• Design, develop, and maintain Android-first and cross-platform mobile applications (with React Native as the primary framework). • Ensure apps comply with DoD cybersecurity and mobile device management (MDM) policies. • Collaborate with UI/UX designers and stakeholders to deliver responsive and intuitive user experiences. • Conduct code reviews, implement unit and integration tests, and support automated mobile testing as part of CI/CD pipelines. • Troubleshoot, debug, and resolve defects across multiple device types and OS versions.

• Kernel-mode and user-mode code development: write code that transforms messages, processes data, interfaces with components in different languages, and interacts with Web APIs. • Diagnose and triage customer issues: analyze logs, crash dumps, and diagnostic data to identify root causes and drive timely resolutions. • Cross-functional collaboration: work closely with customer support, sales teams, product management, and engineering teams to resolve customer issues, improve product quality, and ensure seamless integration across components. • Optimization and profiling: use profiling tools to optimize code performance. • Test and maintain code quality: write unit and integration tests, adhering to consistent coding styles and architectural guidelines.

• Interpret and analyze vulnerability results from tools such as Tenable Nessus to assess risk, identify remediation paths, and drive POA&Ms to closure. • Utilize deep technical skills to log into affected systems and directly address complex vulnerabilities across Red Hat Enterprise Linux and Windows Server workloads. • Coordinate closely with system owners, engineering teams, and cloud platform teams to implement mitigations with minimal turnaround time. • Apply strong understanding of cloud security best practices across AWS and Azure environments. • Use comprehensive knowledge of operating system internals to resolve non-standard or configuration-based vulnerabilities. • Develop, track, and validate remediation plans for findings that require configuration changes, service adjustments, or architectural modifications. • Monitor remediation progress, identify blockers, and ensure accurate and timely documentation in accordance with program requirements. • Provide technical support and troubleshooting related to vulnerability remediation activities. • Work with engineering staff to validate fixes, retest findings, and ensure vulnerabilities do not reoccur. • Participate in continuous improvement of vulnerability management processes, reporting, and operational readiness. • Work closely with the program’s Information System Security Officer (ISSO) to coordinate vulnerability remediation activities, POA&M management, and continuous monitoring. • Align vulnerability remediation efforts with RMF and ATO requirements in coordination with the ISSO. • Serve as a backup to the ISSO, providing continuity of security and compliance operations as needed. • Support preparation and updates of security documentation inputs, including POA&M updates and assessment artifacts, related to vulnerability findings.

• Develop benchmarks, end to end customer applications running at scale, instrumented for performance measurements, tracking, sampling, to measure and optimize performance of important applications and services; • Construct carefully designed experiments to analyze, study and develop critical insights into performance bottlenecks, dependencies, from an end to end perspective; • Develop ideas on how to improve the end to end system performance and usability by driving changes in the HW or SW (or both). • Collaborate with AI researchers, developers, and application service providers to understand internal developer and external customer pain points, requirements, project future needs and share best practice. • Develop the necessary modeling framework and the TCO (total cost of ownership) analysis to enable efficient exploration and sweep of the architecture and design space • Develop the methodology needed to drive the engineering analysis to Inform the architecture, design and roadmap of DGX Cloud
