Meaghan Cox // HCI Researcher & Designer
Design Leadership for Complex Platforms
I work on large, fragmented systems—making them legible technically, operationally, visually, and cognitively—so organizations can scale without losing coherence.
Bridging architectural complexity and human cognition to build intuitive, high-performance systems for deep-tech platforms.
As a systems practitioner, I apply HCI principles and rigorous research methodology to intricate digital infrastructures. My focus is on the cognitive ergonomics of complex interfaces, ensuring that platform scalability never comes at the cost of human usability.

Selected Works
PLATFORM ARCHITECTURE // COUPA SYSTEM
TRANSFORMING FRAGMENTED DELIVERY INTO A UNIFIED DESIGN INFRASTRUCTURE.
Coupa — Design System as Platform Infrastructure
In a period of high-growth fragmentation, I architected the design infrastructure that unified a multi-application technical suite. By defining the underlying token and component architecture, I translated abstract standards into engineering realities, creating a coherent platform landscape across ~30 independent product surfaces.
- Established the tokenized bedrock for platform-wide consistency.
- Successfully translated design standards into functional engineering frameworks.
- Reduced surface fragmentation through centralized UI governance.
- Modernized the digital estate via programmatic component adoption.
OPERATIONAL SYSTEMS // DELIVERY INFRASTRUCTURE
REDEFINING DESIGN AS A MANAGED TECHNICAL PRODUCT WITH MEASURABLE THROUGHPUT.
Coupa — DS Operating System
This initiative converted an aspirational design library into a managed technical product. By building the operational machinery for component definition and delivery, I formalized the handoff process into a measurable workstream, significantly reducing organizational risk and increasing programmatic throughput across the enterprise.
- Created blueprint-style frameworks to bridge design and engineering.
- Productized design system initiatives into strategic workstreams.
- Built a multi-layer Notion ecosystem for delivery tracking and QA.
- Architected a scalable knowledge base for foundational design standards.
AI INTEGRATION // COGNITIVE ERGONOMICS
DEFINING HUMAN-CENTERED EXPERIENCE MODELS FOR DISTRIBUTED AI ADOPTION.
Coupa — AI Product Integration
I led the platform-level integration of early AI capabilities, focusing on the cognitive ergonomics of high-density interfaces. By defining the experience models and reusable interaction patterns, I enabled the adoption of guided AI UX across a complex, multi-application ecosystem without sacrificing platform integrity.
- Defined chatbot experience models within a complex platform context.
- Standardized interaction patterns for cross-surface AI adoption.
- Developed reusable UI components for AI-driven workflows.
- Ensured data trustworthiness through rigorous experience modeling.
ORGANIZATIONAL ENABLEMENT // CAPABILITY REPAIR
SYSTEMIC INTERVENTION TO HEAL FRAGMENTED DELIVERY IN LOW-MATURITY ENVIRONMENTS.
Coupa — Leadership & Enablement
Operating as a senior multiplier in a high-demand environment, I drove the repair of organizational design processes. By coaching designers and partnering with executive leadership, I established the interaction standards and delivery workflows necessary to sustain high-performance platform quality.
- Upskilled the design team through rigorous interaction standard training.
- Healed organizational friction by realigning design with engineering workflows.
- Used research-driven R&D to pitch and move strategic platform initiatives.
- Intervened in platform modeling to preserve long-term systemic quality.
PLATFORM DIAGNOSTIC // STRATEGIC AUDIT
QUANTIFYING FRAGMENTATION INTO A DECISION-GRADE CASE FOR REPAIR.
Coupa — Platform Audit & Standardization
This strategic audit reframed visual fragmentation as an operational cost. By conducting a high-fidelity diagnostic of ~400 surface pages, I quantified inconsistency into decision-grade evidence for executive investment, shifting the organizational focus from tactical 'style' to systemic interaction quality.
- Audited ~400 platform surfaces to identify core fragmentation risks.
- Translated technical variants into decision-grade executive evidence.
- Secured buy-in for 'System, Not Style' as a platform performance metric.
- Diagnosed root-cause process gaps to inform long-term repair.
OBSERVABILITY SYSTEMS // ROLE-BASED ARCHITECTURE
ABSTRACTING BACKEND COMPLEXITY INTO HUMAN-LEGIBLE STATE MODELS.
Llamasoft — Distributed Job Orchestration & Execution Monitoring
I transformed backend execution monitoring into a human-legible observability surface for enterprise troubleshooters. Faced with a complex cloud transition, I abstracted technical server statuses into durable conceptual states, creating a role-based IA that prioritizes high-accuracy decision making.
- Abstracted backend complexity into 20+ human-legible system states.
- Redesigned the IA for Internal Operators and External user clarity.
- Built high-fidelity monitoring surfaces with live telemetry inspection.
- Established the cloud-transition patterns for future enterprise applications.
