Our team treats AI as a core part of how we work. We build and use AI agents and automated workflows to handle toil, speed up investigation and response, and give our team more time for high-leverage work.
Who You Are
Our ideal candidate is a security engineer who likes to build. You are as comfortable writing a detection or a response playbook as you are working an incident. You think in systems: you see the gaps between tools and close them by wiring the tools together. You make sound security decisions on your own, explain them clearly to technical and non-technical people, and balance risk with how people actually work.
You stay calm when something breaks. You can take a vague report, work out quickly what happened and who is affected, and give leaders a clear, evidence-backed answer. Then you fix the root cause so it doesn't happen the same way twice.
You're curious about how AI is changing security operations, and you're eager to put it to work on triage, enrichment, and response.
Your Impact
As a Senior Security Operations Engineer on Fleetio's Business Technology team, you will:
Own detection engineering and threat hunting in CrowdStrike Next-Gen SIEM: onboard log sources, write and tune detections across identity, email, SaaS, and endpoint telemetry, and keep false positives down
Own security automation: chain our tools together through CrowdStrike Fusion SOAR and our workflow automation platform so a signal in one (a risky Okta sign-in, a Falcon detection, a Mimecast hit, a Google Workspace sharing change) triggers enrichment, containment, paging, and ticketing in the others, plus AI agents that speed up triage and investigation, so routine response runs without waiting on a human
Lead corporate incident response as technical lead, including third-party and supply-chain events: scope exposure quickly, confirm or rule out compromise, run forensics, tell leaders and employees what to do, keep runbooks current with Product Security, and serve in the escalation rotation, backing up the Incident Commander when needed
Own CrowdStrike Falcon configuration and detections, manage the Falcon Complete relationship and escalations, and maintain device trust checks and an inventory of software and extensions on company devices with clear guidance on approved tools
Own Okta authentication policy, MFA, session policy, and privileged access management, and automate user access reviews and audit evidence with Compliance so SOC 2 controls run with less manual effort
Own Mimecast policy, secure network access, Google Workspace and key SaaS security settings, and SaaS security posture in CrowdStrike Falcon Shield, driving findings to closure with app owners
Own data loss prevention: define and classify Fleetio's sensitive data, design and tune DLP policies across email (Mimecast), Google Workspace, endpoints (CrowdStrike), and key SaaS apps, and investigate and respond to data exposure, whether from accidental oversharing, a compromised account, or insider misuse
Own security for Fleetio's use of AI: visibility into AI tool usage, identity and access for AI agents, guardrails for internal agents and automations, and AI detection and response (CrowdStrike Falcon Guardian, formerly AIDR)
Run vulnerability management for corporate assets, prioritizing by exploitability and holding owners to fix deadlines, and report on security posture with clear, honest metrics that help set program priorities
Your Experience
5+ years of experience in security operations, detection and response, or security engineering, ideally at a SaaS company
Detection engineering and threat hunting in a SIEM (CrowdStrike Next-Gen SIEM or similar)
Security automation: building SOAR playbooks (CrowdStrike Fusion or similar) that connect identity, endpoint, email, and SaaS tools into a single response flow, with Python or PowerShell and REST APIs
Incident response from first triage through forensics, root cause, and follow-up across cloud, identity, and SaaS environments, including working with an MDR or managed SOC provider
Identity security with Okta or a similar provider: authentication policy, privileged access, and access reviews in a SOC 2 or ISO 27001 control environment
Endpoint security with CrowdStrike or similar, including macOS, plus device trust and endpoint query tooling
Email security (Mimecast or similar) and SaaS security posture management
Designing and running a DLP program: data classification, policy design and tuning across email, cloud collaboration, and endpoints, and investigating data exposure
Securing developer tooling and the software supply chain (IDE extensions, package registries, AI coding tools)
Excellent written and verbal communication skills, including explaining risk to non-technical leaders
Considered a Plus
Experience securing a company's use of AI: AI tool governance, identity and access for agents, data-exposure and prompt-injection risk, and AI detection and response tooling (CrowdStrike Falcon Guardian/AIDR or similar)
Experience building AI agents, LLM-powered automations, or integrations (e.g., using tool/function calling or MCP) for security operations workflows
Experience using LLMs on real security alerts for triage, enrichment, and investigation
