Senior Consultant - AI Tech Transformation - TC - FS

The opportunity

We are seeking a Senior Consultant specializing in generative AI to help design and build GenAI solutions for our clients. This is a hands‑on, delivery‑focused role: you will build key solution components, support the overall architecture, and work directly with client teams to move solutions into production. It is an excellent role for a strong engineer growing into architecture and client‑facing leadership.

Your key responsibilities

Hands‑On Delivery

• Build and deliver GenAI solution components: RAG pipelines, prompt orchestration, tool‑calling integrations, and APIs.
• Support the solution architecture and contribute to design decisions within your components.
• Ensure your components are reliable, secure, performant, and cost‑aware.
• Contribute to delivery execution: implementation, testing, debugging, and resolution of technical issues.
• Apply engineering standards, reusable frameworks, and accelerators in your work.
• Take ownership of the quality and timeliness of your deliverables.

Technical Contribution

• Implement generative AI solutions using LLMs, RAG pipelines, prompt orchestration, and agentic workflows.
• Build components for insurance use cases (claims intake automation, submission triage, document intelligence, underwriting copilots, policy Q&A, contact‑center copilots).
• Implement and tune RAG: chunking, embeddings, vector stores, retrieval tuning, and grounding to reduce hallucination.
• Develop multi‑agent and tool‑calling workflows for insurance processes.
• Apply LLMOps and quality practices: prompt engineering, evaluation, guardrails, monitoring, and cost/latency optimization.
• Apply responsible AI practices: hallucination controls, PII handling, and compliance‑aware handling of sensitive data.
• Support integration with core insurance platforms (Guidewire, Duck Creek, Sapiens) and enterprise data/content systems.
• Work directly with client teams to deliver solutions and resolve technical questions.
• Explain technical decisions, tradeoffs, and progress clearly to project team members and stakeholders.
• Prepare and support demos and technical walkthroughs.
• Collaborate across engineering, data, and business stakeholders during delivery.
• Support and guide junior consultants where needed.

Skills and attributes for success

• Strong hands‑on engineering skills and eagerness to grow into architecture.
• A delivery mindset with attention to quality and detail.
• Clear communication and a collaborative, client‑facing attitude.
• Curiosity and a fast learning pace in a rapidly evolving field.

To qualify for the role;

• Bachelor's or Master's in Computer Science, Engineering, or a related field.
• Experience in technology delivering software or data solutions, including hands‑on work on at least two GenAI or AI/ML projects (with ~1 year of GenAI experience).
• Hands‑on experience with LLMs (OpenAI, Anthropic, Google, or open‑weight models like Llama/Mistral) and orchestration frameworks (LangChain, LlamaIndex, Semantic Kernel, or equivalent).
• Practical experience with RAG, embeddings, and vector databases (Pinecone, Weaviate, pgvector, Azure AI Search).
• Familiarity with agentic architectures, function/tool calling, and structured outputs.
• Prompt engineering and evaluation experience, with awareness of guardrails and safety.
• Experience with at least one cloud GenAI platform (Azure OpenAI, AWS Bedrock, Google Vertex AI).
• Solid programming skills and understanding of API design and integration patterns.
• Awareness of responsible AI and secure handling of sensitive data.
• Good communication skills, able to explain technical work clearly.

The following will be an advantage;

• Exposure to GenAI or AI/ML solutions in insurance or financial services.
• Familiarity with insurance document workflows (ACORD forms, loss runs, policy documents).
• Experience contributing to solutions moving from proof‑of‑concept toward production.
• Relevant cloud or AI certifications.
