We are currently seeking a AI Foundational Model Engineer to join our team in Jersey City, New Jersey (US-NJ), United States (US). Role purpose Design, build, deploy, and optimize enterprise-grade AI systems powered by foundation models, LLMs, retrieval-augmented generation, and agentic AI workflows. The role converts AI concepts into secure, scalable, observable, and supportable production systems suitable for a regulated financial-services environment. Primary ownership • Production LLM applications, RAG pipelines, AI services, and model-serving integrations. • End-to-end LLMOps/MLOps lifecycle from experimentation to deployment, monitoring, evaluation, rollback, and continuous improvement. • Model adaptation, inference optimization, APIs, observability, and operational readiness for GenAI solutions. Key responsibilities • Design and implement LLM-powered applications such as knowledge assistants, document intelligence solutions, workflow agents, summarization tools, and decision-support systems. • Build RAG pipelines using embeddings, chunking strategies, vector databases, semantic retrieval, reranking, response grounding, and citation patterns. • Adapt and optimize models using LoRA, PEFT, instruction tuning, distillation, transfer learning, quantization, and domain adaptation techniques. • Develop scalable APIs, microservices, model-serving components, and integration patterns across cloud, hybrid, or containerized environments. • Optimize inference workloads for latency, throughput, token efficiency, cost, reliability, and user experience. • Implement model and application observability, including prompt logs, retrieval quality, hallucination indicators, drift signals, feedback loops, cost telemetry, and service health. • Embed security, privacy, Responsible AI, and model risk controls into AI application design and delivery. • Create production documentation, runbooks, release notes, test evidence, and audit-ready implementation records. Must-have candidate profile • 7+ years in AI/ML engineering, platform engineering, software engineering, or applied machine learning. • Hands-on experience with LLMs, transformers, embeddings, RAG, semantic search, and GenAI application patterns. • Strong Python engineering skills with PyTorch, TensorFlow, Hugging Face, LangChain, LlamaIndex, Semantic Kernel, or equivalent frameworks. • Experience deploying production AI services using APIs, containers, Kubernetes, CI/CD, cloud-native services, and monitoring platforms. • Practical knowledge of model evaluation, fine-tuning, inference optimization, and secure data handling. Preferred experience • Banking, risk, compliance, financial crime, operations, or enterprise technology background. • Experience with Azure OpenAI, AWS Bedrock, Vertex AI, Databricks, vLLM, Triton, MLflow, Kubeflow, or model gateways. • Exposure to model risk, AI governance, audit controls, AI cost governance, and private or open-source LLM deployments.
