The Opportunity...

As a Frontend Engineer Intern at Centerfield, you'll join our engineering team building intuitive, high-performance consumer-facing web interfaces used by millions of shoppers. You'll ship real features - building new applications from scratch and extending or redesigning existing products, contributing to high-traffic sites like Savings.com.

Our team practices AI-first development: engineers act as architects who direct AI agents, custom skills, and automated workflows to deliver production software. You'll learn to go beyond out-of-the-box tools like Claude Code or Codex - building custom agents, domain knowledge systems, and review processes that turn AI into a force multiplier. We care less about clever code and more about delivering business value.

How You'll Contribute...

• Build and ship consumer-facing web applications and features, from greenfield builds to redesigns of existing high-traffic sites

• Develop responsive, accessible front-end experiences using React, Next.js, and TypeScript, integrating seamlessly with back-end APIs (Node.js, Java)

• Use and extend our custom AI development harness: agents, skills, and workflow commands to accelerate delivery

• Experiment with new ways to apply AI agents to real engineering problems, and share what works with the team

• Collaborate with product, design, and engineering to turn business goals into shipped features

• Participate in the full software development lifecycle: design, build, review, ship, iterate

What We're Looking For...

• Genuine curiosity and open-mindedness about AI-driven development. You actively experiment with AI agents and tools, and can show us something cool you've built with them

• Solid understanding of modern front-end development: React, JavaScript/TypeScript, HTML5, and CSS/Tailwind.

• Exposure to frameworks and runtimes like Next.js and Node.js

• Understanding of APIs and how front-ends talk to back-end services

• Knowledge of software fundamentals: source control, debugging

• Rising seniors or new graduates (update year as needed)

• Local to Playa Vista HQ and willing to come into the office 3 days a week

• Pursuing a degree in Computer Science or a relevant field

Bonus Points!

• A portfolio, repo, or demo of something you built primarily with AI agents — bonus if you customized the workflow (custom agents, skills, prompt systems, MCP servers, evals)

• Experience with cloud platforms (GCP or AWS)

• Understanding of REST APIs and web performance

• Exposure to Vercel, Docker, or modern deployment tooling

Intern Life at Centerfield…

• This is a hybrid position, and employees are expected to work in our Playa Vista, CA office every Tuesday, Wednesday & Thursday.

• Outside patio overlooking Playa Vista + cabanas, firepits & working grills.

• Breakroom supplied with games, couches, workout equipment + weekly in-office exercise classes hosted by professional instructors (yoga, kickboxing & circuit training).

• Paid charity and volunteer days (local mentor programs, adopt a pet, beach cleanup, etc.).

• Unlimited free snacks and drinks around the office!

• Monthly happy hours, catered Thursday lunches.

• Award-winning culture & unprecedented team spirit (featured in LA Business Journal & Built In LA Best Places to Work).

• Monthly team outings (ball games, casino night, hikes, etc.).

• Career growth – we enjoy promoting from within
