Senior Application Security Researcher

This is a fully remote position, open to applicants in Poland.

📋 Description

• Advance modern application security through active security research.

• Collaborate with engineers, researchers, and AI/data scientists on cutting-edge detection methodologies.

• Create autonomous, agent-based penetration testing capabilities.

• Construct and dismantle security systems instead of fulfilling a conventional AppSec role.

• Transition research concepts from prototype stage to production.

⛳️ Requirements

• Over 5 years of hands-on experience in offensive security, vulnerability research, or application security.

• Profound knowledge of web application and API vulnerabilities, including business logic flaws and multi-step attack sequences.

• Proficient coding skills in Python, Go, or similar languages, with experience delivering production-quality code.

• Experience in building or fine-tuning detection logic (SAST, DAST, SCA, secrets, or custom rule engines) and minimizing false positives.

• Practical experience using LLMs / AI models for security applications, with the ability to assess their effectiveness and limitations.

• Familiarity with large datasets (SQL, BigQuery, or equivalent) to support research and evaluate detection accuracy.

• Capable of taking research ideas from prototype to production with minimal supervision.

• Excellent written communication skills — able to convey complex attack pathways to engineers and product managers.

• Master’s degree in Computer Science, Cyber Security, or a related discipline.

• A record of published research, CVEs, conference presentations, or bug bounty achievements.

• Experience in developing AI agents or evaluation frameworks for LLMs.

• Background in exploit development, red teaming, or penetration testing.

• Proficiency in code analysis techniques (taint analysis, call graphs, reachability).

• Contributions to open-source security tools.
