Adfinis drives digitalization with open standards and technologies, shaping a world of innovative, sustainable, and resilient IT solutions based on trusted open-source technology.

As our company grows, we want to strengthen and complement the skills of our development team, which designs and implements web-based applications that enable our customers to digitize their work processes.

At the core of our development stack are single-page applications based on Ember.js (JavaScript), which are connected to backend services based on Django (Python) and PostgreSQL via REST or GraphQL APIs.

As a Professional Web Developer, you will work on customer projects, implementing new features and modules, as well as maintaining and refactoring applications to ensure their longevity. You can focus on either the frontend or the backend, but are also welcome to work within the full stack.

Your tasks and duties will include:

  • Acting as a technical lead in projects with a straightforward scope that typically involve another internal or external contributor

  • Designing and refactoring functions and modules within established guidelines

  • Reviewing merge requests for validity, coding style, and functional depth, and discussing review findings in a critical and constructive way

  • You can write unit tests for different cases (e.g., invalid inputs, missing permissions) that cover the most relevant aspects of a module or feature.

  • You have a good working knowledge about error handling fundamentals (e.g., logging errors, displaying useful error messages) and can write code that handles most errors and exceptions while keeping the program running.

Must-Have Soft Skills

  • You work thoroughly and diligently, are dependable and reliable, take responsibility for your actions and decisions, and strive for error-free, high-quality results.

  • You seek, identify, create, and capitalize on opportunities, initiate change, and foster improvement through proactive, decisive action.
