Our mission is to build trust in blockchains, blending safety and security with an unwavering commitment to growth and innovation.

🎯 The Role

Platform Engineering provides the shared infrastructure, tooling, and developer experience layer that powers every engineering team at Chainalysis. The team is evolving toward consolidated, scalable platform patterns that support global growth, improve reliability, and reduce the operational burden on product engineers. We partner closely with Developer Productivity, Information Security, Cost Optimization, and R&D teams to provide secure, self-service paths from development through production.

✅ Key Responsibilities

• Design, operate, and continuously improve highly available platform services, including managed Kubernetes clusters, Kafka, CI/CD systems, artifact management, and related shared infrastructure
• Build secure, scalable infrastructure across AWS and other cloud environments using infrastructure as code and repeatable automation
• Improve production reliability through well-defined SLOs, graceful degradation, self-healing, automated recovery, and effective incident response
• Create self-service workflows and platform abstractions that reduce cognitive load and help R&D teams ship and operate software more effectively
• Partner with Information Security, Cost Optimization, and engineering teams to strengthen controls, improve cloud efficiency, influence technical direction, and contribute to the platform roadmap

📌 Required Qualifications

• Deep experience designing, operating, and troubleshooting production infrastructure in AWS, including services such as IAM, EC2, EKS, RDS, MSK, S3, Lambda, VPC, and networking
• Experience administering and scaling multi-tenant Kubernetes clusters and streaming platforms such as Kafka in production, including upgrades, workload isolation, reliability, security, and incident response
• Experience building and maintaining infrastructure as code, pipeline-as-code, containerization, and cloud-native systems using tools such as Terraform, Helm, Ansible, Jenkins, GitHub Actions, Docker, or Kubernetes
• Experience designing observability for production systems and tuning relational databases, ideally PostgreSQL, using tools such as Datadog or Prometheus
• Strong software-engineering or scripting skills in one or more languages such as Python, Go, Java, Scala, or shell, plus a track record of owning ambiguous cross-functional problems and communicating tradeoffs clearly

⭐ Desirable Experience

• Experience with elevating developer productivity and the developer experience
• Experience building self-service tooling or reusable platform abstractions for engineering teams
• Interest in cryptocurrencies and blockchain technology, or curiosity and willingness to learn
• Experience operating in a security standards-compliant environment such as ISO 27001, NIST 800-171, or SOC 2
