Full job description

At Mixam, we’re more than just a printing company, we’re the place where creativity meets cutting-edge technology. Headquartered in Watford, with offices in the UK, US, Canada, Australia, Europe, Philippines and Japan, we’re a fast-growing, privately held tech-forward print business founded in 2007, offering customisable, high-quality print services from zines and comic books to packaging, business cards and hardcover books for creators and brands across the globe.

Our mission? To make print easy, accessible and inspiring, whether that’s for authors wanting perfect-bound books or retailers seeking eco-conscious, tailored solutions. We combine advanced printing tech, user-friendly online tools, sustainable materials and exceptional service to help our customers bring their ideas to life swiftly and beautifully.

Join a team where your work matters, where collaboration and growth are part of the daily rhythm, and where you’ll play an active role in redefining & innovating print for the digital age.

About the role:

We’re looking for a Senior Frontend Developer to lead the development of modern, scalable web applications. You’ll play a key role in shaping frontend architecture, integrating with backend services, and delivering high-quality user experiences. This role suits someone who is comfortable working across the stack when needed and thrives in a fast-paced, agile environment.

Key Responsibilities:

Build and maintain high-quality, performant web applications using React, TypeScript, and modern JavaScript
Design and implement reusable, scalable frontend components and architecture
Integrate with REST APIs and backend services, ensuring robust data handling and error management
Collaborate closely with backend developers, designers, and product teams
Occasionally contribute to backend development (e.g., creating or extending APIs)
Manage multiple tasks and priorities in an agile, sprint-based workflow
Write clean, maintainable, and well-tested code
Participate in code reviews and contribute to best practices and technical standards

Requirements

Required Qualifications

Strong proficiency in React, TypeScript, and modern JavaScript (ES6+)
Solid understanding of frontend tools and workflows, including Node.js, npm, and Webpack
Experience integrating with and consuming RESTful APIs
Proficient in HTML5, CSS3, and responsive design best practices
Experience with styling frameworks such as Styled Components and/or Bootstrap 5
Strong problem-solving skills with keen attention to detail
Ability to manage multiple priorities and switch contexts effectively
Experience working in Agile/Scrum environments

Preferred Qualifications

Exposure to Java (Spring Boot) and backend API development
Full-stack mindset with the ability to contribute beyond the frontend when needed
Experience with performance optimisation and frontend architecture at scale
Experienced using git

Working Style

Self-driven and proactive
Comfortable balancing multiple priorities
Strong communicator who can collaborate across disciplines
Pragmatic approach to problem-solving and delivery

Benefits

Why Join Us?

This is your chance to be part of something new and exciting - helping to establish Mixam in Japan while being backed by an experienced, supportive international team. You’ll play a key role in shaping how we support our Japanese customers and, as the team grows, you’ll have the opportunity to grow with it. Make this section something tailored to the role.

Equality, Diversity & Inclusion:

At Mixam, diversity, equity and inclusion are at the heart of who we are, and we welcome applications from people of all backgrounds. We know few people meet every requirement, so if you’re excited about this role, we’d love to hear from you and we’ll consider your overall experience and potential. We’re also committed to minimising our environmental impact and creating a workplace where everyone feels valued and supported.

Mixam. The Smart Way to be Hired.
