• Automation & SRE: Architect and operate containerized systems (Docker, Kubernetes), automating provisioning and deployments using Terraform, Jenkins, and CI/CD pipelines.
• Security & Resilience: Configure and manage secure enclaves (e.g., AWS Nitro) to harden critical workflows and improve overall system resilience.
• Observability: Implement and maintain robust observability with tools like Datadog across logs, metrics, and traces.
• Optimization: Optimize performance and reliability of Node.js applications and backend services.
• Strategy Alignment: Partner with product and security teams to align infrastructure decisions with the roadmap and risk strategy.

• Experience: 8+ years of infrastructure, DevOps, or SRE experience in cloud-native systems.
• Cloud Expertise: Strong expertise with AWS (Lambda, EKS, API Gateway, DynamoDB, S3, etc.). GCP is a plus.
• IaC & CI/CD: Highly skilled in Infrastructure-as-Code (Terraform) and advanced CI/CD automations.
• Containerization: Deep knowledge of Docker, Kubernetes, and containerized microservices architecture.
• Database Management: Experience administering and tuning SQL and NoSQL databases.
• Security: Solid understanding of infrastructure security and applied cryptography fundamentals.
• Programming: Proficiency in scripting and systems programming (Python, Go, Rust, or TypeScript).
• Soft Skills: Clear communication skills, ability to operate under pressure, and make sound technical decisions.

Preferred Experience (Nice-to-Haves):

• Experience with blockchain networks and smart contracts.
• Familiarity with other secure infrastructure providers (e.g., IBM, Thales).

• Salary: Highly competitive base salary range of $180K–$300K per year (full-time).
• Equity: Generous stock options (100–200) package vested over 4 years.
• Core Benefits: Comprehensive Healthcare, 401K, and coverage for travel expenses.
• Location: Remote-first role within the United States, with office options available.
• Equipment: Provided with a MacBook Pro and essentials for a high-performance setup.
