Role Description

We are looking for an experienced, hands-on Senior Developer to support the migration of an enterprise digital platform from Sitecore to Contentful. The role involves both content migration and the migration of existing applications, React/Typescript development, API integrations and modern headless architectures. We are also looking for someone with an AI-first mindset who embraces AI-assisted and spec-driven development to improve delivery speed, quality and consistency, while retaining ownership of technical judgement and code quality.

Key Responsibilities

• Application and Content Migration
  • Migrate and modernise existing Sitecore-backed applications to work with Contentful.
  • Develop, refactor and enhance frontend applications using React and TypeScript.
  • Replace Sitecore-specific dependencies, components and integrations with Contentful-compatible solutions.
  • Develop content migration tooling, scripts and automated transformation processes.
  • Implement Contentful content models, API integrations and content delivery patterns.
  • Ensure migrated applications maintain functionality, performance, accessibility and quality.
• AI-Native Engineering
  • Adopt an AI-first mindset, proactively identifying opportunities to accelerate development, migration and problem-solving using AI.
  • Apply spec-driven development, using clear technical specifications, acceptance criteria and tests to guide AI-assisted implementation.
  • Leverage AI to support Sitecore analysis, schema mapping, migration script generation, application refactoring and validation.
  • Use AI coding assistants effectively while reviewing, testing and taking accountability for generated outputs.
  • Share AI-enabled development practices and contribute to improving team productivity.
• Engineering Quality and Collaboration
  • Independently own complex development tasks and significant migration components.
  • Write clean, maintainable, well-tested code and contribute to CI/CD and automated testing.
  • Identify technical risks, dependencies and opportunities for improvement.
  • Collaborate with Lead Developers, architects, QA and content teams.
  • Support less experienced developers through mentoring, code reviews and knowledge sharing.

Qualifications

• Strong commercial software engineering experience, particularly with React and TypeScript.
• Experience migrating, modernising or refactoring existing frontend applications.
• Practical experience with headless CMS platforms, preferably Contentful, and an understanding of Sitecore.
• Strong understanding of APIs, integration patterns and content modelling.
• Experience with backend development, migration scripting or data transformation.
• Practical experience using AI-assisted development tools and an understanding of spec-driven development approaches.
• Experience with automated testing, CI/CD and modern engineering practices.
• Ability to work independently, solve complex problems and influence technical implementation decisions.

Desirable Experience

• Direct experience migrating Sitecore applications and content to Contentful.
• Experience with Next.js, Sitecore JSS or CMS/DXP replatforming.
• Experience applying AI to content analysis, migration automation, code transformation or test generation.
• Experience with multilingual, multisite or composable digital platforms.

Benefits

• Private health insurance.
• Education program with training and certification.
• Wellbeing program for a healthy and well-balanced life.
• Free beverages including coffee, drinks, and snacks at work.
