Vulnerability Analyst External Attack Surface & VDP

Were 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). Youll 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)

What youll 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.

Deduplicate, 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 isnt feasible.

Partner on governance workflows ?for 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 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 youll bring

35 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 exposed service hardening.

Scripting ?(Python / PowerShell / Bash) for repeatable validation and data wrangling; basic SQL helpful.

Exceptional written communicationcapable 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.

Whats in it for you

A front row seat reducing real-world external riskturning noisy findings into? decisive action .

Growth pathways into? pen testing ,? threat modeling / assurance , or? VM program leadership .
