Chainalysis is the blockchain data platform trusted to investigate illicit activity and manage risk on blockchains. The Government Systems team ensures Chainalysis's most security-sensitive customers can run Reactor reliably in their own environments — including fully air-gapped networks with no internet connectivity.
Responsibilities
•Design and develop the software installer — a Go-based CLI that automates provisioning, manifest rendering, image bundling, and end-to-end deployment of Reactor to customer environments, including fully air-gapped networks
•Build and maintain the blockchain data delivery pipeline — the Java services that package blockchain data in the cloud, deliver it to customer sites, and unpack it for ingestion into the on-premises system
•Extend and improve the Admin Portal — a React-based web UI backed by a Node.js server that enables customers to manage users, roles, permissions, and monitor system health on their on-premises installation
•Develop infrastructure as code (Terraform) to provision and manage the AWS-based environments used for development, acceptance testing, and data delivery
•Collaborate with product service teams to integrate their applications into the on-prem deployment platform, defining deployment configurations, resolving environment-specific issues, and designing multi-tenancy capabilities that ensure secure isolation between tenants
•Support FedRAMP compliance requirements by designing audit logging, RBAC policies, package signing, and security hardening into the platform — writing well-tested, well-documented code with unit tests, integration tests, and CI-driven quality gates across Go, Java, and JavaScript
Requirements
•Proficiency in Java, JavaScript, Go, and Bash for building production software — services, systems-level code, and CLI tools
•Strong working knowledge of Kubernetes — deployments, networking, storage, Helm, and troubleshooting workloads in production
•Comfort working across the stack — from backend data pipelines to a React-based admin UI when needed
•Experience with infrastructure as code, particularly Terraform
•Solid Linux fundamentals (RHEL or similar — networking, storage, process management)
•A strong sense of ownership and effective cross-team collaboration
•US Citizenship due to applicable government operating requirements
