## 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.

If this is the kind of problem you’re interested in, apply!

## About Melius

## Company Overview
- **One-liner**: Melius is a visual canvas and platform where creative professionals and AI agents collaborate to generate, iterate, and compose images, video, audio, and text.
- **Entity Type**: Private (Seed stage)
- **Headquarters**: New York, United States
- **Founded**: 2025
- **Founders**: Arnav Ramu (Co-Founder & CEO), Young Kim (Co-Founder), Joowon Kim (Co-Founder)

## Core Business
- **Primary industry/industries**: Creative Software, AI Agents, Media & Entertainment
- **Target customers**: Creative professionals (marketers, designers, filmmakers, content creators), agencies, e-commerce teams, and GTM/growth teams.
- **Mission or purpose statement**: "The creative canvas where humans and agents create together." The company aims to let users act as creative directors while AI agents handle execution, eliminating the need for prompt engineering.

## Products & Services
- **Melius Canvas**: An infinite, multiplayer canvas where users arrange "nodes" (text, image, video, file, group) and wire them together with "edges" to compose multi-step generative workflows. Every prompt is exposed, and every output is editable.
- **Agent "Mel"**: A built-in AI agent that users brief in natural language. Mel handles model selection, prompt writing, and workflow assembly across multiple models.
- **Supported Models**: Integrates with GPT, Claude, Gemini, Grok, Flux, Seedream, Nano Banana, Veo, Sora, Kling, Seedance, ElevenLabs, and more.
- **Magic Resize**: A feature to take one winning asset and automatically reformat it for every platform.

## Market Standing
- **Valuation/Market Cap**: Not publicly available
- **Key Metric**: Revenue-generating (founders have stated "we have revenue" on LinkedIn); currently in Seed stage per F4 Fund.
- **Notable Investors/Partners**: Backed by F4 Fund (a seed-stage venture firm focused on media & entertainment). Partnering with Contra for a $10,000 challenge.
- **Growth Signals**: Very early stage with massive momentum. LinkedIn shows a 42.9% monthly headcount growth (4 employees as of mid-2026). Website traffic grew +1,827.3% month-over-month. Actively hiring founding engineers and founding GTM roles.

## Competitive Advantages
- **Agent-First Canvas**: Unlike single-model tools, Melius provides a tunable, multimodal node-based canvas where users can inject their taste at any step in the workflow.
- **Multiplayer & Agent Collaboration**: Built for real-time collaboration between humans and AI agents, not just human teams.
- **Model Agnosticism**: Access to all major image, video, audio, and language models from one interface, letting users pick the best tool for each task without switching platforms.
- **No Prompt Engineering**: The "Mel" agent abstracts away prompt engineering, letting users focus on creative direction.

## Strategic Focus
- **Product Velocity**: Rapidly shipping new features and model integrations (e.g., GPT Image 2, Happy Horse 1.0, Veo 3.1, Magic Resize).
- **Community & Talent**: Running challenges (e.g., Contra partnership) to attract creative developers and build a community. Aggressively hiring to scale the small team.
- **Vertical Expansion**: Targeting specific use cases (e-commerce product shots, agency concept work, GTM campaign creative) while staying platform-agnostic.

## Why Work Here
- **Culture**: A high-agency, fast-shipping startup environment. The team is tiny (4 people) but growing, meaning early employees will have outsized impact on product and culture.
- **Remote/Hybrid/Office**: Based in New York, NY. Hiring for NYC-based roles (founding engineers, founding GTM).
- **Notable Perks**: Founders are offering a $25,000 referral bonus for new hires. The company has revenue and ships "incredibly quickly." Working directly with the co-founders (ex-Scale AI, ex-Nike, ex-Google, ex-Snowflake talent pool).
- **Engineering Culture**: Building a creative canvas that integrates with cutting-edge AI models. The tech stack includes Brex and Ramp. Ideal for engineers who love creative tools, AI, and fast iteration.
