About the role

Key responsibilities & impact

End-to-end ownership of our cloud infrastructure on GCP, architecture, reliability, cost, scalability, and operational excellence
The full cloud-native application environment; containerized and serverless workloads, cloud networking, and the large-scale, multi-tenant data layer (many terabytes of customer data on MongoDB Atlas), including the architecture, performance, and scaling decisions across all of it
Deployment, release, and maintenance processes, with a focus on uptime and minimizing customer-facing disruption, recognizing that a platform outage during an active warehouse shift is a customer event, not just a ticket
Leadership of our senior SRE, providing direction and architectural vision to move the platform forward
Our overall security program, policy, posture, tooling, and incident response, across both businesses
Achieving and maintaining SOC 2 Type II (and evaluating ISO 27001 as the customer base demands), including driving the program, evidence, and audit relationships
Customer-facing security: questionnaires, audits, and trust conversations with security-conscious enterprise buyers
Data protection obligations as a data processor, including PII handling and relevant privacy regimes (e.g. GDPR, CCPA)
Managing security vendor relationships (MDR/EDR, SIEM, endpoint protection, penetration testing)
Oversight of the internal IT function, corporate network, on-prem and cloud infrastructure, identity, endpoint management, help desk, and vendor relationships
Light-touch oversight of a small, hosted WMS environment on GCP, including its reliability and availability commitments
Mentorship and development of an established IT team, including an IT Manager and IT Administrators who handle the day-to-day
