The Detection Engineering Lead is a hands-on professional responsible for owning detection engineering for a large US consumer lender whose 24/7 security operations run from AspenView’s secure offices in Bogotá and Buenos Aires. Telemetry from CrowdStrike, Microsoft Defender, Okta, Palo Alto, Proofpoint and AWS flows through Abstract Security into Elastic, and alerts become ServiceNow cases. You will be responsible for what gets detected along that chain, and for proving it. Based in Bogotá or Buenos Aires, in a hybrid model, you will lead the team’s Detection Engineering Analysts, set priorities, review every rule and decide what goes to the client for approval, working closely with the threat hunting team. You will report to the SOC Manager and present detection coverage directly to the client’s security leadership.

What you will do:

Detection Lifecycle & Prioritization

- Own the detection inventory end to end, including new use cases, tuning, health monitoring and retirement, each with a clear owner.
- Prioritize detection work based on threat intelligence, hunt findings, incidents and Tier 2 feedback,



focusing on the techniques that matter most to a consumer lender.
- Build identity-centric detections on Okta, custom detections in CrowdStrike and Microsoft Defender, and AWS control-plane coverage.

Pipeline Health & Troubleshooting

- Troubleshoot the full telemetry chain end to end, from data reaching Abstract but not Elastic to alerts that fire but never become ServiceNow cases.
- Make sure the data feeding detections is parsed, normalized and enriched correctly.

Detection as Code & Reporting

- Run detection as code, with version control, peer review, testing against simulated attacks, and change records the client approves before alerting behavior changes.
- Produce MITRE ATT&CK; coverage reporting for the client’s security leadership, gaps included.
- Lead, mentor and review the work of the Detection Engineering Analysts, and turn threat hunting findings into production detections.

Tools & Technologies:

- SIEM & Detection: Elastic Security (EQL, ES|QL, KQL); Splunk, Sentinel, Google SecOps or QRadar also relevant.
- Data Pipeline: Abstract Security, or equivalents such as Cribl.
- Endpoint, Identity & Cloud: CrowdStrike Falcon, Microsoft Defender, Okta System Log, AWS CloudTrail and GuardDuty.
- Case Management: ServiceNow SecOps integration and alert routing.
- Testing & Automation (Bonus): Sigma, YARA,



Atomic Red Team, Caldera, Python and SOAR playbooks.

What you bring:

- Experience: 5+ years writing and tuning detections in production on a SIEM or analytics platform, with the ability to explain the reasoning behind a rule you shipped. Solid understanding of log pipelines, including where data goes missing between source and alert.
- Engineering Discipline: You treat detections as code, with version control, peer review and testing before release. You can tell a client what a rule catches, what it misses and how you know.
- Communication / Leadership: Hands-on experience mentoring engineers and reviewing their work, even without a formal lead title. Fluent English (B2+/C1), strong enough to present coverage, gaps included, to a client’s security leadership without an intermediary.
- Availability: Full-time, as a direct AspenView employee dedicated to one client, in a hybrid model based in Bogotá or Buenos Aires: two days a week in AspenView’s office and three from home, plus in-person attendance for important meetings. US Eastern business hours, with no on-call rotation. The client’s systems are accessed only through its VDI, and access requires identity, criminal background, employment and education checks, repeated periodically.
- Bonus Qualifications: Hands-on Elastic Security (the most valuable extra on this stack); Abstract Security or Cribl; custom IOAs in CrowdStrike Falcon and advanced hunting in Microsoft Defender; financial services experience under NYDFS Part 500, SOX or PCI DSS; applying GenAI to detection work with evaluation behind it; and GCDA, GCIA, GCED, SC-200 or Elastic certifications.
