Your opportunity
We are looking for someone who is already deep into AI, not just familiar with it, to join our EMEA Equity Trading team. You will analyse trading data, automate desk outputs and build tools that seek to improve our processes. This is a technical role, not a trading role: you will learn the domain from one of the most experienced equity trading teams in the industry, but you need to arrive with genuine AI and data capability from day one. If you are the kind of person who builds things before being asked, picks up new tools fast and is not satisfied with how things were done yesterday, this is worth reading on.
Responsibilities
- Own the AI and automation agenda for the team. Identify where AI tooling can replace manual processes, design the solution and build it. This is not a role where you execute someone else\'s backlog; you are expected to bring ideas, test them quickly and ship what works.
- Work directly with Traders and Portfolio Managers to understand data consumption, pain points, and workflow changes. Deliverables must be clear, well designed, and grounded in how the desk operates.
- Analyse trading datasets using Python and AI tooling to surface trends, inefficiencies and opportunities. You will encounter execution analytics, Transaction Cost Analysis, Algo Wheel configuration, market microstructure and European regulatory requirements. Comfortable with complex, domain-specific data and rapid learning is required.
- Modernise the desk\'s outputs from a consumable content standpoint so they are automated, visually sharp and readable.
- Help the wider team build confidence with AI tooling. Run demos, share practical examples, explain what works and why. Bring the desk along so the team\'s capability rises, as well as your own.
- Contribute to the firm\'s wider community of AI practitioners, sharing what works and evolving best practices for AI adoption across the organisation.
Must have skills
- A degree in a technical or quantitative discipline, or equivalent professional experience. No specific degree subject is required; capability and aptitude matter more than the title on the certificate.
- Python and AI-assisted development. You will write code with AI, not without it. Comfortable working with agents and AI coding tools (GitHub Copilot, Claude Code or similar) to build, debug and iterate. Engineering judgement to ensure what you produce is safe, reliable and fit for production use.
- AI proficiency. Prompt engineering, LLM-assisted analysis, agentic workflows, tool orchestration. You should be the person your peers come to when they want to know what is possible.
- Numerically sharp. Comfortable working with large, complex datasets and spotting when outputs do not make sense. Strong communication skills and fluency with numbers in a trading context.
- Delivery mindset. Builds things that work and last, whether handed to a technology team to productionise or owned and maintained on the desk.
- Stakeholder communication. Ability to explain technical trade-offs clearly to non-technical audiences.
- 2-3+ years in a technical, data or analytics environment. Financial services exposure is a plus, not a prerequisite.
Nice to have skills
- Demonstrated personal interest in AI beyond the workplace. Curiosity and initiative toward AI projects are valued and may be explored during the interview process.
- Financial knowledge. Exposure to equity markets, trading, execution analytics, algorithmic trading or market microstructure. Interest in developing this knowledge (e.g. CFA study) is valued.
- SQL and data platforms. Experience in querying structured data, ideally with Snowflake or similar cloud data warehouses.
- Data visualisation and design. Experience with dashboarding tools (e.g. Streamlit, Power BI or similar).
- Platform-level automation. Experience with low-code/no-code platforms, LLM observability tools, or managed model APIs.
- Modern development practices. Familiarity with Docker, Terraform, CI/CD pipelines, Git.
- Agent orchestration frameworks. Experience with LangChain, Semantic Kernel, AutoGen or similar is a plus.
