• Excellent collaboration and communication skills, with the ability to lead solution architecture design, technical diagramming, and whiteboarding sessions for both engineering and executive audiences, and to represent the organisation credibly in external technical engagements

Education

• Bachelor's degree or higher in Computer Science, Software Engineering, Artificial Intelligence, or a related technical field, or equivalent practical experience

Responsibilities

Design, code, and lead delivery of scalable AI platforms and intelligent applications that bring emerging AI capabilities into production across partner ecosystems

• Act as a hands-on technical leader, spending significant time designing, coding, reviewing, debugging, and improving production systems that support AI-powered products and partner integrations
• Own the end-to-end technical architecture for the AI partner ecosystem, producing system diagrams, architecture documentation, and design standards that align engineering efforts with product vision and stakeholder expectations across multiple initiatives
• Architect and evolve the agentic workflows, skills, and tool-use integrations that allow AI systems to interact with Moody's platforms and third-party services via MCP and related protocols, and define the patterns other engineers build against
• Implement advanced large language model applications using retrieval-augmented generation, prompt orchestration, evaluation frameworks, model optimisation, agentic workflows, and tool integration
• Build and deliver compelling proofs of concept, live demonstrations, and prototype solutions that showcase platform capabilities and accelerate partner adoption, then harden them into scalable, maintainable production systems
• Serve as the senior technical advisor in client- and partner-facing engagements, effectively communicating complex AI architectures, solution options, and recommendations to both technical and non-technical audiences
• Deploy, monitor, and optimise integrations across cloud environments including Microsoft, AWS, GCP, and Databricks, establishing operational and reliability standards for the team
• Define and champion integration patterns and protocols, including Model Context Protocol (MCP) and A2A, ensuring seamless interoperability across platforms and influencing how these standards are adopted across the organisation
• Track and assess AI partner technical roadmaps from hyperscalers and leading AI providers, identifying opportunities to enhance products and translating partner capabilities into actionable engineering work
• Establish engineering best practices through hands-on contribution, code reviews, technical design reviews, automated testing, observability, and operational excellence
• Champion responsible AI practices including evaluation frameworks, model lifecycle management, prompt versioning, monitoring, and continuous improvement of AI-enabled products
• Partner with product managers, engineering leaders, and business stakeholders to translate strategic priorities into robust, buildable technical solutions, and contribute to build/buy/partner decisions
• Mentor engineers through practical technical coaching, pairing, code reviews, design feedback, documentation, and example-setting as a senior individual contributor
