Role Title: AI Consulting –Sr. AI Architect & Client Partner, Vice President

Location: London, United Kingdom (Flexible hybrid working)

Employment Type: Permanent

Summary of the role:

Enterprises are past GenAI experimentation. They now demand production systems with measurable ROI, governance, and scale, and most stall in the gap between an impressive pilot and a system that survives production. EXL lives in that gap. We are accountable for outcomes on our clients’ data, in their environment, against their SLAs. This role is the senior technical authority who makes that real. You convert ambitious, under-specified client mandates into secure, production-grade Generative and Agentic AI systems, and you turn each engagement into reusable IP that compounds EXL’s delivery leverage and pipeline.

The senior technical relationship with client executives, and the technical shaping of the deals that fund the work.

End-to-end technical vision and delivery for enterprise GenAI and Agentic AI programs across a portfolio of clients focused on delivering value / outcomes to the clients.

The technical standard for the practice: reference architectures, reusable accelerators, and the governance and evaluation bar every engagement is held to.

As part of your duties, you will be responsible for:

Partner with sales and practice leaders to shape pursuits, solution complex deals, and influence SOWs, estimates, and delivery approach.

Serve as the senior technical voice in client pursuits and executive conversations, converting technical credibility into won and expanded engagements.

Build reusable accelerators, reference architectures, and IP that lower delivery cost and differentiate EXL in the market.

Identify expansion opportunities within accounts and translate delivered outcomes into follow-on pipeline.

Lead and grow global, multi-disciplinary AI teams, and raise the technical bar across the practice.

Partner with business and technology leaders to define AI roadmaps and implementation strategy.

Mentor architects and engineers, and build a bench of senior technical talent.

Translate complex architectures for executive and non-technical audiences.

Architecture & solution leadership

Own architecture, design, and implementation of enterprise-grade GenAI and Agentic AI solutions from concept to production.

Define scalable reference architectures and design patterns for AI platforms, copilots, and intelligent agents.

Establish architectural standards, reusable components, and best practices across delivery programs.

Design secure, resilient, highly available AI systems at enterprise scale, across structured and unstructured data.

Design and deliver LLM-powered applications: conversational AI, enterprise copilots, knowledge management, and workflow automation.

Architect advanced retrieval using RAG, Agentic RAG, Graph RAG, knowledge-graph, and hybrid approaches.

Design multi-agent systems with modern orchestration and reasoning architectures, including human-in-the-loop and autonomous frameworks.

Define memory, context, planning, tool-use, and reasoning strategies for agentic systems.

Stay technical. Contribute to architecture, critical-path code, design reviews, and the hardest technical problems.

Design APIs, microservices, and cloud-native AI services that underpin enterprise AI ecosystems.

Guide teams on software architecture, performance, scalability, security, and maintainability.

AI governance & LLMOps

Architect governance frameworks for auditability, observability, explainability, and compliance.

Design guardrails for hallucination, prompt injection, toxicity, and model safety.

Establish LLMOps: evaluation pipelines, automated testing, CI/CD, monitoring, and production governance.

Define evaluation frameworks spanning quality, safety, reliability, latency, and business outcomes.

Qualifications and experience we consider to be essential for the role:

10–15 years across software engineering, AI/ML, data science, or enterprise architecture, with a clear trajectory into senior technical leadership.

Proven track record architecting and deploying production-scale AI, from strategy through implementation.

Experience in a consulting, services, or client-facing delivery environment, including supporting pre-sales or solution shaping.

Experience leading globally distributed, multi-disciplinary teams.

Bachelor’s in Computer Science, AI, Engineering, Data Science, or a related field. Master’s preferred.
