The main difference between a Frontend Developer Intern and a Frontend Developer lies in experience, responsibilities, and career stage. Interns are usually students or recent graduates gaining initial industry exposure, while Frontend Developers are experienced professionals handling full project responsibilities.

What does a frontend developer intern do?

A Frontend Developer Intern assists in building and maintaining the user-facing parts of websites or web applications. They typically work with technologies like HTML, CSS, and JavaScript, and may also use frameworks such as React or Angular. Interns collaborate with designers and backend developers to ensure a seamless user experience. Their tasks often include fixing bugs, developing new features, and learning industry best practices.

As a Frontend Developer Intern, you will typically work on real-world web applications or website features, often using frameworks like React, Angular, or Vue.js. You'll collaborate closely with designers and backend developers to implement responsive interfaces and enhance user experience.

Job description

Hi, We're Centerfield!
Supercharged customer acquisition. Centerfield delivers outcome-based digital marketing solutions and personalized omnichannel experiences for the world's leading brands. Powered by our proprietary Dugout platform, Centerfield acquires customers at scale for leading residential service, insurance, e-commerce, and B2B brands. Centerfield's digital experiences and digital brands, such as Business.com and BroadbandNow.com, reach more than 150 million in-market shoppers annually. Centerfield is headquartered in Silicon Beach and is proud to be recognized by Built in LA as a Best Place to Work in Los Angeles.
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
