Summary

Security engineer with 6 years of experience building and operating detection and response programs that protect cloud-native infrastructure at scale. At CrowdStrike, led the development of custom SIEM detection rules that reduced mean time to detect from 72 hours to under 4 hours, directly supporting the company’s managed detection and response offering. Deep expertise in Splunk, penetration testing, and cloud security across AWS and GCP, with a track record of reducing vulnerability remediation timelines, achieving SOC 2 compliance, and preventing security incidents before they reach production.

Experience
Senior Security Engineer Mar 2024 – Present
CrowdStrike Austin, TX
  • Built 40+ custom detection rules in Splunk and Microsoft Sentinel that identified 3 previously undetected lateral movement patterns, reducing mean time to detect from 72 hours to under 4 hours across 12,000+ monitored endpoints
  • Led incident response for 8 critical security events including a ransomware attempt and supply chain compromise, containing all incidents within 2 hours and achieving zero data exfiltration across all engagements
  • Designed and implemented a zero trust architecture for internal services using BeyondCorp principles, eliminating VPN dependency for 400+ employees and reducing the attack surface by 65%
Security Engineer Jun 2021 – Feb 2024
Cloudflare San Francisco, CA
  • Conducted quarterly penetration tests across 6 customer-facing applications, identifying 47 vulnerabilities including 4 critical findings, and reduced average remediation time from 30 days to 8 days by embedding security reviews into the CI/CD pipeline
  • Led the SOC 2 Type II certification program, coordinating across engineering, legal, and compliance teams to close 23 control gaps and achieve certification 6 weeks ahead of schedule
  • Built an automated vulnerability management pipeline in Python that triaged 2,000+ CVEs monthly, prioritizing by exploitability and business context, reducing false-positive alerts by 74%

What makes a strong cybersecurity engineer resume

Lead with incidents prevented, not tools operated

Every security engineer can list Splunk, Sentinel, and Burp Suite. What separates a strong resume is showing the threats you actually caught and the damage you prevented. “Monitored SIEM alerts” tells a hiring manager nothing. “Built 40+ custom detection rules that identified 3 previously undetected lateral movement patterns, reducing mean time to detect from 72 hours to under 4 hours” tells them you think about adversary behavior, not just dashboard management. The best cybersecurity resumes quantify detection rates, response times, remediation timelines, and incident outcomes — because those are the numbers that define whether a security program actually works.

Show that you prevent incidents, not just respond to them

Incident response is table stakes for security engineers. Hiring managers at companies like CrowdStrike, Palo Alto, and Cloudflare are specifically looking for engineers who shift security left — catching vulnerabilities in CI/CD pipelines, embedding threat modeling into design reviews, and building automated triage systems that reduce noise. If you’ve reduced remediation timelines, built vulnerability management automation, or implemented zero trust architecture, those accomplishments deserve prominent placement. They signal that you understand proactive security — not just reactive firefighting.

Vulnerability remediation rates are your highest-leverage bullet point

Reducing remediation time from 30 days to 8 days is instantly understood by any security hiring manager. It implies you built processes, partnered with engineering teams, and embedded security into existing workflows rather than creating bottlenecks. If you’ve improved patching cadence, reduced false-positive rates, or automated vulnerability triage, lead with the before/after numbers. They’re more compelling than any description of tools you’ve used.

Compliance achievements demonstrate cross-functional leadership

Junior security engineers focus on finding vulnerabilities. Senior security engineers focus on building programs that scale. Showing that you led a SOC 2 certification, closed control gaps across multiple teams, or designed governance frameworks signals to a hiring manager that you can operate at the organizational level — not just the terminal. “Led SOC 2 Type II certification and achieved it 6 weeks ahead of schedule” isn’t just a compliance accomplishment; it’s proof you can coordinate across engineering, legal, and leadership. Don’t underestimate the impact of program-level work on your resume.

Frequently asked questions

Should I list every security certification I have?
No. List the 2–3 certifications most relevant to the role you’re applying for. If the job posting asks for CISSP and you have it, put it front and center. But listing 8 entry-level certs you earned five years ago dilutes the signal and makes you look like a credential collector rather than a practitioner. Prioritize certifications that match the seniority and focus area of the role — and drop anything you couldn’t discuss in depth during a technical interview.
How do I show threat detection experience without revealing sensitive details?
Focus on the scale, the methodology, and the outcome — not the specific threat actor or vulnerability. “Built custom SIEM detection rules in Splunk that identified 3 previously undetected lateral movement patterns, reducing mean time to detect from 72 hours to under 4 hours” tells the story without disclosing anything sensitive. You can describe the type of attack, the tools you used, and the measurable improvement without naming clients, systems, or classified details.
Should I include CTF competitions or bug bounty work on my resume?
Only if you have notable results and they’re relevant to the role. Ranking in the top 10 at DEF CON CTF or earning $50K+ in verified bug bounties demonstrates real offensive security skill that’s hard to fake. But listing every CTF you’ve ever entered or minor bug bounty findings adds noise without signal. Pick 1–2 achievements that show depth in the specific security domain the job requires, and leave the rest for your portfolio or LinkedIn.
