Deutsche Telekom Digital Labs

Deutsche Telekom Digital Labs is the Indian engineering centre of the German telecommunications group Deutsche Telekom, established in Gurgaon in 2018. Its teams build the digital products the group ships across its European markets, including the customer applications used by mobile and broadband subscribers, the commerce and ordering systems behind them, television and streaming clients, and the platform and data infrastructure shared between national operating companies. The centre works as a product organisation rather than an outsourcing vendor, owning services end to end and releasing them into several European markets at once.
