We are seeking an AI Engineer to join our IT-AI team, contributing to the development and enhancement of AI-powered product features—primarily within our Continuous Product Enhancement (CPE) initiatives. You will work hands-on with AI systems, focusing on building, testing, and improving AI capabilities that deliver value to end users.

This role operates within a collaborative team structure, working alongside experienced colleagues and contributing to shared delivery goals. You will focus on the application layer—building and refining AI features—while working within the platform infrastructure.

You Will:

AI Feature Development & Enhancement

• Build and improve AI-powered features within existing products (CPE focus)
• Develop and maintain agent tools and integrations
• Refine and optimise prompts for production use cases
• Support experiment tracking and model versioning (e.g., MLflow)

Testing & Quality

• Build and maintain test functions for existing AI tools—including exploring agent-based testing approaches where AI validates AI
• Develop and execute testing frameworks for AI/agent evaluation
• Build and maintain quality gates and automated checks
• Support champion/challenger validation before promotion
• Contribute to model observability and dashboard development—tracking performance, quality, and usage patterns

Collaboration & Delivery

• Work closely with Data Scientists and AI engineers on productionising research outputs
• Coordinate with Platform Engineers on deployment and infrastructure needs
• Support tactical AI solutions in collaboration with team members and other groups—responding to emerging business needs
• Participate in code reviews, documentation, and knowledge sharing
• Operate within team processes and contribute to shared delivery goals

You Have:

Required Skills and Qualifications

• Masters or PHD, or an equivalent amount of professional working experience
• 3+ years of experience in ML and AI engineering
• Proficency in Python programming skills
• Understanding of ML/AI lifecycle and experiment tracking
• Good communication skills for working with technical and business teams

Good to Have

• Experience with MLOps tooling (e.g., MLflow)
• Exposure to AI and agent frameworks (e.g., AWS Strands, Azure AI Agent Service, LangChain, LangSmith, CrewAI) is a plus
• Experience with GenAI application development
• Experience with cloud platforms (AWS, Azure) or data platforms (e.g., Databricks)
• Financial services background
• Familiar with Git and CI/CD workflows

What We're Looking For

• Strong problem-solving skills and attention to detail
• Clear communication—able to work effectively across teams
• Works well as part of a team with shared ownership
• Reliable, delivers quality work, and follows through on commitments
• At ease with change—you'll help define how we work, not just follow a playbook
• Eager to learn and grow within a supportive team environment

What This Role Is Not

This role focuses on AI feature development, not infrastructure. Platform engineering responsibilities (IaC, CI/CD pipelines, infrastructure, MCP server deployment) sit with the Platform Engineering team.
