Frontend Engineer Intern (6 month internship)

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.

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

At Centerfield, we use AI tools internally to support efficiency and fairness in our hiring process, including resume screening and administrative tasks.

Candidates are welcome to use AI tools ethically to prepare for interviews, such as practicing responses or researching questions. However, all responses during the interview process should reflect your own knowledge, experience, and judgment.

The use of AI tools to generate responses during live interviews, technical assessments, or written submissions is not permitted unless explicitly stated otherwise.

Interviews will take place after resumes have been screened for the minimum requirements. Please note that this position is not restricted solely to the responsibilities listed above and that the job scope and responsibilities are subject to change.
