Wanted: PHP Backend Superhero

As a web developer at LinkORB you will make sure your products are loved by your customers and are ridiculously fast.

What you tell your friends you do

“I build web apps. And no – I will not fix your computer.”

What you will really be doing

  • Control the development of your own product group
  • Make architectural designs for backend functionality
  • Build micro-services that build your product
  • Design and build developer friendly APIs
  • Create and improve models
  • Work on core/framework level functionality
  • Performance optimisations
  • Refactorring
  • Complex debugging and profiling
  • Improve our scores on Scrutinizer CI
  • Work directly with our admins to get your new functionality into production

If this is your bread-and-butter, and are up for a challenge, this one’s for you!

About you

You are a veteran PHP backend developer that likes to challenge yourself

  • You hack on, and research into, challenging projects in your free time
  • You archive your e-mail in Elastic Search
  • You enjoy teaching and helping team-mates
  • You enjoy working with front-end developers to create finished products for end-users
  • You pick up whenever something needs attention, even if it’s not directly in your job description
  • You will be using the right tools for whatever job will be thrown at you. Choices that were made in the past are not rules.
  • You prioritize your own work together with your team and Product Owner. You will receive immediate feedback from end users and you will have a lot of opportunities to experiment.
  • You will work in a motivated team to meet ambitious deadlines. There is always a budget for good ideas.
  • Big data is your guru, your gut feeling isn’t. To measure is to know.

What we have worked on last quarter

Faceted search : Search and filter real-time product information, hundreds of times per second, for 90.000 products in 280 shops.

Responsive design : One codebase, lots of devices, but always the optimal user experience.

Reviews : A completely new infrastructure for better performance and scalability. Improved usability for both customers and moderators. More reviews, more interaction, less spam, better conversion rates.

What a day in the office might look like

You open a pull request in GitHub for your last changes in the Javascript codebase of one of the back-end services for our new faceted-search functionality. You have fixed a bug in a de-serialisation method that was causing metadata to leak from JSON objects. Considering the large amount of simultaneous, relatively small requests these services process, Node.js seemed the obvious choice. So you had to abandon your usual work field of PHP and give the old Javascript another chance. Once again it proved itself a powerful language, capable of building beautiful stuff. Maybe the front-enders were right after all? Now that this has been tackled, you return to PHP. You had this idea to optimise the determination of the sorting order of the filters on the site…


You will be working in a team with three to five other developers, each of them with their own specialization, ranging from PHP to Javascript. Your team will be complemented by a Scrum Master and a Product Owner.

Required experience and Skills

  • Preferably university-level degree in Computer Science, Electronic Engineering or Mathematics.
  • Minimum of five years experience in a similar position.

  • Demonstratable advanced experience in Symfony or Silex is a must.
  • You enjoy working on large distributed applications.
  • Demonstrable skills in backend software design and development.
  • Experienced with technologies like messaging (activemq/rabbitmq/stomp), caching (memcache, redis), nosql, search (elastic search), objectstorage (gridfs, s3, etc..).
  • You have developed developer-friendly APIs.
  • You understand and investigate what a user wants and feels.
  • You enjoy working closely with Ops and propose/communicate infrastructural improvements.
