Congrats on starting the ATPL grounds. As for good jobs to do while d/learning,I'm currently working as a Geophysicist in the oil/gas industry working 5 weeks on(exploration vessel) 5 weeks off(home). During the time off I am finishing an MPhil in Geodesy. This little arrangment works very well for me as the time I have off allows me to spend full days/weeks at a time dedicated to study. The money is generally very good and its all tax free. Well enough anyway to give up work next summer and fund a full modular course to FI level anyway
Other jobs with the same life style include navigators and electrical engineers as well as the more traditional drilling and production engineering side.
Hope this helps. If your interested let me know and I'll send you a list of exploration companies/websites.
