📋 About Phase Labs

Phase Labs is a premier Solana-native team deeply engaged with the Solana ecosystem. We're known for exceptional validator expertise, ecosystem contributions, and community-first mentality. We are a remote-first team spread across the Americas.

Phase Labs builds critical infrastructure across three flagship products:

• Netrunner (crypto tax software)
• Aero (Solana stake pool operations)
• Sentinel (institutional staking and validator operations platform)

🚀 Your Mission

1. 🛠 Product Infrastructure Ownership & SRE
   1. Design and build cloud environments for Netrunner, Aero, and Sentinel then operate them as an SRE (incident response, runbooks, post-mortems).
   2. Write scripts in Python, Bash, or Go to automate routine maintenance, scaling, and recovery tasks.
   3. Extend into tooling for validator and stake pool operations (monitoring hooks, data exporters, health checks)

2. ⚡ CI/CD Optimization & Developer Experience
   1. Continuously audit and refine pipelines to speed up build-test-deploy cycles.
   2. Introduce improvements like parallel builds, cache strategies, quality gates, canary and blue-green deployments.
   3. Partner with engineering leads to identify pain points and deliver tailored DevOps solutions.
3. 💻 Infrastructure as Code & Cloud Automation
   1. Define and maintain Terraform or Pulumi modules and CloudFormation templates.
   2. Enforce Git-driven IaC workflows with code reviews, versioned modules, and drift detection.
4. 🐳 Containerization & Orchestration
   1. Package microservices in Docker containers and manage them with Kubernetes (EKS, GKE, or AKS) or Docker Swarm.
   2. Develop Helm charts or operators for consistent, scalable deployments.
5. 🔍 Monitoring, Observability & Data Backbone
   1. Build and operate an observability stack with Grafana for products and the validator fleet.
   2. Define service level objectives (SLOs) and indicators (SLIs), set up alerts, and manage on-call rotations.
   3. Expose metrics, logs, and traces to support future validator data products.
6. 🔐 Security, Compliance & Cost Management
   1. Integrate security scans into pipelines and apply IAM, network, and secrets management best practices.
   2. Optimize cloud costs via rightsizing, autoscaling policies, and budget alerts.
   3. Support SOC2 and ISO audits for Sentinel.
7. 📝 Documentation & Collaboration
   1. Produce runbooks, architecture diagrams, and onboarding guides for each product and validator use case,
   2. Collaborate with product, engineering, and validator operations teams to roadmap infrastructure improvements.
