You have not stated the purpose of the election. You are electing
"seats," but seats in what? Is the goal recognition of the
colleagues, or is it representation in a decision-making council?

Well, you haven't given us enough information. What are you doing?
There are "30 candidates" for "15 seats." Why are you holding an
election at all?
If the goal were representation, Asset Voting, which is a variant on
STV where exhausted ballots or extra ballots (above quota) can be
recast by those who received them, is about perfect. With this small
number, you'd hold the election and then those who received votes
would meet and work out how to distribute the votes. There are
details that might not be obvious, such as quota (Hare or Droop, and
those who are accustomed to thinking of deterministic methods will go
for Droop, whereas those who see the value of encouraging compromise
will go for Hare, and allow those who refuse to compromise *to be
Otherwise what I'd suggest would be electing a "recognition
committee" -- use Asset! -- that is small enough to meet (in person
or by email) and decide things deliberatively, and let this committee
gather information, interview candidates and collect reports, etc.
(I.e., the "electorate" could be asked to rate candidates; the
committee can use this information flexibly.)
Asset voting is a device for boiling a group down to a smaller group
that fully -- or almost fully -- represents a larger group.
