Reference: 1234_1784059398

Senior Front End Developer (React)

Location: Washington, DC (3 days onsite)
Experience: 5-8 Years

About the Role

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).

Our engineering team has developed a powerful API platform that processes media assets such as videos, PDFs, and images. We're now building a modern web application that allows customers to easily upload content, manage processing jobs, and visualize results through an intuitive user experience.

This is a unique opportunity to help build an entirely new UI from the ground up, working within a small, highly collaborative engineering team where you'll have significant ownership and influence over the product.

What You'll Be Doing

  • 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.

GCS is acting as an Employment Business in relation to this vacancy.
