- Develop and maintain integrations across the security stack (SIEM, EDR, threat intelligence, case management, ITSM) using REST APIs, webhooks, and event-driven patterns
- Build internal tools, services, and APIs, primarily in Python, that extend platform capability and reduce analyst toil
- Administer and improve the case management platform and its workflows
- Partner with detection engineering to operationalize new detections into automated response
- Contribute to shared engineering standards: Git-based workflows, code review, testing, and CI/CD
- Measure what you build: automation throughput, MTTR, false-positive burden, and analyst time saved
- Write clear documentation and runbooks; collaborate effectively across a global, distributed team

- Hands-on experience with SOAR or security automation platforms
- (Splunk SOAR, XSOAR, Tines, Torq, or similar)
- Experience building with modern LLM platforms (Anthropic Claude,
- OpenAI, Amazon Bedrock, or similar): using APIs, SDKs, and tool-use patterns to build tools, integrations, and agents, with practical prompt and agent design and evaluation of model output for reliability and safety
- Software engineering fundamentals: Git, code review, automated testing, CI/CD
- Working knowledge of SOC operations and incident response workflows; familiarity with MITRE ATT&CK
- Strong documentation habits and written communication; effective in a distributed global team
Wed Love to See:

- Splunk Enterprise Security exposure (SPL, detection logic) or detec-
- tion-as-code experience
- Case management or ITSM platform experience (ServiceNow or
