AI Engineer Must be Mandarin and English Fluent

AI Engineer

Position Overview

We are seeking an AI Engineer to join our Global Analytics team in London. This role is focused on the end-to-end lifecycle of production-grade AI from training and fine-tuning specialized models to architecting high-performance inference pipelines.

The ideal candidate views AI as a rigorous engineering discipline. Beyond building models you will be responsible for writing high-quality maintainable Python code and ensuring that every solutionwhether a voice agent or a document processoris built for reliability low latency and global scale.

Key Responsibilities

• Model Training & Fine-Tuning: Lead the adaptation of Large Language Models (LLMs) for domain-specific tasks using techniques likeLoRA QLoRA and PEFT to balance performance with resource efficiency.
• Inference Optimization: Architect and optimize inference pipelines to minimize TTFT (Time to First Token) and maximize throughput. This includes implementing quantization caching strategies and efficient batching.
• Production Engineering: Build and maintain real-time AI pipelines usingWebSockets and SSE ensuring seamless low-latency delivery for voice (ASR/TTS) and text applications.
• Architecture & MLOps: Deploy and orchestrate models within containerized microservice architectures (Docker/Kubernetes) ensuring robust monitoring security and scalability.
• Collaborative Delivery: Work closely with Business Analysts and internal stakeholders to bridge the gap between commercial requirements and technical implementation.

Technical Requirements

• Professional Experience: 5 years in AI/ML engineering with a documented history of moving complex models from research into production.
• Python Mastery: Deep proficiency inPython. You have a strong commitment to clean coding standards (SOLID/DRY) modular design and comprehensive unit/integration testing.
• Generative AI Deep Dive: Hands-on experience with LLM training cycles parameter-efficient fine-tuning (PEFT) and sophisticated prompt engineering.
• Inference Stack: Experience with high-performance inference servers (e.g.vLLM TGI or Triton) and an understanding of how to optimize models for GPU deployment.
• Infrastructure: Comfortable working in Linux-based environments and proficient in managing containerized workloads and automated CI/CD pipelines.
• Advanced RAG: Experience building production-ready Retrieval-Augmented Generation systems including vector database management and semantic search optimization.

Preferred Qualifications

• Experience in the insurance or financial services sector.
• Deep knowledge ofGPU architecture CUDA and hardware-level performance optimization.
• Familiarity with Document Intelligence frameworks (OCR layout analysis and multimodal extraction).
• MUST be fluent in Mandarin
