• Experience working on enterprise-grade cybersecurity products or network infrastructure solutions.
• Strong expertise in firewall and network technologies such as NGFW, stateful and deep packet inspection (DPI), IDS/IPS, NAT, VPNs, SWG, ZTNA, SD-WAN, and SASE.
• Hands-on experience with Linux networking and packet-processing stacks such as netfilter / iptables / nftables, eBPF/XDP, or DPDK.
• Proven experience designing and building scalable, high-performance software solutions in complex, distributed environments.
• Proficiency in cloud-native architectures, microservices, and containerization technologies such as Docker and Kubernetes.
• Proficiency in programming languages such as C, C++, Go, Rust, or Python
• Solid understanding of cybersecurity principles, networking protocols, and secure software development practices.
• Strong problem-solving skills and the ability to contribute to technical discussions and make sound design decisions.
• Excellent communication and collaboration skills, with the ability to work effectively across teams and mentor junior developers.

Preferred Qualifications (optional):

• Experience with CI/CD pipelines, automation tools, and modern DevOps practices, including automated testing for networking and security software.
