Build evaluation, testing and guardrails to prove feasibility, quality and safety before scale.
Partner daily with the AI Product Owner to translate requirements into working solutions and iterate on feedback; surface constraints, effort and risk early to inform scale or stop decisions.
Prepare clean, documented handovers to D&T and PIC, including architecture notes, evaluation evidence and known limitations.
Apply model-cost / cost-per-outcome awareness in design and model choices.
Contribute reusable patterns, components and sample agents to the China AI platform and builder community.
3. Required Capabilities & Competencies
Hands-on AI / software engineering: rapid prototyping, applied development and integration of AI and agentic solutions; production-quality Python.
Agentic and RAG engineering: embeddings, re-rankers, vector databases, model and API integration, orchestration, prompt and context engineering, evaluation and guardrails.
Working knowledge of small language model fine-tuning and evaluation, MLOps and LLMOps, CI/CD and secure, privacy-aware deployment.
Model-cost / cost-per-outcome awareness and pragmatic engineering trade-offs.
Builder mindset: ships working solutions fast with rigor, curiosity and pragmatic engineering judgment, with strong cross-functional collaboration.
Bachelor’s degree or above in Computer Science, Software Engineering, Artificial Intelligence, Data Science or a related discipline.
8+ years of relevant technology experience, including 5+ years of hands-on software, data or AI engineering experience and demonstrated delivery of AI/ML or agentic solutions.
Ability to work across business, product, technology, data and governance stakeholders in a matrixed environment.
4. Key Collaboration
The role works in the AITO AI engineering pool under the AIT Acceleration Lead, partnering daily with the AI Product Owner in a PO-led POD. It builds on the China AI platform and LLM foundation provided by AI Platform & Foundation, delivers the AICL AI layer with D&T Data Engineering & Semantics and GCA DSM, and prepares the acceleration-to-scale handover with D&T Enterprise Engineering, Deployment & Operations and the Pfizer Innovation Center (PIC). It also engages relevant China Business Units and, where useful, International AIT engineering communities.
5. Measures of Success
High-value ideas turned into working, evaluated prototypes and MVPs at speed.
Technical feasibility, quality and safety proven through evaluation and guardrails before scale.
Clean, well-documented handovers that accelerate production engineering by D&T and PIC.
Reusable patterns, components and AICL AI-layer assets adopted across use cases.
