Are you ready to push the boundaries of digital creativity and user experience? At Lab Digital, we're looking for a Senior Frontend Engineer who is passionate about crafting seamless, high-performance digital products. Dive into a role where your expertise in React and Next.js shapes the future of e-commerce and content websites.

about you & the role

At Lab Digital, we strive to make a positive impact by creating outstanding digital products for our clients, including global e-commerce platforms, content websites, and high-traffic middleware solutions.

Many of the products we develop use React in combination with Next.js. We apply a component library approach and develop in collaboration with UX and design teams. We have a strong focus on performance, both in consuming data from GraphQL services, and in generating the responses. A good user experience and excellent scores in web vitals / Lighthouse are essential for our field.

As our ideal candidate, you're not just skilled in coding - you're a visionary who understands the importance of collaborative development. Working alongside our UX and design teams, you'll bring digital concepts to life, ensuring every product resonates with its intended audience.

Our collaborative environment thrives on agile methodologies, with 2 to 3-week sprints involving multidisciplinary teams. As a Frontend Engineer, you will be responsible for delivering high quality software in collaboration with (UX) designers, QA specialists, business analysts, solution architects, a scrum master, and a project manager. For larger clients, you may find yourself working across multiple teams, fostering collaboration and knowledge sharing.

what you do

• Develop and maintain web applications using React and Next.js, focusing on performance and user experience.
• Implement component libraries in collaboration with UX/design teams, ensuring high web vitals and Lighthouse scores.
• Craft well-documented component libraries using tools like Storybook, emphasizing code reusability.
• Work within agile sprint cycles, delivering quality software alongside designers, QA specialists, business analysts, and more.
• Supporting teammates in their work and provide feedback in a well-structured manner.
• Engage in multiple projects, possibly across different teams, to drive innovation and collaboration.

what you bring

You will have a strong background in delivering high quality, reliable software solutions using modern software development techniques and working as part of a fully integrated team. We expect you to bring the following toolkit:

• At least 4 years of demonstrated experience in implementing production-level projects in JavaScript/TypeScript with a focus on React.
• Experience mentoring and supporting team members and guiding clients.
• Proven track record in front-end development, particularly in the e-commerce domain.
• Expertise in styling solutions (Styled Components, Emotion, CSS Modules, SCSS).
• Strong foundation in modern software practices (unit/integration testing, CI/CD pipelines).
• Familiarity with server-side rendering frameworks (Next.js, Gatsby, Remix.run).
• Knowledge of build tools (Webpack, ESBuild, Vite, SWC).
  • Experience supporting and mentoring junior software developers, and contributing to a productive team environment.
  • Excellent communication skills, both written and spoken (and thus able to deliver documentation and help with training, for example)
• Bonuspoints for:
  • Experience with GraphQL, Apollo Client, URQL.
  • Background in cloud applications (AWS/Azure) and Terraform.
  • Skills in animation frameworks (Framer Motion, GSAP).

We celebrate building diverse teams from all backgrounds. At the moment, we're only able to hire people already living in The Netherlands.
