Job Description

Role Name: DevQA Engineer – RDK-B / Broadband Networking
Work Location: Santa Clara, CA (Onsite)
About the Role
We are seeking an experienced DevQA Engineer with strong expertise in broadband networking and embedded platforms to ensure quality across RDK-B-based gateway and extender products.
This role focuses on end-to-end system validation, test automation, and performance assurance for complex networking features rather than direct feature development.
The ideal candidate will work closely with software developers, platform architects, and chipset vendors to ensure high reliability, scalability, and customer-grade performance in production environments.
Required Skills & Experience:
  • 3+ years of experience in DevQA, System QA, or Validation Engineering for embedded or networking products.
  • Strong understanding of RDK-B, OpenWRT, or prplOS-based systems.
  • Solid experience with embedded Linux, including log analysis, process monitoring, memory usage, and crash debugging.
  • In-depth knowledge of TCP/IP networking concepts, including:
    • Packet flow and forwarding paths.
    • Routing and bridging.
    • Multicast, Quality of Service (QoS), and traffic prioritization.
  • Hands-on experience testing IPv6 technologies and IPv4/IPv6 coexistence.
  • Proficiency with Linux networking and diagnostic tools, including tcpdump, Wireshark, iperf, ss, and ethtool.
  • Experience with version control and code review systems such as Git and Gerrit.
  • Strong analytical, debugging, problem-solving, and documentation skills.
Automation & Tooling (Core Focus)
  • Design and implement test automation for:
    • Network performance benchmarking.
    • Stress, soak, and longevity testing.
    • Configuration validation and rollback scenarios.
  • Develop reusable Python-based test libraries and CLI-driven automation.
  • Automate log collection, test result analysis, and failure triage.
  • Integrate automated test suites with CI/CD systems such as Jenkins or GitLab CI.
  • Experience validating software builds using containerized or virtualized test environments is a plus.
Key Responsibilities
  • Design and execute comprehensive end-to-end test strategies for broadband gateway and extender platforms.
  • Validate core networking behavior across wired and wireless interfaces, including:
    • Layer 2 and Layer 3 forwarding.
    • Routing, Network Address Translation (NAT), and packet flow.
    • IPv4/IPv6 dual-stack and transition scenarios.
  • Perform system-level, integration, regression, and performance testing on embedded Linux devices.
  • Develop and maintain automation frameworks for functional, regression, and performance testing using Python and Shell scripting.
  • Automate the validation of networking behaviors, including throughput, latency, packet loss, failover, and recovery.
  • Analyze network traffic and system behavior using tools such as tcpdump, Wireshark, iperf, and netstat.
  • Debug complex issues across the kernel, middleware, and user space, providing detailed root-cause analysis to development teams.
  • Validate software builds across multiple hardware platforms and vendor SDKs.
  • Integrate automated tests into CI/CD pipelines to support continuous validation.
  • Reproduce and analyze field and customer-reported issues under real-world traffic conditions.
  • Ensure compliance with RDK-B platform standards, performance benchmarks, and release quality criteria.
Nice-to-Have Skills
  • Experience testing Wi-Fi performance and stability across 802.11n/ac/ax standards.
  • Exposure to broadband access technologies such as DOCSIS or fiber gateways.
  • Familiarity with remote management and telemetry systems.
  • Understanding of security and traffic protection mechanisms, including firewalls, authentication, and encryption.
  • Experience working with chipset vendor SDKs, including Broadcom, Qualcomm, or MediaTek.
  • Knowledge of performance tuning and bottleneck identification in embedded systems.
  • Additional scripting and automation experience, including Python utilities, log parsers, and dashboards.
Core Technical Skills
RDK-B, OpenWRT, prplOS, Embedded Linux, Broadband Networking, TCP/IP, IPv4/IPv6, Routing, Bridging, NAT, Network Performance Testing, Python, Shell Scripting, Test Automation, CI/CD, Jenkins, GitLab CI, Wireshark, tcpdump, iperf, Git, Gerrit, System Validation, Regression Testing, and Root-Cause Analysis.
