Role Summary

World Wide Technology is looking for a deeply technical Enterprise Architect who will own the delivery of AI projects end to end from the silicon and data center design that underpins AI workloads, through the software and MLOps stack, to the governance frameworks that make AI trustworthy and defensible at scale.

This is a technical hardware-and-software architect role, not a strategy-only position. The successful candidate operates comfortably across GPU infrastructure, high-performance networking, model training and inference pipelines, and the AI risk/governance disciplines increasingly demanded by regulators and enterprise boards.

The Enterprise Architect will lead technical delivery teams for client engagements, acting as the single point of technical accountability from design through to go-live, while mentoring delivery teams and shaping WWT's broader AI point of view.

Key Responsibilities

Own end-to-end technical delivery of AI/ML engagements: architecture definition, design authority, build oversight, and go-live validation.
Host and chair Architecture Review Board (ARB) and Technical Design Authority (TDA) sessions for AI engagements, owning governance gates, decision records, and design sign-off.
Architect AI infrastructure spanning GPU/accelerator compute, high-performance interconnects ,parallel/high-throughput storage, and orchestration
Design the AI software stack: training and fine-tuning pipelines, distributed training frameworks, inference/serving platforms, MLOps/LLMOps tooling, vector databases, and retrieval-augmented generation (RAG) and agentic architectures.
Define and AI governance frameworks covering model risk management, responsible AI, data lineage, bias/fairness testing, explainability, and regulatory alignment (EU AI Act, NIST AI RMF, ISO/IEC 42001).
Act as trusted technical advisor to client CTOs, CIOs and Heads of Data/AI on platform strategy, build-vs-buy decisions, and AI operating model design.
Lead technical workshops, architecture design sessions, and proof-of-concept builds with cross-functional engineering, data science, and security teams.
Serve as the technical escalation point for delivery teams; unblock design and implementation issues under time pressure.
Mentor other architects and engineers on AI systems design, uplifting AI depth across the practice.
Partner with sales and pre-sales to scope AI solutions, size infrastructure, and validate technical feasibility of proposed architectures.
Define automation, orchestration, and observability standards across the AI stack, from GPU cluster provisioning through to model monitoring in production.
Architect integration points connecting AI platforms to existing enterprise networks, third-party systems, and external or service-provider-hosted environments (e.g. colocation, managed GPU-as-a-service, external inference endpoints).
Track the fast-moving AI landscape — new model architectures, silicon, frameworks and regulation — and translate relevant developments into WWT's delivery methodology and client recommendations.

Required Technical Skills & Experience

Experience Baseline

10+ years in enterprise architecture, infrastructure engineering, or platform engineering roles.
5+ years focused specifically on AI/ML systems design and delivery, including at least 2 years working with generative AI/LLM workloads.
Demonstrated track record leading technical delivery (not just advisory) on enterprise-scale AI or HPC infrastructure programmes.

AI Hardware & Data Center Infrastructure

GPU/accelerator architectures: NVIDIA / AMD, including multi-node scale-out design.
Accelerator interconnects: NVLink, NVSwitch
High-performance networking: InfiniBand and RoCEv2 fabric design, 400G/800G Ethernet, rail-optimized topologies for AI clusters.
Data center facilities: power density, liquid cooling, and rack-level design considerations specific to AI compute.
Storage: parallel and high-throughput file systems (e.g. Everpure, WEKA, VAST, NetApp) sized for training and checkpointing workloads.

AI Software, MLOps & Generative AI

Orchestration & containers: Kubernetes, Docker, Slurm, Run:ai or equivalent GPU scheduling platforms.
ML frameworks: PyTorch and TensorFlow at a working, hands-on level.
Distributed training: Horovod, DeepSpeed, Megatron-LM, or equivalent multi-node training frameworks.
Inference & serving: NVIDIA Triton, vLLM, TensorRT-LLM, or equivalent high-throughput serving platforms.
MLOps/LLMOps: Kubeflow, MLflow, and at least one hyperscaler ML platform (SageMaker, Azure ML, or Vertex AI).
Generative AI: LLM fine-tuning (LoRA/QLoRA), RAG architecture design, vector databases (Pinecone, Milvus, Weaviate), and agentic frameworks (LangChain, LangGraph, Semantic Kernel).
