Chainalysis is the blockchain data platform trusted by organizations worldwide to investigate illicit activity, manage risk exposure, and develop innovative market solutions. The Platform Engineering team provides the shared infrastructure, tooling, and developer experience layer that powers every engineering team at Chainalysis, enabling safe and reliable software delivery at scale.
As a Senior Platform Engineer on the Foundations team, you will design, build, and operate the foundational services that enable Chainalysis engineers to deliver and run software safely. You'll 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.
Key responsibilities include:
- 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, and influence technical direction
Required experience:
- Deep production infrastructure experience in AWS (IAM, EC2, EKS, RDS, MSK, S3, Lambda, VPC, networking)
- Administering and scaling multi-tenant Kubernetes clusters and streaming platforms like Kafka in production
- Building and maintaining infrastructure as code, pipeline-as-code, containerization, and cloud-native systems (Terraform, Helm, Ansible, Jenkins, GitHub Actions, Docker, Kubernetes)
- Designing observability for production systems and tuning relational databases, ideally PostgreSQL (Datadog, Prometheus)
- Strong software engineering or scripting skills in Python, Go, Java, Scala, or shell; track record of owning ambiguous cross-functional problems
Desirable experience includes developer productivity initiatives, self-service tooling, interest in cryptocurrencies and blockchain, and experience with security standards (ISO 27001, NIST 800-171, SOC 2).
Chainalysis emphasizes AI fluency as core to how the company operates and measures performance. The expectation is that all employees develop AI capabilities, bring ideas, and collaborate to reinvent how work gets done.
