Who We Are

At Robyn AI, we’re on a mission to build a more emotionally connected world. We believe in creating products that transform the way people connect and engage. We are backed by elite investors, including M13, Lars Rasmussen (cofounder of Google Maps), Bill Tai (seed investor in Zoom and Canva), and Christian Szegedy (cofounder of X.ai), with $5.5M raised to date.

Robyn is not just an AI app — she’s your emotionally intelligent companion. A trusted mirror. A guide. A new kind of OS for your emotional life.

We're building the world’s first emotional intelligence layer for AI.

As a Founding Backend Engineer, you’ll be building the backend infrastructure that powers all of it:

• Conversations, memory, and real-time personalization
• Voice + chat interface
• Scalable infra for emotional intelligence
• Secure and fast APIs for our iOS app
• A robust ML inference and fine-tuning pipeline

You’ll be the technical backbone of Robyn — designing and shipping fast, scalable, emotionally aware systems while collaborating closely with iOS, product, and AI teams.

What You’ll Own

1. Backend & Infra Architecture

• Refactor our current C# / .NET Core backend into Python (FastAPI) with modular architecture for scale.
• Build robust REST and GraphQL APIs consumed by iOS; optimize for latency, resilience, and observability.
• Deploy and orchestrate microservices on AWS (EKS) using Docker, Kubernetes, and Terraform.
• Own CI/CD, monitoring, logging, and incident response — full backend autonomy.

2. AI & ML Systems Integration

• Manage vector databases (e.g. Redis Vector, Pinecone) for RAG, memory, and personalization.
• Build and maintain pipelines with LangChain, integrating LLMs (GPT-4o, Claude, Llama 3, etc.).
