Job description

We are partnering with a technology company building highly interactive performance-critical digital products where frontend engineering sits at the core of the product experience. This is a unique opportunity for engineers who enjoy solving technically demanding problems that go far beyond traditional frontend development. The product environment involves building real-time highly interactive systems where rendering performance, responsiveness, and seamless user interaction are fundamental requirements rather than secondary considerations.

This role is particularly well suited to engineers who have worked in performance-intensive environments such as gaming, simulation, immersive technology, or other systems where low latency and rendering efficiency directly impact product performance.

The Role

As a Senior Frontend Engineer, you will be responsible for building complex frontend systems powering highly interactive user experiences in a performance-critical environment. You will work on products where frontend architecture must support real-time responsiveness, sophisticated interaction models, advanced rendering workflows and consistently high-performance execution. This role requires engineers who are comfortable operating beyond standard web application development and have experience building systems where performance is a core engineering consideration.

Key Responsibilities

• Design and develop complex frontend systems supporting highly interactive product experiences.
• Build performant scalable interfaces where rendering speed and responsiveness directly impact product functionality.
• Develop real-time user interfaces that handle continuous state updates and event-driven interactions.
• Work with browser-based rendering technologies to build graphics-intensive frontend experiences.
• Optimize frontend architecture for low latency, performance, and efficient rendering pipelines.
• Collaborate closely with product, design, and engineering teams to build technically sophisticated interactive systems.
• Identify performance bottlenecks and continuously improve rendering and runtime efficiency.
• Contribute to architectural decisions around frontend performance, scalability, and system responsiveness.

Required Experience

• 7+ years of software engineering experience.
• Strong expertise in React and TypeScript.
• Experience building complex, highly interactive frontend applications.
• Experience working with Three.js, WebGL, or similar rendering technologies.
• Strong understanding of frontend performance optimization and browser rendering behaviour.
• Experience building low-latency, real-time interactive systems.
• Strong understanding of component architecture and scalable frontend engineering practices.
