Threat and Incident Response Engineer

Volanno is seeking two Threat and Incident Response Engineers to support the information security team at Sound Transit the regional transit authority serving the Puget Sound area. The work spans the corporate IT network and the operational technology that runs transit systems. Time is split about evenly between responding to security incidents and proactive threat hunting with detection tuning running underneath both.

On the incident side this role owns alerts from the moment they arrive. That means triage out of SIEM EDR NDR and the OT monitoring platform then analysis escalation and guidance on containment eradication and recovery. This team member will write the root cause analyses and incident reports that go to Sound Transit leadership keep incident metrics current and build out response the OT environment the work also involves reading industrial network traffic and coordinating directly with plant and engineering staff since a response step that is routine on a corporate network can take something offline that needs to stay running.

On the hunting side this team member will form hypotheses and test them against endpoint network log and OT protocol telemetry. What the hunts turn up becomes new detection content. Coverage is mapped against MITRE ATT&CK to guide where hunts focus next and threat intelligence feeds back into the following round.

Alert quality runs through both halves of the job. Detection tuning is a standing part of the role so expect meaningful time on rule tuning suppression logic correlation and enrichment and SOAR automation.

This position will function within a highly motivated dynamic team. We are looking for someone who works calmly during an active incident and who takes the initiative on hunting rather than waiting for work to be assigned.

Required Background

Bachelors degree from an accredited U.S. college or university in Computer Science Information Security Information Systems or a related subject.

Minimum of ten (10) years of experience in cybersecurity operations for the senior position or five (5) or more years for the mid-level position covering both security incident response and proactive threat hunting.

Demonstrated experience responding to security incidents in an Operational Technology (OT) ICS or SCADA environment not enterprise IT alone.

Ability to pass a Sound Transit background check.

Ability to work Pacific Time business hours and to be onsite in the Seattle area on occasion.

Required Abilities Knowledge & Skills

Proven experience managing security incidents end to end from triage through containment eradication recovery and post-incident review.

Working proficiency with a major SIEM such as Microsoft Sentinel Splunk or QRadar including writing and tuning detection content.

Working proficiency with EDR such as Microsoft Defender for Endpoint CrowdStrike or SentinelOne and with network detection and response tooling.

Experience with OT monitoring platforms such as Dragos Claroty or Nozomi Networks.

Practical fluency with MITRE ATT&CK including ATT&CK for ICS and the ability to map detection and hunt coverage against it.

Ability to design and run hypothesis-driven threat hunts across endpoint network log and OT protocol telemetry.

Detection engineering skills including writing and refining correlation rules queries and use cases in SIEM and EDR platforms.

A track record of reducing false positives alert noise and duplicate ticketing with metrics to support it.

Familiarity with industrial protocols and industrial network traffic analysis such as Modbus DNP3 OPC or BACnet.

Experience folding threat intelligence into hunting and detection workflows.

Ability to produce incident documentation root cause analysis reports SOPs playbooks and metrics such as MTTD MTTR and SLA adherence.

Judgment to recognize when a standard IT containment action is unsafe in an operational environment and to work out a safe alternative with engineering staff.

Strong written and verbal communication skills with the ability to brief technical responders and executive stakeholders.

Ability to work independently within a client environment and coordinate across information security infrastructure operations and engineering teams.
