Senior DevOps Engineer Austin, TX

At MNTN, we put our people first, full stop. This allows our company culture to be defined by our team members and their shared values, like trust, ambition, quality, radical honesty, and compassionate leadership. It’s why we all really love working for the Hardest Working Software in Television (and also why we were named one of Ad Age’s Best Places To Work in 2026.)

We pride ourselves on bringing unrivaled performance and simplicity to Connected TV advertising. Our self‑serve technology makes running TV ads as easy as search and social, helping brands drive measurable conversions, revenue, site visits, and more. It’s what led MNTN to being named one of Fast Company's Most Innovative Companies in 2023. You can learn more about us and everything we do by visiting  .

So if wanting to do more, own more, and make a bigger impact comes naturally to you, then you may be the person we're looking for to join us in our next stage of growth.

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 Dev Ops 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.

• 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 Git Ops, Terraform / Open Tofu, Crossplane, Argo, APIs, SDKs, and code.

• 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.

• 5+ years in Platform, Dev Ops, 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,…
