Leidos is seeking a Software Developer for a 200+ FTE technical development program supporting the Sponsor’s Entitlement Programs as well as IdAM /ICAM, Authentication, Authorization, Attributes and Digital Policy Management. The Software Developer will work with a large team of developers, software engineers, and data engineers.
The Developer will be part of a team of developers that are building a new application that utilizes LLM to convert data and access policies from a variety of sources and formats into a uniform format for compliance assessment. The Developer works closely with product owners, business analysts, and other teams to translate business requirements into technical solutions. The Developer will analyze and decompose complex software systems and create designs for scalability, testability, and performance. Our work rhythm revolves around the Scrum agile framework to deliver incremental enhancements on a 2-week cycle. Developers actively participate in planning deliverables and grooming the Jira backlog. We rely on team collaboration to continually fine tune performance and ensure clear communication.
