Overview:
Our client, a Fortune 50 Financial Services Firm is seeking a Senior UI/UX Engineer to design and build advanced, productiongrade web interfaces for internal and enterprisefacing AI security platforms and related research and riskanalysis 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 multistage 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 multistep assessment workflows (upload scan reconcile classify)
• Render large, dynamic graphs (hundreds to thousands of nodes) with performanceaware interaction patterns
• Expose epistemic states (factual vs declared vs conceptual) clearly to users
• Support humanintheloop audit workflows , overrides, and immutable decision trails
• Scale from early wireframes to enterprisegrade platforms used by security architects and risk teams

Key Responsibilities

UX & Interaction Design

• Design endtoend workflows for complex AI analysis tools (e.g., 4step 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 TypeScript with modern frontend frameworks
• Implement highperformance graph visualizations (canvas/WebGLbased, not DOMbound)
• Integrate frontend applications with Flask and FastAPIbased backends
• Consume REST and WebSocket APIs for realtime progress updates
• Ensure UI state remains consistent with async backend pipelines
• Design scalable component architectures suitable for enterprise usage

SystemAware 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 TypeScript
• Experience with one or more modern frontend frameworks (React, Next.js, Remix, SvelteKit, etc.)
• Strong CSS and layout fundamentals for complex dashboards
• Experience building datadense, interactionheavy UIs

Backend Integration

• Comfortable integrating with Flask and FastAPI backends
• Experience consuming REST APIs and WebSockets
• Understanding of async workflows and longrunning backend jobs

Visualization & Performance

• Experience with graph or diagram rendering libraries (e.g., Cytoscape.js, React Flow, D3, Sigma.js, or similar)
• Understanding of when to use Canvas/WebGL vs DOM
• Experience handling UI performance constraints at scale (virtualization, progressive loading, aggregation)

UX & Design Skills

• Proven experience designing technical products (developer tools, internal platforms, security tooling, AI systems)
• Ability to reason about user cognition when presented with uncertainty, conflict, or incomplete data
• Strong visual hierarchy and informationarchitecture skills
• Comfort designing for expert users , not just casual users
• Ability to balance clarity with accuracy-no handwavy UX

Nice to Have (But Not Required)

• Experience designing interfaces for:
  • Security tooling
  • Compliance or audit systems
  • AI/ML platforms
• Familiarity with:
  • Graph theory concepts
  • AI pipelines (RAG, agents, embeddings)
  • IaC or cloud architecture diagrams
• Background as a frontend engineer who evolved into UX, or a UX designer who codes deeply

Upon completion of waiting period consultants are eligible for:

• Medical and Prescription Drug Plans
• Dental Plan
• Vision Plan
• Health Savings Account
• Health Flexible Spending Account
• Dependent Care Flexible Spending Account
• Supplemental Life Insurance
• Short Term and Long Term Disability Insurance
• Business Travel Insurance
• 401(k), Plus Match
• Weekly Pay
