Working with Mayor Ken Livingstone and Richard Rogers, Livingstone's chief advisor on architecture, the 20-strong panel will be charged with ensuring 'high-quality urban design' is delivered on all LDA projects.
As well as helping with selecting practices, the panel will also be asked to draw up design and feasibility studies and carry out design reviews.
The posts are open to either individual architects or entire practices who are prepared to work between 10 and 60 days a year for the agency.
Applicants must have specialist skills in one of a number of key areas, including urban design, landscape design, masterplanning and urban strategy.
A spokesman for the LDA said: 'We need to harness the highest-quality urban design and architecture to realise our commitment to achieving sustainable communities.'
However, how the panel will work with the hotly discussed role of London's soon-to-be-appointed director of design remains unclear.
The deadline for entries for the panel is 12 October. For more information visit www.mytenders.org
