About AstraZenecaAt AstraZeneca, we put patients first and strive to meet their unmet needs worldwide. Working here means being entrepreneurial, thinking big and working together to make the impossible a reality. If you are swift to action, confident to lead, willing to collaborate, and curious about what science can do, then you’re our kind of person.Beijing Site infoThe Beijing AI Center is a new strategic investment by AstraZeneca to accelerate drug discovery through AI. The center brings together AI researchers, computational scientists, and platform engineers to apply foundation models, agentic AI, and large-scale scientific computing to real R&D problems. Situated in one of the world's most dynamic AI talent markets, the center operates at the intersection of AI and biologics discovery, computational chemistry, and data-driven drug development.The center is structured around three pillars: Discovery verticals (biologics engineering, computational chemistry) that own the science, Data & AI Platforms (this role) that own the capabilities, and R&D IT that owns the infrastructure. A dedicated on-premises GPU cluster provides the compute backbone, operated by IT and shaped by platform standards.About the Beijing AI CentreThe Beijing AI Center is a new strategic investment by AstraZeneca to accelerate drug discovery through AI.

A dedicated on-premises GPU cluster provides the compute backbone for training and inference workloads, supported by both cloud and local infrastructure.About the RoleAstraZeneca's Beijing AI Center brings together Discovery science, AI platforms, and infrastructure to accelerate drug discovery through artificial intelligence. The Senior AI Engineer is the first AISI platform hire in Beijing, responsible for making the center's GPU investment productive for science teams.You will design and deliver the distributed training infrastructure, AI engineering standards, and compute orchestration policies that enable Discovery AI scientists to train foundation models, run fine-tuning experiments, and scale inference workloads. You are the bridge between IT's hardware infrastructure and Discovery's scientific workloads.This role sits in AISI's AI Centre of Excellence, a horizontal capability team that serves all Discovery verticals (Biologics Engineering, Computational Chemistry, Safety) in Beijing. You set the AI engineering standards. Discovery teams bring the science. IT provisions the infrastructure. You make it all work together.What You’ll DoDistributed Training (First 90 Days)

Design and validate multi-node multi-GPU training templates (DDP, FSDP) for NVIDIA H20 GPUs
Build operational runbooks covering common failure modes, checkpointing, recovery
Establish baseline performance benchmarks (throughput, step time, scaling efficiency)
Optimize data loading pipelines to eliminate I/O bottlenecks in distributed settings

AI Engineering Standards

Define training method standards: naming conventions, experiment configuration, model registry requirements, reproducibility criteria
Create scheduling policies: GPU quota rules, priority tiers, job templates for the center's Kubernetes/Run:AI platform
Establish compute triage process: how science teams request and receive GPU allocation
MLOps: experiment tracking, model registry, CI/CD for ML, Kubernetes
Streamlining non-AI pipeline and workflow dependencies

Fine-tuning and Optimization

Build reusable fine-tuning pipeline templates for protein language models and scientific AI workloads
Optimize training code for H20 GPU to boost efficiency and throughput
Collaborate with NVIDIA on hardware-specific optimizations

Cross-Organizational Coordination

Translate Discovery team workload needs into infrastructure requirements for IT
Operate as "business owner" for AI compute, while IT operates as "system owner"
Participate in weekly coordination meetings across Discovery, AISI, and IT

What You BringRequired

5+ years of experience in distributed deep learning training (DDP, FSDP, DeepSpeed, or equivalent)
Strong PyTorch expertise with production-grade model training
Experience with GPU workload optimization and multi-node cluster management
Kubernetes job scheduling experience (Kubeflow, Slurm, Run:AI, or equivalent)
Experience setting AI/ML engineering standards for teams (not just personal projects)
Hands-on experience improving Tranformer-based models (ex: FlashAttention or related optimizations)
Ability to work full-time in Beijing

Preferred

Parameter-efficient fine-tuning methods (QLoRA, LoRA, adapters)
Reinforcement learning training infrastructure
AWS China or Alibaba Cloud experience
NVIDIA H20 or H100-series GPU familiarity

Desirable

Biopharma domain knowledge (molecular simulation, protein folding, drug discovery)
Experience working across organizational boundaries (e.g., AI platform team serving multiple science groups)
