About the role

Key responsibilities & impact

Automate the cloud. Write the Ansible playbooks that provision infrastructure and stand up network services across AWS, Azure, and GCP — VPCs/VNets, subnets, tunnels, NAT, routing, and security policy.
Build the engines. Develop the Go task engines that push this configuration onto the CXP nodes at scale — running provisioning and teardown against live state, and rebuilding a node’s entire configuration after a controlled restart.
Bring up new capabilities. Integrate new VNFs as we light up new services and capabilities.
Own the tooling. Build the Python tooling and CLI engineers use to inspect, configure, and debug the networking stack on the nodes.
Model the work. Extend the configuration and task models that translate a single provisioning request into the exact commands applied on the nodes.
Keep it fast and correct. Help connectivity stay correct, fast, and reliable across clouds and at scale.
Solve real problems. Chase tricky production provisioning issues to their root cause and drive the fix — and collaborate with Routing, Data Path, and Backend on how configuration flows end to end.

Requirements

What you’ll need

Strong software fundamentals — data structures, problem-solving, clean code, and the patience to debug.
Hands-on coding in at least one of C, Python, or Go, and the appetite to pick up the others — we use all three everyday, and the engineers who range across them go furthest.
Comfort on Linux — the shell, processes, logs, and the everyday networking tools.
Hands-on familiarity with core networking — TCP/IP, and the curiosity to go deeper.
A working mental model of the cloud — at least one of AWS, Azure, or GCP: what a VPC/VNet, subnet, and security group actually are.
A debugging mindset — you genuinely enjoy chasing a problem until you find the real cause.
Bonus Points Ansible or other configuration-automation experience.
