Job description

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.

If you've ever wanted to help shape how the world defends itself against cyberthreats, this is your opportunity.

The Role

As a Full-Stack Engineer at Alaris, you'll be building the tools that make the future of cyber security possible. One day you might be designing a frontend that lets analysts visualize real-time threats across a global infrastructure. Next, you might be crafting backend systems that orchestrate autonomous AI agents to investigate threats as they unfold.

This is a high-ownership role: you'll work across the stack, propose new features, improve core infrastructure, and shape product direction. You'll collaborate with a small, elite team of engineers and security experts to solve some of the hardest problems in the field.

What You'll Do

• Build powerful, intuitive user-facing features using TypeScript and Next.js
• Extend backend systems and design database schemas to support intelligent automation
• Architect and refine AI agents to handle high-value security workflows
• Design APIs and coordinate backend/frontend interfaces for new platform features
• Contribute to system-level architecture and make decisions that will scale with the company
• Work closely with engineers, designers, and security specialists to build a unified product
• Help shape the culture of an early-stage, mission-focused engineering team

What We're Looking For

• 3+ years of software development experience
• Deep comfort across the stack, from frontend to backend to architecture
• Experience building and shipping full-stack applications
• Strong React and TypeScript experience (Next.js is a plus)
• Passion for solving hard problems with clean, scalable solutions
• Comfortable working independently and driving projects from start to finish
• Experience with PostgreSQL based databases
• Bonus: experience with AI agents, graph databases, or cyber security products

Why Alaris

We are at a rare point in time (the 3rd generation of cyber products) where we can build with AI at the core. At Alaris, you'll work at the intersection of cyber security, AI, and systems design. This is a rare chance to build foundational technology that will shape the future of enterprise and national security.

You won't just be writing code—you'll be building defense systems for the future of the world.
