Senior Site Reliability Engineer

Job Overview

We’re looking for a Senior Site Reliability Engineer who thrives at the crossroads of classic Linux and AWS infrastructure and modern Site Reliability Engineering. This is a high-impact, hybrid role designed for someone who can manage cloud resources, harden Kubernetes clusters, and shape a more reliable and developer-friendly platform.

We need you not just to maintain but to rethink and evolve our infrastructure, balancing hands-on operations with strategic improvements that future-proof our growing AI product landscape.

You’ll take over key responsibilities from our current Infra Lead who is transitioning to a software-focused role, giving you immediate ownership and space to shine.

Key Responsibilities

• Maintain and harden AWS infrastructure (EC2, ALB/NLB, WAF, IAM, CloudWatch)
• Operate and evolve our EKS clusters powering Python-based AI services
• Migrate existing services to Kubernetes using Terraform and Helm
• Codify infrastructure with Terraform and manage host-level automation via Ansible
• Build and improve CI/CD pipelines with GitHub Actions
• Own observability efforts: Prometheus, Grafana, alerting, and on-call readiness
• Support OS-level patching, certs, WAF rules, and general infra hygiene
• Partner with engineers to guide best practices and drive platform reliability
• Create clean, maintainable infrastructure documentation and playbooks
• Occasionally support rare off-hours incidents (don’t worry, really rare)

Required Qualifications

5+ years of experience managing Linux in production (Ubuntu, Amazon Linux)

Strong experience with Kubernetes (ideally EKS), Helm, and Terraform

Comfort with running and debugging Python workloads in containers

Solid understanding of networking, IAM, and cloud security best practices

Hands-on Nginx experience (Ingress and reverse proxy setups)

Excellent communication skills; you can explain complex infra to devs clearly

Nice to Have Skills

Strong Ansible skills beyond the basics

PostgreSQL or Amazon RDS tuning and operations experience

Deep understanding of observability tools (Prometheus, Grafana, Loki, etc.)

Familiarity with PHP production environments

Experience with TDD
