Positions in academia include faculty, administration and university counsel (which is much like an in-house corporate position). You can work for a law school or at any other level of the education system.
Faculty requirements vary by school; law schools generally require significant post J.D. experience before you apply, and for most positions, your law school grades are very important, as is the quality and depth of writing (i.e., law journal experience) you gained during school. A brief review of The AALS Directory of Law Teachers, will give you an indication of the backgrounds required law school faculty members. The Association of American Law Schools also publishes a placement bulletin. Undergraduate faculty and administrative position openings are listed in The Chronicle of Higher Education.
Many administrative positions, especially at law schools, are often filled by those with law degrees. Lawyers can be found in law school career services office (such as UA's), admissions offices, law clinics, and other student and alumni services offices. In these positions, one can expect to enjoy direct contact with current students, prospective students and those who have already graduated. The skills needed to succeed in these positions include organizational skills, counseling skills, analytical skills, and other skills these individuals may have honed in legal practice. Some of these positions may also be combined with teaching.
A hybrid position involving both faculty and administration is that of some librarians. Equipped with J.D.s and M.L.S.s, they give lectures and publish journals.
Universities also hire in-house counsels who act much like corporate counsel, giving advice on a full range of legal and other issues confronted by the school administration.
