About the Role

As a Senior PHP/Symfony Engineer, you will take hands-on ownership of backend development within a mature Symfony platform that manages marketing and revenue data for enterprise customers. The core application currently runs on Symfony 6.1, with an upgrade to Symfony 7 planned, alongside an Angular front end and TypeScript and Python AI agent microservices.

You will work within a remote, cross-functional product squad alongside engineering, product, QA and DevOps colleagues.

Responsibilities

  • Own and deliver backend work in the core Symfony application, working fully independently within 2–3 months of starting.
  • Critically assess code produced by the team and by AI tools, challenging proposed solutions and ensuring important aspects have been properly thought through.
  • Help move the application from Symfony 6.1 to Symfony 7, resolving versioning and legacy issues currently blocking the upgrade.
  • Improve application performance, scalability and maintainability so new features are easier and safer to add.
  • Work with the Angular front end, TypeScript and Python AI agent services, and the DevOps team where backend changes cross those boundaries. 
  • Read and reason about the Angular/TypeScript codebase despite the role being strongly backend weighted; strong front-end development skills are not required.
  • Understand how decisions affect the wider system, including Symfony, Angular and AI services, while identifying detail gaps in code and AI-generated output.
  • Challenge solutions, identify root causes and improve how things are built rather than simply completing tickets.
  • Deliver well-reasoned, maintainable solutions within a legacy codebase while maintaining a steady delivery pace.
  • Work with high autonomy and accountability while collaborating effectively within a remote, cross-functional squad.
  • Respect SOC 2, PII and security controls without exception.

    Requirements

  • 8+ years of commercial software engineering experience, including 5+ years in PHP. 
  • 7+ years of PHP experience at Expert level.
  • 3+ years of recent commercial Symfony 6.x/7 experience at Advanced level. Very senior Laravel experience that is clearly transferable may be considered, provided you have a solid understanding of how Laravel and Symfony differ.
  • 4+ years of Advanced experience in backend system design and scalability.
  • 2+ years of Advanced experience critically using AI tooling, including reviewing and challenging AI-generated output rather than accepting it blindly.
  • 5+ years of Advanced MySQL experience covering schema design and query optimisation. PostgreSQL or another relational database at the same depth may be considered.
  • 1+ year of Angular/TypeScript awareness. React or Vue with TypeScript may be considered, but zero front-end exposure is disqualifying.
  • 3+ years of Advanced automated testing experience with PHPUnit. Pest or equivalent PHP testing frameworks may be considered.
  • 1+ year of Intermediate experience with framework upgrades and legacy-code modernisation. Major version upgrades or refactoring in other large PHP codebases may be considered.
  • 2+ years of Intermediate AWS experience. Azure or GCP may be considered. 
  • Fluent written and spoken English. 
  • Strong written and verbal communication and a proven record of working effectively remotely.
  • Ability to work UK hours.
  • Ability to pass strict background checks and comply with PII policies.
  • Strong self-sufficiency, with the ability to work with zero handholding after 2–3 months while continuing to collaborate effectively.
  • A hands-on technical approach with an architect mindset: understanding how and why the system works rather than only producing code.

    •  

    Nice to Have

  • 2+ years of Intermediate CI/CD experience with GitHub Actions; GitLab CI, Jenkins or Azure DevOps are suitable alternatives.
  • Basic experience with Amazon Redshift or data warehousing; Snowflake or BigQuery may be considered. 
  • Azure exposure alongside AWS.
  • Previous project leadership experience.
  • Previous mentoring and technical leadership experience with other engineers.
