Amazon is ramping up recruitment within its Alexa and Echo divisions by advertising for 400 positions which currently remain unfilled.
Recruits are being sought in the fields of data engineers, product managers and machine learning scientists at locations ranging from the US to Poland.
The recruitment frenzy dovetails with the release of a range of new devices compatible with its Echo voice controlled speakers which have proven to be a greater success than first envisaged.
This includes a budget Amazon Echo Dot which enables voice control of traditional speakers as the e-tailer seeks to position itself front and centre of a talk to shop revolution.
In a statement Amazon said: "It is still Day One for the team to work on audio, automatic speech recognition, and natural language solutions that revolutionize how customers interact with Amazon’s products and services.
"The Alexa platform is working on other voice-activated Amazon Devices, like Amazon Fire TV, and extending into working with connected smart home products through the Alexa Voice Service. Additionally, the Alexa Skills Kit (ASK) allows third-party developers to easily build and add their own skills to Alexa, like purchasing tickets through StubHub."
