Security Automation Engineer

The Security Automation Engineer is a hands-on role responsible for Stackline's security posture, compliance program, and identity and endpoint platform. This covers a single Entra ID tenant, around a dozen federated applications, roughly 265 managed endpoints across macOS and Windows, and a SOC 2 Type II program tracked in Vanta with an external auditor.

For years, one generalist administrator ran this role — workable, but it revealed a limit: most of the week went to procedural work, running checklists and reconciling systems that disagree. That work has to be right but not done by hand. It needs a human to design it, and then to watch it run.

This role replaces that model with an engineer who automates the procedural half — evidence collection, offboarding, monitoring, and reconciliation — using scripts, services, and LLM agents. It builds on an existing internal repository of PowerShell and Python tooling, freeing capacity for the work that requires judgment: closing security gaps, hardening endpoints, driving vulnerability remediation, and carrying the compliance program.

The role splits roughly 40% security and compliance, 35% building automation, and 25% hands-on platform and deskside support. To support this on-site component, this position is based at our Seattle office 4 days per week.

Security Posture and Compliance

• →Own the majority of Stackline's ~50 SOC 2 Type II controls in Vanta; route the rest to owners in Engineering, HR, Finance, and Legal.
• →Drive vulnerability remediation to SLA — critical in 15 days, high in 30, medium in 90 — across endpoint findings.
• →Run quarterly access reviews, the annual risk assessment, policy and vendor reassessment, and the leadership security council.
• →Coordinate the annual penetration test and track findings to closure.
• →Own incident response for identity and endpoint compromise: investigate, contain, document.

Automation and Agents

This is the part of the job that makes the rest of it possible. You will identify the operational work that repeats and replace it with software that runs unattended and tells someone when it fails.

• →Extend the nightly evidence-collection pipeline into a maintainable, company-owned system.
• →Automate employee offboarding to match the orchestration already in place for onboarding.
• →Build certificate and secret expiry monitoring across federated applications and app registrations.
• →Reconcile assets between the endpoint management platform and the ITSM system of record.
• →Automate ticket triage, first-response drafting, and knowledge retrieval against IT documentation.
• →Build with production rigor: scoped service identities, idempotent runs, structured logs, real failure alerts.

Identity and Endpoint Platform

• →Administer Microsoft Entra ID: conditional access, authentication methods, groups and role assignment, SAML/SCIM integrations, app registrations.
• →Administer Microsoft Intune across macOS and Windows: compliance policies, configuration profiles, application packaging and deployment, enrollment, Apple Business Manager.
• →Close endpoint-hardening gaps: EDR on macOS, local administrator privilege management, centralized endpoint logging.
• →Federate standalone-authenticating applications so disabling one account revokes everything.

• You write real code. Production-quality Python or PowerShell, and the ability to read the other — not glue scripts you'd be embarrassed to hand over.
• Deep, hands-on identity experience. Entra ID or Azure AD at depth: conditional access, authentication methods, SAML/SCIM integrations, Graph API. Okta or Google Workspace depth works if you're ready to go deep on Entra quickly.
• Endpoint management at fleet scale. Intune or Jamf — configuration profiles, compliance policy, application packaging, enrollment, and what happens when a device falls out of compliance.
• You've carried a compliance framework, not just survived one. SOC 2, ISO 27001, or similar, from the inside — you know the difference between a control that's documented and one that's operating.
• You've built automation other people depended on. Scheduled jobs, API integrations, least-privilege service identities, and alerting for when it breaks at 3am.
• You're comfortable being the whole function. No tier one beneath you, no second administrator beside you. You decide, document, and say plainly when something is above your line.
• You'll be in the Seattle office 4 days per week. Parts of this job are physical and can't be done remotely.
• Bachelor's degree in information technology, computer science, cybersecurity, or a related technical field, or an equivalent combination of education, certifications, and relevant professional experience.

• Shipped something real with LLM agents and tool use — Claude Code, MCP servers, or an agent framework — and can talk about what broke in production, not just what demoed well.
• macOS security depth: endpoint detection, privilege management, unified logging.
• Networking you've configured yourself: VLANs, dual-WAN failover, Meraki or UniFi.
• Automated against an ITSM platform's API and hit the credential-scope wall everyone hits.
• Incident investigation: sign-in forensics, audit log analysis, mailbox rule and OAuth grant abuse.
