Web3 Senior Technical Solutions Engineer

Chainalysis is seeking a technically strong, customer-focused Senior Technical Solutions Engineer to serve as the escalation point for complex product and integration challenges across the Chainalysis platform. The role is focused on API troubleshooting, data operations, deployment support, and customer partnership — with additional responsibility for On-Premises deployment and maintenance workflows.

This individual will work directly with customers and internal teams to diagnose and resolve technical issues, guide clients through connecting their products to ours via our APIs, and execute data operations that keep our customers running smoothly. For our On-Premises customers, when needs arise, they will step in to deploy, maintain, and troubleshoot customer environments with confidence. Success in this role requires deep technical capability, an understanding of blockchain and crypto compliance workflows, and an exceptional ability to communicate clearly with both technical and non-technical audiences.

In this role, you'll:

• Serve as the escalation point for complex technical issues across the Chainalysis product suite, including KYT (Know Your Transaction), Reactor (Cloud and On Premises), Data Solutions, and related APIs.

• Act as a technical resource during customer deployment projects, guiding clients through On Premises and API integration design, onboarding, and go-live.

• Diagnose and resolve API integration issues including authentication errors, rate limiting, timeout failures, and unexpected response behaviors.

• Execute bulk data operations using internal scripts and SQL, including data deletions, alert closures, transaction exports, and user migrations.

• Support data migration efforts, including bulk loading of historical transactions, organization-to-organization migrations, and legacy data imports.

• Advise customers on SSO/Identity integration (OIDC, SAML, Okta) and platform configuration best practices.

• Investigate data discrepancies, transaction processing failures, alert anomalies, and blockchain-specific issues across multiple networks and asset types.

• Develop and maintain working knowledge of blockchain networks, asset types, and protocol-specific behaviors to support customer investigations and troubleshoot chain-specific issues.

• Manage the On-Premises deployment lifecycle, including installation, infrastructure planning, data ingestion, version upgrades, and ongoing maintenance.

• Troubleshoot On-Premises server issues including data ingestion failures, service outages, data update delays, and resource constraints.

• Work within security-sensitive and restricted-access environments, including airgapped networks and law enforcement or government customer deployments.

• Support customers through On-Premises version upgrades and cloud migration planning, ensuring minimal disruption and data continuity.

• Travel to client sites as needed (approximately 15%) to support On-Premises software installations, upgrades, and critical maintenance.

• Create and maintain technical documentation, runbooks, and SOPs that enable customers and internal teams to resolve common issues independently.

• Collaborate closely with internal Product, Engineering, and Customer Success teams to escalate bugs, communicate customer feedback, and support feature rollouts.

• Mentor and train support agents and peers on technical processes, tooling, and SOPs.

We're looking for candidates who have:

• 5+ years of experience in a technical support, solutions engineering, systems engineering, or similar customer-facing technical role.

• Demonstrated ability to independently own and drive resolution of complex, multi-stakeholder technical issues from initial triage through to completion.

• Diagnosed and resolved complex technical issues in a customer-facing support, solutions engineering, systems engineering, or similar role.

• Guided customers through API integrations, including reading API documentation, troubleshooting HTTP requests/responses, and advising on integration architecture.

• Written and executed SQL queries for data investigation, extraction, and bulk operations.

• Built scripts or automation (Python, Bash, or similar) to perform bulk data operations and streamline repetitive tasks.

• Communicated complex technical concepts to both technical and non-technical audiences across customers, support teams, and engineering.

• Operated successfully in fast-paced, ticket-driven environments requiring the ability to prioritize and manage multiple concurrent issues, including urgent escalations.

• Supported a global customer base across multiple time zones, adapting communication >

• Deployed, maintained, or troubleshot server-based or On-Premises software in customer environments with restricted access.

• Comfort working within security-sensitive environments, including law enforcement, government, or classified customer deployments.

• Ideally supported cryptocurrency compliance workflows, such as transaction monitoring, alert triage, or sanctions screening.

Technical Skills:

• Strong proficiency in SQL and scripting languages (Python, Bash) for data analysis, bulk operations, and automation.

• Experience troubleshooting REST APIs and guiding customers through integration design and deployment.

• Experience working with large-scale transaction data and compliance alerting systems, including alert triage, bulk operations, and data quality investigation.

• Expertise in Linux server administration, including CLI diagnostics and log analysis, with demonstrated ability to perform guided, remote troubleshooting and diagnostics in environments with severely limited visibility and restricted access.

• Solid knowledge in hardware procurement, server deployment, systems performance tuning, and data center operational protocol compliance would be an advantage.

• Familiarity with containerization and orchestration technologies (Docker, Kubernetes) and infrastructure capacity planning.

• Ability to quickly develop deep expertise in Chainalysis products to map them to customer compliance and operational needs.
