About The Position

The Platform Security team sits within NMC²’s Security organization and is responsible for securing the engineering platforms and infrastructure that power our HPC and cloud environment. Our mission is to build real-time security visibility and a proactive vulnerability management capability into the core of how NMC²’s platforms are built and operated — ensuring that security is never an afterthought in an environment where the stakes are exceptionally high. As a Senior Platform Security Engineer, you will play a pivotal role in detecting, assessing, and remediating vulnerabilities across our platform engineering stack from bare-metal infrastructure and container orchestration through to cloud services and software supply chains. You will collaborate closely with Platform Engineering and DevOps teams to embed real-time threat detection and vulnerability management into the development lifecycle, ensuring our infrastructure is resilient, continuously monitored, and hardened against emerging threats.

  • Hands-on experience with vulnerability management tooling and real-time security monitoring platforms (e.g. Qualys, Tenable, Wiz, Lacework, Prisma Cloud, or similar)
  • Strong understanding of software and infrastructure security, including container security, supply chain risk, secrets management, and secure configuration
  • Experience securing container orchestration platforms such as Kubernetes and OpenStack, and cloud environments including AWS and/or Azure
  • Proficiency in Linux and familiarity with how platform engineering teams build and operate infrastructure
  • Experience integrating security tooling into CI/CD pipelines and IaC workflows, with scripting ability in Python, Bash, Go, or similar
  • Good knowledge of vulnerability scoring frameworks (CVSS), exploit maturity, and risk-based prioritization
  • A strong interest in the security domain and a collaborative approach to working with engineering teams to solve complex technical problems

Responsibilities

  • Own the design and operation of NMC²’s vulnerability management program across the platform engineering stack, including infrastructure, containers, and cloud services
  • Implement and tune real-time security monitoring and threat detection tooling, ensuring high-fidelity signal across our HPC and cloud environments
  • Partner with Platform Engineering and DevOps teams to integrate security scanning and vulnerability assessment into CI/CD pipelines and Infrastructure-as-Code workflows
  • Lead vulnerability triage and prioritization, working with engineering teams to drive timely and effective remediation of identified risks
  • Conduct platform-level security assessments, contributing to threat modelling and attack surface analysis across our infrastructure and software supply chain
  • Develop automation to continuously assess the security posture of our platforms, reducing manual effort and improving detection coverage
  • Contribute to the continuous improvement of platform security practices, tooling, and processes, helping foster a security-first culture across engineering
