    Assuming SQL Server 2005+

    WITH E AS
(
SELECT 
   aId
   , Position
   , StartDate
   ,  Enddate
   ,ROW_NUMBER() OVER (PARTITION BY aId ORDER BY 
             CASE WHEN Enddate IS NULL THEN 0 ELSE 1 END ASC, 
             (CAST(Enddate as datetime)) DESC) AS RN
FROM EmploymentDetails ed 
)
LatestJob AS (SELECT  aId, Position, StartDate,  Enddate FROM E WHERE RN=1), 
EarliestStart AS (SELECT ...

    By the way why are you storing dates as varchar rather than date (SQL2008) or datetime? Edit I see this last issue is now fixed in the question.
