As a Senior Threat Intelligence Researcher, you'll lead deep-dive investigations into both emerging & known threats, while maintaining a vigilant watch over malware developments to ensure defenses remain a step ahead of evolving attack methods. You'll put into use your ability to synthesize complex data into actionable intelligence, and to provide senior management with the clear briefings necessary to understand and mitigate potential risks. Furthermore, you'll be expected to develop refined hunting strategies (to adapt to and anticipate shifts in threat actor tactics & techniques), and to track adversary infrastructure, effectively counteracting shifts in threat actor tactics through detail-oriented investigation.

What Will You Do? 

Primary responsibilities include:

• Drive External Threat Research: Triage and evaluate findings from OSINT and lead in-depth investigations into emerging threats. Systematically evaluate signals from the global OSINT community and dark web forums to determine their fidelity, relevance, and impact.
• Synthesize Actionable Intelligence: Transform raw data from dark web forums, leak sites, and research repositories into high-level threat briefings and risk assessments for senior stakeholders.
• Adversary Knowledge Management: Curate and expand our internal Knowledge Base and IOCs collections.
• Track Actor Tradecraft (TTPs): Monitor adversary behaviors across the open and deep web to identify shifts in recruitment, target selection and shifting of operations.
• Pivot Across Infrastructure: Identify and map threat actor footprints by pivoting through domain registrations, SSL certificates, passive DNS.
• Bridge Intelligence Gaps: Collaborate closely with Detection Engineering to translate validated OSINT findings into durable hunting logic.
• Develop OSINT Tooling: Build and automate scrapers, monitors, and data-visualization tools to identify anomalies and track threats in external telemetry.
• Working setup: Flexible working hours, this is a 100% remote role on full-time permanent employment (UoP) based within Poland. We provide optional membership in major coworking chains. Currently for this role in Poland we are able to consider only candidates that are already eligible to work in the EU at the time of applying. Optionally for those willing to relocate to the Czech Republic relocation assistance is available for any candidates that are already eligible to work in the EU at the time of applying.

What Skills and Knowledge Will You Bring?

Ideal candidates will have:

• Must haves
• A Threat Intelligence / Threat hunting background.
• Knowledge of the cyber threat landscape, including actors and TTPs.
• Strong analytical skills, with the ability to identify patterns and trends in large datasets.
• Programming skills in python and knowledge of databases (SQL, noSQL)
• Strong knowledge of YARA to track new malware families and knowledge on validation best practices.
• Knowledge of MITRE ATT&CK, CISA KEV, EPSS, AMITT, MISP Galaxy.
• Strongly preferred
• Knowledge of malware analysis tools and techniques, including static and dynamic analysis, sandboxing, and debugging. 
• Technical writing & content development skills.
• Nice to have
• Understanding software vulnerabilities, and ability to implement hunting strategies to track and discover them.
• Knowledge about internal working of EDR products.
• Relevant certifications, such as Certified Malware Analyst (CMA), Certified Reverse Engineering Analyst (CREA), or GIAC Certified Malware Reverse Engineer (GREM)
