About This Opportunity

The Financial Conduct Authority (FCA) has highlighted the progressive potential of AI in strengthening the UK's investment culture, particularly in closing the advice gap and making financial mentorship more accessible. With only 31% of UK adults currently investing and the majority doing so without regulated advice, there's a clear opportunity to support better financial outcomes.

As one of the UK's largest providers of pensions and investments, Scottish Widows is well-positioned to lead this change. Within Lloyds Banking Group, the D2C Investments Platform supports Halifax Share Dealing Ltd. and Ready-Made propositions via Embark and FNZ, delivering investment solutions across trusted brands like Lloyds, Halifax, and Bank of Scotland. Our mission involves redefining the investment experience for our 26 million customers across the UK, harnessing the power of AI.

• Troubleshoot and resolve issues related to AI systems: ensure smooth operation and rapid recovery from technical challenges.
• Keep up to date with the latest AI technologies and standards: continuously improve systems through innovation and best practice.

What you'll need

• Prompt engineering expertise: Designed and refined prompts to optimise multi-agent AI systems, applying techniques like zero-shot prompting and RAG with precision and situational awareness.
• Expert-level Python development: You've built high-performance applications, developed custom modules, and integrated Python with other systems using advanced features and libraries.
• Applied machine learning: You've selected appropriate models for multifaceted scenarios, diagnosed performance issues, and improved outcomes through hands-on experience.
• Software engineering best practices: You use design patterns to build scalable, maintainable solutions and lead code reviews to ensure quality across the team.
• DevOps leadership: You've driven automation and continuous improvement across the development lifecycle, ensuring every build was fast, secure, and reliable.
