What is Scribbr? 🎓

We are a family of graduates who have one mutual goal: Help students graduate!

Scribbr helps more than 300 students daily, offering our Proofreading & Editing service, the Scribbr Plagiarism Check and more than 1.500 articles (and over 5 million monthly page views) written about thesis topics.

Together with our team in Amsterdam, and more than 500 freelance-editors, we do everything possible to provide the best service for students. This passion has earned us a customer satisfaction score of 9.9/10 from over 1.000 verified reviews.

Since its founding in 2012, Scribbr has evolved from a side-project in an unexplored market to one of the fastest-growing businesses in Europe.

We're looking for a Senior PHP Developer that can help us improve our current services and strengthen our development team as we prepare to launch into new and exciting markets with huge growth potential.

Our tech stack: PHP 7.2, Symfony 4, Doctrine, MySQL 8, Redis, RabbitMQ, Vue.js, AWS, Docker, Scrutinizer, PHPStan, PHPUnit, Sentry, CircleCI, GitHub, DDD.

What will your responsibilities look like?

  • Working together with the team of software engineers, developing our core software products
  • Participating in technical discussions and bringing your best ideas to the table
  • Taking part in designing software application architecture applying Domain Driven Design (DDD) principles
  • Raising the bar for our development standards & delivering high quality software
  • Providing frequent code-reviews and feedback for the other team members
  • Constantly improving our software and engineering practices

What application/codebase will you be working on?

The Scribbr application is split into two components: our super high-traffic marketing website, which is built in Wordpress, and our Symfony order management system (Symfony) called Houston. You will be working on the latter ;-)

Houston is used by students, the support team, the marketing team and the management team to run Scribbr smoothly. We are improving Houston every day to automate more of our processes and to improve the services we deliver.

Some Houston features

  • Process orders and payments of our customers.
  • Manage our vast freelance editor pool.
  • Matching freelance editors and orders via an algorithm based on statistical data.
  • Automatic Word-document analysis to track and assess the performance of our freelance editors.
  • Multi-currency and multi-language operations; students from all over the world use our services.
  • Complete CRM-system to help all students.
  • Plagiarism-detection software.

… and a bit more technical?

Continuously evolving our model is part of Scribbr’s DNA. That is why we use Domain Driven Design as our approach. Our domain code reveals exactly what our business is about. 

Aggregate roots inform other contexts using domain events to make sure tight coupling happens only as a design decision. Value objects are used to communicate, and their immutability results in predictable and testable behavior. Symfony is mainly there to make our lives easier. Because we use the latest version, we make use of autowiring to keep configuring service definitions to a minimum. Less code = more.

Who will you work with?

We're enthusiastic, we're international and we love to celebrate success! We work together to ensure that students are fully satisfied with our services and that Scribbr keeps on growing.
