The recently updated website for President Joe Biden's White House carried an invitation for tech specialists savvy enough to find it.
Hidden in the HTML code on https://www.whitehouse.gov/ was an invitation to join the US Digital Service, a technology unit within the White House.
Former president Barack Obama launched the service in 2014 to recruit technologists to help revamp government services - for example by modernizing Medicare's payment system or reforming hiring practices across government agencies.
Tech specialists join the Digital Service for typically one or two years.
