About You
You’re the kind of developer who gets unreasonably excited about shaving milliseconds off a query, finding the root cause of a bug before your coffee gets cold, and turning complex backend challenges into elegant solutions. APIs, databases, caching layers, and scalable architecture are your playground. You believe clean code is a love language, technical debt should be kept on a short leash, and “it works on my machine” is not a deployment strategy. Whether you're optimising performance, architecting new services, or diving into a production issue, you thrive on building systems that are fast, reliable, and ready for whatever a million bargain-hunting customers throw at them.
Responsibilities:
Develop and maintain high-performance, scalable backend systems using PHP, Laravel and related technologies.
Design, build, and optimize GraphQL APIs and other backend services.
Optimize application performance, database queries, and caching strategies for speed and scalability.
Ensure the security and integrity of the backend infrastructure, implementing best practices for authentication, authorization, and data protection.
Write clean, maintainable, and well-documented code.
Implement automated testing, debugging, and deployment strategies to ensure software reliability.
Stay up-to-date with industry best practices and emerging backend technologies.
Work closely with product owners and stakeholders to gather requirements and define project scope.
Troubleshoot and resolve technical issues in a timely manner.
Continuously improve the architecture, codebase, and development processes to enhance overall efficiency and maintainability.
Experience and Qualifications:
BSc Computer Science, BEng, or equivalent qualification. However, your ability to demonstrate deep backend development expertise will trump a formal qualification.
At least 5 years of experience in backend development, with a strong focus on PHP and Laravel (or a similar framework).
Solid understanding of API (RESTful, GraphQL) design and best practices.
Strong proficiency in SQL databases (MySQL/PostgreSQL) and experience with database optimization techniques.
Strong knowledge of Docker and CI/CD pipelines.
Proficiency in version control systems (Git) and collaborative development workflows.
Familiarity with Redis is a plus.
Experience with cloud-based architectures (Azure, Google Cloud or AWS) and microservices is advantageous.
Strong debugging, troubleshooting, and performance optimization skills.
Passion for writing clean, well-structured, and efficient code.
Strong problem-solving and analytical thinking abilities.
Ability to work both independently and collaboratively in a team environment.
