We re looking for a Senior Site Reliability Engineer SRE who is responsible for designing operating and scaling our self hosted bare metal infrastructure production Kubernetes clusters data platforms and security architecture within a restricted network environment
This role requires a software minded systems engineer who treats operations as a software engineering problem owning systems end to end establishing meaningful SLOs automating away toil with production grade Python Go tooling and bringing deep expertise across infrastructure data platforms or security
Key Responsibilities
Bare Metal Platform Offline Operations Design operate and scale Kubernetes clusters Linux servers networking and storage on bare metal own high availability HA disaster recovery DR capacity planning and air gapped workflows internal registries mirrors offline certificates while migrating legacy services to declarative GitOps Argo CD Helm Pulumi Terraform
Reliability Engineering Incident Leadership Establish SLOs and error budgets refine observability stacks Prometheus VictoriaMetrics Grafana Sentry lead critical incident response conduct blameless postmortems and ensure systemic fixes are implemented
Internal Tooling Self Service Automation Develop internal developer platforms and automation services in Python or Go with full code review testing and software engineering rigor
Data Infrastructure Resiliency Operate and maintain core data stores and pipelines including PostgreSQL ClickHouse Redis Elasticsearch and Airflow ensuring reliable backups replication Point in Time Recovery PITR and tested restore capabilities
Infrastructure Security IAM Own SSO identity systems Authentik secrets management Vault External Secrets server hardening audit logging and continuous vulnerability remediation
Technical Leadership Documentation Make foundational architectural decisions conduct design reviews mentor engineers and maintain clean documentation structured for both human teams and AI agents
AI Augmented Operations Leverage AI assistants daily and design scoped validated agentic workflows with human in the loop safeguards for sensitive operational actions while exercising judgment on when deterministic automation is superior
Qualifications Requirements
Deep understanding of Linux internals performance tuning and low level system debugging
Strong networking fundamentals across TCP IP DNS TLS load balancing and reverse proxies Traefik HAProxy
Hands on experience running production Kubernetes networking storage scheduling RBAC operators Helm
Strong programming skills in Python or Go capable of shipping tested maintainable production tooling rather than ad hoc scripts
Solid operational experience with PostgreSQL replication backup strategies PITR and query performance
Proven track record operating distributed systems with a clear mental model of failure modes observability design and actionable alerting
Practical command of infrastructure security IAM secrets management CI CD pipelines Infrastructure as Code IaC and GitOps workflows
Deep Specialization in at least one domain
Infrastructure Bare metal Kubernetes IaC GitOps and HA DR architecture
Data PostgreSQL ClickHouse Airflow ETL ELT and high throughput event pipelines
Security IAM SSO secrets engines system hardening threat modeling and incident response
Preferred Qualifications Nice to Have
Experience operating infrastructure in restricted or air gapped environments
Hands on experience with multi cluster Kubernetes cross site Disaster Recovery or CNI CSI eBPF internals
Experience operating and upgrading ClickHouse Kafka Elasticsearch or self hosted developer tools e g GitLab Sentry
Open source contributions or practical experience deploying production AI agents in engineering workflows
What Makes This Role Unique
At Zarrino we self host nearly our entire stack on bare metal giving you complete ownership from physical hardware and network edge up through Kubernetes data warehouses and internal developer platforms This is a pure engineering role rather than traditional ticket based operations seniority is measured by autonomy architectural clarity and systemic impact rather than years of experience or tool checklists
