This firm is seeking a Senior ML & GenAI Engineer to architect and ship production-grade LLM agents and RAG pipelines, steer the full ML lifecycle from data prep to GPU-scaled deployment, and weave together modern tools and technologies into a secure, cost-aware platform. If you thrive on turning ambiguous ideas into high-impact GenAI products, and mentoring others to do the same, this is your playground.

Responsibilities:

Design, prototype, and build GenAI solutions, RAG document pipelines, and task-specific agents to support multiple business functions using tools such as LangChain/LlamaIndex, micro-services, Ray/KubeRay.

Design and orchestrate multi-step agent pipelines in n8n (or similar low-code orchestrators), integrating LLM prompts, external APIs, and human-in-the-loop escalations.

Own requirements data prep feature engineering classical ML or LLM fine-tuning (LoRA, PEFT, RLHF) offline/online evaluation MLflow registry, with automated drift and quality alerts.

Ingest from BigQuery, Redshift, object-store lakes (Parquet, Avro); generate embeddings and persist to vector DBs (Qdrant/PgVector); enforce governance via OpenMetadata and column-level ACLs.

Package with Docker, helm-deploy on Kubernetes; implement GPU scheduling, autoscaling, blue-green rollouts, and cost telemetry via Prometheus/Grafana; automate CI/CD in GitHub Actions.

Instrument tracing, metrics, and structured logs; run A/B or shadow tests; embed security, privacy, and cost-guardrails in every pipeline.

Translate ambiguous business ideas into executable roadmaps, run build-vs-buy analyses, set code standards, and coach peers on agentic patterns and ethical AI. Qualifications:

Bachelor's or Master's in Computer Science, Data Science, or equivalent experience.

8+ years designing and shipping ML/AI applications, including 3+ years with LLMs or Generative AI.

Demonstrated delivery of RAG or agentic systems in production (e.g. LangChain, LlamaIndex, n8n, or custom).

Expert-level Python and SQL; strong Spark, distributed data-processing, and performance-tuning skills.

Hands-on fine-tuning of foundation models; comfort with MLflow, Ray/KubeRay, and vector databases.

Deep familiarity with cloud warehouses (BigQuery, Redshift), lake formats (Parquet, Avro), and streaming/ingestion tools (e.g. Airbyte, Kafka/Pub-Sub).

Production experience with Docker, Kubernetes, Helm, and Git-based CI/CD pipelines.

Clear communicator able to gather requirements, set technical direction, and influence cross-functional teams.
