Job Description

Smartbox is seeking an exceptional and passionate back-end Software Engineer to contribute to the success of their Dublin HQ IT team. If you're ready to take on a massive challenge in a company where you can make a significant impact, we want to hear from you. We are looking for a PHP Software Engineer with at least 4 years of experience to design, build, and maintain scalable backend systems. This role goes beyond traditional backend development. You will be expected to actively leverage AI tools and workflows to improve productivity, code quality, and delivery speed — and to continuously evolve how you work. You will contribute to core services, APIs, and integrations, while helping shape a more efficient, modern engineering approach within the team.

Job Responsibility

  • Design, build, and maintain scalable backend services and RESTful APIs
  • Write clean, maintainable, and well-tested code
  • Contribute to system design and distributed architecture
  • Maintain and evolve applications using modern PHP (7/8) and Symfony
  • 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
  • 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

Requirements

  • 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)
  • 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
  • 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
