A penalty loading of 15% is the statutory minimum under the FA2008 rules for penalties for inaccuracies, so in one sense you should be grateful to have received the maximum reduction for the quality of your disclosure (the statutory range for "careless" is 15% to 30%).
Carelessness is synonymous with negligence. Interestingly, the definition of negligence still being relied upon comes from the Birmingham Waterworks case – in the year 1856 I think. Negligence (among other things) is not doing something that a reasonable man would be expected to do, and doing something which a reasonable man would not be expected to do. Later cases have established that a reasonable man (among other things) would be expected to make a full and correct return of all sources of income. He would also be expected to seek professional assistance with matters he is unable to deal with properly himself.
If you have omitted one of two or three sources of employment income, then I don’t think you can argue against a penalty. But if this was one of ten sources, then you might have a chance. But you would still have to explain precisely what you did – back to the reasonable man completing his tax return, I would expect him to think about the employments that he had during the year and ensure that he had a P45 or P14 for each one, which would be used to complete the employment pages.
So who completed your tax return? What checks were carried out to ensure that all employments had been included? Was the overpayment of £3,000 expected or a surprise? If a surprise, did you contact HMRC to see what might be wrong? The fact that the money was not repaid is irrelevant - what matters is the return itself, which you declared to be correct and complete.
