Senior Platform Engineer, Foundations

About the role

The engineering team at Chainalysis is building an AI‑driven platform to help organizations investigate illicit activity and manage risk in the cryptocurrency ecosystem. As a Senior Platform Engineer you will design, build, and operate foundational services that enable engineers to deliver software safely and efficiently.

Key responsibilities

• Design, operate, and continuously improve highly available platform services such as managed Kubernetes clusters, Kafka, CI/CD systems, and artifact management.
• 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 for R&D teams.
• Partner with Information Security, Cost Optimization, and engineering teams to strengthen controls, improve cloud efficiency, and shape the platform roadmap.

Required profile

• Deep experience designing, operating, and troubleshooting production infrastructure in AWS (IAM, EC2, EKS, RDS, MSK, S3, Lambda, VPC, networking).
• Experience administering and scaling multi‑tenant Kubernetes clusters and streaming platforms such as Kafka in production.
• Experience building and maintaining infrastructure‑as‑code, pipeline‑as‑code, containerization, and cloud‑native systems using 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 languages such as Python, Go, Java, Scala, or shell, with a track record of owning ambiguous cross‑functional problems.
