The question is a bit broad and rather subjective, but I think it's a good one, nonetheless. There are as many answers as shamans, though: it depends on the person and their circumstances as much as on their totem.
Here, let me present a few examples I'd consider stereotypical (though YMMV, wildly, of course.)
First of all, imo, practically any shaman can be, you know, a shaman. :) A spiritual leader like a priest, for a group of people willingly associating with the totem and with the belief system and mythology the totem is a part of.
Bear: She's a pro trainer in a gym or a health club in the suburbs. She can show you how to get stronger (like her), and she can fix you up quick if you get hurt.
Cat: She's an independent coach who helps you get on with your life and land on your feet when in trouble. Or she's a private investigator. Or an independent reporter (with her exclusive, highly popular online channel about business, health, celebrities, art, fashion, cooking, whatever.)
Coyote: He's a con man. Some companies might think he's working for them as a salesperson. Big mistake.
Dog: He's a janitor at a local school. Or works in a kindergarten.
Eagle: She's an environmental activist working as a lone agent for a large organization. A ranger, perhaps?
Gator: He's an officer, or overseer working for a wastewater treatment company. Or perhaps even its CEO.
Lion: He's also a CEO, probably of a startup (developing games and/or surveillance software), that will be worth zillions in a few years.
Owl: She works as a flight instructor, specialized in night flights. (Day flight training is handled by her companion, with whom they have a small company.)
Raccoon: He's an art buyer, traveling the world, hunting for the most exquisite pieces to buy. Or to, you know, acquire. Somehow. Anyhow.
Rat: I know it's a stereotype, but if anyone, she's a squatter.
Raven: Just like Coyote, she's a con artist, working rural areas under the guise of a salesperson for a firm providing exclusive funerary services.
Snake: She's a traveling advisor / internal affairs inspector / lawyer for a megacorporation.
Wolf: He's a lumberjack. Or a farmer. And he's not alone.
Well, that's my take on most likely shaman professions / occupations. But, remember, it all depends on who they are and where they're coming from. :)
And, of course, spells and spirits and magical stuff do come into play in most of these cases, should they be needed and useful.
