The Mission

Are you ready to engineer the technological backbone of next-generation defense systems?

In an era where technological superiority defines global security, our mission is to build the ultimate, highly automated infrastructure that powers advanced AI and machine learning capabilities. We are looking for a visionary Platform Engineer to design, automate, and scale the resilient, cloud-native environments that our AI, Data, and Security teams rely on.

If you are passionate about "zero-touch" infrastructure, hyper-automation, and enabling mission-critical AI in high-stakes environments, we want you on our front line.

Responsibilities

As a core driver of our infrastructure evolution, you will transform how defense technologies are deployed, managed, and scaled:

• Architect Cloud-Native Ecosystems: Build, operate, and continuously evolve ultra-resilient, cloud-native platforms utilizing Kubernetes, Docker, and advanced container orchestration.
• Drive Hyper-Automation: Eliminate manual toil by engineering heavily automated infrastructure using robust Infrastructure as Code (IaC) tools like Terraform and Ansible.
• Master Hybrid Environments: Seamlessly operate and bridge complex hybrid infrastructures across On-Premises, Private/Public Clouds, Virtualized environments, and Bare Metal.
• Enable AI Delivery: Implement and operate cutting-edge CI/CD pipelines optimized for the rapid, secure deployment of mission-critical software, APIs, and AI/ML models.
• Tactical Observability: Ensure absolute availability and peak performance through comprehensive monitoring, logging, and state-of-the-art observability platforms.
• Enforce Zero-Trust Security: Manage robust identity, secret, and access control frameworks (e.g., Vault, OIDC) essential for classified and highly sensitive operations.
• Empower the Data Backbone: Support and optimize advanced storage and data services (S3-compatible storage, Block/File Storage) that fuel our AI engines.
• Design Cyber Resilience: Co-architect uncompromising security concepts, leading initiatives in network segmentation, military-grade encryption, and strict regulatory compliance.
• Cross-Functional Synergy: Collaborate directly with our elite AI, Data, API, and Security task forces to seamlessly integrate, stabilize, and scale AI-enabled services.

To succeed in this high-impact role, you bring a blend of deep technical expertise and a "security-first" mindset:

• Platform Mastery: Multi-year, hands-on experience designing and operating container technologies and orchestration systems (Kubernetes, Docker) at enterprise scale.
• Infrastructure Expertise: Proven track record with Cloud Infrastructures (AWS, GCP, OpenStack) as well as modern Virtualization Stacks (e.g., KVM, VMware).
• IaC Native: Deep foundational knowledge and practical application of IaC ecosystems (Terraform, Helm, Kustomize, etc.).
• Pipeline Proficiency: Extensive experience architecting automated workflows with modern CI/CD technologies (GitLab CI, ArgoCD, Jenkins, or similar).
• SecOps Mindset: Strong understanding of operational security, encompassing monitoring, logging, network defense, and IAM.
• Scripting for Automation: Fluency in scripting languages (e.g., Python, Bash) to drive our mandate for total automation.
• AI Affinity: A solid baseline understanding of data pipelines, Machine Learning workflows, and API infrastructure to effectively support our AI teams.
