Junior Networking Jobs in Oregon (NOW HIRING)

LMI is seeking a Junior Platform Engineer to support IronSled, a Platform as a Service designed to host applications in secure federal environments. You will be an initial member of a small, cross-functional team responsible for supporting tenants, maintaining platform reliability, and improving the overall user experience.

Your primary responsibility will be managing technical issues and service requests submitted by teams using IronSled. You will own issues from initial review through resolution, coordinate with senior engineers when deeper expertise is required, and ensure tenants receive clear and consistent communication throughout the process.

This is not a traditional help desk position. You will investigate issues across applications, Kubernetes environments, deployment pipelines, identity services, cloud infrastructure, and platform integrations. You will also have opportunities to automate recurring tasks, improve documentation, and contribute directly to the platform as your experience grows.

This position requires the ability to obtain a security clearance. U.S. citizenship is required. 

IronSled sits within LMI's Chief Technology Office. We are a small, high-visibility team building and operating a secure application-hosting platform for federal agencies. Our culture is more product-focused and collaborative than a traditional government contracting environment. We move quickly, solve problems directly, and prioritize outcomes over unnecessary process.

At the same time, our users depend on IronSled to operate critical applications, making reliability, security, communication, and attention to detail essential.

You will work closely with the Product Manager, Engineering Lead, platform engineers, application developers, and tenant teams. Because IronSled is continuing to evolve, you will have opportunities to help improve its support processes, documentation, automation, and technical capabilities.

LMI is a new breed of digital solutions provider dedicated to accelerating government impact through innovation and speed. By investing in technology and prototypes ahead of need, LMI delivers commercial-grade platforms and mission-ready artificial intelligence capabilities to federal agencies at commercial speed.

Headquartered in Tysons, Virginia, LMI supports the defense, space, healthcare, and energy sectors, helping agencies navigate complexity, modernize critical capabilities, and strengthen mission outcomes.
