Senior Software Engineer

Software Development Engineers [Integrated Engineers] are responsible for the development of computer programming systems and applications, including the design, coding, testing, and deployment of products and solutions to meet firm obligations. The Software Development Engineering focus specializes in the design, development, and testing of software systems for software enhancements and new products, including cloud-based or internet-related tools. They conduct and evaluate application audits and testing processes and ensure that the applications or products meet the defined quality standards. They may also create documentation so that future managers and engineers can troubleshoot potential issues. In addition to software design and development skill sets, employees in these roles should have in-depth knowledge of automated testing tools and traditional quality assurance approaches.

Senior Professional roles typically require 5 – 10 years of related experience.
