You’ll bring senior technical judgment to architecture and model decisions, partner closely with clients and business stakeholders — including hands-on pre-sales work shaping proposals and solution designs — and define how context engineering, agent harnesses, and fine-tuning practices get embedded into every solution, while reporting into senior AI/technology leadership on strategy and priorities.</p> <ul> <li>AI & ML Solution Architecture: Leading the design, build, and optimization of production AI systems — classical machine learning models, LLM applications, and agentic systems — ensuring scalability, reliability, and cost-efficient inference.</li> <li>Context Engineering: Defining and standardizing context engineering practices — prompt and system design, RAG architectures, vector stores, memory management, and tool/function calling — so models receive the right information at the right time.</li> <li>Harness Engineering: Directing the build of robust agent harnesses — orchestration layers, evaluation frameworks, guardrails, and observability — that make LLM systems reliable, safe, and measurable in production.</li> <li>Fine-Tuning Pipelines: Leading the design and operation of fine-tuning and model adaptation pipelines — training data curation, supervised fine-tuning, evaluation, and deployment — to specialize models for client use cases.</li> <li>Platform Stack: Architecting and deploying solutions on Google Gemini Enterprise and Vertex AI as the primary stack, applying working knowledge of Microsoft AI Foundry and AWS Bedrock where client contexts require.</li> <li>Team Leadership: Managing, mentoring, and developing a team of AI & ML engineers; setting technical standards and fostering best practices and knowledge sharing.</li> <li>Pre-Sales & Business Development: Supporting pre-sales activities — scoping engagements, building demos and proofs of concept, and presenting solution architectures to prospective clients alongside account teams.</li> <li>Machine Learning Modeling: Overseeing the development of classical and modern ML models — predictive modeling, forecasting, recommendation, and deep learning — choosing the right technique for each business problem, LLM or not.</li> <li>Contributing to AI Strategy: Partnering with senior leadership to shape GenAI architecture direction, tooling decisions, and platform roadmap within your area. </li> </ul> <p><strong>What we are looking for </strong></p> <ul> <li>The ideal candidate has a substantial software engineering and AI background with 8+ years of experience, including at least 2–3 years working on LLM architecture, agentic design, and harness & context engineering.</li> <li>Strong expertise in generative AI/LLM engineering — context engineering, agent harnesses, RAG, and agentic coding — and in cloud-native software architecture, with proven production deployments.</li> <li>Master’s degree (or higher) in computer science, software engineering, or a related field.</li> <li>Hands-on command of agentic SDKs (LangGraph/LangChain, Google ADK, Claude Agent SDK), agentic coding tools (Claude Code, Gemini CLI, Cursor), and modern full-stack frameworks (TypeScript/React front ends; Python/Node backends).</li> <li>Experience designing cloud architectures: microservices, serverless, containers/Kubernetes, CI/CD, and infrastructure as code.</li> <li>Solid grasp of AI system design: agents, tool use, evaluation harnesses, guardrails, observability, and LLMOps.</li> <li>Experience with data & context modeling and ingestion/processing pipelines on data lakes and data warehouses, including vector and graph storage strategies (embeddings, knowledge graphs).</li> <li>Deep experience with Google Gemini Enterprise / Vertex AI; basic working knowledge of Microsoft AI Foundry and AWS Bedrock.</li> <li>Experience leading and growing engineering teams, and supporting pre-sales: proposals, demos, and solution scoping with c
