Senior Platform Developer

This is a U.S. based position. All of the programs we support require U.S. citizenship to be eligible for employment. All work must be conducted within the continental U.S.

N3bula Systems is at the forefront of infrastructure automation and secure platform engineering, delivering open, resilient solutions for national defense and intelligence missions. In 2025, N3bula Systems joined forces with Raft-a mission‑obsessed, non‑traditional prime focused on distributed data systems, platforms at scale, and agentic AI. Together, they’re accelerating mission‑critical AI innovation and transforming how the U.S. military connects sensors, shooters, and decision‑makers across domains to enable a unified joint force.

As part of the Raft, N3bula Systems brings deep expertise in systems architecture, cloud automation, and cybersecurity—now supercharged by Raft’s edge‑native AI, autonomous data fusion, and scalable software platforms. Their combined capabilities deliver real‑time, warfighter‑ready solutions that solve the most complex national security challenges at speed, at scale, and without compromise.

We are hiring a Platform Developer to build secure, automated infrastructure components that power mission‑critical environments. You’ll work as part of a small, highly skilled development team delivering Puppet modules, Helm charts, CI/CD pipelines, and automation scripts for integration by downstream engineering teams. This position is primarily remote, but you must be based in San Diego, CA and available to visit customer facilities as needed for meetings, coordination, or support during integration and deployment activities.

This is a development‑focused role—you will not be maintaining infrastructure, but writing the code that builds and configures it.

• Collaborate with fellow developers to design, develop, and maintain Puppet modules that enforce secure system configurations and ensure compliance with organizational standards.
• Create and maintain Helm charts to support Kubernetes‑based deployments, ensuring scalability, reliability, and ease of management.
• Build and optimize CI/CD pipelines using Git Lab, promoting efficient, automated, and secure software delivery.
• Develop automation scripts using Bash and Python to streamline infrastructure management and operational workflows.
• Partner closely with platform and integration engineers to ensure a seamless handoff, integration, and implementation of developed codebases.
• Contribute to the creation and enhancement of reusable, modular infrastructure code libraries that improve development efficiency and consistency across projects.
• Ensure all developed code aligns with Department of Defense (DoD) security requirements and adheres to STIG compliance standards.
• Support customer success initiatives by occasionally participating in on‑site meetings and integration efforts to facilitate smooth deployments and address technical challenges.

• Bachelor’s in related field (preferred)
• 15+ years of experience in infrastructure/platform development
• Hands‑on expertise in:
  • Kubernetes (RKE2 preferred)
  • Helm chart development
  • CI/CD pipeline creation in Git Lab
  • Puppet module and Hiera development
  • Bash and Python scripting
  • Ansible (for supplemental configuration)
  • Strong understanding of RHEL Linux environments
  • Ability to write clean, modular code intended for handoff

• Master’s Degree in related field (preferred)
• Experience with container tools and registries (Harbor, Trivy, Skopeo)
• Familiarity with LDAP, Keycloak, or centralized auth systems
• Previous experience supporting DoD/IC environments
• Experience developing for disconnected or air‑gapped systems
• Contributions to open‑source infrastructure automation projects

• Ability to obtain and maintain a Top Secret / SCI

• Remote with a preference for candidates based in San Diego, CA, Arlington, VA, Colorado Springs, or Tampa, FL
• May require up to 15% travel

• $165,000 - $200,000
• The determination of compensation is predicated upon a candidate's comprehensive experience, demonstrated skill, and proven abilities
