As a Senior Software Developer, you will design and develop core software modules that power secure, scalable, and high-performance firewall and network security solutions, working closely with architects and cross-functional teams.

Key Responsibilities:

- Design, develop, and optimize firewall software modules for next-generation cybersecurity solutions, including NGFW, SASE, ZTNA, SWG, VPN, and SD-WAN.

- Contribute to design decisions and to the technical direction of the firewall and cybersecurity platform.

- Ensure the scalability, performance, and security of software components through thoughtful design and rigorous testing.

- Mentor junior developers and promote best practices in coding, design, and the software development lifecycle.

- Conduct code reviews, contribute to technical documentation, and support continuous integration and deployment processes.

- Stay current with industry trends, emerging technologies, and evolving security threats to ensure the product remains competitive and secure.

- Troubleshoot complex technical issues and provide timely resolutions in both development and production environments.

Required Qualifications:

- Bachelor’s degree in computer science, Engineering, or a related technical field.

- 5–8 years of hands-on networking, cloud, and security software development experience, with a strong background in systems programming, networking, or security-related domains.

- 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.
