Job Description

About the Role

We're looking for a Full-Stack Engineer to build our web application end-to-end and bring the MVP to life. You'll own the user-facing product and the backend that supports it, working closely with the AI Engineer to weave intelligent, real-time AI interactions into a smooth, reliable experience.

What You'll Do

• Build and ship the web application across frontend and backend, from UI components to APIs and data models
• Design and implement a responsive, real-time conversational interface (React, WebSockets/SSE)
• Develop backend services: authentication, session management, data persistence, and third-party integrations
• Integrate AI and multi-agent services into the product in partnership with the AI Engineer
• Design and maintain databases and API contracts that scale with product complexity
• Own performance, reliability, and security across the stack
• Translate product and design requirements into well-tested, maintainable features
• Move fast in an early-stage environment, balancing speed with quality

Qualifications

• 4+ years of full-stack software engineering experience
• Strong proficiency in TypeScript/JavaScript and a modern frontend framework (React preferred)
• Solid backend experience (Node.js, Python, or similar) building and consuming APIs
• Experience designing relational and/or NoSQL data models (PostgreSQL, MongoDB, etc.)
• Familiarity with real-time communication patterns (WebSockets, SSE) and streaming UIs
• Understanding of authentication, authorization, and secure data handling
• Experience integrating third-party APIs, ideally including LLM or AI services
• Comfort owning features end-to-end with minimal oversight

Additional Information

• Experience building with LLM APIs or AI-powered product features
• Familiarity with cloud platforms (AWS/GCP/Azure) and CI/CD pipelines
• Knowledge of caching, queuing, and background job processing
• Prior early-stage startup or 0-to-1 product experience
