Collaborating with engineers, architects, and mission stakeholders, you will deliver innovative tools that enhance decision-making and operational effectiveness in support of national security objectives. What You Will Do : + Serves as the lead frontend/fullu2011stack engineer responsible for developing the FBI adjudication platformu2019s analystu2011facing interface, enabling analysts to review AI outputs, explore entities, assess anomalies, evaluate SEADu20114 scoring rationales, and generate adjudication memos. + Designs intuitive, performant, secure, and accessible UI components supporting longu2011document review, multiu2011panel comparisons, risk visualization, humanu2011AI review workflows, and structured memo generation. + Implements fullu2011stack integrations between UI components, backend APIs, LLM inference endpoints, retrieval services, scoring engines, and workflow orchestration pipelines. + Ensures frontend components comply with FedRAMP High, RMF, NIST 800u201153, and FBI ATO requirements including session integrity, RBAC, secure rendering, and audit logging. UI/UX Engineering for Analyst Workflows + Design and implement UI components for evidence review including longu2011document navigation, multiu2011page PDF rendering, inu2011line annotations, bookmarks, and sideu2011byu2011side comparisons. + Develop interfaces for entity extraction panels showing extracted entities, risk flags, crossu2011references, and SEADu20114 guideline relationships. + Build a memou2011builder UI that integrates AIu2011generated drafts with human edits, supports structured adjudication templates, source citations, formatting tools, and approval workflows. + Implement dashboards showing risk indicators, timeline reconstructions, anomaly summaries, continuousu2011vetting alerts, and adjudication scoring breakdowns. Frontend Engineering (React / Angular / TypeScript) + Develop frontend applications using React, Angular, or Vue with strong TypeScript patterns, modular component design, and maintainable stateu2011management solutions (Redux, NGXS, Zustand, MobX). + Implement secure UI behaviors including RBACu2011aware rendering, sanitized inputs, contentu2011security policies, strict routing guards, and safe thirdu2011party component usage. + Optimize rendering pipelines supporting large datasets, long files, and dynamic case workloads using virtualization, lazy loading, and performance tuning. + Build reusable design systems, theming layers, and accessibilityu2011compliant components (Section 508). Fullu2011Stack Development & API Integration + Integrate UI components with backend APIs providing document ingestion, entity metadata, LLM results, retrieval outputs, scoring engines, and memou2011generation workflows. + Implement clientu2011side API wrappers, schema validation, request batching, and offlineu2011safe patterns to improve robustness and reliability. + Support eventu2011driven features using WebSockets or streaming APIs to show live processing updates, workflow routing events, or LLM inference progress. + Collaborate with backend engineers to cou2011design schemas that guarantee consistency, traceability, and auditu2011friendly communication across API boundaries. Data Visualization, Evidence Representation & Risk Display + Build interactive charts, timelines, relationship graphs, and risku2011factor matrices visualizing SEADu20114 scoring, anomalies, evidence linkages, and adjudication logic. + Develop UI components that present AIu2011generated outputsu2014including structured reasoning strings, classification labels, and modelu2011confidence indicatorsu2014in clear and interpretable formats. + Implement comparative displays allowing analysts to reconcile model outputs with source evidence, improving trust, transparency, and humanu2011AI synergy. Security, Compliance & Logging (FedRAMP High / RMF / ATO) + Implement secure UI development practices including sanitized rendering, CSP headers, strict input validation, and secure embedding of documents and interactive content. + Integrate clientu2011side logging and auditu2011event capture ensuring adjudicator actionsu2014reviews, overrides, memo edits, evidence expansionsu2014are captured for ATO compliance. + Ensure compliance with FedRAMP High, RMF, encryptionu2011inu2011transit, session protection, idle timeouts, and controlled display of sensitive information. + Collaborate with Security Engineers to provide UIu2011specific artifacts for SSPs, controlu2011implementation statements, and audit requirements. Performance Optimization & Reliability + Optimize UI bundles using code splitting, lazy loading, caching strategies, and GPUu2011accelerated rendering when applicable. + Implement diagnostics for clientu2011side telemetry such as component load times, rendering bottlenecks, network degradation, and useru2011behavior traces. + Support automated UI testing using Jest, Cypress, or Playwright, integrating tests into CI/CD pipelines for stable and secure deployments. Collaboration, Leadership & Mission Enablement + Collaborate with AI/ML engineers to safely integrate model outputs into UI workflows, ensuring clarity, accuracy, and missionu2011aligned interactions. + Work closely with UX designers, policy SMEs, and adjudicators to map operational workflows into intuitive UI flows that improve review throughput and decision consistency. + Participate in architecture reviews, sprint ceremonies, design workshops, and mission technical exchanges. + Mentor junior frontend/fullu2011stack engineers in secure UI development, design patterns, observability, accessibility, and federal compliance practices. What You Will Need : + An ACTIVE and MAINTAINED
