My job title at Setec Oy was R&D Engineer. I mostly worked with smart card readers, especially with their software. For example, I am the main author of SETROS (Setec Reader Operating System) which is realtime multitasking operating system. An application program which runs on top of the SETROS has been evaluated and certified at ITSEC E4-level.
I also worked with device drivers (or daemons) and interface libraries for accessing smart card readers under MS-DOS, Windows 3.x, Windows NT, OS/2 and Unixes. In most cases Windows NT dependant parts were written by another person.
I was also the System Administrator of the Windows NT file and print server. The administration included planning and execution of account, backup, network, etc. management procedures.
I am making test tools used mainly by integration testers. Most of my time there goes to development of the Test Execution Language (TEL) compiler and executor of the resulted bytecode. The compiler and the executor are part of the Holistic Integration Tester (HIT) testing tool.
I have been lucky sofar to have jobs giving lots of challenges in areas I am interested in.
