Frontend Engineer Intern

About Us

At Armadin, we're a group of engineers, researchers, and security researchers on a mission to redefine what proactive security can do in the AI era. Cyberattacks are becoming autonomous and relentless and we believe defending against threats before they materialize is one of the most powerful ways to protect the institutions the world depends on.

We're building autonomous proactive security from the ground up, reinforcing the tradecraft of elite security practioners into purpose-built security models and agents that discover risk and remediate it before organizations are breached.

Led by Kevin Mandia, founder of Mandiant ($5.4B exit to Google), our team brings together researchers and engineers from Google, xAI, Meta, Stanford, Georgia Tech, Waterloo, Berkeley, and MIT to reinvent security for an adversary that never sleeps.

The Role

As a Frontend Engineer Intern on the Product & UX/UI team, you'll help turn complex security data and graph information into clear, navigable interfaces that make sophisticated, AI-integrated security workflows accessible to the people relying on them. You'll ship production code alongside full-time engineers from day one, paired with a mentor invested in your growth, and see your work deployed to real customers rather than left in a sandbox.

We're a small, fast-moving team, so interns get real ownership: you'll work across the stack, from polished React interfaces to the full-stack systems that power them, and you'll partner directly with founders, product, and design to understand the problems worth solving.

What You'll Do

• Transform complex security data and graph information into clear, navigable user interfaces.

• Collaborate with product and design to make sophisticated, AI-integrated security workflows accessible.

• Contribute to scalable frontend and full-stack systems, balancing polish, performance, and reliability.

• Pair with a dedicated mentor and take part in code reviews and design collaboration.

• Participate in design reviews, code reviews, and team rituals just like a full-time engineer.

Required

• Currently pursuing a Bachelor's degree in Computer Science, Software Engineering, Math, or a related technical field, with an expected graduation in 2027 or 2028.

• Comfortable writing clean, well-tested code and picking up new languages and frameworks quickly.

• Solid foundation in data structures, algorithms, and distributed systems fundamentals.

• Prior experience with Python, Go, or with LLM/agent frameworks is a plus.

Nice to Have

• Experience with data visualization or graph rendering (D3 or similar).

• Exposure to building products that emphasize reliability and scalability.

• Open-source contributions, hackathon projects, or independent builds that show initiative.

Technologies We Use

• Our stack centers on React and TypeScript for the frontend, Node.js and Python for full-stack services, and D3 (or similar) for rendering complex security and graph data.

• We care more about your ability to learn than the specific frameworks on your resume.
