Senior Backend Engineer (m/f/d) PHP (Laravel Ecosystem)

Start date: as of today

About Us

At our Convidera Campus in Cologne we set up Innovation Labs in cooperation with leading medium-sized companies: Here, digital projects are continuously developed, from the idea to the implementation. With us, the strengths of an established market leader are combined with the agility and spirit of a start-up.
Therefore, we are looking for You: As a Senior Backend Developer (m/f/d) with passion you work with us in an agile, multidisciplinary team.
Being part of the digitalization family, we often find ourselves working in multiple projects spanning multiple domains. This gives us the opportunity to use the right solution for the right problem. To be good at that, we foster continuous learning and have built a fail-safe environment for team building and learning. We don’t want just want to know ‘what’, we want to know ‘why’.

What are Your tasks

  • Lead the entire web application development life cycle right from ideation to releases and
  • Build the right solutions for the right problems.
  • Build a family of great developers.
  • Improve our code quality and learning opportunity.

What we offer You

Real Responsibility and room for your personal growth.
What exactly is ‘Responsibility’? How is this determined? Is there a general rule for identifying this? If there is, how do you teach this to your junior colleagues? As aptly put by Tom Hombergs: “Sadly, it's very easy for a reason to change to propagate through code via the dependencies of a component to other components.” (Tom Hombergs, Get Your Hands Dirty on Clean Architecture, Ch. 2).
Considering this, would you ever consider it okay for changes in a dependent component to also be an additional reason for another component to change? To you, does this violate SRP? How would you like to give a 15 mins internal tech talk about your opinion every other week? This is the environment we are actively pushing to create, balancing “doing the right thing” with “doing things right”.

And in addition:

  • An international competent team that finds solutions in an independent way of working,
    enthusiastically supports you and relies on flat hierarchies.
  • A committed, relaxed corporate culture without a dress code, with fresh fruits, water,
    soda and endless coffee.
  • Flexible trusted working hours, the option for home office and a state-of-the-art working
  • Stylish offices in the heart of Cologne with a loft, roof terraces and our Digital Campus

What we expect from You

  • Profund education in Computer Science
  • Broad practical experience in a StartUp, agency or digital consulting company
  • Great understanding of how Laravel works and PHP.
  • In-depth knowledge of object-oriented analysis/design and domain modelling.
  • Experience in coaching and mentoring junior developers.
  • Sound knowledge of various application architectural patterns.
  • Experience with building APIs.
  • Experience with software testing – Unit and Integration testing.
  • Experience with CI/CD and microservices using docker.
  • Good communcation in English.

Sounds great?
