Meet the Team

We, Security, Solutions and SD-WAN Platform Infra, are a team focused on building next-generation secure connectivity solutions across VPN, cryptography, PKI, and SD-WAN. Across on-prem, cloud, and SSE/SIG environments, we deliver secure, scalable systems and apply AI intelligence to improve security posture, automate certificate lifecycle management, optimize performance, and enable predictive monitoring at scale. Our work spans SD-WAN Platform Infrastructure, crypto infrastructure, PKI systems, VPN technologies, SD-WAN secure fabric, and post-quantum security, powering millions of secure connections globally.

We are looking for a Software Engineer/Sr. Software Engineer to join team. You will belong to a team building secure networking solutions in a high-impact, fast-paced environment. Your work will help shape scalable, secure systems that enable site-to-site and remote access VPNs, certificate-driven trust models, cloud connectivity, and AI-enhanced secure SD-WAN architectures including initiatives in post-quantum security.

Your Impact

• Design and build secure networking solutions across VPN (IPSec/IKEv2), PKI, and SD-WAN Platform Infrastructure
• Collaborate with multi-functional engineering teams to build and deliver core security and connectivity features for large-scale deployments
• Use AI-assisted tools such as Codex to improve engineering efficiency, automation, debugging, and software quality
• Contribute to high-impact projects that improve scalability, resiliency, security posture, and customer experience
• Share and broaden your knowledge by giving tech talks, and promoting engineering standard processes

Minimum Qualifications

• 8+ years of deep technical experience across networking and security domains, large-scale, production-grade systems
• Strong programming expertise in C/C++
• Deep understanding of networking concepts (TCP/IP, routing, distributed systems)
• Validated experience in system design and architecture for scalable, reliable systems
• Track record of leading critical projects end-to-end
• Experience in embedded Linux software development
• Ability to influence technical direction across teams
• Good communication skills with the ability to simplify complex technical concepts

Preferred Qualifications

• Experience with IPSec VPN technologies
• Embedded Linux system development, Yocto-based build system expertise, and cloud platform integration skills.
• Understanding of PKI systems and certificate lifecycle management
• Background in network security, SD-WAN, or secure connectivity
• Exposure to cryptographic systems and protocols
• Experience demonstrating AI-assisted development tools to improve team productivity
• Exposure to post-quantum cryptography (PQC) or cryptographic agility
• Experience chipping in to networking/security standards (RFCs)
