Full Stack Engineer (Real-Time / Interactive Systems)

What we're looking for
We’re looking for a Full Stack Engineer who enjoys building real-time, interactive systems that
go beyond traditional web applications.
This is not a typical CRUD-focused role. You’ll be working on a product that combines rendering, input systems, video, and backend services into a single performance-sensitive
experience.

You should be comfortable operating in a fast-moving startup environment where requirements evolve quickly. We value engineers who take ownership, think creatively, and are comfortable
solving problems without fully defined specifications.

Who we are
we are venture-backed startup building patented technology that enables anyone to turn video into interactive games instantly, with no code.
We are creating a new category of interactive gaming content, combining real-time rendering, video, and game mechanics across mobile and web.

What you'll do You’ll work across the full stack, building both frontend interactive systems and backend
services that power them.
You’ll be responsible for optimizing the browser-side rendering and interaction layer, working with the DOM, Canvas 2D, WebGL, and browser APIs, and interfacing with our WebAssembly-based game engine.

On the backend and platform side:
● Design and build scalable Node.js services and APIs
● Model and manage data in MongoDB for real-time and user-generated content systems
● Develop systems that support gameplay state, media, and interactive features
● Ensure reliable communication between frontend systems and backend services
● Contribute to system architecture, performance optimization, and scalability decisions

On the frontend and rendering side:
● Collaborate with cross-platform engineers to integrate our WebAssembly-based game
engine into the browser environment
● Build video playback integrations that synchronize tightly with a real-time game loop
● Implement input handling systems such as touch, pointer events, and device orientation
with low-latency feedback
● Optimizing a high-performance rendering pipeline using Canvas 2D and WebGL to
achieve consistent performance and smooth frame rates on mobile browsers

Across the stack:
● Write unit, integration, and browser-based tests to ensure reliability
● Contribute to technical documentation and internal tooling
● Work closely with product, design, and engineering teams to ship features end-to-end

Core requirements
● Strong experience with Node.js, React, and MongoDB
● Solid JavaScript or TypeScript fundamentals
● Understanding of browser performance, including render loops, repaint behavior,
memory usage, and input latency

Nice to have
● Experience with Kotlin Multiplatform and WebAssembly
● Experience with Canvas 2D and WebGL in production or advanced projects
● Experience with game development or real-time interactive systems
● Experience with graphics, animation systems, or media-heavy applications
