Job Title Threat Detection & Automation Engineer About your role: As a Threat Detection & Automation Engineer, you will enable end-to-end detection engineering across telemetry onboarding, detection content development, response automation, and threat reporting within Cyber Security Operations at Fiserv. You will partner with threat intelligence, threat hunting, incident response, red team, platform, and engineering teams to build and operate resilient detection infrastructure and integrations at enterprise scale. Your work will improve detection fidelity, strengthen operational awareness, and support timely response to credible threats across the Fiserv environment.

Research adversarial techniques and translate threat behaviors into high-fidelity detections aligned to complex cybersecurity use cases. Design, build, and operate production-grade security detection infrastructure across Google SecOps and internal automation applications that support enrichment, orchestration, and response workflows. Lead telemetry and detection lifecycles, including source onboarding, parsing, normalization, enrichment, testing, deployment, tuning, and ongoing maintenance. Develop custom integrations, automations, and lightweight services using application programming interfaces (APIs), webhooks, and event-driven patterns to improve signal fidelity and reduce mean time to detect and mean time to respond. Create dashboards, metrics, and reports using business intelligence tools, structured query language (SQL), statistical analysis, and applied artificial intelligence and machine learning techniques to improve threat visibility and operational reporting. Apply Python, prompt-driven workflows, model context protocol (MCP) capabilities, and agent-to-agent orchestration patterns to support detection engineering, enrichment, and analytic decision support. Collaborate with threat intelligence, threat hunters, incident responders, red team, and engineering partners to evaluate detection coverage gaps and improve defensive capabilities. Manage work through Agile practices, documenting requirements, tracking delivery, and maintaining reliable platform operations across hybrid environments. Responsibilities listed are not intended to be all-inclusive and may be modified as necessary. Experience you'll need to have: 8+ years of experience in cybersecurity engineering, security operations, or detection engineering, including building and maintaining detections for enterprise security environments. 8+ years of experience developing and tuning detections using security information and event management (SIEM) technologies, security orchestration, automation, and response (SOAR) platforms, and correlated rule logic for complex threat scenarios. 8+ years of experience scripting and automation development using Python, SQL, PowerShell, Bash, or similar languages to support integrations, telemetry processing, and response workflows. 8+ years of experience working with cybersecurity technologies such as endpoint detection and response (EDR), intrusion detection systems or network detection and response (IDS/NDR), user and entity behavior analytics (UEBA), data loss prevention (DLP), web application firewall (WAF), proxy technologies, and cloud security services. 8+ years of experience designing and supporting application programming interface (API) integrations using representational state transfer (REST), JavaScript Object
