The posting

McKesson is an impact-driven, Fortune 10 company that touches virtually every aspect of healthcare. We are known for delivering insights, products, and services that make quality care more accessible and affordable. Here, we focus on the health, happiness, and well-being of you and those we serve – we care.

What you do at McKesson matters. We foster a culture where you can grow, make an impact, and are empowered to bring new ideas. Together, we thrive as we shape the future of health for patients, our communities, and our people. If you want to be part of tomorrow’s health today, we want to hear from you.

McKesson is seeking a Senior Information Security Analyst, Vulnerability Disclosure and External Attack Surface Management to help protect our externally accessible technology through a mature Vulnerability Disclosure Program and External Attack Surface Management capability.

In this role, you will manage reports from security researchers, assess externally observable vulnerabilities, discover internet-facing assets, and coordinate remediation across security, engineering, cloud, infrastructure, legal, and business teams. You will apply technical judgment to determine whether reported vulnerabilities are valid, exploitable, and material to the business.

This is a senior individual-contributor role for someone who can independently lead sensitive investigations, improve cybersecurity processes, and influence remediation without direct authority. You will work across cloud, software-as-a-service, web application, API, identity, network, DNS, email, and certificate environments.

What You'll Do

  • Operate and improve the Vulnerability Disclosure Program, including researcher intake, report triage, validation, communications, case documentation, remediation coordination, and closure.
  • Lead External Attack Surface Management activities to discover and monitor domains, subdomains, IP addresses, ports, services, certificates, DNS records, cloud resources, applications, APIs, and third-party technologies.
  • Evaluate reports for validity, duplication, severity, exploitability, affected scope, business impact, and remediation priority.
  • Safely validate externally observable vulnerabilities using authorized testing methods and established security assessment tools.
  • Coordinate remediation and exception management with engineering, cloud, infrastructure, application, legal, and business stakeholders.
  • Analyze complex data sets, reconcile conflicting asset ownership information, identify exposure patterns, and translate findings into actionable recommendations.
  • Maintain accurate evidence, decisions, communications, remediation status, metrics, and audit-ready program records.
  • Improve standards, workflows, reporting, automation, and governance for vulnerability disclosure, attack surface management, and enterprise vulnerability management.

Basic Requirements

  • 7+ years of progressive cybersecurity experience, including vulnerability management, security engineering, application security, penetration testing, attack surface management, or a related discipline.
  • Demonstrated experience operating or supporting a Vulnerability Disclosure Program, bug bounty program, coordinated vulnerability disclosure process, or security researcher intake function.
  • Experience with External Attack Surface Management, internet-facing asset discovery, or continuous monitoring of externally accessible technology.
  • Experience validating vulnerabilities and assessing severity, exploitability, affected scope, business impact, remediation priority, and duplicate submissions.
  • Working knowledge of CVSS, CWE, CVE, the OWASP Top 10, and common web application, API, cloud, network, identity, DNS, email, or certificate exposures.
  • Experience investigating domains, IP addresses, services, certificates, DNS records, cloud resources, applications, APIs, and third-party technologies.
  • Experience using vulnerability management, ticketing, asset inventory, configuration management, SIEM, threat intelligence, or governance, risk, and compliance platforms.
  • Bachelor’s degree in cybersecurity, computer science, information systems, engineering, or a related field, or an equivalent combination of education and relevant experience.

Preferred Skills/Experience

  • Knowledge of coordinated vulnerability disclosure guidance, including ISO/IEC 29147 and ISO/IEC 30111.
  • Experience with recognized bug bounty or vulnerability disclosure platforms and External Attack Surface Management technologies.
  • Understanding of cloud and hybrid environments, including externally accessible resources in major cloud and software-as-a-service platforms.
  • Experience automating asset discovery, data enrichment, case management, vulnerability correlation, or reporting workflows.
  • Ability to analyze large data sets, identify patterns, and reconcile incomplete or conflicting asset information.
  • Strong written and verbal communication skills for working with security researchers, engineers, executives, legal partners, and nontechnical asset owners.
  • Demonstrated ability to influence remediation and program improvements across teams without direct management authority.
  • Strong judgment, attention to detail, and ability to manage multiple high-priority or sensitive investigations independently.

Travel / Work Environment / Physical Requirements

  • Work arrangement, office attendance, and travel expectations will be communicated based on the position’s approved location and business requirements.
  • Occasional travel or participation in scheduled incident, escalation, or stakeholder activities may be required.
  • The role involves extended computer use and virtual or in-person collaboration across geographically distributed teams.
  • Reasonable accommodations may be provided in accordance with applicable requirements

Why it works

3×

more interviews than doing it yourself with ChatGPT.

ChatGPT writes a CV and never learns what happened to it. We see every reply. For each CV we know:

  • How it was written, and how the review scored it
  • When we applied, and how long after the posting went up
  • Which posting, which company, which city
  • Who got the interview, and who heard nothing

That is how we know which CVs get called.
