.Net Developer III

About the position A Software Engineer III demonstrates proficiency in the technology of concern. They develop with more of an external focus – encompassing other teams and how the software interacts with other parts of the organization. They are proficient in the programming language and core library, including its more complex parts, numerous 3rd party libraries, and the tooling around development, building, debugging, testing, and deploying applications. They understand, at a moderate level, all components that make up the system and their inter-relationships and communication patterns. They can use this knowledge to develop complex subsystems using the principals they've learned and with an eye towards an approach with the idioms and patterns already present in the code and team. They have a deep understanding of the subset of components on which they are working and can mentor less experienced developers in the design of their code and the larger development ecosystem used within the project. A Software Engineer III is expected to consistently write high quality code, of a medium to high complexity, in a timely manner. This includes accounting for things like performance, maintainability, and security. In addition, it’s expected that they are proficient in all the standards, practices, guidelines, and idioms of the team and apply them as they are coding.
