React Developer Intern information

What types of projects and tasks can I expect to work on as a React Developer Intern?

As a React Developer Intern, you'll often collaborate with team members to build and enhance web applications using the React framework. Your daily tasks may include writing and testing components, fixing bugs, and participating in code reviews. Interns are typically assigned smaller features or user interface improvements, but you may also assist with integrating APIs or optimizing app performance. The environment is usually supportive, offering mentorship and opportunities to learn best practices in modern frontend development.

What are the key skills and qualifications needed to thrive as a React Developer Intern, and why are they important?

To thrive as a React Developer Intern, you need a solid understanding of JavaScript, React fundamentals, HTML, CSS, and basic software development principles, often gained through coursework or self-study. Familiarity with version control systems like Git, code editors such as VS Code, and package managers like npm or yarn is typically expected. Strong problem-solving abilities, eagerness to learn, and effective communication skills help interns stand out in collaborative tech environments. These skills and qualities are crucial for efficiently building user interfaces, adapting to new technologies, and contributing to team projects.

What does a React Developer Intern do?

A React Developer Intern assists in building and maintaining web applications using the React.js library. They typically work under the guidance of senior developers to implement user interfaces, fix bugs, and write clean, reusable code. Interns may also participate in code reviews, testing, and learning about front-end development best practices. This role is ideal for students or recent graduates looking to gain practical experience in web development.

What is the difference between React Developer Intern vs Front-End Developer?

Common Search & ComparisonYesYes

The React Developer Intern role is typically an entry-level, temporary position aimed at gaining hands-on experience with React.js.

Both roles share similar credentials and work environments, but differ mainly in experience level and job permanence.

Job description

Pylon - the agentic support platform purpose-built for B2B.
Pylon is the only agentic support platform, purpose-built for B2B companies. For leaders scaling AI-native support teams, Pylon lets humans and agents collaborate on customer work - investigating, resolving, and acting on every signal across every channel that matters.
Unlike platforms built before the AI era, Pylon enriches every interaction with deep account-level context, automates the low impact customer work, and surfaces answers before your team even has to ask. The result: faster responses, happier customers, and a system that continuously improves itself.
We're backed by a16z, BCV, General Catalyst, and Y Combinator. More than 1,500 companies including Linear, Cognition (makers of Devin), Modal Labs, and Incident.io run their support and customer success workflows on Pylon. We're also featured on the Enterprise Tech 30 List.
What You'll Do
  • Build features so our customers in post-Sales roles (Customer Support & Customer Success) run their operations more efficiently by leveraging AI
  • Build prototypes, work independently, iterate quickly, and ship fast
  • Have high autonomy, own things end to end, and project manage your own work
  • Work with PMs, designers, and other engineers in a highly collaborative, non-waterfall way
  • Collaborate with a strong technical team of senior engineers from places like Samsara, Affinity, Airbnb, and Meta

What We're Looking For
  • You are pursuing a bachelor's or master's degree in computer science, engineering, or another related field and are graduating between December 2026 and Summer 2028.
  • You have a growth mindset, want to constantly improve, and want to receive feedback
  • You're in SF or you're willing to relocate (the internship will take place in Summer 2027)
  • (Bonus) You have relevant internship experience or side projects building product features and a demonstration of strong full-stack fundamentals
  • (Bonus) You have interned at high-growth startups and can navigate ambiguous environments.
  • (Bonus) You highly leverage AI for software development and can juggle multiple workstreams at the same time.
  • (Bonus) You have experience with our tech stack (React, Golang, GraphQL, and AWS).

Our Perks
Commuter benefits
Parental leave
14 company holidays + unlimited PTO
Annual offsite
Lunch, dinner, and snacks at the office
Fitness stipend

Funding: Series B led by a16z and BCV ($51M total raised)
