Position Title: SW Developer (Python), BPY0120
Duration: 6 months
Location: Onsite in Warrenville NJ
About The Role:
You'll sit at the intersection of software engineering and network infrastructure writing production-grade Python code that drives automation across a nationwide network core. You'll own the full development lifecycle of network automation tooling: from designing scalable Python frameworks and building REST/gRPC integrations, to implementing CI/CD pipelines and hardening configuration compliance across complex, multi-vendor environments.
This role is development-heavy (~90%) with meaningful exposure to real-world networking (~10 20%). You'll work shoulder-to-shoulder with network and security engineers, translating deep protocol knowledge into elegant, repeatable automation solutions.
New Jersey candidates: This is a onsite (5 days a week) opportunity, based out of Warrenville, New Jersey.
