Roll: Senior Architect – Firewall /Network Security - C/C++ - 12+
Role Overview
We are looking for a Software Architect to define, design, and guide the development of our next-generation Firewall and Network Security platform. You will play a key role in shaping the technical direction, architecture, and scalability of core product components — including the data plane, control plane, and management layers.
This role demands a deep hands-on understanding of systems software, product development, networking, and performance optimization, combined with the ability to mentor teams and influence design decisions across multiple modules.
Key Responsibilities:
Architecture & Design
- Own the system and component architecture for one or more major subsystems (e.g., Data Plane, Control Plane, Policy Engine, Management/UI).
- Design for scalability, throughput, and reliability across distributed and high-performance systems.
- Evaluate and select technologies, frameworks, and algorithms aligned with performance and maintainability goals.
- Collaborate with other architects and the Director to ensure architectural consistency across the platform.
- Translate product and customer requirements into detailed technical designs and interfaces.
Technical Leadership
- Review design documents, APIs, and code for architectural alignment and quality.
- Guide engineers in implementing robust, modular, and maintainable code.
- Lead performance profiling, debugging, and root-cause analysis of complex system issues.
- Establish design patterns, coding standards, and system documentation practices.
- Serve as a technical advisor to engineering managers and senior engineers during implementation.
Cross-Functional Collaboration
- Work closely with Product Management to evaluate technical feasibility of new features.
- Coordinate with QA, DevOps, and Security teams to ensure testability, observability, and release readiness.
- Support customer escalations when deep technical insight is required.
Required Skills & Experience
- 12+ years of experience in C/C++ systems software development.
- Strong expertise in network security concepts (TCP/IP, IPsec, VPN, routing, NAT, DPI, etc.).
- Proven experience designing multi-threaded, high-performance, and low-latency systems.
- Deep understanding of OS internals, memory management, concurrency, and networking stacks.
- Experience with DPDK, Netfilter or equivalent frameworks.
- Excellent analytical, debugging, and performance-tuning skills.
- Demonstrated ability to write and review detailed design and architecture documents.
- Strong communication skills and ability to collaborate across teams and roles.
