we’re looking for a hands-on Network Engineer who enjoys real ownership: operating core connectivity, improving reliability, and building out capabilities that directly matter to customers. You’ll work on an environment with real routing (own ASN), real datacenter networking, and meaningful change-impact. If you like being close to the technology and seeing your work show up in production immediately, you’ll fit well.

What you’ll do

Operate and improve our production network Maintain and evolve our Juniper routing and switching environment Own BGP operations on our ASN: routing policy, filtering, communities, troubleshooting, and traffic engineering Operate EVPN/VXLAN in production and help extend it as we grow Manage IPv4/IPv6 addressing and clean subnet allocation/assignment workflows

Build and mature capabilities Lead expansion into internet exchanges and peering: planning, implementation, validation, and turning it into a reliable operational capability Implement routing-security best practices (e.g., RPKI/IRR hygiene and route-leak protections) Lead the implementation of a practical DDoS mitigation approach (technology + processes + runbooks)

Documentation, observability, and operational quality Use NetBox as the source of truth for network inventory and IP addressing Improve monitoring/alerting and visibility (telemetry/logging/traffic insight) using the existing toolchain and extending it where needed Create and maintain diagrams, runbooks, and change documentation so the environment becomes easier to run over time

Be helpful beyond networking when needed When network workload is lighter, support adjacent infrastructure areas (Linux, virtualization, storage, automation, or occasional customer escalations) depending on your strengths and team priorities

What we’re looking for

Core requirements Proven experience operating production networks in a hosting/datacenter/ISP-like environment Strong practical knowledge of: BGP (policy, filtering, communities, troubleshooting) Datacenter switching and L2/L3 fundamentals IPv4/IPv6 operations and addressing design Comfortable owning production changes: planning, validation, rollback thinking, and post-change checks Fluent English (spoken and written)

Big plus Strong hands-on network security experience (firewall policy, segmentation, change discipline, rule hygiene) Experience with GPU cluster networking; RDMA in production is a strong advantage Experience extending EVPN/VXLAN designs beyond day-to-day operations Experience building DDoS mitigation workflows end-to-end Experience driving improvements in environments with low structure (you bring structure without bureaucracy)

The working style that succeeds here You stay effective when priorities shift and interruptions happen You communicate clearly during incidents and changes You take ownership and enjoy making systems more reliable, more visible, and better documented over time

Working model This is an on-site role in Hoofddorp, 5 days per week, to stay close to the hardware, platform engineering, and execution environment.
