- 3+ years of professional software development experience, including experience 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.
- Familiarity with CI/CD processes, automated testing, and modern software delivery practices.
- Experience working with Docker or similar containerization technologies.
- Experience debugging applications, investigating software issues, and implementing fixes.
- Strong analytical and problem-solving skills, attention to detail, and the ability to work effectively within a collaborative engineering team.
- Ability to independently complete well-defined development tasks and contribute to moderately complex technical projects.
Preferred Qualifications- Experience developing gRPC services using Protocol Buffers (Protobuf).
- Hands-on experience with Cisco Network Services Orchestrator (NSO), including Python APIs, service packages, or YANG models.
- Experience with GitLab CI/CD and Docker Swarm.
- Familiarity with network automation technologies and protocols such as NETCONF, RESTCONF, SSH, and YANG.
- Understanding of networking fundamentals, including TCP/IP, routing, switching, VLANs, MPLS, and BGP.
- Experience with network provisioning, configuration management, or service activation systems.
- Familiarity with distributed systems concepts such as service-to-service communication, asynchronous processing, retries, and error handling.
- Experience with Linux systems and command-line tools.
- Familiarity with logging, monitoring, metrics, and application troubleshooting.
