Atyeti - Senior Detection Engineer

Job Description :

Job Responsibilities :

Detection Engineering (Primary Focus) :

- Design, develop, and maintain high-fidelity detection rules and analytics across CrowdStrike Falcon (NGSIEM/EDR) and integrated SIEM platforms.

- Translate threat intelligence and adversary behaviors (MITRE ATT&CK) into scalable detection use cases.

- Continuously tune and optimize detections to improve alert fidelity and signal-to-noise ratio.

- Develop and maintain detection-as-code practices, including version control, testing, and documentation.

- Perform coverage gap analysis and proactively build new detections to address emerging threats.

- Partner with threat hunting teams to convert hypotheses into production-grade detections.

- Validate detection coverage through purple teaming, adversary simulation, and attack replay testing.

- Build detection strategies across :

i. Endpoint (EDR)

ii. Identity

iii. Network and OT telemetry

iv. Cloud environments

SOAR Engineering & Automation (Secondary Focus) :

- Design and implement automated playbooks using CrowdStrike Falcon Fusion and/or SOAR platforms.

- Automate end-to-end incident response workflows, including :

i. Alert triage and enrichment

ii. Threat intelligence correlation

iii. Endpoint containment and remediation

iv. Case management and escalation

- Integrate SOAR with SIEM, EDR (CrowdStrike), NDR, vulnerability management, and threat intelligence platforms.

- Develop and maintain API-based integrations and connectors across security tools.

- Ensure automation workflows are resilient, auditable, and governed.

- Continuously identify opportunities to reduce manual SOC effort through orchestration.

Operational Mentality and SOC Optimization :

- Champion a detection-first SOC model supported by automation.

- Improve SOC workflows through automated enrichment, triage, and response actions.

- Collaborate with SOC analysts, threat hunters, and engineers across APAC.

- Enhance operational metrics such as :

i. Mean Time to Detect (MTTD)

ii. Mean Time to Respond (MTTR)

iii. Alert fidelity and reduction of false positives

OT & R&D Security Strategy :

- Develop detection and response use cases tailored for OT/ICS, SCADA, and IIoT environments.

- Collaborate with engineering and R&D teams to integrate detect-and-respond capabilities into product lifecycles.

- Align detection strategies with :

i. MITRE ATT&CK (Enterprise & ICS)

ii. NIST CSF / NIST 800-82

iii. IEC 62443

- Ensure safe implementation of automation within sensitive OT environments.

Job Qualifications :

Required Qualifications & Experience :

- 7+ years of experience in cybersecurity with a focus on detection engineering, SOC operations, or incident response.

- 3+ years of hands-on experience in :

i. Detection engineering / SIEM content development

ii. SOAR platforms (CrowdStrike Falcon Fusion preferred)

iii. Strong experience with CrowdStrike Falcon (EDR + NGSIEM)

- Proven experience building detection rules, behavioral analytics, and correlation logic.

- Proficiency in scripting and automation (Python, PowerShell, or similar).

- Experience with detection-as-code and API integrations.

- Strong understanding of :

i. MITRE ATT&CK (Enterprise & ICS)

ii. Threat detection methodologies

iii. Incident response lifecycle

- Hands-on experience with SIEM, EDR, NDR, and threat intelligence platforms.

- Foundational knowledge of IT and OT security (ICS/SCADA environments).

- Experience securing R&D environments and intellectual property.

- Working knowledge of cloud security (AWS, Azure, GCP).

Desired Certifications :
