** Overview:*
* Our client, a Fortune 50 Financial Services Firm is seeking a  
** Senior UI/UX Engineer
** to design and build advanced, production‑grade web interfaces for internal and enterprise‑facing AI security platforms and related research and risk‑analysis systems.

This role sits at the intersection of  
** UX design, frontend engineering, and AI system observability** . You will be responsible for translating complex backend reasoning, evidence graphs, and multi‑stage AI workflows into  
** clear, intuitive, and scalable user experiences*
* -without oversimplifying the underlying technical truth.

The ideal candidate is not only a designer, but a  
** systems thinker
** who understands how modern AI pipelines, APIs, and security architectures work, and who can design interfaces that  _faithfully represent reality rather than aspirational diagrams_ .

** What You'll Build:*
* You will design and implement web applications that:

+ Visualize  
** AI system architectures
** derived from real code, IaC, and documentation

+ Present  
** multi‑step assessment workflows**  (upload → scan → reconcile → classify)

+ Render  
** large, dynamic graphs**  (hundreds to thousands of nodes) with performance‑aware interaction patterns

+ Expose  
** epistemic states**  (factual vs declared vs conceptual) clearly to users

+ Support  
** human‑in‑the‑loop audit workflows** , overrides, and immutable decision trails

+ Scale from early wireframes to enterprise‑grade platforms used by security architects and risk teams

** Key Responsibilities*
* ** UX & Interaction Design*
* + Design end‑to‑end workflows for complex AI analysis tools (e.g., 4‑step wizard flows, async scan progress, review & reconciliation stages)

+ Translate abstract system concepts (evidence confidence, conflicts, shadow AI, governing patterns) into  
** clear visual metaphors*
* + Define UI patterns for:

+ Confidence scoring and provenance

+ Conflict surfacing (MME / UME)

+ Human override & justification flows

+ Evidence tracing from UI → source code

+ Create wireframes, interaction specs, and component behavior definitions that engineers can directly implement

** Frontend Engineering*
* + Build production UIs using  
** Type Script
* * with modern frontend frameworks

+ Implement  
** high‑performance graph visualizations**  (canvas/WebGL‑based, not DOM‑bound)

+ Integrate frontend applications with  
** Flask‑ and FastAPI‑based backends*
* + Consume REST and Web Socket APIs for real‑time progress updates

+ Ensure UI state remains consistent with async backend pipelines

+ Design scalable component architectures suitable for enterprise usage

** System‑Aware UI Design*
* + Design interfaces that  
** do not lie
** about system state or capability

+ Respect constraints such as:

+ Evidence hierarchy (code  docs  diagrams)

+ Deterministic classification rules

+ Epistemic uncertainty

+ Surface contradictions and ambiguity  _explicitly_ , instead of hiding them behind "happy path" UX

** Collaboration*
* + Collaborate closely with:

+ Backend engineers (Flask / FastAPI)

+ AI/ML engineers

+ Security architects and threat modelers

+ Iterate quickly from wireframes to production while preserving design intent

+ Participate in product architecture discussions-not just visual styling reviews

** Required Technical Skills*
* ** Frontend & UI*
* + Strong experience with  
** Type Script*
* +

Experience with one or more modern frontend frameworks (React, Next.js, Remix, Svelte Kit, etc.)

+ Strong CSS and layout fundamentals for complex dashboards

+ Experience building  
** data‑dense, interaction‑heavy…
