About the project

Pentalog Mexico is looking for a Senior Back-End Engineer (Java) to join our fast-growing team.

Client & project information:

Our client & partner is the largest travel site in the world, visited by over 500 million travelers each month. Travelers across the globe use this site and app to browse more than 859 million reviews and opinions of 8.6 million accommodations, restaurants, experiences, airlines and cruises.

Across the team, we’ve worked hard to create an atmosphere of “Speed Wins” – minimizing process, shipping products quickly and doing everything to avoid big company paralysis.

This is a very bottom-up organization: there are no software architects thinking deep thoughts and directing the action from above. We trust our engineers to come up with, implement and take responsibility for their own designs.
