             What you’ll do + Validate & reproduce findings from EASM ( internet exposed assets, misconfigurations, leaked services, weak crypto, open ports) and from VDP submissions (web, API, mobile, infrastructure). Use manual techniques and PT frameworks to confirm exploitability and business impact. + Right - size severity & priority using exploitability signals (e.g., public exploit, EPSS/KEV), control context, asset criticality, and exposure window; document rationale and evidence that developers and risk owners can act on. + De duplicate, enrich & route findings to the correct owners; eliminate false positives; merge related signal (scanner output, logs, asset inventory, prior exceptions) and ensure single threaded tracking to closure. + Partner with secure business enablement & product teams to negotiate remediation paths and SLAs; propose compensating controls or layered fixes when “ one-shot ” remediation isn’t feasible . + Partner on governance workflows for risk acceptances, rating overrides, and re acceptance cycles; ensure issues aging and SLAs are visible in our dashboards. + Close the loop with researchers (for VDP) through clear, respectful communications and crisp proof - of - fix retesting. + Continuously improve signal quality by tuning rules/policies, source inventories, and intake/playbooks; author repeatable runbooks for common vuln classes. + Contribute as an adversary when needed ( mini - engagements ) to validate edge case chains and confirm impact beyond tool output. What you’ll bring + 3 – 5 years in vulnerability analysis, application/infrastructure security, red teaming, or penetration testing (internal or consulting). + Proven ability to validate complex issues (param tampering, authN /Z bypass, SSRF, injection, IDOR, misconfig , cloud/API exposures) and write concise, repeatable steps with screenshots/ PoCs . + Experience with EASM (e.g., Censys , Defender EASM, Cortex Xpanse ) and VDP/bug bounty platforms (e.g., HackerOne , Bugcrowd ) and their triage mechanics. + Familiarity with enterprise VM & tracking (ServiceNow VR/IRM, Jira, Archer/Risk Register), and with platform scanners (Qualys/ Tenable/ Nessus/Burp/ZAP). + Working knowledge of cloud (AWS/Azure), web & API security, PKI/TLS hygiene, DNS, and internet e xposed service hardening. + Scripting (Python/PowerShell/Bash) for repeatable validation and data wrangling; basic SQL helpful. + Exceptional written communication—capable of translating technical risk into actionable guidance and executive clarity. Nice - to - have exposure + EPSS/ KEV driven prioritization, attack path/graph concepts, and risk quant inputs. + Cloud posture and SaaS posture signals (SSPM) that intersect with external exposure. + Building tuning logic for scanners and platform rules (e.g., policy libraries, discovery seeds, asset correlation). + Certifications such as OSCP , GWAPT , GPEN (or equivalent demonstrable skill) are a plus; CISSP nice - to - have. What’s in it for you + A front row seat reducing real-world external risk—turning noisy findings into decisive action . + Growth pathways into pen testing , threat modeling/assurance , or VM program leadership .
