Senior Front-End Developer

Role Overview

We’re looking for a Senior Front-End Developer to take a leading role in building and evolving our e-commerce platform. You’ll work within a small, fast-paced team delivering high-quality user experiences across web and mobile, collaborating closely with designers, backend engineers and stakeholders.

This is a hands‑on role where you’ll shape the technical direction of our frontend, contribute to architecture decisions and mentor other developers — all while shipping production‑ready features that directly drive business growth.

What You’ll Do

• Lead the development of our e‑commerce platform using modern JavaScript frameworks, HTML and CSS.
• Design, develop and deploy scalable, high‑performing and maintainable frontend solutions.
• Work closely with cross‑functional teams — including designers, stakeholders and backend engineers — to build seamless and intuitive user experiences.
• Help shape the technical vision and strategy of the engineering team.
• Write clean, efficient and well‑documented code following modern best practices and design patterns.
• Build and maintain developer tooling, deployment pipelines and infrastructure to support smooth delivery.
• Contribute to improving team processes and mentor junior developers through code reviews and knowledge sharing.
• Deliver features that enhance the experience for both our customers and internal merchandising teams.

Required

What We’re Looking For

• 5+ years of professional experience in JavaScript development with modern frameworks and technologies.
• 3+ years of hands‑on experience with React and Next.js, delivering production‑ready code.
• Strong proficiency in TypeScript, HTML5, CSS3 and responsive web development.
• A sharp eye for detail with the ability to create pixel‑perfect, responsive layouts across devices.
• In‑depth understanding of the full web development lifecycle from design to deployment.
• Experience with REST and GraphQL APIs and building non‑blocking, asynchronous web applications.
• Proven track record of shipping production‑ready software at scale, with experience in both manual and automated testing.
• Experience meeting or exceeding Google PageSpeed performance guidelines.
• Strong communication skills with the ability to work effectively with both technical and non‑technical stakeholders.

Nice to Have

• Experience as a full‑stack developer.
• Hands‑on experience deploying to cloud platforms such as AWS, GCP or Azure.
• Professional experience working with headless CMS platforms and web application frameworks.
• Knowledge of SEO principles and web performance optimisation.
• Experience with containerisation and CI/CD pipelines.
• Contributions to open‑source projects or participation in developer communities.

Behaviours & Traits

• Commercially wired – you think in LTV, contribution margin, and payback periods, not just campaign metrics
• Ownership mindset – you don’t wait to be told; you identify the gap and go close it
• Comfortable with ambiguity – the playbook doesn’t fully exist yet; you’ll write it
• Bias for testing – you run experiments, read the data, and act on it quickly
• Customer‑obsessed without being soft – you understand what makes Protein Works’ community tick and you use that commercially
