How to Write a Detection Engineer Resume (2026 Guide With Examples)

A detection engineer resume that just says "I write alerts" gets filtered out. When employers screen detection engineers, they look for one thing: can you build detection logic that catches real threats, maps to known techniques, and stays tuned so analysts aren't drowning in noise. A resume that wins interviews speaks in detection logic, SIEM, and ATT&CK coverage. Here is how to write it.

What a detection engineer must prove

• Detection logic: detection rules, analytics, queries, detection-as-code.
• SIEM/tooling: SIEM (Splunk, Elastic, Sentinel), EDR, data sources, pipelines.
• ATT&CK coverage: mapping detections to MITRE ATT&CK, coverage gaps, threat-informed.
• Tuning & quality: false-positive reduction, fidelity, testing, detection validation.

In one line: your resume should answer "what detections did you build, what techniques do they cover, and how did you tune them for fidelity."

Don't just say "I write alerts," show detections and coverage

Use concrete outcomes and quantify them:

• ❌ "Created security alerts" — shows nothing.
• ✅ "Detection engineer — built and maintained detection rules in the SIEM mapped to MITRE ATT&CK, expanded coverage of priority techniques, tuned detections to cut false positives, and validated them with testing/detection-as-code" — detection logic, SIEM, ATT&CK, and tuning.

Things you can quantify: detections / coverage, ATT&CK techniques, false-positive reduction, data sources / validation. For methods, see how to quantify resume achievements. Keep claims honest — real coverage and fidelity, no inflation.

How to write the skills section

Group your detection engineering skills so a reviewer can scan them:

• Detection logic: detection rules, analytics, queries (SPL/KQL), detection-as-code
• SIEM & tooling: Splunk, Elastic, Sentinel, EDR, data sources, log pipelines
• Threat-informed: MITRE ATT&CK mapping, threat intelligence, coverage analysis
• Tuning & testing: false-positive reduction, fidelity, validation, CI for detections
• Collaboration: SOC, incident response, threat intel, purple teaming

For structure, see how to list skills on a resume. Detection engineers should especially highlight ATT&CK coverage and tuning — the bar beyond "wrote alerts."

Detection engineer vs SOC analyst

These roles overlap, so make your focus clear:

• Detection engineer: builds the detections — engineering rules, coverage, and fidelity.
• SOC analyst: see how to write a SOC analyst resume, operates them — monitoring, triaging, and investigating the alerts, not building them.

If you span both, say so, but lead with building detections. Related roles: IAM engineer, red team engineer. Tailor to the target with how to tailor your resume to a job description.

Common mistakes

• "Alerts" with no logic: detection rules and analytics are the core — surface them.
• No ATT&CK: mapping to MITRE ATT&CK shows threat-informed coverage, not random alerts.
• No tuning: false-positive reduction is half the job — analysts drown without it.
• No validation: testing/detection-as-code shows you treat detections as engineering.
• Vague claims: "wrote alerts" loses to "built ATT&CK-mapped detections, expanded coverage, tuned out false positives, validated with testing."

Frequently Asked Questions

What should a detection engineer resume highlight?

Detection logic, SIEM, ATT&CK coverage, and tuning. Use detection/coverage, ATT&CK-technique, false-positive, and data-source data to prove what detections you built, what they cover, and how you tuned them — not just "I write alerts."

How do I quantify a detection engineer resume?

Use real data: detections and coverage, ATT&CK techniques, false-positive reduction, data sources and validation. For example, "built ATT&CK-mapped detections, expanded coverage, tuned out false positives, validated with testing" says far more than "created security alerts." Keep claims honest.

How is a detection engineer resume different from a SOC analyst's?

A detection engineer builds the detections — engineering rules, coverage, and fidelity; a SOC analyst operates them — monitoring, triaging, and investigating alerts. One builds, the other operates. Position your resume by your focus and lead with building detections.

Should a detection engineer resume mention MITRE ATT&CK?

Yes. ATT&CK is the standard way to express detection coverage in threat-informed terms, so mapping your detections to techniques (and showing coverage you added) signals modern, intentional detection engineering — far more than a count of alerts. Pair it with tuning and validation.
