About The Position

In this position, you will be a key contributor to building and enhancing the digital backbone of Athlete To Athlete. We are looking for an "AI-First" engineer—someone who doesn't just write code, but leverages the latest in Generative AI to accelerate development cycles and builds intelligent features that redefine youth sports mentorship.
You will work across our entire stack, from crafting responsive customer-facing interfaces to architecting robust APIs and AI-driven backend logic. This role requires a deep understanding of full-stack development combined with a passion for integrating Large Language Models (LLMs) and AI tools into the product and the development workflow itself. You will own projects from ideation to deployment, seeing your impact on our athletes and mentors in real-time.
As a core member of a lean startup team in Santa Monica, you’ll collaborate with marketing, sales, and operations to build systems from the ground up that are smarter, faster, and more scalable than traditional architectures.
This is an hybrid/on-site position based in Santa Monica.

• Frontend Mastery: Deep experience with React and Next.js.
• Backend Proficiency: Familiarity with Python and Django (or a strong desire to master them quickly).
• Data Fluency: Comfortable with Postgres or other relational database systems.
• Agile Problem Solving: Strong communication skills and the ability to pivot quickly in a fast-paced startup environment.

• Marketplace Experience: Previous work building two-sided marketplaces.
• Infrastructure: Experience managing AWS or other cloud providers.
• Startup Grit: Previous experience in early-stage companies where you wore many hats.
• The Athlete’s Edge: Experience as a college athlete or a deep passion for the youth sports ecosystem.

Responsibilities

• AI-Driven Development: Utilize AI coding assistants (e.g., Cursor, Claude Code) to maintain high-velocity output and ensure code quality, while staying updated on the latest AI development trends.
• Product Intelligence: Design and implement AI-powered features, such as personalized mentor matching, automated content moderation, and intelligent communication tools for athletes.
• Full-Stack Engineering: Build and maintain robust web applications and websites using React/Next.js, eventually expanding into native mobile environments.
• Backend & API Architecture: Develop scalable APIs and backend services in Python/Django, integrating third-party AI APIs (Vertex AI, etc.) to enhance platform capabilities.
• Data Stewardship: Design and optimize Postgres databases to manage data securely, ensuring our data architecture is "AI-ready" for future training or RAG (Retrieval-Augmented Generation) implementations.
• Cross-Functional Optimization: Partner with teams across the company to automate internal workflows using AI, streamlining the customer lifecycle and operational efficiency.
