Cato Networks is the converged network and security cloud for the AI era.

As AI reshapes cybersecurity, enterprises face a dual challenge: unlocking AI’s potential while defending against AI-driven attacks. Cato addresses both through a unified, cloud-native platform, providing the visibility and context to prioritize risks and stop threats in real time across users, applications, data, and AI agents.

Join us as we scale: take on ambitious technological challenges and shape the next generation of enterprise security at a company trusted by thousands of organizations worldwide.

As part of this exciting journey, Cato recently joined forces with Aim Security — a fast-growing innovator redefining how organizations secure and build with AI.
Backed by Cato’s global reach and powered by Aim’s startup energy, we’re building the future of AI Security together.

The mission is to protect how the world adopts and builds with AI - from the world’s biggest enterprises to fast-moving disruptors. We tackle hard, unsolved problems in AI, cloud, and data security - the kind that shape the next decade of technology. Our products already serve Fortune 500 customers and forward-thinking organizations worldwide, and we’re just getting started.

We’re looking for a Senior Software Developer who combines strong technical skills with product intuition and a sense of ownership. You’ll work across the stack - from infrastructure to backend services and intuitive UI/UX - building scalable, high-impact systems that shape how organizations secure their AI.

What you’ll do

Own and run major features and subsystems end-to-end — you’ll take ideas from concept to production and beyond (monitoring, iteration, refinement).
Work across the full stack: infrastructure, platform, backend services, APIs, and UI/UX. You’ll be comfortable shifting between “how do we deploy this reliably” to “how does the user experience this”.
Drive team culture of ownership, craftsmanship, iteration and delivery: we’re not just about shipping features but owning the outcome, learning fast, and improving continuously.
Mentor and support other engineers: bring in the best practices of maintainability, scalability, reliability, and product thinking.

What you bring

5+ years of hands-on programming in Python, Node.js, or Go (you know one well, and you’re comfortable picking up the others).
3+ years working with AWS, Kubernetes, and RDS (you know your way around cloud-native deployments, scaling, and persistence).
B.Sc. in Computer Science / Engineering or equivalent experience from a technological army unit.
Proven experience leading major projects: you’ve owned significant codebases or systems, taken them from design to delivery, and driven them into production.
Fullstack mindset: you’re comfortable crossing infra/devops/backend/frontend boundaries; you look at problems end-to-end.

Why join us

Be part of a lean, elite team where your work doesn’t just sit in a backlog — you’ll ship real value, frequently, and see the impact.
Bridge the best of startup energy with the scale and reach of Cato Networks: you’ll build for enterprise-grade reliability and commercial scale, and also retain the innovation spirit of a startup.
