LastPass is looking for an Incident Responder: 

In this senior role, you will lead investigations end-to-end and advance our detection capabilities. You will own MSSP escalations, conduct threat hunts, and apply AI-assisted approaches — helping LastPass deliver on its mission to give everyone seamless access to everything they need to work, move fast, and stay protected.

About the team:

Our Security Intelligence & Response team operates at the front line of defending our cloud environments, customers, and platform. We are a collaborative, high-trust team where responders work closely across incident response, detection engineering, and threat intelligence — sharing findings, sharpening capabilities, and holding each other to a high standard in a fast-moving operational environment.

If you are passionate about complex problem solving and motivated by scale, then this is the role for you!

Who will you work with?

You will partner closely with the Detection Engineering team to build and tune analytics in Microsoft Sentinel, and collaborate with the broader Security Intelligence & Response team on threat hunts and investigations. You will also work with our Managed Security Service Provider, engaging their analysts to manage escalations and close gaps in coverage.

What are some of the exciting challenges you will be working on?

Own security incidents end-to-end — receive and validate MSSP escalations, lead investigations, coordinate response, and drive containment, eradication, and recovery

Conduct proactive threat hunts across cloud and endpoint telemetry, turning findings into durable detections that improve coverage and fidelity.

Build and tune detection content in Microsoft Sentinel and across the cloud security stack in close partnership with the Detection Engineering team

Develop and improve enrichment and response workflows to reduce manual effort, accelerate response times, and scale the team's impact

Apply AI-assisted approaches to triage, investigation, detection authoring, and automation — helping the team adopt these capabilities responsibly and effectively

Analyze logs and telemetry from cloud platforms, identity systems, endpoints, and network sources to detect and reconstruct attacker activity

Document investigations thoroughly — capturing actions, evidence, timelines, and conclusions — to a standard that supports both technical follow-up and stakeholder communication

Manage and strengthen the MSSP relationship by providing feedback on escalation quality, tuning alerting thresholds, and contributing to lessons-learned reviews

What does it take to work at LastPass?

Proven experience in incident response and security operations in cloud-native environments, with hands-on depth in Azure and AWS

Proven experience with Microsoft Sentinel or a comparable SIEM for investigation and detection engineering, including authoring and tuning detection content

Proven experience working with an MSSP — managing escalations, providing quality feedback, and closing gaps in coverage — whether as client or vendor

Proven experience conducting threat hunts and building automation in support of security operations, including SOAR playbooks, scripting, and enrichment workflows

Strong command of attacker tactics, techniques, and procedures, the cyber kill chain, and MITRE ATT&CK, with solid grounding in networking fundamentals, cloud security domains, and identity systems including Active Directory and Entra ID

Communicates clearly with both technical and non-technical stakeholders, exercises sound judgment under pressure, and operates effectively both independently and as part of a collaborative team

Commitment to continuous improvement — proactively contributing to detections, runbooks, tooling, and operational processes that raise the bar for the team

It's great, but not required :

Familiarity with the Intelligence-Driven Incident Response approach, integrating threat intelligence into the detection, analysis, and response lifecycle

Experience interpreting network traffic and performing packet captures using tools such as tcpdump or Wireshark

Background in relevant industry certifications such as GCIH, GCIA, GCFA, AZ-500, or AWS Security Specialty
