We are seeking a seasoned Test Principal Engineer to lead the validation strategy for our DOCSIS-based broadband access systems. This role demands deep technical expertise in DOCSIS technologies, distributed systems, and enterprise-grade software platforms. You will collaborate with cross-functional teams to ensure the reliability, scalability, and security of our element management systems.

Key Responsibilities:

• Lead the planning, design, and execution of test strategies for DOCSIS-based broadband access systems and element management platforms.
• Collaborate with cross-functional engineering, product, and support teams to ensure test coverage aligns with system architecture and business goals.
• Develop and maintain automated test frameworks for validating distributed, multi-tiered applications, including FCAPS functionalities.
• Drive performance, scalability, and reliability testing across geographically distributed systems with high concurrency and multi-threading.
• Ensure robust validation of REST APIs, SNMP, IPFIX, Netconf/Yang, and database interactions (Postgres, MongoDB).
• Oversee testing of HA, clustering, and redundancy features to ensure fault tolerance and system resilience.
• Recreate and simulate complex system issues in test environments that closely mirror customer deployments to ensure accurate troubleshooting and validation.
