Job description

PLEASE NOTE: This position requires an ACTIVE Top Secret/SCI Clearance with Polygraph. To be considered for this position, you MUST have an ACTIVE Clearance Level of Top Secret/SCI with Polygraph

The Sponsor requires project management and technical support to manage projects and to perform software development activities within budget in the areas of enabling search against structured and unstructured data sets; federating searches across external data sources; coordinating, tagging, organizing, and collaborating on documents across the organization; leveraging machine language to discover content that would otherwise be missed via Boolean; and incorporating artificial intelligence to do predictive analysis and make recommendations based on historical data. These systems must continue without interruption and meet Sponsor approved timelines for new development activities. The team will comply with the Sponsor's Lean Agile methodology, participate in all Lean Agile scrums, sprints and grooming sessions, and with Sponsor oversite, manage the progress of Commercial-Off-The-Shelf (COTS) product integration and development efforts. They will provide for O&M of existing system capabilities for enabling search against unstructured data sets; federating searches across external data sources; coordinating, tagging, organizing, and collaborating on documents across the organization and will provide after-hour support on an on call basis. The team will ensure O&M and software enhancement activities meet Sponsor approved timelines; consult and coordinate appropriately for problem resolution, task scheduling, new resource requirements, and task clarification; and operate in partnership with an integrated team of staff and contractors. They should understand the Sponsor's target cloud environment, such as AWS or Azure, and coordinate and collaborate with Sponsor security, operations, testing, and other teams to provide system information and technical support. The team will comply with the Sponsor's Risk Management (i.e., cyber security) Framework to ensure that the program addresses and mitigates vulnerabilities and risks identified throughout the lifecycle of the project; create, manage, and update Jira tickets; and assist in navigating the security accreditation process. They will support the dissemination of products to access-controlled users; develop and deploy web applications and user experiences supporting the dissemination of analytic product; and with Sponsor direction, provide prototype solutions to demonstrate feasibility and potential benefits of various technical solutions such as: establishing a unified backend architecture for the Sponsor's program, or redesigning and modernizing the existing backend infrastructure. The team will implement changes to current applications based on Sponsor requirements and support the Sponsor's representatives in the technical assessment to right-size and scale cloud services to include Government-purchasing, engineering, and architecture related activities as applicable to applications. They will track work requirements and action items to meet program deadlines; deliver development requirements as requested by the Sponsor; use a Sponsor-approved tracking system for issues and problems; and provide applications development and programming support to develop software to implement system-level requirements. The team will implement, at Sponsor direction, changes to the current applications based on changing partner requirements, legislation, and policy and new functionality to system software. They will conduct functionality and performance testing for existing applications; develop applications and modifications to existing Sponsor applications in compliance with the Sponsor's architectural and Authorization and Accreditation (A&A) process; and with Sponsor oversight, engage with end users, stakeholders, and project team members to understand end-user goals and business requirements. The team will create and communicate interaction and UX design decisions in the most appropriate forms (e.g., user stories, wireframes, high-fidelity mockups, etc.) with Sponsor's organization and, with Sponsor oversight, maintain a continuous feedback loop with users and stakeholders for UI/UX decision-making.
