Platform Engineer

We are seeking a Platform Engineer to take ownership of deploying, managing, and evolving our multi-prem platform architecture across diverse customer environments, from bare-metal data centers to commercial and IL5, IL6, and IL6+ environments.

You’ll play a critical role in bridging our continuously deployed SaaS platform with shrink-wrapped customer-hosted releases, ensuring alignment, consistency, and operational excellence across all footprints.

This is a deeply technical role that sits at the intersection of infrastructure, networking, Kubernetes, and secure automation, ideal for engineers who thrive in complex, regulated, and hybrid environments.

Hidden Layer protects the world’s most valuable technologies from adversarial AI attacks. We were founded by AI professionals and security specialists with first‑hand experience of how insidious adversarial AI attacks can be to detect and defend against. Determined to prove that these attacks were preventable, the team developed a unique, patent‑pending, productized solution to support organizations in accelerating their adoption of AI securely.

Our dedication to innovation has been recognized by prestigious awards such as RSA's Innovation Sandbox Winner, CB Insights AI 100, Cyber Tech 100, and SC's Most Promising Early-Stage Start‑up.

• Lead deployment and lifecycle management of our multi‑prem platform across commercial cloud, bare‑metal, air‑gapped, and IL4+ environments.
• Build and maintain infrastructure‑as‑code (Terraform, Helm, ArgoCD, etc.) to automate consistent deployments across customer sites.
• Ensure our customer‑hosted builds (“shrink‑wrapped” software) remain closely aligned with our continuously deployed SaaS platform.
• Maintain and optimize Kubernetes clusters and container build pipelines (EKS, K0s, AKS, or on‑prem distributions).
• Implement secure and reproducible container image build pipelines, aligned with our internal release processes.
• Collaborate with Engineering teams to harden deployments for regulated, classified, and air‑gapped customer systems.
• Document and version deployment patterns, templates, and procedures to support both automation and accreditation workflows.
• Support incident response, troubleshooting, and upgrade cycles across multiple platform footprints.
• Contribute to the overall architecture and evolution of the multi‑prem reference design, ensuring scalability, reliability, and security parity with SaaS.

• U.S. Citizen (required) and eligible for U.S. Government clearance (Secret or higher preferred).
• Proven success deploying and operating complex systems across multi‑cloud and on‑prem environments.
• Deep hands‑on expertise with Kubernetes orchestration, container pipelines, and infrastructure automation (Terraform, Helm, ArgoCD).
• Strong foundation in networking concepts: DNS, routing, VPC design, VPNs, firewalls, and service meshes.
• Proficient with secure CI/CD pipelines (Git Hub Actions).
• Experience maintaining Linux systems, observability stacks (Prometheus, Grafana, Loki, Open Search), and automation tooling.
• Familiarity with compliance frameworks such as FedRAMP, DoD SRG, or NIST 800-53.

• 5+ years of experience in platform, Dev Ops, or infrastructure engineering.
• Experience deploying workloads into AWS Gov Cloud, Azure Government, or other regulated cloud environments.
• Experience deploying and maintaining software in classified, air‑gapped, or disconnected environments.
• Knowledge of supply chain security (SLSA, SBOM, image signing, provenance).
• Background in AI/ML or data‑centric security platforms is a plus.
• Familiarity with Temporal, Kafka, or distributed systems architecture.
• Experience maintaining multi‑tenant platform parity between SaaS and…
