What we look for We are seeking tech professionals, with good knowledge of DLT and digital assets processes and products, to join our growing team to build our business and support our clients build more resilient, efficient and profitable businesses. We are looking for experienced and enthusiastic team members to drive delivery of client engagements and to develop new solutions and market insights to drive revenue growth. ## Description 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., * 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. Collaboration & Communication * 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. ## Related Videos - [AI PowerPlay: Building High-Impact Teams & Transformative Solutions](https://www.wearedevelopers.com/videos/1005-ai-powerplay-building-high-impact-teams-transformative-solutions) - [API Design - Getting Started](https://www.wearedevelopers.com/videos/33-api-design-getting-started) - [From Messy Queries to Scalable Systems - How Data Engineering actually works](https://www.wearedevelopers.com/videos/100203-from-messy-queries-to-scalable-systems-how-data-engineering-actually-works) - [AI in Leadership: How Technology is Reshaping Executive Roles](https://www.wearedevelopers.com/videos/1705-ai-in-leadership-how-technology-is-reshaping-executive-roles) - [Rest API Antipatterns](https://www.wearedevelopers.com/videos/100208-rest-api-antipatterns) - [The Data Mesh as the end of the Datalake as we know it](https://www.wearedevelopers.com/videos/156-the-data-mesh-as-the-end-of-the-datalake-as-we-know-it) ## Related Articles - [Navigating the AI Shift](https://www.wearedevelopers.com/magazine/629-navigating-the-ai-shift) - [How to Become an AI Engineer](https://www.wearedevelopers.com/magazine/331-how-to-become-an-ai-engineer) - [Got AI ideas but no money?
