About the role

As a Frontend Engineer Intern, 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.

Responsibilities

• 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

Requirements

• 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 pursuing a degree in Computer Science or a relevant field
• Local to Playa Vista HQ and willing to come into the office 3 days a week

Nice to have

• 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

Benefits

• Hybrid position with in-office work every Tuesday, Wednesday, and Thursday at our Playa Vista, CA office
• Outdoor patio with cabanas, firepits, and working grills
• Breakroom with games, couches, and workout equipment, plus weekly in-office exercise classes (yoga, kickboxing, circuit training)
• Paid charity and volunteer days (local mentor programs, adopt a pet, beach cleanup, etc.)
• Unlimited free snacks and drinks
• Monthly happy hours and catered Thursday lunches
• Monthly team outings (ball games, casino night, hikes, etc.)
• Career growth opportunities with a history of promoting from within
