Job Description
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. Company Description AI, sealed and secured.
