There's no need to be secretive, it's within the rules to work whilst in the military, if you have the permission of your CO - Just ask some of the bouncers around any garrison town. What is not permitted is to work during any of the Graduated Resettlement Days (GRT). GRT days can be used on courses or taken as work experience and can be taken at any stage in your final 2 years of service. The trick then is to use the GRT days first on courses or work experience followed by leave that has been saved up and then terminal leave. If you have been offered a job and need to start straight away fill out the forms to do "work experience" with your new company and ask them to give you the equivelent money as a sign on bonus once you've used up the GRT days. The added bonus is that you can claim your food and accomodation whilst on work experience.
