Responsibilities
We are looking for a Security Analyst to join our security research team. You will work hands-on with web application vulnerabilities every day, assessing findings, confirming exploitability, rating severity, and delivering clear, accurate reports that customers rely on to understand and remediate their risk.
This role does not require software engineering experience. It requires deep familiarity with web vulnerabilities, sharp analytical judgment, and the ability to communicate findings precisely. If you have spent time in bug bounty, application security, or pentesting and have a strong eye for what is real and what is noise, we want to hear from you.
Assess and validate web application vulnerabilities across a range of targets and confirm exploitability and scope
Reproduce findings hands-on using tools like Burp Suite
Rate severity accurately using established frameworks such as CVSS and OWASP
Write clear, accurate, customer-facing finding descriptions and remediation guidance that security practitioners trust and developers can act on
Maintain consistent standards across a high volume of findings
Surface patterns, edge cases, and unusual behaviors to the broader team
Identify patterns across findings and share feedback on where and how Sybil can improve
