- Design and oversee AI-assisted load testing, stress testing, and capacity planning workflows.
- Guide the migration from monolithic deployments to multi-tenant Kubernetes platforms.
- Reduce infrastructure spend through architectural decisions, right-sizing, and intelligent scaling strategies.
- Build and supervise automation for infrastructure provisioning, configuration management, and observability.
- Set clear operational standards for reliability, performance, and incident response—and raise the bar for how we run production.
What You Bring:
- 7+ years operating and evolving large-scale production systems.
Deep Linux systems expertise with hands-on performance tuning across CPU, memory, disk, and networking.
- Strong Python skills for automation, tooling, and AI-assisted systems workflows.
- Production experience with Ruby/Rails ecosystems, including Puma and Sidekiq.
- Proven ability to diagnose and resolve complex database performance issues (MySQL/MariaDB or PostgreSQL).
- Advanced Kubernetes experience—workload sizing, scheduling, and multi-tenant operations.
- Infrastructure-as-code mastery using Terraform and Terragrunt.
- Experience with configuration management tools such as Puppet or Ansible.
- Strong observability instincts across metrics, logs, and traces using tools like Prometheus, Grafana, Datadog, or ELK.
- AI fluency—comfortable supervising AI agents for analysis, testing, and reporting, and validating their outputs.
- A builder mindset. You move fast, take ownership, and raise standards.
Preferred Background:
- Scaling and refactoring monolithic applications under real production load
- Extracting databases or stateful components from monoliths
- Apache and Nginx tuning at scale
- Redis performance optimization and operational management
- CI/CD systems and GitOps workflows, including ArgoCD
