[Hiring] Senior Frontend Software Engineer @Shopfully

Role Description

We are looking for a Senior Frontend Engineer to join our team, focusing on building high-performance frontend applications that power our large-scale consumer platforms. You’ll be a key architect in our ecosystem, balancing the need for rapid feature delivery with the technical rigor required to maintain blazing-fast user experiences.

We are looking for a senior contributor who doesn't just write code but drives architectural decisions, optimizes for performance, and actively mentors fellow engineers. If you are passionate about the intersection of performance, user experience, and AI-driven innovation, this role is for you!

What You Will Do

• Build and evolve high-performance frontend features on our consumer-facing web platforms, with a strong focus on Core Web Vitals and SEO best practices that directly impact organic audience growth.
• Own frontend architecture decisions within a cross-functional team (product, design, backend devs), ensuring code quality, scalability, and measurable performance improvements.
• Drive technical SEO initiatives, from rendering strategy and structured data to crawlability and page speed, collaborating closely with SEO and product stakeholders.
• Explore and develop new content and engagement channels aimed at deepening user engagement with our platforms.
• Analyse frontend performance using real-user metrics and synthetic tooling, identifying bottlenecks and leading the resolution with a data-driven approach.
• Mentor junior and mid-level engineers, fostering a culture of quality, ownership, and continuous improvement.
• Integrate AI-assisted development practices (e.g. Claude Code) into day-to-day workflows and contribute to AI-powered product features that shape how millions of shoppers interact with our platforms.
• Partner with the Engineering Manager to support healthy team dynamics and contribute to a culture where people do their best work.

Qualifications

• Strong, hands-on experience with Next.js, React, and TypeScript.
• Deep understanding of Core Web Vitals and a track record of analyzing and improving frontend performance at scale.
• Solid knowledge of Node.js and how it integrates with frontend services.
• Familiarity with AI tools in your development workflow (e.g., Claude Code, Cursor, or similar).
• You think about the user journey and business impact, not just the technical implementation.
• Experience working in a cross-functional, international environment.
• A passion for supporting the growth of junior and mid-level developers.
• Fluent in English.

Nice to Have

• Experience with AWS and cloud-based infrastructure.
• DevOps knowledge: Comfort working with GitHub pipelines and AWS services.
• Familiarity with Tailwind CSS.
• Experience with Playwright for automated testing.

Salary Range

€50,000 – €70,000 fixed gross salary per year.
