Python Developer

Role Overview

As part of its ambition to become a Top 3 contributor in the European ETF market, our client is investing significantly in the evolution of its ETF Market Making platform, with a strong focus on advancing Automated Market Making (AMM) and client RFQ pricing capabilities.

This role is centred on the design, development, and delivery of a next-generation electronic trading platform, supporting global trading activities across Europe, the US, and Emerging Markets. The objective is to build a scalable, high-performance platform, while developing long-term expertise to enable future trading and technology initiatives.

You will act as a hands-on developer within the Front Office trading environment, driving the build and enhancement of critical ETF trading components:

• Design and develop core components of the ETF electronic trading platform, with a focus on performance, scalability, and low latency
• Contribute to the end-to-end build and deployment of features across EU, US, and Global/Emerging Markets
• Implement enhancements to AMM and RFQ pricing workflows, improving automation and client responsiveness
• Participate in the architecture and design of distributed systems, ensuring robustness and extensibility

• Analyse existing ETF trading workflows (Blotter, booking, validation chain) and translate them into improved system designs.
• Lead the design and development of the new ETF Blotter within the Edge Board platform
• Build clean, efficient, and maintainable data flows between trading systems (ETF Portal, pricing engines, booking systems)
• Contribute to the modernisation of trading interfaces and tools used by the desk

• Work closely with traders and quants to capture requirements and rapidly deliver solutions
• Contribute to short development cycles, enabling fast iteration and continuous delivery of trading features
• Ensure high-quality code standards, testing, and deployment practices
• Drive automation and optimisation across the development lifecycle

• Develop reusable frameworks, libraries, and tools to support the ETF trading ecosystem
• Contribute to the scalability and industrialisation of the platform for future asset classes or regions
• Enhance monitoring, observability, and performance tooling from a development perspective (not pure support)

Mandatory Skills

• Strong experience in Front Office trading system development, ideally within electronic trading or market making environments
• Solid software engineering background with:
• Python (advanced)
• SQL / data handling
• Strong understanding of client-server and distributed architectures
• Experience working in Linux/Windows environments
• Proven ability to design and build production-grade systems, not just maintain them

Desirable

• Exposure to C++ (performance-critical components)
• Knowledge of ETF products, RFQ workflows, or pricing systems

• Degree from a top university in Computer Science, Engineering, or related field
• Strong analytical and problem-solving skills, with the ability to operate in complex, fast-paced trading environments
• Self-starter with a strong engineering mindset and ownership culture
