Software Engineer Intern, Rust UX/DX
Sealed Security
Company: Sealed Security Type: Internship (3 months, potential extension or conversion) Location: Remote (US preferred) Compensation: Paid, competitive for internship level Start Date: ASAP 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. Tasks 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. Requirements Required: - 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. But you're also a strong code reviewer and architect. This is security software — every line matters. We want AI-augmented engineers, not vibe coders. - 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. Preferred: - 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.
