"Developer II (Department of Health Policy & Management)"

Job Details

Johns Hopkins, founded in 1876, is America's first research university and home to nine world-class academic divisions working together as one university.

We are seeking a Developer II who will participate in the creation, implementation, maintenance, performance, production support and documentation of various departmental and enterprise-wide application systems. This includes but is not limited to the installation, modification, and testing of new and/or upgraded applications (packages or homegrown), operating systems, file structures, hardware, communication devices, and productivity tools. Applies analysis techniques and procedures to gather and then translate business requirements into functional/technical specifications and designs. Using functional specifications and designs, produces all or part of the deliverables. Maintains databases and application system code.

The Developer II position at METRC works with the Senior Cloud Engineer on the maintenance of existing, and development of new, research software. The METRC team runs multiple, longitudinal randomized clinical multi-site trials managed by a dedicated Data Engineering team. The ideal candidate will have domain experience, with a strong background in R and Python, and will be able to function as a developer working on the Data Engineering team. The team uses Basecamp instead of JIRA for coding and ticketing, but developing proficiency in either system will meet the project management needs o f the team.

Working on the development of research software means calibrating software design patterns, development life cycle, and product life cycle to follow the ebbs and flows of study life cycles. This is NOT a data analysis position. METRC developers are tasked with creating software that will work for years on current studies as well as future studies that have not yet been proposed, using an Agile-based DataOps methodology.

The successful candidate for the Developer II position will operate with an understanding of the Model View Controller and will develop proficiency in Modular Code Organization and Separation of Concerns in Application Design, allowing the developer to build out from study data pipelines and contribute to the existing codebase.
