Program Overview

At KBR, our National Security Solutions team delivers advanced engineering and mission-critical technology to customers across the intelligence and national security communities. In support of our Novastar program, we are expanding our software engineering capability and seeking high-caliber talent to join a growing, technically elite team.

We are hiring:

• Senior Software Engineers
• Front-End (UI) Engineers
• Software Developers

Why KBR?

Mission-Focused Innovation

Work at the leading edge of engineering, mission IT, cybersecurity, and advanced defense systems.

Collaborative Engineering Culture

Join a high-performance environment that values technical rigor, knowledge sharing, and continuous innovation.

National Impact

Contribute to the architecture and optimization of systems that directly support national security and next-generation defense capabilities.

Position Overview

KBR is seeking experienced Senior Software Engineers and Front-End Engineers to support mission-critical systems in the Dayton, Ohio area. The ideal candidate is a front-end (UI) expert with active DoD clearance and deep experience building secure, scalable platforms in highly controlled environments.

Core Responsibilities

Platform & Kubernetes Engineering

• Architect and operate multi-cluster Kubernetes environments (control, data, CI/CD, and observability planes) with strong isolation and zero-trust security defaults.
• Lead implementation of service mesh technologies (e.g., Istio) to enable mTLS, traffic shaping, and fine-grained authorization policies.
• Manage ingress configurations (Gateways/VirtualServices) and east-west traffic policies.
• Develop and maintain Kubernetes CRDs, controllers, and operators to reconcile developer intent into runtime infrastructure.
• Implement network policy enforcement (eBPF/Cilium), secrets management, RBAC/ABAC, and policy-driven automation.
• Establish and maintain observability stacks (metrics, logs, traces) and SLO-driven reliability standards.
• Support high availability (HA), backup/restore strategies, and disaster recovery (DR) planning.
• Enable secure air-gapped deployments and software supply chain integrity (container images, SBOMs, provenance).

Front-End & UX Engineering

• Build a "single pane of glass" developer and consumer interface to streamline modeling, orchestration, monitoring, and analytics workflows.
• Design and implement modular front-end applications using React/TypeScript (or equivalent frameworks).
• Develop reusable components and UX patterns tailored to operational planners and mission users.
• Integrate with REST, gRPC, and GraphQL APIs supporting model catalogs, scenario design, job orchestration, and metadata access.
• Implement real-time visualization of timing, synchronization, and entity interactions via WebSockets or Server-Sent Events.
• Build secure UI flows incorporating OIDC/OAuth2 authentication, role-based access control, and audit logging.
• Translate complex simulation constructs (timing models, state-of-play logic, user-driven inputs) into intuitive, mission-ready user experiences.
• Collaborate closely with API, platform, and HPC engineering teams to continuously refine workflows aligned to mission validation, verification, and accreditation (VV&A) requirements.

Qualifications

• Active DoD security clearance required.
• Advanced experience with Kubernetes in multi-cluster environments.
• Strong background in service mesh architecture (Istio or equivalent).
• Proficiency in modern front-end frameworks (React/TypeScript preferred).
• Experience building secure systems in connected and air-gapped environments.
• Deep understanding of zero-trust architectures and policy-driven security.
• Familiarity with high-performance computing (HPC) and simulation-driven systems preferred.

If you are passionate about building secure, scalable, and mission-critical platforms in support of national security objectives, we encourage you to apply. A member of our recruiting team will follow up directly.
