Explore high-impact Senior Software Development Engineer jobs specializing in Routing and Secure Access Service Edge (SASE). This senior-level role sits at the critical intersection of network infrastructure, cloud security, and software engineering, focusing on designing, building, and maintaining the core platforms that enable secure, performant, and scalable global connectivity. Professionals in these positions are instrumental in creating the intelligent routing and integrated security frameworks that define modern, cloud-native enterprise networks. A Senior SDE in Routing/SASE typically shoulders end-to-end ownership of complex systems. Common responsibilities include architecting and developing high-throughput, low-latency routing algorithms and protocols, as well as integrating comprehensive security stacks—including Firewall as a Service (FWaaS), Cloud Access Security Broker (CASB), Zero Trust Network Access (ZTNA), and Secure Web Gateway (SWG)—into a unified SASE platform. They design resilient microservices and APIs that power these global services, ensuring seamless user experience and robust policy enforcement regardless of user or application location. A key part of the role involves close collaboration with cross-functional teams, including network architects, security specialists, and product managers, to translate business requirements into technical specifications and executable roadmaps. Furthermore, these engineers are expected to lead initiatives in performance optimization, scalability improvements, and the automation of deployment and operational processes, often mentoring junior engineers and setting technical best practices within their teams. To excel in these senior jobs, candidates generally possess a strong foundation in computer science principles, coupled with deep, hands-on expertise in several key areas. Typical technical requirements include proficiency in programming languages like Go, Python, Java, or C++, and extensive experience with cloud platforms (AWS, Azure, GCP) and container orchestration (Kubernetes). A firm grasp of networking fundamentals—TCP/IP, BGP, SD-WAN, VPN technologies—and modern security concepts is paramount. Experience with infrastructure as code (Terraform, Ansible), CI/CD pipelines, and monitoring/observability tools is also highly valued. Beyond technical acumen, successful professionals demonstrate strong problem-solving skills, the ability to design for scale and resilience, and excellent communication skills to articulate complex technical concepts. A bachelor’s or master’s degree in Computer Science or a related field, along with 5-8 years of progressive software development experience, particularly in networking or security domains, is a common expectation for these advanced roles. If you are passionate about building the foundational platforms that secure and connect the digital world, exploring Senior Software Development Engineer - Routing/SASE jobs could be the next pivotal step in your career.
