Entry-Level Software Engineer, Rust UXDX

Type: Contract (3-6 months potential conversion to full-time)

Location: Remote (US preferred)

Compensation: Competitive commensurate with experience

Start Date: ASAP

Were building a security-focused AI coding agent using Rust and WebAssembly.

The product has a working MVP and were 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.

Tasks

Youll own the UX and developer experience of a Rust-based AI coding agent making 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 shipping features that developers interact with directly.

This is not a build from spec role. Youll have significant autonomy over how features are designed and implemented working directly with the founder.

Requirements

Required:

• Strong Rust experience youve 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. You have 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 youre genuinely faster because of them. But youre also a strong code reviewer and architect. This is security software every line matters. We want AI-augmented engineers not vibe coders.
• Self-directed you can take a feature from we need this to shipped without detailed specs.

Preferred:

• WebAssembly experience Wasmtime WASI WIT interfaces component model
• Experience with ratatui crossterm or similar terminal UI frameworks
• Experience with Capn Proto or similar RPC/serialization frameworks
• Familiarity with LLM tool-use APIs (Claude OpenAI etc.)
• Previous startup experience or comfort with ambiguity

About You:

Were targeting someone early in their career with disproportionate output a recent grad or early-career engineer with a GitHub profile that shows real projects not just coursework. Previous internships at companies that ship software. The kind of person who builds things on weekends because they want to not because they have to. Youre not a vibe coder youre an excellent engineer who has adapted to the AI landscape.

You should be excited about:

• Working in Rust full-time
• Building developer tools
• The intersection of security and AI
• Shipping fast in a small team with high autonomy
