Job Description

About Us

Nummi is building what today's AI tools are missing: true  personal intelligence .

While most assistants reset every time you speak to them,  Nummi remembers. It grows with you, understands your workflows, and becomes smarter over time — like a co-pilot that actually  gets you .

We’re rethinking how AI fits into everyday life — and we’re looking for a sharp  AI Engineer to help bring it to life.

🚀  Role Overview

As an AI Engineer at Nummi, you'll work closely with the founding team to design and deploy core intelligence systems — from vector-based memory to real-time, context-aware agents. You’ll be part of the early engineering team, shaping not just product features, but the foundation of what Nummi becomes. This is a 3-month, equity only role with potential conversion to a full-time salaried position. Senior and junior undergraduates are encouraged to apply.

Our Tech Stack

We build with a  modern, performance-first stack :

  • Next.js (App Router)for frontend architecture
  • TypeScript across the stack for safety and speed
  • Tailwind CSS shadcn/ui Radix UI for beautiful UI at scale
  • OpenAI / Foundational Models (GPT-4, Claude, etc.)
  • LangChain Pinecone for vector search & contextual memory
  • Serverless functions for fast and scalable backend logic

🛠  What You’ll Work On

  • Implement AI features like memory graphs, user-specific context, and proactive intelligence
  • Build and optimize RAG pipelines using vector databases
  • Design prompt systems and chain-of-thought logic for multi-turn conversations
  • Collaborate with design and product on user-facing workflows
  • Move fast, iterate often, and ship with care

🧠  What We're Looking For

  • Solid experience with  LLMs and tools like  OpenAI APIs, LangChain, Pinecone
  • Strong grasp of  TypeScript Next.js , and modern web dev principles
  • Understanding of RAG systems, embeddings, and intelligent agents
  • A builder mindset — excited by 0→1 product challenges
  • Bonus: Experience in designing intelligent UI/UX for AI interfaces

🎁 Why Join Nummi?

  • Build with ownership in a fast-growing, founder-led startup
  • Work on problems that blend  AI, memory, personalization, and UX
  • Help shape a product that could redefine how people interact with AI
  • Competitive early-stage equity
