Job Description

You will be part of a small and motivated team, actively contributing to the development of our various web applications. Most of your time will be spent working on our online surveying platforms, which total more than one million visitors per month – a number that is growing at a rapid pace. Our newest product,, will receive the most of your attention.

You will be deeply involved in the design process for new exciting product requirements and take over responsibility for considerable parts of our existing PHP code base. Based on new requirements, you will independently analyze and elaborate possible software designs and implement them on your own, while closely working with other Back-End and Front-End Developers.

Ideally, you will also optimize our databases, improve our continuous integration processes, set up and maintain our AWS resources, extend our API and third-party integrations, give technical support to other team members, and much more.

Skills & Requirements

It is easy to underestimate the technical challenges of running an online survey platform on a large scale: Users will share their surveys with as many people as possible, often resulting in unannounced, dramatic traffic spikes. Our platform must be highly available and scalable, as well as maintaining fast loading times, because survey participants won't "just come back later" if it is down; We save and process large amounts of data that needs to be made available to our users in real-time. This data is often sensitive, so security is also a very important aspect of our work; We send millions of user generated emails (survey invitations) and need to ensure that they are delivered, all while preventing abuse from spam and phishing attempts. We offer a vast number of features, resulting in a large and complex code base. Maintainable and extendable code, automated tests and a well-organized software architecture is key to the continuation of our success.

This is what we are looking for:

  • University degree in Computer Science / Software Engineering, or equivalent qualifications
  • Proven expertise as a Back-End Developer in PHP
  • Rock-solid engineer mastering object-oriented programming and common design patterns
  • Great experience with SQL and working with large data sets
  • Comfortable with Linux, having no problem to set up and maintain web application servers and other back-end resources
  • Good knowledge of the full stack of modern web applications including HTML5 and JavaScript
  • You are fluent in English

One or more of these are a big plus:

  • Proficient in at least one more programming language other than PHP or JavaScript
  • Able to describe your software design and applied design patterns using UML
  • Practice test-driven development by default
  • Know-how in managing continuous integration processes
  • Experience with Amazon Web Services (AWS)
  • Already used tools such as Git (GitHub), Gulp, TeamCity or Jenkins, TypeScript, IntelliJ/PHPStorm
  • Experience in working in an agile team
  • You speak (Swiss) German
