Responsibilities

Build Our Detection Platform: Lead SIEM evaluation and implementation, design log ingestion and routing pipelines, and make deliberate cost/retention trade-offs across hot search and long-term archive

Engineer High-Signal Detections: Develop and tune detection content across cloud, identity, endpoint, SaaS, and application telemetry — with an emphasis on business-logic detections built on our own products' audit events

Define the Telemetry Contract: Partner with Engineering and DevOps to specify what our applications and infrastructure must log — the audit events that make our most important risks detectable in the first place

Lead Incident Response: Build and maintain IR playbooks and runbooks, coordinate response during security events, run the annual tabletop exercise, and drive post-incident reviews that actually change things

Detect Data Exposure: Partner with internal teams to detect sensitive data moving where it shouldn't — including PHI — across applications, endpoints, and SaaS

Manage 24/7 Coverage: Define requirements for and direct our managed detection partners, own escalation procedures, and continuously raise the bar on what "monitored" means

Security OperationsDetection EngineeringIncident ResponseSecurity Information and Event Management (SIEM)PythonSQLCloud-Native TelemetrySecurity AutomationApplication InstrumentationManaged Detection and Response (MDR/MSSP)Required

5+ years in security operations, detection engineering, or incident response, including experience building (not just running) a detection and response capability at a startup or high-growth technology company

Hands-on experience implementing or significantly maturing a SIEM, including custom log sources and detection content — not just operating one that was handed to you

Strong detection engineering skills: writing detections in Python, SQL, or a rules DSL, managing them in version control, and measuring their quality

Real incident response experience — you've led investigations, written the playbooks, and run the retros

Experience with cloud-native telemetry (AWS/GCP/Azure control plane, identity providers, endpoint, SaaS audit logs)

Strong programming or automation skills (Python preferred); comfort building integrations and response automation

A builder mentality — you'd rather engineer the alert away than triage it forever

Preferred

Experience partnering directly with software engineers to instrument applications for security visibility is a strong plus

Familiarity with securing or monitoring AI/LLM-powered systems is a strong plus

Experience working with MDR/MSSP providers — and opinions about what they're good and bad at

Relevant security certifications (GIAC/GCIA/GCIH, CISSP, etc.) are a plus, but practical engineering experience matters more
