The position

We are looking for a Senior ML & LLM Platform Engineer to join the Enterprise Data Science Group an outstanding MLOps and LLMOps engineer who loves GenAI and running AI in production at scale and thrives on:

• Serving open-weight LLMs at scale: GPU capacity and autoscaling throughput batching quantization caching cost per token use of tools and more.

• Setting the MLOps and LLMOps standards for the group: experiment tracking model and prompt registries infrastructure-as-code release practices etc.

• Evaluation and observability for non-deterministic systems: monitoring regression suites and cost tracking for LLM pipelines.

• Shaping our development and pre-production environments into a best-in-class platform for testing and experimentation where large-scale experiments are fast reproducible tracked and safe to run against real data.

• Improving the CI/CD engineering and cloud foundations behind our ML/LLM pipelines: performance cost and reliability with data at scale.

• Designing agentic AI services and applications including multi-agent systems and visual interfaces taking them from prototype to production while working with data scientists on ML and GenAI technologies (agents RAGs fine-tuning hosting open weight models MCPs) that raise the bar of accuracy and impact.

We are looking for

• 5 years in MLOps / ML / AI / data / software engineering with production systems you deployed and operated and a proven track record of working alongside data scientists and researchers.

• Hands-on experience with GenAI technologies (LLMs vector DBs and RAG MCP agent platforms open-weight models) and with serving them at scale: orchestration architecture caching monitoring and ownership of latency throughput and cost.

• Fluency in the ML/LLM Ops toolchain: experiment tracking model and prompt registries production monitoring (MLflow or equivalents) etc.

• Deep understanding of LLM architectures: MoE (Mixture-of-Experts) attention variants tokenization quantization KV caching and batching.

• Familiarity (practical experience advantage) with distributed training and inference parallelism strategies - FSDP (Fully Sharded Data Parallel) data tensor and pipeline parallelism.

• A generalist mindset: comfortable venturing beyond ops into data engineering agent development and data science when the problem calls for it.

• A BSc (MSc an advantage) in computer science mathematics or another quantitative field or equivalent experience.

Ways to stand out

• An entrepreneurial mindset: following emerging technologies closely spotting what would keep us at the state of the art and building support across the organization to make it happen.

• Strong data engineering foundations across cloud and DevOps: AWS/Azure/GCP Databricks/Snowflake Spark infrastructure-as-code CI/CD and scheduled data pipelines.

• A track record in data science or applied research or in building agentic systems.
