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

2d ago - Sealed Security is hiring a remote Software Engineer Intern, UX/DX. πŸ’Έ Salary: paid, competitive for internship level πŸ“Location: USA

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 β€” 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 β€” you've written Rust beyond tutorials. Personal projects, coursework, or contributions to open source. Show us your GitHub.
  • AI-native workflow β€” 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 β€” this is security software; every line matters.
  • Shipped something β€” at least one project that other people have used. Internships where you shipped code count.
  • Comfort with the terminal β€” 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 β€” and you want to work at a startup where your work matters immediately.

Company Description

AI, sealed and secured.
