Full description
MissionOne Media is a brand within BarkleyOKRP that combines full-funnel media planning and buying services, CRM, data, analytics, retail media, SEO, and digital experiences. We're an independent media partner offering transparency, integration, and a relentless focus on business impact.
We're looking for a Senior Infrastructure Engineer to act as the operational backbone of our engineering team. The initial focus of this role is to take operational ownership of our legacy environment, while helping shape the architecture and strategy for our future-facing projects.
You'll ensure the stability, security, and high availability of our core production VMs running Java/Tomcat applications and MySQL 5.7 instances. You'll manage incidents, diagnose root causes, tune performance, and keep these critical legacy systems stable.
At the same time, you'll partner with us on our long-term growth. We're actively developing multiple new products and services on modern tech stacks and need someone who can balance maintaining legacy reliability with helping us design and scale our next-generation cloud architecture.
Responsibilities:
-
Incident Response & Operational Stability: Own the incident management lifecycle for production. Triage alerts, troubleshoot OS-level bottlenecks, debug performance issues, and drive rapid root-cause analysis.
-
Performance Monitoring & Debugging: Actively monitor system performance, application logs, and resource health using modern observability platforms (such as Observe by Snowflake) to quickly diagnose and resolve operational issues.
-
Legacy Infrastructure Management: Proactively maintain, patch, and secure our existing virtual machines on GCP.
-
Legacy Database Operations & Health: Monitor MySQL 5.7 instances, manage backups, and troubleshoot connection pool exhaustion or locking issues.
-
Cloud Architecture & Modernization: Collaborate to design, provision, and scale forward-looking cloud infrastructure for our new products and services, incorporating modern cloud-native tools and managed services (such as Cloud SQL and BigQuery).
-
Automation & Infrastructure-as-Code (IaC): Gradually replace manual operational tasks with clean automation scripts and infrastructure tools to reduce toil and improve repeatability.
-
Security & Compliance: Ensure systems comply with enterprise security baselines through rigorous OS hardening, access controls, and vulnerability patching.
Qualificiations:
-
Experience: 5+ years in a System Administration, Site Reliability Engineering (SRE), or Infrastructure Operations role within an enterprise environment.
