· PHP | Laravel | React | PostgreSQL The Role

We’re looking for an experienced 2 x Senior Full-Stack Software Engineer to join an established technology business operating a large-scale SaaS platform.

This is not a ticket-based development role. You’ll take ownership of complex problems across the full software development lifecycle – understanding requirements, designing solutions, development, testing, release and production support.

The platform handles high-volume transactions, complex integrations and large set of data, so strong database and backend engineering skills are particularly important.

What You’ll Do

- Develop and maintain applications using PHP and Laravel.

- Build modern frontend functionality using React and TypeScript.

- Write and optimise complex PostgreSQL and raw SQL queries.

- Work with high-volume data, payments and transactional systems.

- Diagnose complex production issues across application, database and infrastructure layers.

- Identify technical risks,



edge cases and better solutions before development.

- Take ownership of projects from investigation through to production.

What We’re Looking For

- 5 years’ commercial software engineering experience.

- Strong PHP experience with Laravel or Symfony.

- Advanced PostgreSQL and SQL skills, including working beyond an ORM.

- Experience with React, TypeScript and JavaScript.

- Strong relational database design and performance optimisation experience.

- Experience working with payments, financial transactions or high-volume transactional systems.

- Experience with complex integrations or modernising large established software platforms

- Comfortable taking ownership while collaborating with other experienced engineers.

Why Join?

You’ll join an established technology business working on a mature, data-intensive platform with genuine technical complexity.

You’ll have the prospect to solve challenging engineering problems, take real ownership of your work and contribute to the future architecture and technical direction of the platform.
