What is a frontend engineer intern?

Frontend Engineer Interns are entry-level professionals or students who assist in developing the user-facing parts of websites and web applications. They work closely with experienced frontend engineers to implement visual elements, improve user experience, and ensure responsive design using technologies like HTML, CSS, and JavaScript. Interns may also collaborate with designers and backend developers to integrate APIs and deliver interactive features. This role is designed to provide hands-on learning and exposure to industry best practices in frontend development.

What types of projects and tasks can I expect to work on as a frontend engineer intern?

As a Frontend Engineer Intern, you will typically assist with developing user interfaces, fixing bugs in existing code, and implementing new features under the guidance of senior engineers. You may work on tasks such as translating design mockups into responsive web pages, optimizing website performance, and collaborating with designers and backend developers to ensure a seamless user experience. Interns often participate in code reviews and sprint planning meetings to gain exposure to agile development processes. This hands-on experience is invaluable for building your technical skills and understanding the collaborative nature of software development teams.

What are the key skills and qualifications needed to thrive as a frontend engineer intern?

To succeed as a Frontend Engineer Intern, a solid understanding of HTML, CSS, JavaScript, and basic web development concepts is essential, often backed by coursework or personal projects. Familiarity with frameworks like React or Vue.js, version control systems such as Git, and basic debugging tools is highly beneficial. Strong problem-solving skills, attention to detail, and effective communication set standout candidates apart in collaborative tech environments. These competencies ensure interns can contribute meaningfully to projects, adapt quickly to new technologies, and work efficiently within a development team.

Software Engineering Intern [Fall/Winter 2026]

New York, NY • On-site

Full-time, Per diem, Internship

Posted 9 days ago

Job description

Melius - New York City
Engineers have Cursor. Lawyers have Harvey. The office of the CFO has Ramp. Every knowledge profession has been handed a platform that lets them orchestrate agents and scale their output by an order of magnitude - except the people who actually make the things we look at, watch, and listen to.
Melius is the agents lab for creative work. We build agentic interfaces to all the work that goes into building the next generation of images, video, audio and so much more. Generative media canvas, timeline editor, asset manager, and much more, built native for agents. Using Melius, users can spend more time being creative and let go of the century old legacy tools that only acted as constraints to their imagination.
We're backed by General Catalyst, Vine Ventures, Genius Ventures, and Antifund, and built by a team of second-time founders, former engineering leaders from Ramp, and operators who came up through top-tier VC and PE. We move fast, ship every day, and have strong opinions about craft.
The role
This is not a "summer project" internship. Expect to be treated exactly as a full time engineer would be from the first day at your job. There will be dozens of projects that you lead and are expected to educate both customers and other members of the team on.
The stack: Next.js and a real-time CRDT canvas on the frontend, NestJS / MikroORM / Postgres / Temporal / Turbopuffer on the backend, and the agent and model orchestration layer that ties it all together.
High level activities for the internship might include:
  • Building new tools for our agent end-to-end - what it can do on the canvas, what it can change in the timeline editor, and how it can semantically search in the asset manager.
  • Sitting in on user sessions, watching a creative hit a rough edge, and shipping the fix that same hour.
  • Adding evals and traces that tell us, honestly, whether the agent got better this week.
  • Polishing canvas interactions that thousands of creatives touch every day - the small details users never explicitly notice but always feel.

You'll work directly with senior engineers and the founders. Expect fast feedback, real code review, and more ownership than you've been trusted with before.
You'll fit if you
  • Are pursuing a degree in CS (or equivalent) and have built something real: a side project people actually used, open source contributions, a previous internship where you shipped.
  • Are comfortable in TypeScript, or good enough at programming that you'll be effective in it within a week.
  • Have played with LLMs beyond the chat box. Tool-calling, agent frameworks, React Flow, Yjs/CRDTs, or anything you hacked together at 2am are all table stakes.
  • Care about small details users never explicitly notice.
  • Are comfortable with uncertainty. We might implode tomorrow or we might grow 100,000,000% WoW next week.
  • Default to shipping. Let's get shit done.

What we offer
  • $8500 monthly salary
  • $2500 monthly stipend for housing
  • $70 per diem for meals
  • In-person in NYC with a lean team of people who love the game, obsessed with building the future of creativity.
