Senior PHP Backend Developer at OneDayOnly

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.
