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.

This is a strongly backend-weighted, senior hands-on engineering role requiring an architect mindset, strong independence and the ability to understand how technical decisions affect the wider system. You will work within a remote, cross-functional product squad alongside engineering, product, QA and DevOps colleagues.

Responsibilities

• Take ownership of backend development within the core Symfony application, becoming fully independent in delivering work within 2–3 months of joining.

• Review and critically assess code written by the team and AI tools, challenging proposed approaches and making sure key considerations have been properly addressed.

• Support the migration from Symfony 6.1 to Symfony 7 by resolving versioning, compatibility and legacy issues currently preventing the upgrade.

• Improve the application’s performance, scalability and maintainability, making it easier and safer to introduce new functionality.

• Work across the Angular front end, TypeScript and Python-based AI agent services, collaborating with DevOps where backend changes impact other areas of the system.

• Be comfortable reading and understanding the Angular/TypeScript codebase, even though the role is primarily backend focused. Strong front-end development experience is not required.

• Understand the wider impact of technical decisions across Symfony, Angular and AI services, while spotting gaps or issues in both human-written and AI-generated code.

• Question existing approaches, identify root causes and look for better ways of building things rather than simply completing assigned tickets.

• Deliver thoughtful, maintainable solutions within a legacy codebase while maintaining a consistent pace of delivery.

• Work with a high level of autonomy and ownership while collaborating effectively with a remote, cross-functional team.

• Follow SOC 2, PII and security requirements consistently and without exception.

Requirements

• 8+ years of commercial software engineering experience, including at least 5 years working with PHP.

• 7+ years of Expert-level PHP development experience.

• 3+ years of recent commercial experience with Symfony 6.x/7 at Advanced level. Strong senior-level Laravel experience may be considered where the experience is clearly transferable and the candidate has a good understanding of the differences between Laravel and Symfony.

• 4+ years of Advanced experience in backend architecture, system design and scalability.

• 2+ years of Advanced experience using AI development tools critically, including reviewing, validating and challenging AI-generated code rather than accepting it without question.

• 5+ years of Advanced MySQL experience, including database schema design and query optimisation. Equivalent depth of experience with PostgreSQL or another relational database may also be considered.

• At least 1 year of experience working with or understanding Angular/TypeScript. Experience with React or Vue using TypeScript may also be considered, but some front-end exposure is essential.

• 3+ years of Advanced experience with automated testing using PHPUnit. Experience with Pest or another equivalent PHP testing framework may also be considered.

• At least 1 year of Intermediate experience working on framework upgrades and modernising legacy codebases. Experience with major-version upgrades or significant refactoring in other large PHP applications may be considered.

• 2+ years of Intermediate AWS experience. Equivalent experience with Azure or GCP may also be considered.

• Fluent written and spoken English.

• Strong written and verbal communication skills, with a demonstrated ability to work effectively in a remote environment.

• Ability to work UK hours.

• Ability to successfully complete strict background checks and adhere to PII and data protection requirements.

• Strong self-sufficiency, with the ability to operate independently and without handholding after 2–3 months, while continuing to collaborate effectively with the wider team.

• A hands-on engineering approach combined with an architectural mindset, with the ability to understand how and why the wider system works rather than focusing only on writing 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.
