Job details:
Key Responsibilities:
- Develop and maintain the high-performance packet processing applications using Data Plane Development Kit (DPDK) for networking and telecom products.
- Perform low level debugging, profiling and performance analysis of DPDK Poll Mode Drivers (PMD), Libraries, Applications using the tools such as Linux perf, objdump, BPF Tools and GDB.
- Analyze the customer's reported issues, reproduce them in controlled environments, and provide the root cause analysis using or developing the DPDK based applications and traffic patterns.
- Conduct detailed code reviews, identify performance bottlenecks, and implement optimizations to improve throughput, latency, and CPU efficiency.
- Evaluate upstream DPDK patches, do platform level impact analysis, create test scenarios, and execute the functional and performance regression test suites to ensure zero regressions and sustained performance benchmarks.
- Optimize critical data paths using SIMD/Vector instructions (SSE/AVX/NEON) and leverage CPU micro architecture features for parallelism and cache efficiency.
- Work closely with NIC Hardware (Intel, Mellanox and Broadcom), Accelerators, PCIe subsystems, and driver layers to ensure the optimal packet I/O performance.
- Provide detailed documentation and training to QA and automation teams on evaluation of DPDK based applications and POCs.
- Port and validate the DPDK based applications across heterogenous architectures (x86 and ARM), ensuring the performance evenness and platform stability.
Required Skills
- Strong proficiency in C programming and data structures with a focus on system level and performance critical application development
- In depth understanding of DPDK Architecture including EAL, Mempool, Mbuf, rings, PMDs, multicore packet processing models.
- Solid knowledge of computer architecture (x86) including cache hierarchy, NUMA, Instruction level parallelism.
- Hands on experience with Linux system programming, including process and thread management, memory access techniques, and synchronizations primitives.
- Strong debugging and profiling skills on Linux systems using perf, GDB, BPF tools, and flame graphs.
- Good understanding of Linux kernel internals, networking stack, Kernal and user space interactions.
- Experience with PCIe, device drivers, High Speed NICs, Accelerators.
- Familiarity with Linux system configuration and performance tuning (
- sysfs, GRUB parameters, CPU Isolation, Hugepages)
- Strong fundamentals in networking protocols: IPv4, IPv6, TCP, UDP, VLAN, GTP, NAT, ACLs, Routing and Switching.
Good to Have:
- Knowledge of OpenVSwitch (OVS), SR-IOV, RSS, HW Offloads, NUMA, and Cache-aware application design.
- Exposure to DPDK baseband, event dev, crypto and graph libraries.
- Experience in telecom/data plane use cases – 5G UPF, vRAN, DPI, Load balancing and Packet Gateways.
- Exposure to Kubernetes, Dockers and K8S Operators.
- Familiarity with CI/CD pipelines, Unit Testing.
