About The Position

LMI is seeking a Junior Platform Engineer to support IronSled, a Platform as a Service designed to host applications in secure federal environments. The role is an initial member of a small, cross-functional team responsible for supporting tenants, maintaining platform reliability, and improving the user experience. The primary responsibility is managing technical issues and service requests submitted by teams using IronSled, owning issues from initial review through resolution, coordinating with senior engineers when deeper expertise is required, and providing tenants with clear and consistent communication.

This is not a traditional help desk position. The engineer will investigate issues across applications, Kubernetes environments, deployment pipelines, identity services, cloud infrastructure, and platform integrations. The role also offers opportunities to automate recurring tasks, improve documentation, and contribute directly to the platform as experience grows. An active TS/SCI security clearance is required.

IronSled sits within LMI’s Chief Technology Office. The small, high-visibility team builds and operates a secure application-hosting platform for federal agencies. Its culture is product-focused and collaborative, with an emphasis on moving quickly, solving problems directly, and prioritizing outcomes. Because users depend on IronSled to operate critical applications, reliability, security, communication, and attention to detail are essential. The engineer will work closely with the Product Manager, Engineering Lead, platform engineers, application developers, and tenant teams, and may help improve support processes, documentation, automation, and technical capabilities as the platform evolves.

Requirements

• Active TS/SCI security clearance.
• 1–3 years of experience in platform engineering, cloud engineering, DevOps, software development, systems administration, or technical support.
• Foundational understanding of Linux, containers, Kubernetes, cloud services, networking, and CI/CD concepts.
• Experience troubleshooting technical issues and working through problems methodically.
• Familiarity with Git, GitLab or GitHub, command-line tools, and infrastructure or application logs.
• Ability to communicate technical information clearly to users with varying levels of experience.
• Strong ownership, organization, and follow-through when managing multiple issues.
• Willingness to learn unfamiliar technologies and seek assistance when appropriate.

Responsibilities

• Manage tenant issues and service requests from initial intake through resolution.
• Troubleshoot problems involving Kubernetes, application deployments, CI/CD pipelines, identity, networking, cloud services, and platform integrations.
• Communicate clearly with tenants about issue status, required information, next steps, and resolution.
• Escalate complex issues to senior engineers while maintaining ownership and coordination.
• Document solutions, recurring problems, and platform procedures in the IronSled knowledge base.
• Identify repetitive support work that can be improved through automation or platform enhancements.
• Assist with tenant onboarding, access requests, environment configuration, and deployment support.
• Contribute to platform maintenance, testing, monitoring, and engineering work as skills develop.
