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.

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

• 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

• 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/Type Script, 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

• 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

• Experience with cloud platforms (GCP or AWS)

• Understanding of REST APIs and web performance

• Exposure to Vercel, Docker, or modern deployment tooling

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