About the Tax Justice Network

The Tax Justice Network is an independent international network, launched in 2003. It is dedicated to high-level research, analysis and advocacy in the area of international tax and financial regulation, including the role of tax havens. We map, analyse and explain the harmful impacts of tax evasion, tax avoidance and tax competition, and support the engagement of citizens, civil society organisations and policymakers with the aim of a more just tax system. We pursue systemic changes that address the international inequality in the distribution of taxing rights between countries; the national inequalities – including gender inequalities – that arise from poor tax policies; and the national and international obstacles to progressive national tax policies and effective financial regulation. The Tax Justice Network is supported by grants from Norad, the European Union, the Ford Foundation and others. We are a virtual organisation, with staff working from home across multiple countries and continents.

Role description

The data engineer will contribute to developing and maintaining a range of data driven outputs and systems, including the Financial Secrecy Index,  Corporate Tax Haven Index, Illicit Financial Flows Vulnerability Tracker and the State of Tax Justice report.

The role will involve designing, developing and maintaining the Tax Justice Network’s data systems. It will include (i) developing and maintaining several streams of datasets (panel and cross-sectional) that include legal, financial and other economic data; (ii) creating visualizations of data; (iii) engaging with existing systems at the Tax Justice Network (such as databases, websites, and analytical tools) and proposing and implementing their improvements and additions. In addition, the data engineer will work with our data scientists and researchers to review and advise on the design and procurement of data systems in public administrations and may, depending on skills, support the Tax Justice Network’s websites, including basic web design and visualizations.

We expect the data engineer to obtain a good understanding of our work and subsequently to support colleagues both in internal data related tasks and in externally facing projects (e.g. advising government authorities). The data engineer is expected to be able to work independently to the highest data science standards, including documenting code, demonstrating exceptional attention to detail while prioritising and completing tasks to strict deadlines. The post-holder will be joining the Tax Justice Network’s data science team and collaborate with external IT consultants and suppliers.
