Job Description & Summary
At PwC, we help clients build trust and reinvent so they can turn complexity into competitive advantage. We’re a tech-forward, people-empowered network with more than 370,000 people in 149 countries. Across audit and assurance, tax and legal, deals and consulting we help build, accelerate and sustain momentum.
The role:
As an AI Architect, you will design and guide production-ready Generative AI solutions for clients, from early discovery through implementation. This role combines hands-on architecture, technical leadership, and client collaboration. You will help teams choose where Generative AI adds value, build secure and scalable solutions, and measure their quality and cost in production.
Your responsibilities will include:
Solution Architecture & Delivery
Lead the architecture and delivery of Generative AI solutions, guiding development teams on relevant tools, frameworks, and platforms.
Translate business requirements into robust application, service, and target-state architectures, including reusable RAG, agent orchestration, prompt, and evaluation patterns.
Own scalability, performance, latency, observability, security, and cost optimisation across AI solutions.
Lead technical design and code reviews and guide delivery against client needs and quality standards.
Define the right adaptation approach for each use case—prompting, RAG, fine-tuning, or distillation—including when Generative AI is not appropriate.
AI Quality, Security & Operations
Own evaluation strategy, including golden datasets, offline and online evaluation, human-calibrated LLM-as-judge, and CI regression testing.
Set retrieval quality standards for chunking, hybrid search, reranking, query rewriting, and permission-aware retrieval, using measured recall and precision.
Define AI security, privacy, Responsible AI, and governance controls, including prompt injection, data exfiltration, jailbreak, sandboxing, least-privilege identity, and supply-chain risks.
Own solution economics through model routing, caching, batching, capacity planning, and defensible cost-per-transaction estimates.
Support enterprise architecture standards and help assess technology solutions.
Leadership, Clients & Practice
Supervise vendor developers and mentor engineers and junior architects.
Support business development by identifying and researching opportunities with new and existing clients.
Improve internal design and development practices and maintain documentation.
Build internal relationships, strengthen the firm's reputation, and develop your skills in line with company and team priorities.
Take on additional responsibilities relevant to the role and agreed with your manager.
What You'll Bring
Experience
5+ years of experience in agile product delivery.
Hands-on experience designing and delivering production software solutions at scale.
Demonstrated expertise in Generative AI solution architecture.
You have personally delivered at least one Generative AI system to production and can explain its architecture, failure modes, operating costs, and lessons learned.
Education & Certifications
Bachelor's or Master's degree in Computer Science or Engineering, or equivalent practical experience.
Relevant Microsoft Azure certification, such as Azure Solutions Architect Expert or Azure Developer Associate, is preferred.
Technical Skills & Specialized Knowledge
Strong hands-on experience with Generative AI architecture is essential. Experience across several relevant technologies is expected; expertise in every named tool is not required.
