We are looking for a Full-Stack Engineer with 4-6 years of experience to take on a critical, high-ownership role at our seed-stage AI startup. You'll be a senior member of our engineering team, helping to define our product direction and mentor talented junior engineers. We need a product-minded builder who can own features end-to-end and help us scale our AI-powered marketing platform for a growing waitlist of clients.

What will you be doing?

Design and implement RESTful APIs (FastAPI) with well-structured Pydantic schemas, ensuring backward compatibility as the product evolves.
Build and maintain React/TypeScript frontends with modern state management (Zustand, TanStack Query) and Tailwind CSS.
Work with Django ORM and PostgreSQL for complex data modeling — multi-tenant architecture, canvas/widget systems, versioned content, and template provisioning.
Write and maintain frontend and backend unit tests.
Collaborate on infrastructure using Docker, GCP (Cloud Run, GKE), Terraform, and GitHub Actions CI/CD pipelines.
Perform data operations — writing and reviewing SQL for migrations, debugging data inconsistencies across environments (staging/production).
Collaborate closely with a small, stellar team to solve complex challenges in the $1T performance marketing industry.

MAI was founded by technologists and operators who spent over a decade building ad platforms and e-commerce engines. They saw that growth-stage businesses often lacked access to the advanced growth technology powering the largest platforms, and set out to change that. Today, a rapidly growing network of D2C brands and apps rely on MAI’s intelligent agents to simplify marketing complexity, uncover actionable insights, and autonomously drive measurable results. Backed by Tier-1 VCs, MAI is pioneering autonomous growth agents that bring advanced data science and machine learning to every business, and work around the clock to help them reach their full growth potential.

We just announced a $25M Seed round led by Kleiner Perkins.
We're building AI agents to transform the performance marketing industry; a massive $1T market. Video here by our CEO/Founder, former VPE at Instacart.
Our SMB customers are already seeing results (40% lift) with a growing client waitlist by the day.
Most importantly, the team is stellar, solid human beings, and amazing at what they do - you’re going to have a lot of fun.
