Build modern frontend functionality using React and TypeScript.

n

Write and optimise complex PostgreSQL and raw SQL queries.

n

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

n

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

n

Identify technical risks,



edge cases and better solutions before development.

n

Take ownership of projects from investigation through to production.

What We’re Looking For n

5+ years’ commercial software engineering experience.

n

Strong PHP experience with Laravel or Symfony.

n

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

n

Strong relational database design and performance optimisation experience.

n

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

n

Experience with complex integrations or modernising large established software platforms

n

Comfortable taking ownership while collaborating with other experienced engineers.

Why Join? n

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

n

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