• Experience analysing complex business processes and translating them into reliable technical solutions.
• Proven ownership of critical applications, incidents and production processes.
• Insurance or banking experience is an advantage.

Technical and functional requirements:

• Advanced COBOL application development skills.
• Strong SQL/DB2 or SQL Server knowledge, including performance considerations.
• Technical analysis, solution design, debugging and troubleshooting skills.
• Experience with testing, deployment and production support.
• Understanding of application modernisation and integration with other technologies.

OUR VISION:

Success in industry often relies on key individuals who demonstrate intrapreneurial leadership - those who continuously initiate, transform, and pursue excellence.

The best way to develop this strength is through ad interim projects, i.e. working as a consultant with established intrapreneurs in international companies, to support their major expansion or improvement initiatives regarding governance, studies, or operations.

Since 2014, AETHER is managing these opportunities for outstanding consultants in key international groups, as these offer greater learning opportunities with multi-million impacts.
