Your role & the team:

As an OSINT Researcher at SEON, you will be at the forefront of discovering, analyzing, and integrating publicly accessible data sources that enhance our fraud prevention capabilities. You will conduct in-depth investigations on websites, platforms, and mobile applications to extract actionable intelligence, develop research prototypes in Python, and collaborate closely with engineers to turn your findings into scalable, production-grade solutions. This role will work within our Data Enrichment Team.

This is a Remote position and the ideal candidate will be based in the EU.

What you'll do:

Core OSINT Research

• Conduct open-source investigations across websites, platforms, and mobile applications to uncover relevant and verifiable data points.
• Research hundreds of online sources and surface-level or deep web endpoints to identify patterns, behaviors, and structures for data extraction.
• Stay current with OSINT tools, cyber intelligence practices, and threat actor tactics in the digital fraud landscape.
• Collect, analyze, and organize intelligence from diverse public sources, including data breaches, forums, and leaked datasets.

Reverse Engineering & Prototyping

• Reverse engineer web and mobile applications to identify and extract accessible data points.
• Intercept and analyze network traffic using tools such as Burp Suite, mitmproxy, or Frida to understand client-server interactions.
• Build proof-of-concept scrapers and automation scripts in Python 3.9+ to validate the viability of OSINT data sources.
• Use proxy infrastructure (residential, datacenter, rotating) to conduct distributed, anonymized research at scale.

Collaboration and Impact

• Partner closely with software engineers to refine and productionize successful research findings into high-throughput data enrichment services.
• Proactively contribute to improving SEON’s data-gathering platform by identifying new sources and more efficient data extraction methods.
• Participate in technical design discussions related to crawler architecture and OSINT pipelines.

What you'll bring:

• Strong hands-on experience with Python 3.9+, including libraries for HTTP requests, asynchronous workflows, scraping, and automation.
• Proven web and mobile reverse engineering skills, including traffic interception, request signature decoding, and anti-bot circumvention.
• Familiarity with tools like Burp Suite, mitmproxy, Frida, or similar for debugging and traffic inspection.
• Experience using cyber intelligence platforms and mining publicly available data (including open forums, leaks, or search engines).
• Knowledge of fraud tactics and a keen interest in understanding threat actors and their digital footprints.
• A strong analytical mindset and creative problem-solving skills.
• Excellent communication skills in English (written and spoken).

Nice to have:

• Prior experience in structured OSINT investigations or cyber threat research.
• Contributions to open-source OSINT tools, projects, or participation in relevant communities.
• Background in penetration testing, bug bounty programs, or ethical hacking.
• Familiarity with AWS services (Lambda, S3, etc.) and infrastructure automation.
• Experience with automation frameworks and/or OSINT-specific platforms like Maltego, Spiderfoot, or Recon-ng.
