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.
