Join a stellar team of leaders and experts in blockchain technology, cryptography, and security. We are building the backbone of blockchain wallet infrastructure for the next financial era. We are seeking a Senior Infrastructure Engineer to design, operate, and scale systems at the intersection of blockchain, cybersecurity, and distributed infrastructure, preparing us to meet the demands of a trillion-dollar industry.

This role goes beyond maintenance—you will be an architect, automator, and security expert. You will embed best-in-class DevOps and SRE practices into our workflows, ensuring our services are highly reliable, secure, and cost-efficient. You will collaborate across engineering, product, and security to translate complex requirements into scalable infrastructure.

Key Responsibilities:

• Infrastructure Architecture: Design, build, and maintain cloud infrastructure with a core focus on scalability and security.
• 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).
