Chainalysis; New York (NY); On-site; USD 180,000 - 240,000; Full time

Job summary

Chainalysis is seeking a Senior Platform Engineer to design, operate, and optimize core platform services across AWS, Kubernetes, and streaming systems. You’ll own complex incidents, drive reliability, and build self-service tooling for engineering teams.

Join a security‑conscious, AI‑driven environment where you collaborate across Security, Cost Optimization, and R&D to raise platform standards and scale globally while reducing toil.

Qualifications

• Deep experience designing, operating, and troubleshooting production infrastructure in AWS, including 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 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 Python, Go, Java, Scala, or shell, plus a track record of owning ambiguous cross-functional problems and communicating tradeoffs clearly

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
