Careers at Juliet
Build the marketer the next million companies will hire.
I'm a small team building the world's first Built-to-Grow application. We ship every week. We don't pretend to. Real users. Real revenue. Real consequences.
- Now hiringSenior Full-Stack Engineer (AI-native)Full-time · Remote-first · Senior
5+ years · Full-time · Remote-friendly
What you’ll build
An AI-powered coding platform — a browser-based dev environment with an intelligent agent that plans, writes code, and iterates autonomously. Users describe what they want; the agent builds it. Small team, big ambitions: you’ll ship features developers use daily, not write JIRA tickets.
The stack
- Frontend: Next.js 15, React, TypeScript, Zustand, CodeMirror, XTerm.js
- API: NestJS, Supabase, Redis, Server-Sent Events
- AI Agent: Python 3.11, LangGraph, Anthropic & Google model providers
- Infra: Docker, PostgreSQL, Turborepo, pnpm
What you’ll work on
- Agentic AI workflows — multi-step LangGraph agent graphs that plan, write code, run commands, and self-correct across 33+ tools and 17 skill modules
- Real-time streaming — SSE pipelines relaying agent actions from Python through NestJS to the browser, with reconnection, health monitoring, and interrupt handling
- Browser-based dev environments — container lifecycle, file sync, terminal I/O, and live preview via the CodeSandbox SDK
- State & memory systems — LangGraph checkpointers, middleware-injected context, and conversation summarization
- Full-stack product features — collaboration, deployment pipelines, image handling, subscription/quota systems, and onboarding
What we’re looking for
- 5+ years of professional software engineering experience
- Strong TypeScript and Python — you ship production code in both
- React/Next.js experience building complex, stateful UIs
- Familiarity with real-time systems (SSE, WebSockets, streaming APIs)
- You’ve used LLM APIs beyond a chat endpoint — prompt engineering, tool use, agentic patterns
- Solid system-design instincts — you reason about data flow across services
Strong plus
- LangGraph, LangChain, or similar agent-orchestration frameworks
- Developer tools, IDEs, or coding platforms
- Container runtimes or browser-based dev environments (CodeSandbox, StackBlitz, Codespaces)
- NestJS, PostgreSQL, Redis, or Supabase
Apply for this role →Why this role is different
- You’ll shape the product — architecture, agent behavior, and UX directly. Not a feature factory.
- AI-native from day one — the agent isn’t bolted on, it IS the product.
- Depth over breadth — browser containers, streaming infra, agentic AI, and full-stack web all in one system.
- Small team, big leverage — your code ships fast and reaches users immediately.
