Interpreter = correctly translating one language to another.
Nutritionist = planning & promoting healthy meals.
Software developer = designing & testing software programs/software.
Physician = properly & effectively diagnose and treat illnesses/disease..etc
Surgeon = to operate as needed on patient in a safe, effective, & hygenic way.
Accountant = to handle either personal/business finances.  they sometimes work in accounts payable or receivables, issue credits due to accounts, money handling..etc.
Security Guard = helps prevent theft in public place like stores.  they keep parking lots safer by patrolling.  some use video surveillance on the job to watch for trouble. 
Hope all that helps in some way.
