US_East | Connectivity & Network Engineer_L3

Expedite Talent Solutions, Santa Clara, CA, United States


Overview
Role: DevQA Engineer. Location: Sunnyvale, CA (100% onsite).

Responsibilities

Design and execute end-to-end test strategies for broadband gateway and extender platforms.

Validate core networking behavior across wired and wireless interfaces, including Layer 2/Layer 3 forwarding, routing, NAT, and packet flow.

Validate 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.

Automate validation of networking behaviors such as throughput, latency, packet loss, failover, and recovery.

Analyze network traffic and system behavior with tools like tcpdump, Wireshark, iperf, and netstat.

Debug complex issues spanning kernel, middleware, and user space; provide 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.

Mandatory 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 background in embedded Linux, including logs, process analysis, memory usage, and crash debugging.

In-depth knowledge of TCP/IP networking concepts, including packet flow and forwarding, routing and bridging, and multicast, QoS, and traffic prioritization.

Hands-on experience testing IPv6 technologies and coexistence with IPv4.

Proficiency with Linux networking and diagnostic tools: tcpdump, Wireshark, iperf, ss, ethtool.

Experience with version control and code review systems (Git, Gerrit).

Strong analytical, debugging, and documentation skills.

Automation & Tooling (core focus): design and implement test automation for network performance benchmarking, stress/soak/longevity testing, configuration validation and rollback scenarios; develop reusable Python-based test libraries and CLI-driven automation; automate log collection, result analysis, and failure triage; integrate test suites with CI/CD (Jenkins or GitLab CI).

Experience validating builds in containerized or virtualized test environments is a plus.

Nice to Have

Experience testing Wi-Fi performance and stability (802.11n/ac/ax).

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 (firewalls, authentication, encryption).

Experience working with chipset vendor SDKs (Broadcom, Qualcomm, MediaTek).

Knowledge of performance tuning and bottleneck identification in embedded systems.

Scripting or automation experience beyond testing (Python utilities, log parsers, dashboards).
