About the role

What You'll Do

  • Design high-fidelity detections and correlation logic in Splunk Enterprise Security and AWS OpenSearch — tuning for coverage and signal-to-noise.
  • Build AI-powered detection tooling that ingests threat intel and recommends new use cases using ML and NLP techniques.
  • Write production Python, Java, and Bash to automate workflows, build internal tooling, and integrate with cloud and third-party APIs.
  • Engineer ETL pipelines for log ingestion, normalization, and routing across AWS, multi-cloud, and on-prem environments.
  • Translate red team findings, threat hunts, and pentest results into durable detection improvements and control enhancements.
  • Drive detection standards and reusable patterns across endpoint, network, identity, and cloud domains.
  • Mentor engineers and analysts on detection methodology, secure software practices, and architecture.

What You Have

  • Bachelor's degree in Computer Science, Cybersecurity, or a closely related technical field (Master's a plus).
  • 6+ years in software and/or security engineering, with 2+ years building detections on enterprise SIEMs (Splunk, OpenSearch, Securonix, or equivalent).
  • 2+ years hands-on experience developing security automation or AI/ML-based security applications in Python, Java, or similar.
  • Strong command of AWS (SageMaker, OpenSearch, Lambda, IAM), EDR platforms (CrowdStrike, Carbon Black), and modern identity tooling.
  • Fluency with MITRE ATT&CK, NIST CSF, Zero Trust, and CIS Controls; comfort integrating STIX/TAXII and MISP feeds.
  • Track record supporting compliance audits (SOC 2, FedRAMP, ISO 27001, HIPAA, or SOX) from a hands-on engineering seat.

Nice to Have

  • Splunk Certified Architect or Developer; CISSP, CEH, or GIAC GCED.
  • Experience applying ML to anomaly detection, behavioral analytics, or security NLP.
  • Background in healthcare, financial services, or other regulated industries.
  • Enterprise vulnerability management experience — authenticated scanning, CVSS prioritization, automated reporting.
