We're hiring on behalf of a cutting-edge tech company that's reimagining how software gets built - combining full-code flexibility with the power of no-code tools and generative AI into a unified platform.

You'll work on a tool that lets developers and teams create UIs, workflows, and backends - faster and smarter. Think: Python interpreter + visual UI + no-code workflows + GenAI.

This role suits engineers with strong Python and frontend experience (Vue + TypeScript preferred, React is fine too), and a passion for building tools for developers.

• Build core parts of their low-code UI and no-code workflow builder
• Shape backend architecture with Python (Pydantic, Mypy, Pytest, etc.)
• Contribute across both frontend and backend
• Define engineering best practices for typing, testing, CI/CD, and code quality
• Integrate AI agent tooling and third-party APIs
• Collaborate with product, design, and infra teams to build real-time collaboration features

Qualifications

• 1+ year of fullstack experience (open to senior/staff-level engineers too)
• Production experience with Model Context Protocol (MCP) is highly desired
• Experience working with LLMs, RAGs, Langchain, OpenAI, Claude etc is beneficial
• Generative AI Product experience
• Production-grade Python skills
• Frontend experience with Vue + TypeScript, or React and a willingness to learn Vue
• Understanding of web performance, testing, REST APIs, OAuth
• Comfort working in fast-paced, ambiguous environments
• Bonus: experience with devtools, no-code/low-code, AI tools, or OSS contributions
