You will be part of a team building secure networking solutions across VPN, cryptographic infrastructure, PKI, and SD-WAN integrated 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.

What you will work on:

• Design and build secure networking solutions across VPN (IPSec/IKEv2), PKI, and SD-WAN Platform Infrastructure

• Collaborate with cross-functional engineering teams to design and deliver core security and connectivity features for large-scale deployments

• Use AI-assisted tools such as Codex to improve engineering productivity, 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 brown bags, tech talks, and promoting engineering best practices

Required Skills & Experience

• 5–8 years of experience building production-grade software systems

• 4+ Years of Strong programming skills in C/C++

• Solid understanding of networking fundamentals (TCP/IP, routing, distributed systems)

• 4+ years of hands-on experience designing/enhancing core networking or security or SDWAN features

• Experience designing and delivering scalable and reliable systems

• Experience in embedded Linux software development

• Ability to own features end-to-end from design to deployment

• Strong problem-solving, communication, and collaboration skills

Preferred (Good to Have)

• Experience with IPSec VPN technologies

• Experience in embedded Linux software development workflows, including compilation and integration within Yocto-based or similar Linux platforms.

• Understanding of PKI systems and certificate lifecycle management

• Background in network security

• Exposure to cryptographic systems or secure communication protocols

• Experience using AI-assisted development tools (e.g., Copilot, Codex) to improve engineering productivity

Bonus points for any of the following:

• Exposure to post-quantum cryptography (PQC) or cryptographic agility

• Experience working with networking/security standards (RFCs)

• Embedded Linux system development, Yocto-based build system expertise, and cloud platform integration skills.

• Experience building or using Codex-based agents and AI-assisted tools to improve engineering productivity, automate development workflows, or contribute AI-enabled capabilities to networking and security products

We encourage you to drop us a line even if you don’t have all the points above. That's a lot of different areas of responsibility! We will help you pick them up because we believe that great engineers come from diverse backgrounds.
