Company Name: Symbiotic Security
Job Title: Cybersecurity Researcher
Job Description: **Job Title** Cybersecurity Researcher **Role Summary** Conduct proactive security research on public code repositories, identify novel vulnerability classes, and develop practical mitigation artifacts (PoCs, AST transforms, linters, static rules, LLM‑assisted remediations). Translate findings into product features, developer workflow integrations, and educational content while maintaining responsible disclosure practices. **Expectations** - 2–3 years of cybersecurity or research experience. - Master’s degree in Computer Science or related field. - Proficiency in multiple programming languages and software architecture concepts. - Portfolio evidence of CTF participation, vulnerability discovery, or relevant research outputs. - French B2 level required; professional English proficiency essential. - Comfortable working in agile development environments and collaborating cross‑functionally. **Key Responsibilities** 1. Research and discover new vulnerability classes in public repositories using automated analysis tools. 2. Build reproducible Proof‑of‑Concepts demonstrating attacks and prototype protections (AST transforms, linters, static rules, LLM‑assisted remediation). 3. Design and implement detection rules integrated into developer workflows (IDE extensions, CI pipelines). 4. Produce technical write‑ups, blog posts, disclosure advisories, and event slide decks. 5. Design concise, portable Capture‑The‑Flag challenges and demo content for conferences (e.g., DEFCON). 6. Collaborate with product and engineering teams to turn research into usable product features and training modules. 7. Maintain responsible disclosure processes for findings impacting third parties or customers. **Required Skills** - Advanced code analysis and exploitation techniques. - Proficiency in scripting/compiled languages (e.g., Python, Go, JavaScript, Rust, C/C++). - Experience building AST‑based transformations, linters, and static analysis rules. - Familiarity with LLMs for security remediation (optional but preferred). - Strong written and verbal communication for technical documentation and public presentations. - Knowledge of Agile/Scrum methodologies. - Bilingual proficiency: French (B2+) and English (professional). **Required Education & Certifications** - Master’s degree in Computer Science, Information Security, Software Engineering, or equivalent. - Relevant cybersecurity certifications (e.g., OSCP, CEH, CISSP, or equivalent) preferred but not mandatory.
