Role Description We're building a security-focused AI coding agent using Rust and WebAssembly. The product has a working MVP and we're hiring an engineer to bring the developer experience up to speed. This is a pre-seed venture backed by experienced enterprise software operators, and founded by an ex-Google software engineer. - Own the UX and developer experience of a Rust-based AI coding agent. - Make a sandboxed tool feel as polished and responsive as the best developer tools available today. - This is a terminal-first role working across the CLI, the agent loop, and the runtime. - Ship features that developers interact with directly. - This is not a "build from spec" role; you'll have significant autonomy over how features are designed and implemented, working directly with the founder. Qualifications - Strong Rust experience — you've shipped Rust code to production or have substantial open source Rust projects. Show us your GitHub. - Terminal UX sensibility — you care about how CLIs feel, with opinions about input latency, color schemes, and error messages. - 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. - Self-directed — you can take a feature from "we need this" to shipped without detailed specs. Requirements - Preferred WebAssembly experience — Wasmtime, WASI, WIT interfaces, component model. - Experience with ratatui, crossterm, or similar terminal UI frameworks. - Experience with Cap'n Proto or similar RPC/serialization frameworks. - Familiarity with LLM tool-use APIs (Claude, OpenAI, etc.). - Previous startup experience or comfort with ambiguity. Benefits - Competitive compensation, commensurate with experience. - Remote work (US preferred). - Opportunity to work in a fast-paced, innovative environment. - High autonomy in a small team. Company Description AI, sealed and secured.

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.
