Software Engineer- Java |8 to 14yrs| Bangalore

Cisco; Bengaluru; Vor Ort; INR 4.000.000 - 6.500.000; Vollzeit

Zusammenfassung

Cisco Optical Network Controller (CONC) team leads the industry in optical SDN controller solutions, powering mission-critical tier-1 service provider networks globally. We develop cloud-native, distributed microservices capable of high-throughput network control and state synchronization.

Senior Engineers drive architectural excellence in Java microservices and automated validation frameworks in Python. This role shapes design, testing, and performance across Kubernetes deployments and complex

Qualifikationen

• Bachelor's or Master's in CS/ECE/EE with 6 to 9+ years of progressive experience designing and developing distributed enterprise or networking software.
• Advanced Java mastery: Spring Boot / Micronaut, concurrency/multithreading, distributed data caching, transactional consistency, and REST/gRPC API design.
• Python test engineering: modular, automated Python test frameworks (PyTest, Robot Framework, mock servers) for large-scale topologies.
• Cloud-native & distributed systems: Kubernetes, Docker, Kafka, distributed state management, and Linux internals.

Aufgaben

• Lead the design and implementation of complex, resilient Java microservices for topology discovery, service provisioning, circuit path computation, and lifecycle management.
• Architect scalable Python test automation frameworks; mentor engineers on writing robust end-to-end tests for distributed edge cases.
• Profile, troubleshoot, and optimize microservice performance, concurrency, and memory footprint in containerized Kubernetes clusters.
• Drive rigorous code reviews, test-driven development (TDD), automated regression guardrails, and onboarding for junior engineers.
• Partner with Product Leads and Architects to ensure carrier-grade reliability and rapid turnaround on critical customer escalations.

Your Impact

• Technical Design & Architecture: Lead the design and implementation of complex, resilient Java microservices for topology discovery, service provisioning, circuit path computation, and lifecycle management.
• Dev-Test Architecture & Strategy: Architect scalable, reusable Python test automation frameworks; mentor engineers on writing robust end-to-end tests for distributed edge cases (e.g., node failover, high availability, scale).
• Performance & Scale Optimization: Profile, troubleshoot, and optimize microservice performance, concurrency, and memory footprint in containerized Kubernetes clusters.
• Code Quality & Mentorship: Drive rigorous code reviews, test-driven development (TDD), automated regression guardrails, and technical onboarding for junior engineers.
• Release & Customer Quality: Partner with Product Leads and Architects to ensure carrier-grade reliability and rapid turnaround on critical customer escalations.

Minimum Qualification

• Education & Experience: Bachelor's or Master's in CS/ECE/EE with 6 to 9+ years of progressive experience designing and developing distributed enterprise or networking software.
• Advanced Java Mastery: Deep expertise in Java (Spring Boot / Micronaut), concurrency/multithreading, distributed data caching, transactional consistency, and REST/gRPC API design.
• Python Test Engineering Expertise: Extensive experience designing modular, automated Python test frameworks (PyTest, Robot Framework, mock servers) to simulate large-scale network topologies and microservice interlocks.
• Cloud-Native & Distributed Systems: Strong experience with Kubernetes, Docker, Kafka, distributed state management, and Linux systems internals.

Preferred Qualification

• Deep domain experience in Optical Networking (ROADM, Transponders, OTN, DWDM), L0-L3 network topologies, or PCE/Path Computation algorithms.
