You will work on complex, high-performance platform components that operate at scale and enable mission-critical services.

Key Responsibilities:

• Design, develop, and optimize platform components with a focus on Linux internals, networking stacks, and high-throughput data plane applications (DPDK).
• Collaborate closely with System Architect, Network Engineers, Security, and Product teams to define architectural requirements and deliver robust solutions.
• Working across hybrid environments leveraging public cloud infrastructure (AWS, GCP, Azure) and on-premises systems.
• Analyze system bottlenecks and drive performance improvements, virtualization, and application layers.

• Bachelor’s or Master’s degree in Computer Science, Engineering, or a related technical field.
• Systems Programming: Proficient in C/C++, Bash, and Python for low-level development, automation, userspace system-level applications, and performance tuning.
• Linux Internals: Solid understanding of kernel subsystems including memory management, process scheduling, file systems, userspace interactions, and device drivers.
• Multithreading & Performance Optimization: Strong grasp of concurrency, synchronization, and real-time optimization in system-level applications.
• Distributed Systems Engineering: Proven ability to design, build, and scale resilient distributed systems and platform services.
• Networking & Data Plane Development: Experience with DPDK, NIC offloading, and high-throughput, low-latency packet processing ( Big Advantage)
• Strong analytical and Problem Solving: Analytical mindset with deep debugging skills and a focus on performance-driven, reliable solutions.

Nice to have:

• Practical knowledge of hypervisors and virtualization technologies (KVM, VMware).
• Experience with container orchestration platforms (Kubernetes) and service mesh architectures.
• Familiarity with operational best practices for large-scale infrastructure.
• Experience designing and deploying systems on public cloud platforms (GCP, AWS, Azure).

Soft Skills:

• Strong communication skills with the ability to document designs and present technical solutions.
• Highly collaborative with a proactive, ownership-driven mindset.
