Role Summary
The UX Engineer will define and deliver intuitive, coherent, and technically credible user
experiences across the AI & Applications team’s internal and external product portfolio. The
role will shape how users discover, provision, operate, optimize, and troubleshoot AI
infrastructure and AI-powered services through products such as the AI Cloud Portal, Global
Operations Console, Bare Metal as a Service, Kubernetes as a Service, and future X-as-a-Service
offerings.
This role sits at the intersection of user experience design, front-end engineering, product
thinking, and AI-platform understanding. The UX Engineer will translate complex infrastructure
and AI capabilities—including GPU capacity, bare-metal provisioning, Kubernetes clusters,
workload scheduling, benchmark results, model recipes, inference services, Model-to-Grid
optimization, and agentic operations—into clear workflows, understandable interfaces, and
actionable experiences for customers, developers, AI researchers, support teams, operators,
and internal delivery teams.
A central focus will be making sophisticated AI-factory capabilities usable. The UX Engineer will
help users understand and act on model-to-grid recommendations, scheduler decisions,
workload placement, cluster health, benchmark outcomes, capacity availability, performance
bottlenecks, inference cost, energy or power signals, and agent-generated operational insights.
The role will ensure that advanced automation remains transparent, controllable, auditable,
and trustworthy—particularly where agentic systems recommend or execute actions.
The UX Engineer will report to the Head of AI & Applications, working closely with other AI
engineers, DevOps and scheduler engineers, inference and optimization engineers, platform,
infrastructure, security, global operations, and customer-facing teams. The role will create a
scalable design system and product experience that supports both immediate platform needs
and future AI-factory and XaaS product expansion.
Key Responsibilities
- Own end-to-end UX design and front-end experience quality for the AI Cloud Portal,
Global Operations Console, Bare Metal as a Service, Kubernetes as a Service, and future
XaaS products.
- Conduct user discovery and workflow analysis with key personas, including AI
researchers, ML engineers, application developers, cloud administrators, tenant
administrators, infrastructure operators, support engineers, data-centre teams, and
external customers.
- Translate product requirements, user needs, operational workflows, technical
constraints, and system telemetry into user journeys, information architectures,
wireframes, prototypes, interaction patterns, and production-ready interfaces.
- Design self-service experiences for discovering, requesting, provisioning, configuring,
accessing, monitoring, scaling, updating, and decommissioning bare-metal GPU capacity
and Kubernetes environments.
- Design clear workflows for GPU and AI workload management, including job submission,
job templates, model and workload recipes, queue selection, quota visibility, priority
requests, capacity reservations, workload status, failures, retries, and support
escalation.
- Create usable interface patterns that explain proprietary scheduler decisions, including
why a job is queued, admitted, deferred, placed on a particular topology, pre-empted,
rescheduled, or unable to run.
- Design Model-to-Grid experiences that help users and operators understand the
relationship between model or workload requirements, benchmark results, GPU
resources, network topology, storage, capacity, power, thermal conditions, and
scheduling outcomes.
- Create user-facing workflows for selecting and applying validated model, training, fine-tuning, and inference recipes based on workload goals such as latency, throughput,
accuracy, cost, energy efficiency, GPU availability, or time-to-results.
- Design intuitive benchmarking experiences, including benchmark configuration,
execution tracking, result exploration, comparison of baselines and variants,
reproducibility metadata, bottleneck identification, and actionable optimization
recommendations.
- Shape the Global Operations Console experience for monitoring and managing fleet-level AI-factory operations, including cluster health, capacity, workload demand,
infrastructure events, service status, scheduler health, resource utilization, maintenance
activities, and operational incidents.
- Make complex infrastructure status and telemetry actionable through dashboards, drill-down views, alerts, guided troubleshooting, root-cause context, recommended actions,
and role-appropriate escalation paths.
Design agentic application experiences that clearly distinguish between agent
observations, recommendations, planned actions, approved actions, completed actions,
failures, and human intervention points.
- Create safe and trustworthy human-in-the-loop workflows for agentic operations,
including approval queues, permission scopes, action previews, confidence or evidence
views, audit trails, rollback options, and incident escalation.
- Design user experiences for AI platform identity, access, tenancy, quotas, approvals,
notifications, billing or consumption visibility, support, and administrative controls in
partnership with Security and platform teams.
- Develop and maintain a scalable design system, component library, interaction
standards, accessibility guidelines, content patterns, and visual language suitable for
cloud, AI-platform, and operations-console products.
- Implement high-quality front-end experiences or work closely with front-end engineers
to ensure designs are technically feasible, performant, responsive, accessible, and
consistently implemented.
- Partner with the Product Manager / TPM / Release Manager to define user-facing
product requirements, UX acceptance criteria, phased release plans, usability validation,
release notes, product documentation, and adoption measures.
- Work with AI, DevOps, Platform, SDI, Security, and operations teams to ensure
interfaces accurately represent system state, operational constraints, permissions, data
freshness, risk level, and action consequences.
- Define and analyze UX metrics, customer feedback, product analytics, workflow
completion, feature adoption, support trends, task duration, error rates, and usability
findings; use them to prioritize iterative improvements.
- Champion a product-led, user-centered approach across technical teams by making user
workflows, usability risks, and customer outcomes visible early in product definition and
delivery.
