Senior Pixi.js Developer

About Digis
Digis is a European IT company with 200+ professionals delivering high-quality software solutions for clients worldwide. We partner with well-known global companies, helping them scale their products with strong engineering teams.
 

About the Project
We are developing a next-generation collaborative drawing and visualization tool used in high-performance, real-time environments. The product enables teams to design, visualize, and collaborate on complex projects in real time, similar in nature to Figma, but tailored for demanding professional use cases.

The project is currently in the active development stage with long-term plans for scaling and stabilization. You will join a skilled, distributed team of backend, frontend, and QA engineers, and will work closely with the Product Owner and a PixiJS expert already on the team.
 

Responsibilities

• Develop advanced 2D drawing/visualization features in PixiJS (plots, stage diagrams, layers, etc.).
• Build smooth drag-and-drop interaction for shapes on canvas.
• Enable real-time multi-user collaboration (multiple cursors, CRDT sync).
• Optimize rendering performance for large object sets while keeping the experience smooth.
• Integrate backend data with WebSocket connections.
• Improve editor UX (toolbars, snapping, grids, layers).
• Collaborate with the team to split APIs into multiple microservices and emulate cloud locally.
