[Hiring] Software Engineer Intern, UX/DX @Sealed Security

Role Description

We're building a security-focused AI coding agent using Rust and WebAssembly. The product has a working MVP and we're looking for an intern who can contribute real code from week one.

This is a pre-seed venture backed by experienced enterprise software operators, and founded by an ex-Google software engineer.

• You'll work on the developer experience of a Rust-based AI coding agent — the CLI, the terminal output, the way the agent interacts with users.
• This is real engineering work on a real product, not a side project or a learning exercise. Your code will ship to users.
• You'll be working in Rust, building terminal UX, and learning about WebAssembly sandboxing and security models.
• You'll work directly with the founder.

Qualifications

• Rust experience — you've written Rust beyond tutorials. Personal projects, coursework, or contributions to open source. Show us your GitHub.
• AI-native workflow — you actively use AI coding tools (Claude Code, Cursor, etc.) in your daily work and you're genuinely faster because of them.
• Strong code reviewer and architect — this is security software; every line matters.
• Shipped something — at least one project that other people have used. Internships where you shipped code count.
• Comfort with the terminal — you live in the command line, not just visit it.

Requirements

• Previous internship(s) at a software company.
• Experience with terminal UI (ratatui, crossterm, ncurses, etc.).
• WebAssembly familiarity.
• Interest in security, cryptography, or systems programming.

About You

• You're a student or recent grad who builds things.
• Your GitHub has projects with commit histories that show iteration, not just initial dumps.
• You're not a vibe coder; you're an excellent engineer who has adapted to the AI landscape.
• You've done at least one internship where you wrote code that shipped.
• You're excited about Rust, developer tools, and AI — and you want to work at a startup where your work matters immediately.
