About the Job

Requirements

  • At least 5 years of AI/ML engineering experience, with strong fundamentals in data structures, algorithms, and system design, and production experience with Python.
  • Deep applied AI/ML knowledge covering natural language processing and transformers, generative models such as GANs and VAEs, reinforcement learning, classical machine learning, and statistical modelling.
  • Advanced large language model and retrieval-augmented generation engineering experience, including prompt pipelines, embeddings, vector stores such as FAISS, Milvus, or Pinecone, hybrid retrieval, grounding, hallucination mitigation, and evaluation frameworks.
  • Experience with LLMOps and MLOps, including automated testing, drift monitoring, safety and guardrails, machine learning continuous integration and delivery, telemetry, lineage, and governance.
  • At least 5 years of experience with cloud platforms, preferably Azure, or GCP or AWS, and modern data infrastructure.
  • Experience with containerization and continuous integration and delivery pipelines.
  • Proven ability to work with clients in a technical consulting, solutions engineering, or product engineering role.
  • Ability to navigate ambiguous requirements and rapidly iterate toward solutions.
  • Familiarity with enterprise security, compliance, and governance requirements, including SOC 2, GDPR, and HIPAA.
  • Demonstrated ability to lead multidisciplinary teams across engineering, data science, architecture, product, and design through complex delivery cycles.
  • Excellent communication skills to explain complex technical concepts to technical and non-technical audiences.
  • Background in machine learning, with hands-on experience training or fine-tuning models.
  • Significant management experience in consulting or industry.

Responsibilities

  • Partner with clients to understand workflows, constraints, success metrics, and incentives, and turn ambiguous business problems into concrete AI solutions.
  • Translate business challenges into well-scoped AI use cases, including prediction, automation, retrieval, and agent workflows.
  • Define minimum viable product scope, data requirements, and evaluation criteria jointly with stakeholders.
  • Build rapid prototypes using large language models, retrieval-augmented generation pipelines, fine-tuning, agents, and traditional machine learning models where appropriate.
  • Design and implement AI architectures covering data ingestion, feature pipelines, embeddings, vector stores, model selection, tuning, and evaluation, including prompt design, guardrails, and system instructions.
  • Integrate AI components with existing client systems, including application programming interfaces, data warehouses, and software-as-a-service platforms, and optimize latency, cost, reliability, and scalability.
  • Deploy solutions into client cloud, hybrid, or on-premises infrastructure while navigating security, compliance, data residency, and legacy-system constraints.
  • Set up monitoring for model performance and drift, prompt failures, hallucinations, and regressions.
  • Provide technical training and knowledge transfer to client teams.
  • Capture reusable patterns, architectures, and accelerators.
  • Contribute to internal playbooks and reference implementations.
  • Share lessons learned across engagements.
  • Support pre-sales through technical expertise and demonstrations.
  • Stay current on AI tools and model capabilities.
  • Work closely with EY partners, engagement teams, and senior client stakeholders to design, build, and deploy AI systems for complex, regulated, and large-scale environments.
  • Carry solutions from concept through production and enable clients to operate and evolve their AI capabilities sustainably.
  • Travel regularly and work at client sites when required.

Desired Qualifications

  • Experience building and deploying AI agents or autonomous systems in production.
  • Experience using modern Python AI tools such as LangChain, LangGraph, LlamaIndex, and FastAPI.
  • Previous experience in a forward-deployed, field engineering, or technical account management role.
  • Domain expertise in finance, healthcare, government, or manufacturing.
