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.
