Security Engineer Job at Strata Decision Technology in Chicago

How you'll make an impact

We're looking for a hands‑on Security Engineer to help protect Strata's systems, data, and users. In this individual‑contributor role, you'll monitor and triage alerts, investigate and respond to incidents, tune and operate security tooling, and drive continuous improvements through detection, hardening, and automation. You'll collaborate closely with IT, Cloud/DevOps, and GRC teams to reduce risk and strengthen Strata's overall security posture.

Responsibilities

• Operate and tune SIEM to improve signal quality (detections, correlation rules, dashboards, data health).
• Maintain log source onboarding and coverage across endpoints, network, identity, and cloud.
• Perform hypothesis‑driven threat hunting using MITRE ATT&CK and available telemetry.
• Develop detections and enrichment pipelines; document runbooks and response playbooks.
• Monitor, tune and explain CSPM to stakeholders.
• Monitor and tune Antivirus tooling.
• Triage alerts, scope incidents, and execute containment, eradication, and recovery activities.
• Perform host, network, and cloud investigations; collect and preserve evidence.
• Produce clear incident reports and post‑incident reviews; implement corrective actions to prevent recurrence.
• Participate in an on‑call rotation for high‑priority security events.
• Run and tune vulnerability scans; validate findings and track remediation through closure.
• Prioritize using risk‑based approaches (e.g., exploitability, criticality, exposure).
• Provide actionable remediation guidance to system owners and verify fixes.
• Deploy, maintain, and optimize security controls (EDR, IDS/IPS, email security, WAF, DLP, CASB, secrets management).
• Build lightweight automations and integrations (SOAR, Python/PowerShell, APIs) to reduce MTTD/MTTR.
• Contribute to hardening baselines (CIS, NIST) and secure configuration across operating systems, identity, and network.
• Monitor and investigate security events across AWS/Azure/GCP (CloudTrail/Activity Logs, workload telemetry).
• Support guardrails and policy as code, assist with IaC scanning, secrets hygiene, and CI/CD security where applicable.
• Help maintain documentation, asset inventories, and control evidence for audits (SOC 2, HIPAA, PCI‑DSS, ISO 27001).
• Track and report security operations metrics (coverage, detection efficacy, MTTD/MTTR).
• Partner with IT, Cloud/DevOps, Compliance, Legal, and business teams to remediate findings and implement controls.
• Create clear user‑facing guidance and knowledge base articles; contribute to tabletop exercises and training.

Qualifications

• 2–5+ years of experience in security operations, incident response, or blue team roles.
• Hands‑on experience with SIEM (e.g., Splunk, Rapid7), EDR (e.g., CrowdStrike, SentinelOne, Carbon Black), and vulnerability management (e.g., Tenable, Qualys).
• Working knowledge of Windows, Linux, and macOS internals; common network protocols; identity systems (Okta/AD/Azure AD); and email security.
• Experience monitoring and investigating security events in public cloud (AWS, Azure, or GCP).
• Familiarity with frameworks and models such as NIST CSF, CIS Controls, and MITRE ATT&CK.
• Scripting ability in Python or PowerShell; version control familiarity (Git).
• Strong analytical, documentation, and cross‑team communication skills.
• Experience with SOAR platforms, SIEM content engineering, threat intel enrichment.
• Exposure to forensics tooling and packet analysis.
• Experience supporting audits and evidence collection for SOC 2, HIPAA, PCI‑DSS, or ISO 27001.
• Certifications such as GSEC, GCIA, GCED, GCIH, GCFA/GCFE, OSCP, CEH, or equivalent.
