We are looking for a Software/Data Engineer to join a growing team focused on transforming core technology systems and data pipelines within a leading investment management environment. This is a hands-on role involving the modernisation of market data processes, resolution of production issues at the root cause, and delivery of reliable, scalable solutions.

You will be joining a collaborative team tasked with replacing legacy infrastructure and delivering long-term improvements across data platforms and critical operational systems.

Key Responsibilities

• Rebuild and optimise Python-based data pipelines, improving performance, reliability and scalability.
• Investigate and address root causes of recurring production issues.
• Enhance data throughput and system robustness across operations, market data and portfolio systems.
• Contribute to the delivery of clean, testable, and well-documented solutions within a containerised environment.
• Collaborate with software engineers, production support, and business users to ensure effective delivery.
• Support the development of high-quality APIs (REST and GraphQL) and integration with internal and third-party systems.

Required Experience

• Strong Python programming skills, ideally within data engineering or integration-heavy environments.
• Solid experience building and orchestrating ETL pipelines.
• Good understanding of data transformation tools and working with structured/semi-structured data.
• Proven ability to implement meaningful tests around business logic.
• Proficiency with SQL and working with databases and data lakes.
• Experience working in CI/CD environments (e.g. GitHub Actions, Sonar) and with containerised systems (e.g. Docker).
• Ability to operate both independently and as part of a collaborative team.
• Strong communication skills and ability to engage with business stakeholders directly.

Desirable Experience

• Familiarity with legacy systems (e.g. C#) and willingness to interact with them where necessary.
• Exposure to Cloudera Data Platform or similar big data environments.
• Experience with tools such as Apache Hive, NiFi, Airflow, Azure Blob Storage, and RabbitMQ.
• Background in investment management or broader financial services, or a strong willingness to learn the domain.

The Role Offers

• The opportunity to be part of a new, focused engineering team, supported by an experienced wider technology group.
• A hybrid working model based in the City of London (typically 2-3 days per week in the office).
• Exposure to business-critical systems and direct involvement in the improvement of data services used across the firm.
