More about our team and company:

- Fleetio overview video:  Our careers page:  Business Technology team is looking for a Senior Security Operations Engineer to own the security of the tools, devices, identities, and data Fleetians rely on every day. You will help run corporate security operations end to end, covering detection and response, identity, endpoint, email, and SaaS security, data loss prevention, AI security, and vulnerability management, and make the day-to-day security calls that keep Fleetio safe.

You will be hands-on: engineering controls, writing and tuning detections, automating response, and closing gaps, not just administering tools. The goal is one connected defense, not a collection of consoles: a signal from Okta, Crowd Strike, Mimecast, or Google Workspace should drive action in the others automatically, so the environment protects itself and people step in only where judgment is needed.

Around-the-clock monitoring is handled by our external SOC (Crowd Strike Falcon Complete); this role engineers the environment it watches, owns what happens when it escalates, and extends what it can see. You will work closely with our IT Operations and Compliance teams, our 3rd party SOC, and the Product Security team in Platform Engineering.

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 Crowd Strike 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 Crowd Strike 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…
