About the job

Overview

We are looking for a Platform Engineer to design, build, and operate the foundational technology platforms that enable secure, scalable, and efficient software delivery across the organization. This role focuses on building internal platforms and infrastructure capabilities that allow engineering teams to deliver applications quickly while maintaining strong standards for security, reliability, and operational performance.

You will work across DevSecOps platforms, cloud and hybrid infrastructure, networking, and enterprise technical standards, helping create reusable platform services that simplify infrastructure complexity and enable self-service development environments.

This role sits at the intersection of enterprise architecture, infrastructure engineering, and software delivery, ensuring that systems are standardized, secure, and designed to support mission-critical workloads.

LMI is a new breed of digital solutions provider dedicated to accelerating government impact with innovation and speed. Investing in technology and prototypes ahead of need, LMI brings commercial-grade platforms and mission-ready AI to federal agencies at commercial speed.

Leveraging our mission-ready technology and solutions, proven expertise in federal deployment, and strategic relationships, we enhance outcomes for the government, efficiently and effectively. With a focus on agility and collaboration, LMI serves the defense, space, healthcare, and energy sectors—helping agencies navigate complexity and outpace change. Headquartered in Tysons, Virginia, LMI is committed to delivering impactful results that strengthen missions and drive lasting value.

Responsibilities

Design and build internal platform capabilities that support application development, deployment, and operations

Establish and implement enterprise technical standards and architecture patterns for infrastructure, platforms, and development environments

Develop and maintain DevSecOps platforms and CI/CD pipelines that support secure and automated software delivery

Design and operate cloud and hybrid infrastructure environments across AWS, Azure, on-premises, or edge environments

Engineer and manage compute, storage, and virtualization platforms supporting scalable workloads

Design and maintain secure network architectures and connectivity, including segmentation, zero trust approaches, and hybrid networking

Build and operate infrastructure as code (IaC) capabilities to standardize environment provisioning and configuration

Implement security boundaries, platform hardening, and baseline configurations aligned with enterprise security requirements

Support endpoint and collaboration platforms that enable secure productivity and engineering workflows

Manage infrastructure lifecycle operations including provisioning, upgrades, patching, and capacity planning

Collaborate with security, architecture, and product engineering teams to ensure platforms support secure, compliant, and reliable application delivery

Improve platform reliability through monitoring, automation, and operational tooling

Qualifications

Strong experience designing and operating modern infrastructure and platform environments

Experience building and maintaining DevOps or DevSecOps platforms and CI/CD pipelines

Proficiency with cloud platforms (AWS, Azure, or GCP) and hybrid infrastructure architectures

Experience with infrastructure as code using tools such as Terraform, CloudFormation, Pulumi, or similar frameworks

Experience working with containerization and orchestration platforms such as Docker and Kubernetes

Strong understanding of networking fundamentals, including routing, segmentation, and secure connectivity

Experience managing compute, storage, virtualization, and infrastructure services

Familiarity with automation, configuration management, and platform observability tools

Strong engineering fundamentals including version control, automation, and operational reliability

Preferred Qualifications

Experience designing internal developer platforms or platform engineering capabilities

Familiarity with enterprise architecture frameworks and technical standardization

Experience implementing DevSecOps practices including automated security scanning and policy enforcement

Knowledge of zero trust networking, identity-aware infrastructure, and secure platform architectures

Experience supporting regulated or security-sensitive environments

Experience with infrastructure monitoring, logging, and observability platforms

Familiarity with endpoint management and collaboration platforms

Experience working in cloud-native and hybrid enterprise environments

What Success Looks Like

Engineering teams can provision environments and deploy applications quickly using standardized platforms

Infrastructure is automated, reproducible, and managed through code

Platforms provide secure, reliable, and scalable foundations for mission applications

Enterprise technical standards are consistently implemented across environments

Infrastructure operations are highly automated and operationally efficient

Platform capabilities improve developer productivity and delivery velocity

Why This Role Matters

Modern organizations depend on platforms that enable engineering teams to move quickly without sacrificing security or reliability. The Platform Engineer builds and operates these foundational

capabilities—turning complex infrastructure into reusable, automated platform services that support secure and scalable software delivery.

By standardizing infrastructure, automating operations, and enabling self-service environments, this role helps ensure that development teams can focus on building mission capability rather than managing infrastructure complexity.
