Are you the kind of developer who thrives under the hood and enjoys building stable, scalable systems where data really matters?

At Flexbuy, we are looking for a backend developer who will take technical ownership of our web based platform and help scale, optimize and further develop the core of our product.

Our software makes it easy and free for companies to offer attractive employee benefits through salary deductions solutions. The platform integrates directly with payroll and financial systems, which means reliability, performance and data quality are critical.

About the role

Our core platform is built on a WordPress database architecture. This creates a familiar but technically complex environment where performance, structure and code quality are essential.

You will play a key role in developing and maintaining the backend layer and will work closely with both the business and decision makers.

Danish is not required for this role.

However, you must be fluent in English, as English is our primary working language in the development team and in technical communication.

Your main responsibilities

• Develop business logic in PHP

• Optimize and structure data in MySQL

• Build and maintain APIs and integrations between backend and frontend

• Ensure high performance and stability as the platform and data volume grow

• Continuously improve architecture and code quality
  

Your technical toolbox

We do not expect you to know everything, but we would like you to be confident in the following areas:

• PHP. You write clean, structured and secure code and are comfortable working with modern versions

• MySQL. You understand relations, joins, indexing and performance optimization

• WordPress under the hood. You understand the WordPress database structure such as wp_posts and wp_postmeta. We only use WooCommerce as a plugin

• jQuery. You can handle the scripts needed to connect frontend and backend
  
  

Direct impact and short decision paths

At Flexbuy, we value fast execution and minimal bureaucracy. You will work directly with the decision makers and have real influence on both technical choices and product direction.

If you identify an improvement in performance, architecture or data handling in the morning, we can often act on it the same day.

Who is Flexbuy?

Flexbuy provides employee benefits to companies across Denmark through salary deductions solutions and Choose Your Own Device programs.

We are a down to earth company in growth, focused on building reliable solutions and creating real value for both companies and employees.
