About The Position

Zayo Group is seeking a Software Engineer II for its Network Automation Software Engineering team. The team develops and maintains software platforms, microservices, and automation solutions for provisioning, configuring, and managing Zayo’s telecommunications network infrastructure. The role designs, develops, tests, and maintains software that automates network operations and improves the efficiency and reliability of service delivery. Work primarily uses Python to develop microservices that communicate through gRPC APIs defined with Protocol Buffers, and Cisco Network Services Orchestrator (NSO) to automate network device configuration and service provisioning. The engineer works across teams, contributes to technical design, and owns assigned software development tasks and features. The position participates in an Agile development environment and collaborates with software engineers, network engineers, product stakeholders, and operations teams. It also supports production microservices, CI/CD and deployment workflows, code quality, documentation, and ongoing improvements. The estimated base salary range is $89,800–$138,200 USD annually. This position is not eligible for employment-based visa sponsorship.

Requirements

Bachelor’s degree in Computer Science, Software Engineering, Computer Engineering, or a related field, or equivalent practical experience.
At least 3 years of professional software development experience, including developing, testing, and maintaining production applications.
Proficiency in Python, including object-oriented programming, common Python libraries, and software development best practices.
Experience developing or integrating APIs and backend services.
Familiarity with microservices architecture and distributed application concepts.
Understanding of software design principles, data structures, and common programming patterns.
Experience using Git-based source control and collaborative development workflows.
