Software Engineer - Software Defined Networking (SDN)

Team: IT

Location: US

Commitment: Full-time

Workplace Type: remote

Accountabilities:

• Own the technical assessment of an SDN codebase, including architecture, build processes, dependencies, runtime components, test coverage, security posture, and upstream open-source relationships.
• Design and implement secure, maintainable changes that remediate vulnerabilities, improve resilience, and maintain traceability between upstream software, government-owned code, configurations, and local patches.
• Develop reliable unit, integration, end-to-end, regression, and failure-mode tests for hardening and modernization initiatives.
• Implement AI-enabled tooling to support the ongoing hardening, maintenance, analysis, and development of the SDN application.
• Diagnose complex issues across application, Linux, and network boundaries, including traffic flows, routing, segmentation, identity, failover, telemetry, and performance.
• Partner with platform engineering teams on container readiness, packaging, CI/CD, deployment workflows, and automated security scanning while owning code-level triage and remediation.
• Support laboratory validation, demonstrations, release acceptance, and the conversion of operational findings into durable fixes and regression tests.
• Contribute to architecture and code reviews and communicate technical tradeoffs clearly to engineering and government stakeholders.
• Produce clear technical documentation, assessments, and runbooks to support reliable operation and long-term sustainment.
• Mentor other engineers and contribute to evolving engineering practices as mission requirements and technical needs change.

Requirements:

• 5+ years of software engineering experience with demonstrated ownership of production or legacy codebases.
• Strong proficiency in C++, Python, and Bash scripting.
• Strong Linux fundamentals, including services, processes, permissions, logging, package management, and command-line troubleshooting.
• Strong networking fundamentals, including TCP/IP, routing, DNS, TLS, segmentation, network interfaces, policy enforcement, and traffic analysis.
• Experience with secure software development, dependency management, vulnerability triage, patching, code review, and remediation.
• Strong testing discipline across unit, integration, end-to-end, and regression testing.
• Working knowledge of containers, version control, build automation, CI/CD, registries, observability, and modern software release practices.
• Strong problem-solving, communication, and technical documentation skills, including experience producing design documents, technical assessments, and runbooks.
• U.S. citizenship and an active U.S. Government Secret security clearance or higher are required.
• Experience developing or sustaining SDN, network orchestration, routing, virtual network functions, network appliances, or other network-control software is preferred.
• Experience containerizing VM-based or monolithic software and maintaining upstream open-source integrations, forks, or patches is a plus.
• Strong familiarity with agentic AI-assisted engineering tools and workflows for codebase analysis, remediation, resilience testing, and software development is preferred.
• Familiarity with Kubernetes, Helm, GitOps, OCI artifacts, and modern software delivery practices is beneficial.
• Experience with SAST, DAST, software composition analysis, SBOMs, container scanning, STIGs, and automated security checks is preferred.
• Experience with performance, resilience, chaos engineering, and observability for distributed or networked systems is a plus.
• Experience modernizing or migrating applications from virtual machine-based environments to containerized deployments is beneficial.
