Job description

Job Title: Senior Platform Engineer Location: Remote + Travel (2 weeks per Quarter) Security Clearance: Top-Secret Eligible We question. We listen. We adapt. Be honest. Be pragmatic. Omni Federal , founded in 2017 and headquartered in Washington, DC, is a highly specialized software solutions provider with a robust presence in key locations across the United States, including Boston, MA, Colorado Springs, CO, San Antonio, TX, and St. Louis, MO. Born out of the Department of Defense's software factory ecosystem, Omni has rapidly distinguished itself by delivering both mission-critical and enterprise solutions that enhance the technological capabilities of the federal government. With a focus on areas such as Command and Control, Cybersecurity, Space, Geospatial, and Modeling & Simulation, Omni leverages cutting-edge commercial technology tailored to government objectives, improving mission performance and delivering transformative outcomes for the Department of Defense (DoD), Intelligence Community (IC), and their end-users. The company's innovative approach is backed by its Omni Labs and SBIR Innovation centers, where they develop advanced platforms and tools in data mesh, secure connectivity, and intelligent automation. Why Omni? • Environment of Autonomy • Innovative Commercial Approach • People over process The Senior Platform Engineer builds and runs the platform the A2D2 development team works from: cloud infrastructure, CI/CD, container builds, model-serving hosts, and the offline install bundles used for accredited on-prem delivery. The role works closely with the Lead Software Engineer and treats the platform as a product for developers: stable, documented, and changed in reviewed, incremental steps so the teams building on it are never surprised. Understanding of the C2 mission is a plus, not a requirement. Required: Technical Skills • 5+ years of overall technical experience • Architected and operated multi-tier AWS GovCloud environments across foundation and services layers using Terraform/OpenTofu module and blueprint patterns with remote state. • Provisioned and hardened ECS Fargate, ECR, IAM, VPC, ALB, Route 53, Secrets Manager/SSM, and CloudWatch in accordance with NIST 800-53. • Built reusable infrastructure modules and pipelines driven from a single source of truth, so service definitions and image publication stay in sync. • Engineered DAG-scheduled pipelines using needs, rules, and change-based execution so that unrelated work does not rebuild or republish. • Administered Docker autoscaler runners with tagged pools, caching strategy, and interruptible job configuration. • Authored multi-stage Docker files with BuildKit inline caching and shared base layers across related services. • Deployed and operated GPU-backed LLM serving stacks (vLLM, Ollama) for production workloads. • Built reproducible install bundles carrying images, charts, IaC, and dependencies with no reliance on an outbound network path at install time . Required: Working with the Team • Treats the platform as a product for developers: stable interfaces, clear onboarding, documented runbooks. • Ships infrastructure and pipeline changes through review in small, reversible increments, with rollback paths. • Partners with the lead engineer on technical direction rather than setting it independently. Nice to Have: • Produced ATO-supporting artifacts including SBOMs, vulnerability triage records, STIG alignment, and NIST 800-53 evidence. • Provisioned GPU-backed inference hosts: driver and CUDA orchestration, device passthrough into containers, and Ansible collections automating the whole stack. • Experience with Platform One, Big Bang, or Iron Bank distribution patterns for accredited on-prem delivery. • Provisioned and maintained GPU-backed inference hosts: driver and CUDA orchestration, device passthrough into containers, and Ansible collections automating the full stack. • Familiarity with C2 or battle management mission context. Our team is always hungry for more – more knowledge, more problem solving, more growth, more innovation, and, ultimately, customer success. This hunger and hustle fuel our determination to excel in everything we do. It’s not just about meeting established goals; it’s about exceeding them. We take immense pride in applying our expertise in cutting-edge technologies and our ability to adapt to emerging trends directly to the users in the field, as our nation’s protectors deserve nothing less.
