Job description

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 2025.)

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 https://mountain.com/.

We are seeking an experienced Senior Security Operations Engineer to lead and scale our security operations. You will be responsible for safeguarding our systems, networks, and data from cyber threats. This role requires a deep understanding of security monitoring, incident response, and automation, along with the ability to collaborate cross-functionally with IT, engineering, and compliance teams.

What you'll do
  • Lead day-to-day security operations, including monitoring, detection, investigation, and response to security incidents.
  • Understanding modern cloud infrastructure stacks and injecting security controls in those stacks. Terraform, Kubernetes, CI/CD, ArgoCD, Github for example.
  • Develop, refine, and maintain SIEM rules, alerts, dashboards, and playbooks for proactive threat detection.
  • Drive incident response efforts, including triage, containment, eradication, recovery, and post-incident reporting.
  • Automate repetitive SecOps processes (e.g., enrichment, remediation, alert triage) to improve efficiency and reduce noise.
  • Conduct threat hunting activities to identify hidden threats and vulnerabilities.
  • Collaborate with devops and engineering teams to embed security best practices into systems and workflows.
  • Perform log analysis and security monitoring across cloud, endpoint, and network environments.
  • Lead security assessments and participate in vulnerability management and remediation programs.
  • Partner with compliance and risk management teams to support audits and regulatory requirements.
What you'll bring
  • 5+ years of hands-on experience in Security Operations
  • Strong knowledge of SIEM platforms
  • Expertise in threat detection, malware analysis, and forensic investigation.
  • Proficiency with scripting and automation tools (Python, Bash, etc.).
  • Solid understanding of network protocols, firewalls, IDS/IPS, EDR, and cloud security controls.
  • Experience with cloud platforms (AWS and GCP) and their native security services.
  • Familiarity with MITRE ATT&CK, NIST, ISO, and other security frameworks.
  • Excellent communication and leadership skills, with experience guiding teams or projects.
  • Security certifications a plus
