Senior DevOps Engineer

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. You'll work as a technical peer across DevOps and Engineering, with scope spanning application, cloud, Kubernetes, systems, and network architecture.

You'll 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 you’ll 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.
• Reusable controls and standards improve security consistently across teams and systems.
• Engineering teams trust you as an expert technical peer and involve you early in important design decisions.

What you’ll bring

• 5+ years in Platform, DevOps, SRE, Infrastructure, Cloud Security, or related engineering roles, with meaningful production ownership. 
• Deep security engineering knowledge across application, cloud, Kubernetes, identity, networking, data, and software supply chain.
• Deep cloud and Kubernetes experience; **GCP/GKE strongly preferred**, with equivalent major-cloud experience considered.
• 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.
