Senior Platform Engineer, Foundations

The engineering team at Chainalysis is inspired by solving the hardest technical challenges and building products that establish trust in cryptocurrencies. We are a global organization that thrives on challenging work and doing it alongside exceptionally talented teammates. Our industry evolves rapidly, and our mission is to build a flexible, AI-driven platform that helps organizations investigate illicit activity, manage risk exposure, and participate in the cryptocurrency ecosystem with confidence. 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. As a Senior Platform Engineer, you will design, build, and operate the foundational services that enable Chainalysis engineers to deliver and run software safely. You will own complex technical work from inception through production, influence platform standards and roadmaps, and help create systems that are highly available, observable, secure, and easy for other engineers to use. In this role, you’ll: 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 We’re looking for candidates who have: 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
