About the Role

We're looking for a creative Interactive Systems Developer with a passion for building real-time, engaging applications that merge game design, robotics, and front-end development.

In this role, you'll design intuitive tools and interfaces that power next-generation robotic systems for use in healthcare. Your work will help make complex procedures more accessible to surgeons worldwide, thereby improving outcomes for patients.

This is a rare opportunity to join an early-stage robotics startup tackling one of the most impactful challenges in medicine: building intelligent systems that transform how surgery is performed.

What You'll Do

• Build interactive applications for robotics control, real-time visualisation, and simulation
• Design and implement 3D visualisations using tools like Three.js, Unity, Unreal Engine, and Babylon.js
• Create intuitive robotic control methods optimised for touchscreen and mobile devices
• Collaborate with hardware and software teams to integrate sensor data, control systems, and user input
• Develop performant and responsive web apps (TypeScript, React, Lit) and mobile apps (React Native, Ionic, SwiftUI)
• Prototype and iterate quickly on new ideas blending gaming, robotics, and UX
• Ensure accessibility, usability, and performance across all products

What You Bring

• Experience in game development or interactive 3D applications (Unity, Unreal Engine, or similar)
• Strong knowledge of TypeScript and modern front-end frameworks (React, Vue, Lit, Web Components)
• Familiarity with 2D/3D rendering libraries (Three.js, Babylon.js, Godot, Pixi.js)
• Understanding of real-time systems (WebSockets, streaming data, etc.)
• Strong UX instincts and attention to detail
• A collaborative mindset and comfort working across disciplines

Bonus Skills

• Experience with ROS (Robot Operating System), Gazebo, or RViz
• Familiarity with physics engines (PhysX, Bullet, Box2D)
• 3D modelling experience
• Mobile platform experience (React Native, Flutter)
• Background in accessibility or inclusive interface design
