The Software Engineer Sr. Principal is responsible for guiding software design and development across multiple engineering teams and principal software engineers working on various projects including contact center systems. Sr. Principals will help accelerate delivery speed and quality through technical expertise, technical leadership, and by communicating best practices within their assigned IT portfolios. They will be a key contact point across a large portfolio for sharing and engaging with principal software engineers to foster learning and adoption of new technologies. They will interface with our 3rd party vendors to ensure THD's technical needs are met and that we are driving interoperability within our existing technology landscape. The role will typically support 4-6 different development teams (contrasted with 2-3 for a Principal and 6-10 for a Distinguished Engineer) which will span a variety of functioning products and/or APIs. They will ensure that teams are making good use of resources, designing and refactoring systems to optimize cloud costs, and will be responsible for identifying opportunities to streamline processes and optimize existing codebases.
