Team Culture

The Cogent Labs engineering department is continuously working towards developing a culture improving and rewarding the following qualities:

  • Team effort: A cohesive team can be more effective than an isolated prodigy. Engineers are expected to work well in groups and look for opportunities to empower their colleagues.
  • Ownership: Take full responsibility for your own projects and tasks and if needed, cross over boundaries in order to successfully deliver your project.
  • Self-improvement: Create an environment where engineers can focus on their engineering tasks and self-improvement without excessive outside disturbances.
  • Experimentation: Engineers should have some freedom in experimenting with new ideas and technologies, as this ultimately could translate into building better products or the creation of valuable new IP.
  • Quality & Excellence: Maintaining a mindset of developing high quality features and code. We avoid cutting corners as much as possible.
  • Customer Service: Being customer focused, not only externally but internally as well. This means developing services that not only improve the experience of our end customers, but also being ‘customer service’ oriented within your team and the company as a whole by helping out others and sharing knowledge.
