Full-stack Engineer

At MAI (pronounced “my”), we're on a mission to democratize advanced advertising technology. We believe that cutting-edge marketing tools, once exclusive to large enterprises with massive budgets, should be accessible to everyone. Our platform uses AI agents to automate and optimize performance marketing, empowering small and mid-sized businesses to scale their ad spend profitably without the need for an agency or endless hours of manual campaign management.

Founded by ad platform veterans from Google and Instacart, we've successfully raised a $25 million Seed funding round led by Kleiner Perkins to accelerate our growth. This capital will be used to expand our product and engineering teams, bringing our vision of intelligent, autonomous marketing to life. Our AI agents have already proven their value, helping clients drive 40% more sales and managing millions in monthly Google Ads spend. Our client waitlist is growing by the day.

We're building an AI-powered marketing optimization platform that helps clients improve ad spend efficiency across channels like Google Ads and Meta. You'll work across the full stack — from designing APIs and data models to building interactive dashboards that surface AI-driven insights to end users.

This is a high-ownership role. You'll be involved in feature design, implementation, deployment, and iteration based on real user feedback.

• 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).

• 3+ years of professional experience building and shipping fullstack web applications.

• Strong proficiency in Python (FastAPI or similar async frameworks, Django ORM, Pydantic).

• Strong proficiency in TypeScript/React with modern patterns (hooks, server state management, component composition).

• Solid understanding of relational databases (PostgreSQL) — schema design, query optimization, migrations.

• Experience with REST API design — versioning, backward compatibility, proper error handling.

• Comfortable writing unit tests and working with CI/CD pipelines.

• Ability to reason about multi-tenant data isolation and safely operate across client boundaries.

Bonus points for experience in any of the following:

• Experience with GCP services (Cloud Run, GKE, VPC, Private Service Connect).

• Familiarity with Terraform for infrastructure-as-code.

• Experience with ad tech / marketing platforms (Google Ads API, Meta Marketing API).

• Exposure to AI/ML product development — integrating model outputs into user-facing features.

• Experience with sandbox/code execution environments.

• Familiarity with Python tooling: Poetry, Ruff, Mypy, pre-commit hooks.

• High Autonomy: You'll own features end-to-end, from API schema design to frontend UX.

• Fast Iteration Cycles: We ship frequently and adjust based on ops team and client feedback.

• Direct Involvement in Production Operations: You'll write SQL, debug staging issues, and help onboard clients.

• Close Collaboration: Work with a small team where code quality, clean abstractions, and pragmatic trade-offs matter more than ceremony.

We're offering a stake in our success and a commitment to your well-being. Our total compensation package is designed to support you, both professionally and personally:

• Salary: Depending on your years of experience, a base salary range of $160,000 to $225,000.
