Frontend Engineer (Mid-Level)

Who is Parser? Technology alone does not create impact - the right teams do. Founded in 2018, Parser is a boutique technology services and consulting firm helping global organisations solve complex business challenges through digital transformation, product development and AI & data, delivered by teams that combine strong technical depth with a consulting mindset.

We combine global reach with a mindset focused on agility, senior expertise, and close collaboration. We work as an extension of our clients' teams, helping them define the right problems, shape solutions, and deliver technology-driven outcomes that create measurable business value.

Our expertise spans software engineering, AI & data, product development, and customer experience, delivered by teams that combine strong technical depth with a consulting mindset.

Why Join Us?

If you are looking for a place where you can think beyond execution, take true ownership of outcomes, influence decisions, and continuously learn alongside top-tier specialists in a truly global environment, we'd love to meet you.

How will you impact?

As a Mid-Level Frontend Engineer, you will own consumer-facing web features end-to-end within a microfrontend ecosystem. Your work directly drives organic acquisition and user experience through web performance optimisations, seamless right-to-left localisation, and reliable product delivery.

Your key responsibilities

• Build and ship responsive, mobile-first user interfaces using React, TypeScript, and Next.js across server- and client-rendered applications.
• Develop reusable design system components supporting multi-country configuration, internationalisation, and right-to-left (RTL) Arabic layouts.
• Optimize web performance and Core Web Vitals, including bundle size, hydration costs, rendering paths, image/font loading, and caching strategies.
• Maintain robust application contracts and shared libraries across microfrontend architectures.
• Implement reliable analytics tracking, feature flags, and unit, component, and end-to-end testing (using Playwright and Storybook).
• Utilise production signals, real-user monitoring, and error tracking tools to proactively resolve performance and user-facing issues.
• Collaborate closely with product, design, SEO, and backend teams, delivering thoughtful code reviews and engineering improvements.

What you'll bring to the role

Essential Requirements

• 3+ years of professional frontend engineering experience delivering and operating production web applications.
• Strong proficiency in React, TypeScript, and modern state/data-fetching patterns.
• Hands-on experience with Next.js (SSR/SSG, routing, server vs. client-side execution).
• Solid foundation in semantic HTML, CSS Modules/responsive layout systems, and web accessibility fundamentals.
• Practical experience with API integration, unit/component testing, and automated E2E testing (Playwright preferred).
• Proven understanding of Core Web Vitals, web performance measurement, and debugging techniques.

Desirable Requirements

• Experience with microfrontend architectures, monorepos, or shared npm packages.
• Hands-on experience with internationalisation (i18n), right-to-left (RTL) layouts, and SEO-driven products.
• Exposure to frontend observability, tag management, feature flagging, or geospatial/maps APIs.

Location: Spain (Remote). Candidates must be able to accommodate UAE working hours.

You will receive

• The chance to join an organization with triple-digit growth that is changing the paradigm on how software products are built.
• The opportunity to be part of an amazing, multicultural community of tech experts.
• A highly competitive compensation package.
• A flexible and hybrid working environment.
• Medical insurance.
