Software Engineer 2, Platform

About the role

This is a hybrid role requiring 3 days a week. You must be work authorized in the United States without the need for employer sponsorship.

Responsibilities

• The Systems You Work On:
  • Observability & monitoring — Prometheus, Alertmanager, Grafana, and OpenTelemetry across production regions.
    • Add and tune metrics, dashboards, and alert rules, and learn how Prometheus and Alertmanager actually behave at scale - cardinality, recording rules, and alert routing.
  • Kubernetes & cloud infrastructure — multi-region EKS clusters: routine maintenance, node group changes, controller upgrades, and add-on configuration, with senior engineers alongside.
    • You'll help keep prod networking healthy and learn the multi-region topology.
  • AWS networking — VPCs, subnets and CIDR management, security groups, and Route53.
    • You'll help keep prod networking healthy and learn the multi-region topology.
  • CI/CD & artifact management — GitLab CI/CD pipelines, GitOps delivery through ArgoCD, and the Nexus artifact repository.
    • You'll help fulfill and then automate recurring requests (ingress, DNS, service accounts, IAM roles).
  • Access & identity — IAM roles and service accounts for apps in the clusters, Vault-managed secrets, and fulfilling access requests - then helping turn the repetitive ones into self-service.
    • You'll help investigate platform incidents and document what you learn.
  • Cost observability — OpenCost and cleanup work (e.g. orphaned EBS volumes) so cost is attributable rather than shared overhead.
    • You'll help keep prod networking healthy and learn the multi-region topology.

Qualifications

• 1-2 years of experience in software or infrastructure engineering.
• Bachelor's degree or equivalent experience.
• Comfortable in the terminal and reading YAML, Terraform, or similar declarative config.
• Some exposure to cloud (AWS or equivalent) and containers - production Kubernetes experience is a plus, not a requirement.
• Genuine interest in operating real systems - especially observability - and growing deep in them.
• Willing to learn how systems fail and to ask questions when something looks off.
• Effective communication; enjoys pair programming and code review.

Nice to have

• Hands-on exposure to Kubernetes, Terraform, or GitLab/GitHub CI/CD.
• Any experience with Prometheus/Grafana or another metrics stack.
• Scripting in Python, Bash, or Go.
