Senior Database Engineer

Jembi Health Systems NPC is recruiting a Senior Database Engineer to join our cutting edge Health Information Systems team in Durban.

The role will entail design, development and deployment of large clinical data warehouses that will be used by Departments of Health. Large and often complex health data sets will need to be imported from multiple sources, both transnationally and in large batches. These data are then mapped and analysed, and consumed by a number of applications including a web viewer. Complex business logic procedures need to be developed for deduplication of patient records as well as for an inference engine that can generate health events from various data. A proof of concept system is in operation in one province of South Africa and this needs to be generalized.

There will be some work developing and analysing data elements and health indicators, cleaning dirty data and optimising ETL processes. The candidate should have a exceptional understanding of relational databases, data analysis and data mapping, and have a strong background in database programing, as well as in disk configuration (RAID etc) and backup strategies. There will be a mix of database development and database administration, and the role will involve working with representatives from Provincial Departments of Health and other organisations such as the National Health Laboratory Services, National Department of Health and many other Non-Governmental Organisations such as the Bill and Melinda Gates Foundation, UNICEF, Medicines Sans Frontiers and others.

Technologies used depend on the project, with all the major stack covered and with some projects there is flexibility to explore new technologies:
1. Microsoft Server stack
2. MySQL
3. Postgres
4. MongoDB

Experience with statistical modelling, quantitative research methods and trend analysis are all a definite advantage, as is experience with web technologies and APIs.
