z/OS Security Backend Developer/Architect

Working at IBM is more than a job – it’s a calling: To build. To design. To code. To consult. To think along with clients and sell. To make markets. To invent. To collaborate. Not just to do something better but to attempt things you’ve never thought possible. Are you ready to lead in this new era of technology and solve some of the world’s most challenging problems? If so lets talk.

Your Role and Responsibilities

We are looking for an experienced zSystem Security Software Developer/Architect.

In the Delft Software Lab we develop security software for the IBM Mainframe platform (z Servers) and are an addition to the zOS security subsystems.

Our software will exploit z/OS and z/VM operating system features and is interwoven with multiple z/OS security software products as RACF ACF2 and Top Secret. In addition we also support multiple subsystems like CICS IMS DB/2 and MQ and send security related data to external products like QRadar and ArcSight.

As software developer/architect you will be part of a development team that executes the tasks required to fully develop and test an IBM security product to ensure it functions according to specifications client requirements and will also meets the business needs

You have an in-depth knowledge of the logical function(s) that he/she is responsible for. A fundamental knowledge of the overall solution is therefore also required. Good knowledge of the target market that is covered by our products and a good understanding of the client environment is considered to be an important added value.

The development activities cover all aspects of the product. This will include design building and testing but also performing code reviews and giving demos of the built solution. The developer is working closely together with the tester and in colloquy with the tester the developer will also develop specific test scenarios.

Based on the requirements and the design the developer should be able to build the required functionality define or help to define the testing criteria and develop test cases/scenarios/use cases. The developer can occasionally be asked to test software developed by one of the other team members and/or execute the required tests.

We are using key components of the Agile development cycle and the developer needs to provide feedback on usability serviceability and documentation and reports the current status to the appropriate audience so the developer will work closely together with other team members. Our backlog planning can start on an epic level and will be broken into stories that can be executed during fixed length sprints.

As both our software and the z platform are considered to be highly complex the will to succeed a strong personal drive and the ability to think analytically above average are considered to be very important personal abilities.
