About TuxCare
TuxCare provides security solutions for Linux and open-source software used by enterprise organizations. Our products help companies automate vulnerability patching, reduce downtime, maintain security and compliance, and support critical systems throughout their lifecycle. We are looking for a Senior / Principal Security Research Engineer to start the Security Research & Automation function of SecureChain.
Responsibilities
•Detect malicious code before SecureChain publishes a package.
•Build pipelines that find and help fix high and critical vulnerabilities in maintained and end-of-life open-source software.
•Publish useful, evidence-backed security research after coordinated disclosure.
•Owning SecureChain's malicious-code detector: alert review and classification, test corpus, quality benchmarks, false-positive and coverage metrics.
•Extending detection with artifact scanning, static signals, dynamic analysis and external intelligence.
•Building repeatable pipelines that discover new vulnerabilities in software that SecureChain and ELS support, with priority on high/critical risks and on EOL versions customers still use.
•Reproducing findings, proving impact and reachability, and storing evidence so another researcher can repeat the result.
•Developing AI-assisted methods to generate and test candidate fixes, and feeding them into our patch automation.
•Owning TuxCare CNA work: CVE assignment, record quality and coordinated disclosure with upstream projects.
•Preparing technical write-ups and research publications together with Marketing.
Requirements
•Security research background: malware or software supply-chain research, vulnerability discovery and root-cause analysis.
•Strong Python or another suitable systems language; you build tools and pipelines that run in production.
•CI pipelines, test automation and operating services.
•Practical use of static analysis, fuzzing and sandboxing.
•Heavy, daily use of AI-assisted tools in research and engineering.
•Experience with more than one package ecosystem (e.g. PyPI, npm, Maven, Go, Linux distributions).
•Clear research reports and experience with coordinated disclosure.
•Advanced written and spoken English.
Nice to have
•Published CVEs, advisories or security research.
•Experience with CNA operations or vulnerability databases (CVE, OSV).
Conditions
•A focus on professional development.
•Interesting and challenging projects.
•Fully remote work with flexible working hours, that allows you to schedule your day and work from any location worldwide.
•Paid 24 days of vacation per year, 10 days of national holidays, and unlimited sick leaves.
•Compensation for private medical insurance.
•Co-working and gym/sports reimbursement.
•Budget for education.
•The opportunity to receive a reward for the most innovative idea that the company can patent.
