The Company
NorthMark Compute & Cloud (NMC²) is backed by dedicated leadership and investment, with a clear mission as it operates at the bleeding edge of technology. Its goal is to scale and enhance the high-performance computing (HPC) and cloud infrastructure that supports its clients’ research, production, and delivery, enabling breakthroughs that shape the industries of tomorrow. Its engineers build critical infrastructure to eliminate friction in scientific research, simulations, analysis, and decision-making, accelerating discovery and driving faster innovation.
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.
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
Requirements:
6+ years of experience in security engineering, with a strong focus on platform, infrastructure, or application security
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
Nice to Have:
Experience with runtime threat detection tools such as Falco or eBPF-based security tooling
Familiarity with software supply chain security frameworks (e.g. SLSA, SBOM generation, Sigstore)
Background working within or alongside a SOC or threat intelligence function
Relevant certifications such as OSCP, GIAC (GPEN/GWAPT/GCSA), AWS Security Specialty, or equivalent
