This query
SELECT j.JOB_ID, s.SCTYPE, SUM(c.POPU)/(SUM(c.POPU)/SUM(c.POPU/c.POUEST)) AS EstHours
FROM ccode c
INNER JOIN sccode s ON s.SCCODE_ID = c.SCCODE_ID
INNER JOIN job j ON c.JOB_ID = j.JOB_ID
WHERE j.JOB_ID = 7398
AND s.SCTYPE IN (1,2,3,4,5,6,7)
AND c.POPU > 0
AND (j.DELETED != 'Y'OR j.DELETED IS NULL)
AND (c.DELETED != 'Y'OR c.DELETED IS NULL)
AND (s.DELETED != 'Y'OR s.DELETED IS NULL)
GROUP BY j.JOB_ID, s.SCTYPE;

returns
JOB_ID   SCTYPE   EstHours
7398          1           3280.53
7398          3           1893.76
 
This query
SELECT a.POEST
FROM (SELECT MAX(c.POPU) POPU, c.POEST
FROM ccode c
JOIN sccode s ON s.SCCODE_ID = c.SCCODE_ID
JOIN job j ON j.JOB_ID = c.JOB_ID
WHERE j.JOB_ID = 7398
AND s.SCTYPE IN (1,2,3,4,5,6,7)
AND c.POPU > 0
GROUP BY j.JOB_ID, s.SCTYPE)a;

returns
POEST
24.64
25.09

I would like to join/rewite this to ouput (Total = EstHours * POEST)
JOB_ID   SCTYPE   EstHours    POEST         TOTAL
7398          1           3280.53          24.64           80832.26
7398          3           1893.76          25.09           47514.44

just include the sctype in the selected columns of your second query.
Since it's part of the group by it won't affect the results.

Then join on sctype between the two queries...

SELECT a.job_id,
       a.sctype,
       a.esthours,
       b.poest,
       (a.esthours * b.poest) AS total
  FROM (  SELECT j.job_id, s.sctype, SUM(c.popu) / (SUM(c.popu) / SUM(c.popu / c.pouest)) AS esthours
            FROM ccode c
                 INNER JOIN sccode s ON s.sccode_id = c.sccode_id
                 INNER JOIN job j ON c.job_id = j.job_id
           WHERE j.job_id = 7398
             AND s.sctype IN (1,
                              2,
                              3,
                              4,
                              5,
                              6,
                              7)
             AND c.popu > 0
             AND (j.deleted != 'Y' OR j.deleted IS NULL)
             AND (c.deleted != 'Y' OR c.deleted IS NULL)
             AND (s.deleted != 'Y' OR s.deleted IS NULL)
        GROUP BY j.job_id, s.sctype) a
       INNER JOIN (SELECT x.sctype, x.poest
                     FROM (  SELECT s.sctype, MAX(c.popu) popu, c.poest
                               FROM ccode c
                                    JOIN sccode s ON s.sccode_id = c.sccode_id
                                    JOIN job j ON j.job_id = c.job_id
                              WHERE j.job_id = 7398
                                AND s.sctype IN (1,
                                                 2,
                                                 3,
                                                 4,
                                                 5,
                                                 6,
                                                 7)
                                AND c.popu > 0
                           GROUP BY j.job_id, s.sctype) x) b
           ON a.sctype = b.sctype;
