• Monitor production systems to ensure performance and reliability  

• Investigate, report, and resolve bugs and production issues  

• Participate in code reviews and maintain high engineering standards  

• Prepare and release application versions through CI/CD pipelines  

• Continuously improve systems by addressing technical debt and enhancements  

• Maintain and improve technical documentation  
  

AI-Enabled Engineering Responsibilities:

• Actively use AI tools (e.g. Claude, Copilot, generative AI) in day-to-day development  

• Leverage AI to accelerate coding, debugging, testing, and documentation  

• Critically evaluate and validate AI-generated outputs for correctness, security, and maintainability  

• Identify opportunities to automate repetitive engineering tasks using AI  

• Continuously improve personal and team productivity through better AI usage  

What We Are Looking For 

Core Engineering Skills:

• Strong experience building and maintaining RESTful APIs  

• Solid expertise in PHP (7 & 8) and frameworks (preferably Symfony)  

• Good understanding of OOP and software design principles  

• Experience with relational databases (e.g. MySQL)  

• Familiarity with Git, CI/CD, and Docker  

• Experience with automated testing (e.g. PHPUnit)  

• Ability to debug, profile, and optimise performance  

• Understanding of distributed systems and backend architecture  

• Familiarity with logging and monitoring tools (e.g. ELK/Kibana)  

• Exposure to Kubernetes or container orchestration  

• Understanding of Agile methodologies (Scrum, Kanban)  

AI Fluency & Mindset:

• Practical experience using AI tools in software development (e.g. code generation, debugging, workflow support)  

• Ability to critically assess and refine AI-generated code  

• Demonstrated use of AI to improve development speed and efficiency  

• Curiosity and willingness to experiment with new AI capabilities  

• Mindset of continuously improving how work is done using AI, not just adopting tools  

Ways of Working:

• Comfortable working in remote and multicultural teams  

• Strong problem-solving skills and ability to work independently  

• Clear communication skills in English (written and spoken)  

• Proactive mindset with a focus on outcomes and continuous improvement
