Full Stack Software Engineer – AI & 3d Applications

Your role

This is a Full Stack Engineer role with a rich and varied technology stack. You will work across the full application layer, from building interactive browser-based 3D interfaces to designing robust backend services and APIs, while integrating AI capabilities through modern LLM frameworks and SDKs. The role sits at the intersection of applied AI engineering and real-time 3D visualization, leveraging technologies such as Three.js, WebGL, and LLM orchestration frameworks to build intelligent, geometry-aware applications. The successful candidate will have the opportunity to contribute meaningfully to applied AI research while working with a modern, diverse set of technologies at the forefront of the field.

The position holder will be required to perform the following tasks:

• Build browser-based 3D visualization experiences using libraries such as Three.js and WebGL to render and interact with complex geometric data
• Design intuitive, user-facing interfaces that effectively communicate research concepts and results to both technical and non-technical audiences
• Participate in the full software development lifecycle, from early-stage prototyping through to deployment and maintenance
• Engage with industrial partners to understand their requirements and help translate research into practical, deployable solutions

Your profile

• Bachelor’s or Master’s degree in Computer Science, Software Engineering, or a related field
• Experience with Three.js and WebGL, including scene management, geometry interaction, camera controls, and rendering optimization for complex 3D models
• Experience with LLM orchestration frameworks, e.g. Lang Chain, LlamaIndex, and LLM APIs, e.g. OpenAI, Anthropic, including context engineering and API integration for building production-grade AI-powered features
• Experience with Python and at least one server-side web framework such as Flask or FastAPI, including building and maintaining REST APIs
• Comfortable with modern DevOps practices including Git, Docker, and CI/CD pipelines
• Nice to have: Familiarity with CAD Kernels like Open CASCADE, or experience with 3D modelling, CAD design software, or 3D printing workflows
• Fluent written and spoken English is required
