Can't resist tooting my own horn. These are from my Klein bottle website:
TOPOLOGY CONSULTANT Part-time design of low-dimensional manifolds in glass, wool, plastic, titanium, niobium, pentium, and unobtanium. Ideal candidate is fresh out of college with 20 years experience in applied topology; and can solve Poincare's, Heawood's, and Hodge's conjectures. Pay & benefits are epsilon above unemployment. Compensation package includes trillions in worthless stock options.
GLASSBLOWER Construct borosilicate manifolds using lampwork. Handy with glass lathe, oxy-hydrogen torch, and bandaids. Must know the usual cuss words to describe breaks & cracks. Experienced in minor burn treatment. Special bonus if you know the difference between inside and outside.
MANIFOLD OPERATOR. Curvaceous, conformal Riemannian vector field desires normalized Ricci tensor with nice eigenvalues. Will relocate within proper metric space. No polymorphic permutations, please.
