Frontend Developer (React)

About hubQuest

hubQuest brings together IT and analytics experts to build technology teams from scratch and strengthen existing teams for its partners. We help organisations develop solutions that support their transformation and create meaningful impact.

About the role

We’re looking for a solid mid-level Frontend Developer with strong React experience to join the team developing an AI Virtual Assistant for a global organisation operating across the food, beverage, fragrance, health and bioscience sectors.

The application supports people working in manufacturing sites. It initially developed as an additional interface for an existing platform used for processes such as document management and incident reporting. It is now evolving into a broader product supporting everyday factory operations and the needs of site teams and leadership.

We have a substantial roadmap of new features to build and roll out. You’ll help turn complex operational processes into clear, intuitive interfaces, working closely with the UX Designer, Product Owner and other developers.

What you’ll work on

The upcoming scope includes

• Safety and quality workflows.
• Audits, audit results and follow-up actions.
• Dashboards presenting operational information.
• Tier meetings supporting coordination and performance reviews at different organisational levels, from shop-floor teams to leadership.

Future plans include integrations with machine-monitoring applications and AI capabilities that help people access knowledge and understand what is happening across manufacturing sites.

These are future development directions, with the immediate focus on building and delivering the product’s expanding operational capabilities.

The team and technology

The team currently includes a Product Owner, a Lead Developer, two AI Developers and a Software Developer. We’re expanding it with a UX Designer, a Backend Developer and this Frontend Developer role.

The frontend is built with React. The backend uses Node.js, TypeScript and NestJS. Your focus will be frontend development, with close collaboration on API integration and feature delivery.

What you’ll do

• Build and extend React interfaces for new and existing features.
• Translate UX designs and business requirements into usable, responsive application flows.
• Develop reusable components and maintain a consistent user experience across the product.
• Integrate frontend features with backend APIs, handling loading, error and empty states.
• Work with the UX Designer and Product Owner to clarify requirements, discuss implementation options and resolve edge cases.
• Collaborate with backend and AI developers to deliver complete features.
• Write maintainable code, participate in code reviews and contribute to appropriate testing.
• Investigate bugs, address performance issues and improve existing functionality.
• Take ownership of assigned features, communicate progress and raise risks or dependencies early.
• Participate in daily stand-ups and two-week sprints.

What we’re looking for

• Strong commercial experience with React and the ability to deliver production features independently at a solid mid-level.
• Good knowledge of JavaScript, TypeScript, HTML and CSS.
• Practical experience with component-based development, React hooks and application state management.
• Experience integrating applications with APIs and handling asynchronous data.
• The ability to build responsive, accessible interfaces and translate designs into working software.
• A practical approach to code quality, testing, debugging and maintainability.
• Confidence working with evolving requirements and discussing technical choices with the team.
• Strong communication skills and a collaborative approach.
• Very good spoken and written English for everyday work in an international environment.

Nice to have

• Experience with AWS.
• Practical experience using Claude to support software development, with careful review and validation of generated code.
• Familiarity with Material Design principles.
• Experience building internal business applications, dashboards or tools supporting manufacturing, safety, quality or audit processes.

What we offer

• A full-time B2B engagement.
• A fixed-term contract through 30 June 2027, with the possibility of an extension through 31 December 2027. The extension is not guaranteed.
• The opportunity to contribute to a growing product with a substantial roadmap and direct relevance to everyday manufacturing operations.
• Close collaboration with the Product Owner, UX Designer and development team.
• An international working environment and a Scrum-inspired approach, with daily stand-ups and two-week sprints.
• A friendly, non-corporate environment, flexible working arrangements, private medical care and a Multisport card.
