Your role in the team

• 
  
• In this role you will shape the future of software that seamlessly connects physical branches worldwide with real-time technology.
• 
  
• You will design and lead software architecture for over 2,000 branches in more than 110 countries.
• 
  
• Your role combines deep technical insight with hands-on presence in the field, bridging software and hardware to enable the next generation of SIXT’s rental experience.
• 
  
• You set the architectural direction for the software that runs every SIXT branch.
• 
  
• Counter, checkout, key handover, vehicle exchange and return, plus the devices and IT services connecting them.
• 
  
• End-to-end across the branch surface.
• 
  
• You design at the software ↔ hardware intersection.
• 
  
• Counter PCs, customer tablets, POS terminals, scanners, keyboxes — you model how our software speaks to physical devices in real time, and you shape the integration patterns the whole organisation will adopt.
• 
  
• You drive system-design choices across the branch domain — event-driven flows, API contracts, state ownership, device-to-cloud protocols, the boundaries between modern services and legacy interfaces.
• 
  
• This is hands-on architecture, not architecture-by-slide-deck.
• 
  
• You grow the engineering practice around you — across the multiple teams that touch the branch (Checkout, Counter, Rental Platform, Turnaround, Keybox, Tablet/POS) through clean design docs, sharp technical reviews, and hands-on engagement when a problem is gnarly enough to warrant it.
• 
  
• You spend real time at the branches.
• 
  
• The strongest architecture is shaped where the system actually runs — with agents, with devices, and with customers.
