  • Routing and Places: Computing routes using OSRM and Google Maps.

  
  

  • Dynamic Search: Powering features like Smart Stopovers via our meeting-points service.

  
  
  
  



• Collaborate with the Product Manager and other engineers to refine requirements and translate business needs into robust technical solutions.




• Uphold and improve the team's code quality standards, providing detailed feedback and mentorship through code reviews.




• Document the solutions we build and ensure our APIs and services are well understood by consumer teams.
