Developer at Discovery Limited

Key Purpose

• The role has multiple facets, the first being to become completely familiar with existing software models to maintain and enhance them. Equally important is the development of new software models and functionality for the team.
• A less challenging but equally important role is running the software programs on a daily and monthly basis – these are called production runs. The programs that need to be run include software developed in-house as well as third party software. For all these, the  input files need to be created, usually by means of C/C++ programs, SQL and shell scripting. Some of these input files themselves can be complex in nature, being created of data from multiple sources.
• Running these production runs can involve working outside of office hours, for which time off is granted in lieu of overtime pay. Finally a requirement is to develop ad-hoc programs and front-ends for the team to be able to run various programs themselves – usually through a web page.
• It is important for the candidate to be able to work on their own to solve various technical challenges that may arise. Thought must be given to the latest  and future  technologies and methodologies that may better address these challenges. Although C/C++ has traditionally been used for its superior performance, an open mind must be kept to using the correct technology to address current and future requirements.
• Although guidance will be provided at the beginning, the candidate must work towards being able to make decisions on their own. To this end, a good understanding must be gained of the basic clinical principles, such as clinical coding, that are instrumental in all software developed and run by the team. It is also expected of the candidate to keep current with new developments in software and modelling techniques

Areas of responsibility include but may not be limited to 

• Maintaining and enhancing existing software
• Developing new software
• Creating input files

• Keeping third party software up to date by updating license keys etc.
• Developing ad-hoc programs and scripts as required by the team
• Investigating new technologies and methodologies to keep the software current.
