Security Automation Engineer
Stackline, Seattle, WA
The role
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.
