What are the responsibilities and job description for the DevQA Engineer position at capgemini?
We are seeking a DevQA Engineer with strong expertise in broadband networking and embedded platforms to drive quality across RDK-B based gateway and extender products. This role focuses on end-to-end system validation, automation and performance assurance for complex networking features rather than direct feature development.
You 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 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 paths
Routing and bridging
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, and 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 systems such as Jenkins or GitLab CI.
Experience validating builds using 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).
Key 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
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 using tools like tcpdump, Wireshark, iperf and netstat.
Debug complex issues spanning kernel, middleware and user space and provide 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.
Mandatory skills:
Validation of embedded or networking products, understanding of RDK-B, OpenWRT, or prplOS based systems, embedded Linux, including logs, process analysis, memory usage, and crash debugging
