What you will be doing You will lead a team of AI & machine learning engineers and managers, driving the design and delivery of production-grade AI solutions — from classical machine learning models to LLM-powered applications — and the pipelines that power them. 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. * 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. * 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. * 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. * 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. * 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. * Team Leadership: Managing, mentoring, and developing a team of AI & ML engineers; setting technical standards and fostering best practices and knowledge sharing. * 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. * 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. * Contributing to AI Strategy: Partnering with senior leadership to shape GenAI architecture direction, tooling decisions, and platform roadmap within your area. What we are looking for * The ideal candidate has a substantial Data Science and machine learning background with 8+ years of experience, including at least 2–3 years working on LLM architecture, agentic design, and harness & context engineering. * Expertise in generative AI/LLM engineering (context engineering, agent harnesses, RAG, and fine-tuning) and in classical machine learning modeling, with proven production deployments. * Master’s degree (or higher) in computer science, engineering, statistics/mathematics, or a related field. * Hands-on command of core machine learning libraries (scikit-learn, XGBoost, etc.), agentic SDKs (LangGraph/LangChain, Google ADK, Claude Agent SDK), and fine-tuning frameworks (PyTorch, TensorFlow). * Experience building fine-tuning pipelines end to end: training data curation, supervised fine-tuning, evaluation, and deployment. * Solid grasp of AI system design: ML model lifecycle (MLOps), agents, tool use, evaluation harnesses, guardrails, and observability. * Deep experience with Google Gemini Enterprise / Vertex AI; basic working knowledge of Microsoft AI Foundry and AWS Bedrock. * Experience leading and growing engineering teams, and supporting pre-sales: proposals, demos, and solution scoping with clients. * Excellent communication skills and comfort collaborating across teams and with stakeholders. * Strong business acumen with an interest in business-facing work. * Adaptability and a start-up mentality to thrive in a dynamic environment. Preferred: * Google Gemini Enterprise ecosystem (Vertex AI, Agent Builder) as the primary stack; basic knowledge of Microsoft AI Foundry and AWS Bedrock Why Join Us We are united by our values and strengthened by our hybrid expertise. * There is always a way: We're from the breed of does, of diggers, of makers. Because ideas are valuable only if executed. * Client trust is won on the field: Addressing client needs flows better hands on at their side. * If not used, it is useless: Our love for technology translates into a steep desire for adoption, true brilliance is about impact. * If not shared, our work is not done: Sharing knowledge is the best way to button up a mission, benefitting clients and colleagues. * We learn everyday: Tech is a land where everything moves at the speed of light, you better be ready to challenge yourself. The estimated base compensation for this role starts at $200,000 (NYC location). Individual compensation is determined by skills, qualifications, and experience. In addition, this role is eligible for competitive benefits.
