We are looking for Network Engineering & Simulation Expert — Hephaestus candidates for a project delivered through the hiring partner.
What you'll do
- Design realistic tasks involving routing, switching, network services, segmentation, access policies, redundancy, or performance.
- Build reproducible network topologies and device configurations using relevant tools such as containerlab, GNS3, EVE-NG, Mininet, ns-3, FRRouting, or equivalent platforms.
- Configure and debug scenarios involving technologies such as BGP, OSPF, VLANs, IPv4/IPv6, DNS, DHCP, NAT, VPNs, or firewalls, within your area of expertise.
- Develop automated checks for reachability, route selection, policy enforcement, isolation, convergence, failover, latency, throughput, and packet loss. Use tests of live behavior alongside configuration inspection.
- Produce reference configurations, traffic or failure scenarios, and verification scripts; validate both successful and deliberately incorrect cases.
- Package topology files, configuration dependencies, scripts, packet captures, and results so another engineer can reproduce the outcome.
- Review AI-generated configurations and diagnose the cause of failures. Use coding agents to support automation while independently validating network behavior.
What you need
- 5+ years of professional network engineering experience, with direct ownership of enterprise, data-center, cloud, or service-provider networks.
- Strong hands-on routing, switching, troubleshooting, and network-policy skills.
- Experience building network labs, simulations, or emulations and analyzing traffic with tools such as Wireshark, tcpdump, or iperf. Familiarity with every listed platform is not required.
- Ability to write and debug Python, shell, Ansible, or comparable automation for repeatable setup and verification.
- Sound judgment about protocol behavior, failure modes, measurement limitations, and differences between simulated and production networks.
- Clear technical communication.
Nice to have
- Relevant certifications such as CCNP, CCIE, or JNCIP, and experience with network test automation, are a plus.
