Job description

About Alaris Security Alaris Security is building the core technology stack for intelligent cyber security. Designed for enterprise and defense organizations, our platform unifies security data through our proprietary graph database and automates critical tasks using our agent framework. Together these technologies allow us to provide a suite of products that enhance defensive cyber security operations, including automating critical use-cases: alert analysis, vulnerability triage, investigations, incident response, and attack staging detection among many others.

About Alaris Security Alaris Security is building the core technology stack for intelligent cyber security.

Together these technologies allow us to provide a suite of products that enhance defensive cyber security operations, including automating critical use-cases: alert analysis, vulnerability triage, investigations, incident response, and attack staging detection among many others. If you've ever wanted to help shape how the world defends itself against cyberthreats, this is your opportunity.

The Role

As an Infrastructure Engineer, you'll architect and lead the systems that power our platform across complex operational environments, ranging from traditional cloud to on-premise and forward-deployed systems.

This is a foundational role. You won't just manage infrastructure, you'll design it from the ground up. You'll own everything from Kubernetes orchestration and secure CI/CD pipelines to infrastructure-as-code, observability systems, and compliance frameworks.

You'll collaborate across engineering to influence product design, support AI workloads, and ensure the infrastructure evolves in step with our most ambitious technical goals. If you thrive in complexity and want to build critical systems with real-world impact, then this is the role for you.

What You'll Do

• Design and implement a robust infrastructure architecture that runs across diverse environments, cloud, on-prem, and constrained, forward-deployed systems
• Own Kubernetes deployments, with a focus on reliability, security, and operational resilience
• Build CI/CD systems that enable rapid iteration without compromising stability or compliance
• Develop infrastructure-as-code using Terraform, Ansible, or similar tools for reproducible provisioning
• Partner with backend engineers to support database performance, availability, and deployment flexibility
• Lead infrastructure initiatives from architecture to rollout, while mentoring junior engineers along the way
• Help define our DevOps culture and influence the long-term technical roadmap of the company

What We're Looking For

• 5+ years of experience in DevOps or enterprise infrastructure roles
• 3+ years deploying and managing production-grade Kubernetes clusters
• Experience working within or adjacent to regulated environments or compliance frameworks
• Deep fluency in building and maintaining CI/CD pipelines
• Proficiency with Terraform, Ansible, or similar infrastructure-as-code tools
• Familiarity with modern observability stacks (Prometheus, Grafana, Datadog, etc.)
• Startup mentality: excited by autonomy, speed, and solving hard technical challenges in real-world systems

Why Alaris

At Alaris, infrastructure isn't a support function, it's mission- critical. The systems you build will run on the edge, in the cloud, and in forward-deployed environments, supporting critical security operations.

This is a rare opportunity to build the infrastructure layer that will be critical for intelligent cyber security. In doing so, you will be on the frontlines of the emerging wave in cyber security and help to defend some of the world's most critical technologies.

If you want to build the invisible machinery that powers the future of defense, we want to hear from you.
