Senior UI/UX Engineer

Senior UI/UX Engineer#26-11400 Chandler, AZ All On-site Job Description We are 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: o Confidence scoring and provenance o Conflict surfacing (MME / UME) o Human override & justification flows o 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 high performance graph visualizations (canvas/WebGL based, not DOM bound)
• Integrate frontend applications with Flask and FastAPI based backends
• Consume REST and WebSocket 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: o Evidence hierarchy (code > docs > diagrams) o Deterministic classification rules o Epistemic uncertainty
• Surface contradictions and ambiguity explicitly, instead of hiding them behind "happy path" UX Collaboration
• Collaborate closely with: o Backend engineers (Flask / FastAPI) o AI/ML engineers o 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, .js, Remix, SvelteKit, etc.)
• Strong CSS and layout fundamentals for complex dashboards
• Experience building data dense, interaction heavy UIs Backend Integration
• Comfortable integrating with Flask and FastAPI backends
• Experience consuming REST APIs and WebSockets
• Understanding of async workflows and long running 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 information architecture skills
• Comfort designing for expert users, not just casual users
• Ability to balance clarity with accuracy—no hand wavy UX ________________________________________ Nice to Have (But Not Required)
• Experience designing interfaces for: o Security tooling o Compliance or audit systems o AI/ML platforms
• Familiarity with: o Graph theory concepts o AI pipelines (RAG, agents, embeddings) o IaC or cloud architecture diagrams
• Background as a frontend engineer who evolved into UX, or a UX designer who codes deeply
