Simplify Jobs

Simplify's Take

What believers are saying

  • Confidential support: employees and family members receive free work-life coaching, including an around-the-clock crisis hotline.
  • Internal teaching: the trainer program rewards local and global knowledge sharing with a bonus.
  • Cloud exposure: the customer-success architect role combines platform design responsibilities with direct ownership of customer service outcomes.

What critics are saying

  • Country limit: the remote security-engineering role restricts remote work to Slovakia.
  • Eligibility filter: the security-engineering posting requires EU nationality for its sovereign-customer environments.
  • Language and travel: the cloud architect requires German and English at C1 level plus national and international travel.

What makes Deutsche Telekom IT Solutions Slovakia unique

  • Shared structure: the brand represents separate Slovak systems-solutions and IT-and-telecommunications legal entities.
  • Layered protection: security operations cover firewalls, proxies, intrusion detection, email filtering, antivirus, and data-leakage prevention.
  • Two-city presence: the Slovak operation maintains premises in Bratislava as well as its Košice base.
