Vulnerability Analyst External Attack Surface & VDP

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 .
