Vulnerability Analyst — External Attack Surface & VDP

We’re seeking a hands-on Vulnerability Analyst to validate, analyze, and prioritize vulnerabilities discovered across our External Attack Surface Management (EASM) platform and Vulnerability Disclosure Program (VDP). You’ll combine deep vulnerability analysis with adversarial testing skills to reproduce and triage issues, ensure accurate severity and ownership, and drive timely remediation with partner teams. The ideal candidate has strong diagnostic instincts, excellent written evidence construction, and practical penetration testing experience. *This Hybrid Role (in office Tues-Wed-Thurs) can be based in either Charlotte, NC, Dallas, TX, or Malvern, PA (HQ)** Whatyou’lldo • Validate & reproduce findingsfrom 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-sizeseverity & priorityusing 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. • Deduplicate, enrich & routefindings 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 withsecure business enablement& productteamsto negotiate remediation paths and SLAs; propose compensating controls or layered fixes when “one-shot” remediation isn’t feasible. • Partner ongovernance workflowsfor risk acceptances, rating overrides, and reacceptance 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 qualityby tuning rules/policies, source inventories, and intake/playbooks; author repeatable runbooks for common vuln classes. • Contribute as an adversarywhen needed (mini-engagements) to validate edge case chains and confirm impact beyond tool output. Whatyou’llbring • 3–5yearsin vulnerability analysis, application/infrastructure security, red teaming, or penetration testing (internal or consulting). • Proven ability tovalidatecomplex issues(param tampering, authN/Z bypass, SSRF, injection, IDOR, misconfig, cloud/API exposures) and write concise, repeatable steps with screenshots/PoCs. • Experience withEASM(e.g., Censys, Defender EASM, Cortex Xpanse) andVDP/bug bountyplatforms (e.g., HackerOne, Bugcrowd) and their triage mechanics. • Familiarity withenterprise VM & tracking(ServiceNow VR/IRM, Jira, Archer/Risk Register), and with platform scanners (Qualys/Tenable/Nessus/Burp/ZAP). • Working knowledge ofcloud(AWS/Azure),web & APIsecurity, PKI/TLS hygiene, DNS, and internet exposed service hardening. • Scripting(Python/PowerShell/Bash) for repeatable validation and data wrangling; basic SQL helpful. • Exceptional written communication—capable of translating technical risk intoactionable guidanceand 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 asOSCP,GWAPT,GPEN(or equivalent demonstrable skill) are a plus;CISSPnice-to-have. What’sin it for you • A front row seat reducing real-world external risk—turning noisy findings intodecisive action. • Growth pathways intopen testing,threat modeling/assurance, orVM program leadership.
