About the Role We're hiring the first Security Automation Engineer for Sunbit's new Security Operations (SecOps) team, reporting directly to the SecOps Team Lead. SecOps is the single point of accountability for security operations at Sunbit. We run the pipelines that take an alert or finding from detection to verified closure, working with Engineering, IT, GRC, and application teams. We cover a broad security domain with a deliberately lean team, and that only works if the pipelines run themselves. Your job is to build that. You'll build the workflows and integrations that connect our security tools to each other, to Jira, and to Slack, so alerts arrive enriched, findings reach the right owner with context, and follow-up happens without anyone chasing it by hand. This is a hands-on engineering role: you'll build workflows and write code every week, and we expect you to use AI tools to move faster. We care more about what you've built than about years of experience. What You'll Do Security Automation & Integrations • Build and maintain automation workflows that connect our SIEM, EDR, cloud detection, vulnerability, and SaaS/data security tools via REST APIs and webhooks • Build scan-to-ticket pipelines, alert enrichment, and remediation routing that send each finding to the right team with full context • Add AI-assisted steps where they help, such as LLM-based alert summaries and context gathering, with a human in the loop where it matters • Automate SLA reminders, escalations, and status reporting so follow-up runs on its own • Keep automations and AI agents secure: least-privilege API access, secrets handling, and prompt-injection risk Detection & Response Operations • Triage security alerts across cloud, endpoint, and identity; classify them per our severity framework and escalate confirmed incidents • Turn every repeated triage step into an enrichment or auto-resolution playbook • Track false-positive rates and work with Engineering on detection tuning • Document incidents, maintain timelines, and keep runbooks and playbooks current Compliance Automation & Metrics • Automate recurring evidence collection for SOC 2 and PCI DSS • Build dashboards for time to respond, SLA compliance, false-positive rates, and automation coverage Requirements • Hands-on experience in security operations, IT, DevOps, or software engineering, or equivalent hands-on security projects (internship, labs, home lab, CTFs) • Security fundamentals: common threats, attack techniques, and controls, plus some hands-on alert triage or log investigation • Scripting ability: you can build a script that calls a REST API and handles authentication and errors, and you can read, test, and debug it • You've built at least one automation or integration for a security or operational workflow, with n8n, Tines, a SOAR, or your own scripts • You use AI coding tools and LLMs day to day • Basic understanding of cloud environments (AWS, GCP) • Comfortable with Jira (or similar) and clear written English for tickets, runbooks, and follow-ups Nice to Have • Workflow automation or SOAR platforms (n8n, Tines, Torq, Cortex XSOAR, Splunk SOAR) • Hands-on with SIEM, EDR, cloud security, or vulnerability tools, through their APIs and not just their consoles • Built LLM-powered workflows or AI agents (LLM APIs, MCP, AI nodes in n8n) • Interest in AI security: prompt injection, agent permissions, data leakage through LLMs • Git, Terraform, CI/CD, or detection-as-code (e.g., Sigma rules) • Building dashboards on operational or security data • Compliance automation in a regulated environment (SOC 2, PCI DSS) • Fintech experience • A GitHub repo or portfolio of things you've built Why This Role Is Different • Hire #1 on a new team, with real influence on how SecOps is built at Sunbit • Broad scope on a modern stack: detection and response, cloud security, vulnerability management, identity, data security, and compliance • Automation-first: your success is measured by how much manual work you eliminate, and you'll have real room to apply AI to security operations • Direct mentorship from the SecOps Team Lead, with a clear growth path as the team scales Recruitment Fraud Disclaimer We’ve been made aware of fraudsters impersonating Sunbit employees during the hiring process.
