About the position

You’re tasked with developing customizable platform features suitable for enterprise scenarios within our primary product, Quollio Data Intelligence Cloud.

The role of an Individual Contributor at Quollio primarily encompasses three key responsibilities. Each of these is crucial to the ongoing development and future progression of our backend systems.

  2. Productive self-management

    Self-management at Quollio entails breaking down tasks into manageable segments, proactively communicating progress and any challenges to supervisors without requiring micromanagement.

It’s worth noting that you won’t be responsible for managing other team members.

Understanding the ‘what,’ ‘why,’ and ‘how’ behind tasks is essential for providing genuine value to users. Occasionally, decision-makers may err, and as the final coder before delivery, you possess a distinct opportunity to avert potential issues before they impact users.
