The team you will join:

Mirakl is looking for a front-end developer to take ownership of the development and maintenance of our corporate website. This role sits at the intersection of engineering, design, and marketing.

Your impact:

  • You will build pages and components that are pixel-accurate, fast, accessible, and measurable, with a strong focus on user experience and conversion.

What you will bring to the role:

  • Own day-to-day development and maintenance of the corporate website, from implementation to continuous improvement.
  • Translate design into pixel-perfect, responsive, accessible interfaces, with strong attention to spacing, typography, and UI states.
  • Create and refine micro-interactions and motion to improve clarity, feedback, and usability.
  • Implement reusable components, templates, and content models that scale across pages and campaigns.
  • Work closely with Design and Marketing to deliver content and campaign needs quickly while maintaining high quality standards.
  • Ensure strong performance, SEO & GEO best practices, and reliable releases.
  • Set up and use tracking to understand performance (traffic, conversion, funnels) and propose improvements based on data.
  • Improve the integration workflow (QA, documentation, review process) to scale safely.
  • Contribute to HubSpot development needs, such as landing pages and marketing emails.

What Mirakl is looking for in a candidate:

  • Proven knowledge of modern front-end development with React/Tailwind, with deep CSS proficiency.
  • Front-end integration skills with a 'designer-level' eye for detail. You can deliver a pixel-perfect UI without compromising responsiveness and accessibility.
  • Solid UX sensitivity, and the ability to make practical trade-offs through code.
  • Proven experience implementing micro-interactions (hover states, transitions, loading states, motion, feedback).
  • Hands-on experience with headless CMS, and platforms such as Contentful, Prismic, Strapi (or similar).
  • We are looking for someone bilingual in English.

Good to Have:

  • Good understanding of website performance, SEO GEO basics, and analytics/tracking, with an interest in the business goals of corporate websites.
  • Knowledge of HubSpot (templates, landing pages, emails).
  • French skills are a plus.

What will make you successful in this role:

  • You are quality-driven, fast, and reliable.
  • You care about details (layout, typography, interactions, consistency) and you can explain your choices.
  • You collaborate well with designers and marketers, and you can turn feedback into concrete improvements.
  • You take ownership and can work independently while keeping stakeholders aligned.

The role is based in London Soho and offers a hybrid set up with at least 3 days a week working at the office.

Recruitment Process:

  • Interview with the Talent Acquisition Partner – 30-minute phone call
  • Interview with our Technical Leader – 45 minutes video call
  • Final Interview with the Manager (STAR method) – 45 minutes at the office
