AI Engineer

As a Senior AI Engineer, you'll work with a global team of engineering and product teams to implement state-of-the-art AI-enabled digital solutions transforming P&C insurance globally. This position spans three core disciplines: applied AI/ML, production AI/LLM systems engineering, and agentic AI systems offering the opportunity to work across the full AI product lifecycle from model development to production deployment.

Major Responsibilities

• Work closely with AI engineers and product teams to design, build, and deploy ML/AI solutions solving complex business challenges in cloud environments (CPU & GPU).
• Research & implement state-of-the-art LLM techniques including post-training (e.g., SFT, GRPO, RLHF), prompt engineering, and evaluation frameworks.
• Build production AI services including middleware, prompt management layers, inference pipelines, LLM-Ops tooling, and async messaging systems (e.g., Kafka) for model integration into applications.
• Design and develop agentic AI systems end-to-end from orchestration frameworks (Lang Chain, CrewAI, Auto Gen) to memory/data layers, tool integrations, and multi-agent workflows.
• Implement observability, monitoring, and evaluation for production AI systems including prompt tracing, agent behavior analysis, and performance metrics.
• Build reusable pipelines, processes, and tools to streamline AI/ML workflows from development to production.
• Ensure high-quality, maintainable code that meets business objectives, quality standards, and development guidelines.
• Manage stakeholder expectations and communications while adapting to shifting priorities.

Must Have:

• 5+ years' experience in Machine Learning/AI Engineering/Software Engineering/Data Science with deep expertise in production Python development.
• Strong knowledge of ML frameworks and libraries (Transformers, trl, PyTorch, Lang Chain, Llama Index, or similar).
• Experience building distributed, high-throughput, low-latency systems.
• Experience with containerization and orchestration technologies (Kubernetes, Docker).

Strong Preference Given To:

• Experience with the full LLM lifecycle: dataset curation, post-training, evaluation, data labelling and management, and deployment.
• Production AI systems experience: building APIs, middleware, prompt management, inference optimization, or LLM-Ops infrastructure.
• Agentic AI development: building autonomous agents, multi-agent systems, memory/state management, tool use, or agent evaluation frameworks.
• Experience with observability/monitoring tools for AI systems (Lang Smith, Weights & Biases, custom tracing solutions).
• Understanding of system architecture design and technical feasibility tradeoffs.
• Full-stack development experience integrating AI into user-facing applications.
• P&C insurance domain knowledge.
