Job: Junior Data Engineer (d/w/m)

OpenSanctions helps to keep people and companies accountable for their political and economic actions. We build a database that tracks a wide range of entities in the public interest: sanctioned companies, politicians, fraudsters and criminals. Originally built to support anti-corruption journalists, OpenSanctions has also become a powerful tool used for customer screening, anti-money laundering compliance and in-depth investigative research.

We take pride in providing a high quality dataset to the public and to our subscribers. Based on an open source data pipeline and providing a public search tool for everybody, we bring transparency and a commitment to accessibility and openness to the industry.

The role

You will help us to expand our coverage of people in political office and other positions of influence, sanctioned entities, and entities linked to other sources of risk. To do so, you will develop crawler programs that retrieve and structure data from international government websites. You will also be asked to fix and improve existing crawlers whenever they break, and when we decide refine our data model.

This role is ideal for early-career candidates who want to develop their programming skills from basic to intermediate. Writing crawler code (especially with the assistance of automated co-pilots) is a great way to understand coding best practices, web technology and data modeling. We expect candidates to have a keen interest in political systems, international affairs or the investigation of financial crime.

An ideal candidate has some basic understanding of some of these technical workflows:

• Experience of web scraping using Python
• Data cleaning using Python
• Running programs in a command line environment
• Web technologies such as HTTP and HTML
• Git, GitHub, pull request workflow
• Working with LLM-based coding tools (eg. Copilot, Cursor, Claude Code)

We expect all candidates to meet these criteria:

• An active interest in the meaning/relevance of the data in question.
• A keen eye for detail and data correctness.
• A passion for documenting datasets so that users will see its significance, and understand the relevant limitations of the source.
• Readiness to work in a small team and collaborate tightly.
• Resides within three timezones of CET, can travel to the Schengen zone for team meetings. (Applications from the American continent and East Asia will be rejected)

How this works

We build crawlers using tooling in our own framework, zavod, which is carefully designed for the nature of our data pipeline and our scaling needs. Each crawler can focus on what is unique about the data source it is designed to integrate into our database.

We maintain a backlog of tasks for data crawling. These tasks comprise either writing a new crawler for a data source we don’t track yet, or updating an existing crawler if it is broken or incorrect. There's a list of issues with existing crawlers that require fixing.

The deal

• Flexible working hours and unbureaucratic work environment
• We’re building a small and sustainable business, not a grind-you-to-the-bones startup.
• We’re developing an impactful product that is getting adopted rapidly.
• Home office, remote work, or co-working location in Berlin – your choice.
• Option for employment under German law for residents of Germany.
