We're looking for a Senior Front End Developer to play a key role in building the user interface for our Multimodal Analysis Framework (MAF).

Design and develop a modern, responsive user interface using React.
Build new application features that enable users to upload, manage and analyse media assets.
Create intuitive dashboards and visualisations for media processing results, with a particular focus on video-based workflows.
Develop Backend-for-Frontend (BFF) services using Node.js to support the React application.
Integrate with existing APIs and backend services.
Deploy and maintain applications using Docker and Kubernetes.
Work closely with Product Managers, Designers and Backend Engineers to deliver high-quality solutions.
Participate in code reviews, testing and continuous improvement initiatives.
Contribute to technical decisions, application architecture and engineering best practices.
What We're Looking For
Essential Skills
5-8 years of professional software development experience.
Strong commercial experience building modern applications with React.
Excellent JavaScript and/or TypeScript skills.
Experience developing Node.js services or Backend-for-Frontend applications.
Experience consuming REST APIs and integrating frontend applications with backend services.
Hands-on experience with Docker and Kubernetes.
Experience working with Redux or similar state management libraries.
Familiarity with PostgreSQL and cloud object storage such as Amazon S3.
Strong problem-solving skills and the ability to work independently within a collaborative team.
Nice to Have
Experience with Golang.
Experience working on API platforms or microservices.
Experience building applications involving video processing, media workflows or data visualisation.
Exposure to cloud-native environments and distributed systems.
Why Join?
Help build a brand-new platform from the ground up.
Join a small engineering team where your work will have immediate impact.
Work on innovative technology that processes and visualises video, image and document assets.
Collaborate closely with experienced engineers and product teams in a fast-paced, agile environment.
Opportunity to influence technical direction and shape the future of the platform.
