This is a senior hands-on security engineering role focused on continuously improving the security posture of the MNTN platform through architecture automation and platform engineering. Youll work as a technical peer across DevOps and Engineering with scope spanning application cloud Kubernetes systems and network architecture.

Youll combine hands-on work with individual teams and internal consulting to shape secure designs solve complex problems and turn recurring risks and requirements into secure defaults reusable controls self-service platform capabilities and automated security observability. The goal is to make strong security practices consistent measurable and easy to adopt across Engineering.

This is not a GRC or audit role. Your impact comes from deep technical judgment effective collaboration and making good security decisions repeatable across the organization.

What youll do

• Shape security architecture across applications cloud infrastructure Kubernetes networking CI/CD identity and data flows.
• Partner with engineering teams on architecture and threat modeling helping design secure systems before they ship.
• Turn security requirements and recurring risks into secure defaults reusable platform capabilities policy-as-code and automated enforcement. Build automated security monitoring and response including CVE detection prioritization remediation verification alerting and visibility into control failures.
• Design and operate secure infrastructure primarily on **Google Cloud and GKE** using Kubernetes as the core platform abstraction.
• Implement and evolve controls for IAM/RBAC workload identity least privilege secrets environment isolation network segmentation container security and software supply chain.
• Build automation infrastructure tooling and CI/CD systems using GitOps Terraform / OpenTofu Crossplane Argo APIs SDKs and code.

What success looks like

• Security is addressed through architecture and platform design not one-off fixes.
• Secure defaults and self-service capabilities make strong security practices easy to adopt.
• Security risks and control failures are visible through automated monitoring and actionable alerting.

• Strong understanding of application and systems architecture APIs authentication/authorization distributed systems networking and trust boundaries.
• Strong software engineering and automation skills in Python and Typescript including APIs SDKs CLIs and internal tooling.
• Deep Terraform / OpenTofu and Kubernetes experience including reusable infrastructure patterns GitOps Helm ArgoCD RBAC and workload security.
• Experience with threat modeling security observability and translating security or compliance requirements into practical technical controls.
• A platform mindset: you solve recurring problems with abstractions paved roads automation and self-service rather than manual processes.
• Comfortable using AI-assisted engineering tools daily while independently validating correctness security and operational impact.
• Able to operate independently consult effectively with engineering teams communicate architectural tradeoffs and influence senior technical peers.
