About this role
The Corporate Security Threat and Response Management product ownership team at Mastercard is looking for a Lead Level Security Engineer to help drive our Security Operations modernization strategy. The RESPOND product team executes on the multi-year strategy and roadmap to evolve and modernize SecOps incident investigation and response technology, capabilities, tools, and process.
Responsibilities
- Execute the RESPOND product roadmap in close partnership with SOC and Incident Response teams in the region.
- Design, build, test, and maintain SOAR playbooks used for incident triage and response scopes to collect and process digital evidence and artifacts at speed and scale.
- Build and operationalize AI-augmented response capabilities, including agentic AI workflows integrated into triage, enrichment, and response, prompt books and prompt libraries tuned for SOC and Incident Response use cases, prompt-book/code notebook development for repeatable investigation, hunt, and DFIR workflows, and LLM-driven enrichment and summarization integrated into case management.
- Define strategic requirements and oversee management for connectors, apps, and integrations between SOAR, SIEM, EDR, identity, ticketing, threat intelligence, and AI/LLM platforms for build through our dedicated engineering partners.
- Build and maintain response tooling such as scripts, live-response packages, enrichment services, and automation utilities deployable via EDR and SOAR.
- Embed with SOC and DFIR analysts to identify high-toil workflows and convert them into automated, AI-assisted, or fully autonomous playbooks with appropriate guardrails.
- Tune and optimize playbooks and AI-assisted workflows against measurable outcomes including MTTR, false-positive rate, analyst touch time, and AI-assist accuracy.
- Contribute to centralized response tooling, prompt book, and notebook libraries, ensuring code quality, documentation, version control, and reusability across regions.
- Support major incident response activities by deploying and operating response tooling and AI-assisted investigation workflows under pressure.
- Provide feedback into the product backlog and partner with the PO on requirements refinement, and document playbooks, prompt books, notebooks, and technical designs to enterprise standards.
Required qualifications
- 5+ years in security operations, incident response, detection engineering, or security automation engineering.
- Hands-on SOAR development experience with low-code/no-code or hyper-automation tools and concepts.
- Demonstrated enterprise experience executing on AI-augmented SOC concepts, including building and maintaining AI prompt books for analyst workflows, developing Jupyter notebooks for investigation, hunt, or DFIR, integrating LLMs or agentic AI into XDR, SOAR, case management, or response tooling, leveraging IDEs with AI connectors to process data and execute AI workflows, or deploying agent-based AI workflows for triage or enrichment in production.
- Strong scripting skills in Python and PowerShell, and comfortable with basic code repo management using Git or equivalent.
- Working knowledge of REST APIs, JSON, webhooks, and authentication patterns including OAuth, API keys, and managed identities.
- Solid grounding in incident response fundamentals and the IR lifecycle.
- Hands-on experience with EDR platforms, SIEM, identity platforms, cloud platforms, and cloud protection products.
- Familiarity with MITRE ATT&CK and the ability to map response actions to adversary techniques.
- Demonstrated ability to operate inside an agile delivery model with a product backlog.
Preferred qualifications
- Bachelor’s degree in computer science, cybersecurity, or IT-focused disciplines (or equivalent experience).
- At least two Industry certifications such as GCFA, GCIH, GNFA, GCFR, GREM, or equivalent.
- Experience with SecOps focused MCP server architectures, agentic frameworks, or tools.
- Experience building EDR live-response scripts and tool libraries.
- Exposure to detection-as-code and response-as-code practices, including CI/CD for security content.
- Background in regulated financial services or Fortune 500 SOC environments.
