We're working with Datatech on this exciting opportunity.

Join a dynamic UK adventure business as they bring their web development in-house and revolutionize internal systems. This hands-on role offers the chance to make a real impact, evolving a high-performance customer-facing website and building innovative internal tools, all within a small, trusted tech team.

The Role

  • Evolve and maintain a modern, high-performance website, focusing on features, accessibility, and SEO fundamentals.
  • Build and integrate internal tools using Node.js or similar to replace legacy Power Apps and streamline workflows.
  • Own the full development lifecycle from discovery to release and iteration, ensuring practical solutions.
  • Collaborate closely with marketing and operational stakeholders to deliver impactful digital solutions.

What You'll Need

  • Proven commercial software development experience in web and/or internal systems.
  • Strong proficiency in JavaScript and TypeScript fundamentals.
  • Experience with front-end frameworks like Astro, Gatsby, or Next.js for component-based UI and responsive design.
  • Familiarity with back-end API development (Node.js) and workflow-driven methodologies.
  • A practical, adaptable mindset with excellent communication and collaborative instincts.

What's On Offer

  • The opportunity to work remotely within a supportive and innovative environment.
  • A chance to significantly impact both customer-facing platforms and internal operations.
  • Engaging, scenario-led interviews focused on your problem-solving abilities, not lengthy take-home tasks.
  • Work with a modern tech stack, including Git and AI-assisted development tools.
