Job description

As a part of the Central AI-Core Studio & Delivery team, this role would require you to drive the design, build, and production delivery of AI-enabled applications for our core business lines.

Key Responsibilities

• Design and build end-to-end AI-powered applications, including retrieval pipelines, LLM orchestration layers, backend APIs, and user-facing interfaces.
• Own the full software development lifecycle from requirements and architecture through testing, deployment, and post-launch iteration.
• Integrate LLM APIs, vector databases, and retrieval-augmented generation into production applications, applying agentic orchestration where needed.
• Evaluate AI models and retrieval approaches, defining evaluation criteria and iterating on production performance data.
• Own CI/CD pipelines, containerisation, observability, and secure cloud deployment, and document architectural decisions and trade-offs.
• Contribute reusable components and shared engineering standards to the AI platform.
• Work directly with business teams and AI PMs in a forward-deployed model, communicating progress and risks to technical and non-technical stakeholders.

About You

• A track record of shipping production software that people rely on - applications you’ve built, debugged, and improved under real operating conditions.
• Strong Python proficiency, with experience in REST APIs, cloud deployment, and containerisation.
• Hands-on experience with LLM APIs (OpenAI, Anthropic, or equivalent) and retrieval/vector database systems.
• Solid understanding of software architecture, testing practices, and production operations.
• It will be advantageous if you have experience in agentic orchestration frameworks (LangChain, LangGraph, AutoGen) and frontend development with React and TypeScript.
• It will be advantageous if you are familiar with the Architecture, Engineering and Construction industry, infrastructure, or enterprise workflow domains, and AWS, Azure, or GCP environments.
