Job description

Job Description:

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.

Key Responsibilities

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

Platform Development & Engineering

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

Trading Workflow & System Design

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

Agile Development & Delivery

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

Platform Capability Build

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)

Qualifications & Experience

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

Education & Personal Attributes

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
