Core Protocol & Systems Engineering - Senior Architect

Job Description

• This position is posted by Jobgether on behalf of a partner company. We are currently looking for a Core Protocol & Systems Engineering - Senior Architect in India. This is a senior-level architecture role focused on designing and evolving next-generation data-plane and control-plane systems for high-performance networking environments. You will define end-to-end system architecture spanning protocol stacks, Linux kernel networking, and distributed system interactions. The role requires deep expertise in low-level systems design, performance engineering, and scalable network infrastructure. You will influence critical design decisions across TCP/IP enhancements, kernel/user space boundaries, and packet processing pipelines. You will collaborate closely with engineering leaders, product teams, and cross-functional stakeholders to shape long-term platform strategy. This position also involves mentoring senior engineers and technical leads while driving architectural consistency across teams. It is a highly impactful role for someone passionate about building robust, scalable, and performance-optimized systems at scale.
• Accountabilities: Define and own the architecture of high-performance networking systems, including protocol stacks, data-plane components, and distributed system behaviors. Lead system-level design decisions involving TCP/IP optimizations, Linux kernel networking stack behavior, and user-space versus kernel-space trade-offs. Architect scalable solutions for threading models, memory management, interrupt handling, and performance-critical execution paths. Drive system performance engineering efforts, including profiling, workload analysis, bottleneck identification, and scalability improvements. Collaborate with leadership and cross-functional teams to influence technical roadmap direction and platform evolution. Mentor senior engineers and technical leads while promoting architectural best practices across engineering teams. Produce detailed architecture documentation, technical strategy papers, and in-depth system analysis reports. Requirements: 10+ years of experience in systems engineering, networking, or kernel-level development with proven architectural ownership of large-scale platforms. Strong academic background with a degree in Computer Science, Computer Engineering, or a related field. Mastery of C and C++ with deep experience in systems programming and low-level architecture design. Strong understanding of TCP/IP protocols, routing and switching mechanisms, and high-performance packet processing systems. Expertise in multithreaded system design, CPU scheduling, memory models, and interrupt-driven architectures. Hands-on experience with distributed systems, cloud networking, and virtualization or container-based environments. Strong analytical thinking, architectural vision, and ability to influence senior technical and executive stakeholders. Excellent communication skills with the ability to articulate complex technical concepts clearly. Preferred experience in constrained or managed WAN environments such as satellite or telecom systems. Familiarity with high-latency or variable-bandwidth networks and Performance Enhancing Proxies, including TCP acceleration or optimization techniques. Benefits: Competitive compensation aligned with senior-level industry standards Flexible work arrangements depending on role and project requirements Comprehensive health and wellness coverage Opportunities for continuous learning and technical development Exposure to large-scale, high-impact system architecture challenges Collaborative and innovation-driven engineering environment Career growth opportunities in advanced systems and networking domains
