This is an exciting opportunity to use your experience helping multiple DoD customers develop "bleeding edge" technology protecting our warfighters in the field. Your role will directly support our diverse portfolio of programs through a combination of Network Infrastructure Design & Deployment; Automation & Scripting and Troubleshooting & Analysis. You may be requested to provide software support to help with integration of the new technologies into existing networked systems., You will design, build, and automate large-scale data networks, focusing on scalability, reliability, and performance. You will be asked to design & automate IT & networks, integrate infrastructure equipment for deployments, manage configurations, and perform deep troubleshooting, often bridging network operations with software development teams. Key responsibilities include ensuring that disparate hardware, software, and networking components function cohesively as a unified, efficient system. Day-to-day life will involve: * Architecture & Design: Planning and mapping out how different software systems, APIs, and hardware devices will communicate with one another. * Testing & Validation: Writing test scripts, running diagnostics, and ensuring systems are secure, compliant, and scalable. * Automation & Scripting: Develop tools, scripts, and reusable libraries to handle repetitive manual tasks. * Troubleshooting & Analysis: Debug and solve complex network issues, performing deep dives into hardware and protocols. * Documentation & Collaboration: Partner with system designers and developers to create engineering design documents, policies, and best practices. * CI/CD Pipelines: Integrate network changes into GitHub Actions or GitLab for pre-deployment testing, rollback capabilities, and strict version control. ## Related Videos - [Docker network without Docker](https://www.wearedevelopers.com/videos/1418-docker-network-without-docker) - [Improving quality with Agentic AI with Rovo Dev and Xray](https://www.wearedevelopers.com/videos/2005-improving-quality-with-agentic-ai-with-rovo-dev-and-xray) - [Security Pitfalls for Software Engineers](https://www.wearedevelopers.com/videos/726-security-pitfalls-for-software-engineers) - [Docker exec without Docker](https://www.wearedevelopers.com/videos/1094-docker-exec-without-docker) - [Collaboration Quantified: Lessons from Open Source Developer Networks](https://www.wearedevelopers.com/videos/1422-collaboration-quantified-lessons-from-open-source-developer-networks) - [Enabling automated 1-click customer deployments with built-in quality and security](https://www.wearedevelopers.com/videos/83-enabling-automated-1-click-customer-deployments-with-built-in-quality-and-security) ## Related Articles - [How We Built a Worry-Free System That Runs for 10+ Years – And What We’d Do Again](https://www.wearedevelopers.com/magazine/751-how-we-built-a-worry-free-system-that-runs-for-10-years-and-what-we-d-do-again) - [Fully Remote Software Engineer Jobs](https://www.wearedevelopers.com/magazine/447-fully-remote-software-engineer-jobs) - [Is Software Engineering Over-Saturated?](https://www.wearedevelopers.com/magazine/418-is-software-engineering-over-saturated) - [Highest Paying Tech Companies for Developers](https://www.wearedevelopers.com/magazine/220-highest-paying-tech-companies-for-developers) - [Where to Find Entry-Level Software Engineering Jobs](https://www.wearedevelopers.com/magazine/397-where-to-find-entry-level-software-engineering-jobs) - [Why Upskilling And Reskilling is Important For Developers](https://www.wearedevelopers.com/magazine/428-why-upskilling-and-reskilling-is-important-for-developers)
