Meet the team:

The Cisco Optical Network Controller (CONC) team is building next-generation SDN software to automate, visualize, and control optical networks across multi-layer infrastructures. Our solution is built on modern, cloud-native microservices architecture. In our team, engineers have end-to-end quality and feature ownership: we build the software and we automate the testing ourselves, writing robust backend services in Java and automated test suites in Python.

Your Impact:

Microservices Development: Design, implement, and maintain scalable microservices in Java (Spring Boot / REST / gRPC) for optical network management and control plane workflows.

• Full Dev-Test Ownership: Write comprehensive unit, integration, and end-to-end automated tests in Python (PyTest, custom test harnesses) as part of your day-to-day feature deliverables.

• Continuous Integration: Integrate automated Python test suites into CI/CD pipelines (Jenkins / GitLab CI) to guarantee zero regression and rapid release cycles.

• Collaborate & Deliver: Work closely with Technical Leads, Product Managers, and team members in an Agile Scrum model to deliver resilient, production-ready software.

 
Minimum Qualifications:

Education & Experience: Bachelor's or Master's in Computer Science, Computer Engineering, Electrical Engineering, or related discipline with 1 to 3 years of hands-on software development experience.

• Core Java Skills: Strong foundation in Core Java , OOP design patterns, data structures, and building RESTful microservices.

• Python Automation Skills: Practical experience writing clean, maintainable Python automation scripts/test suites for API, integration, and functional validation.

• Containers & Orchestration: Hands-on familiarity with Docker, containerized deployments, and basic Kubernetes.

• Database & Messaging: Working knowledge of relational/NoSQL databases and messaging systems (e.g., Kafka, RabbitMQ).

• Mindset: Strong quality-first mentality with a proactive attitude toward diagnosing and resolving automated test failures.

Preferred Qualifications

Familiarity with Optical Networking / SDN concepts, YANG data modeling, or NETCONF/RESTCONF protocols
