You are customer-obsessed, building deep empathy for both internal and external users while anchoring your decisions in solving real-world problems.
You are driven by innovation, bringing deep curiosity to complex technical challenges and constantly seeking better, more secure, and scalable solutions.
You think at scale, connecting your daily work to the larger mission to build solutions that support a high-growth, global organization.
You lead with integrity by holding yourself and others to high standards of accountability and building trust through consistent, transparent action.

What We’re Looking for (Minimum Qualifications)

12 + years of experience of total experience and proven experience in designing and implementing networking security software and public clouds infrastructure
Deep understanding of Proxies, HTTP/2, QUIC, TCP/IP, TLS/DTLS and SSL proxies
Proficient in C language
Demonstrated success in designing, optimizing, and troubleshooting high-throughput, low-latency network security products
Bachelor’s degree in Computer Science, Information Technology, or related field

What Will Make You Stand Out (Preferred Qualifications)

Proven ability to leverage AI technologies and workflows to drive measurable operational efficiency
Mastery of TCP/IP, DNS, Http(s), VPN technologies (IPSec, SSL VPN), NAT, and load balancing
Knowledge of BSD/Linux operating systems, virtualization technologies, and DPDK or similar kernel bypass techniques
