Role: Founding Engineer – Full-Stack with LLM
Location: Remote

Our client is building a new kind of AI-powered journaling and reflection platform — one that feels attuned, emotionally intelligent, and resonant. Their mission is to create emotionally-aware tools that help people better understand themselves.

Position Overview:

As a Founding Engineer, you’ll work closely with the founder to prototype a high-context, interactive journaling system that integrates LLMs, user state modeling, and responsive UX. This role is ideal for an engineer who wants to push the boundaries of human-computer interaction and is excited to build emotionally-intelligent products.

Key Responsibilities:

• Build the product end-to-end: Help architect and implement the core experience using TypeScript, React, Next.js, and Supabase/Postgres.

• Integrate LLMs into user-facing flows: Create emotionally sensitive interactions using OpenAI APIs and state tracking logic.

• Develop lightweight memory/state systems: Build ways to track user sentiment, patterns, and emotional state across sessions.

• Support dynamic UI based on user inputs: Work closely with design to ensure the system reflects and adapts to user tone and needs.

• Prototype quickly, ship with care: Build MVPs that feel thoughtful and intentional — fast, but not sloppy.

Qualifications:

• 3–6+ years of full-stack experience (ideally React/TypeScript)

• Experience with LLM tools (e.g., OpenAI, LangChain, vector databases)

• Strong product intuition and UX sensibility

• Interest in mental health, journaling, inner work, or emotional design

• Bonus: background in NLP, affective computing, or human-computer interaction

What they offer:

• $150-250k, co-founder level equity for the right person
