HUMAN is seeking an Enterprise Customer Success Engineer to lead complex customer integrations across EMEA. You will serve as a trusted technical partner throughout the integration lifecycle—from implementation planning and deployment through validation, tuning, optimization, and ongoing support. In this role, you will own the technical delivery of complex enterprise integrations, including implementation planning, configuration, validation, troubleshooting, and launch readiness. You'll lead customer-facing technical meetings, kickoff sessions, integration reviews, and issue-resolution calls. You'll translate customer architecture, use cases, traffic patterns, and security objectives into clear integration plans, partnering with internal tuning teams. You'll guide customers through API, SDK, server-side, client-side, and console-based implementation activities. You'll run integration health checks, baseline validation, detection reviews, and basic tuning adjustments, escalating complex requirements to the tuning team. Using logs, telemetry, dashboards, and diagnostic tools, you'll investigate technical issues and establish clear entrance and exit criteria for integration activities. You'll maintain accurate Jira records with scope, technical context, validation results, and open issues. You'll partner with Technical Account Managers to provide customer-ready updates, health summaries, and progress reports. You'll coordinate escalations with Engineering, Product, Operations, Detection, and Research teams, ensuring issues are clearly documented and actively followed through to resolution. You'll identify recurring implementation challenges and turn structured feedback into requirements for better product capabilities, documentation, tooling, and reusable playbooks. You'll help improve the scalability of Customer Success Engineering through automation, standardization, and repeatable processes, while serving as a technical subject-matter expert and mentor to the broader CSE team. You bring 3-5 years of experience in customer-facing technical roles such as Customer Success Engineering, Solutions Architecture, Technical Account Management, Sales Engineering, or Professional Services. You have demonstrated experience leading complex enterprise software, security, fraud, ad-tech, or infrastructure integrations. You understand web applications, APIs, SDKs, HTTP, JavaScript, JSON, and common integration patterns. You're comfortable troubleshooting customer environments using browser developer tools, Postman, logs, dashboards, and API documentation. You have practical experience with configuration, traffic analysis, validation, and performance optimization. You can analyze ambiguous technical problems, identify root causes, and drive issues to resolution across multiple teams. You communicate clearly with engineers, operators, business stakeholders, and executives. You excel at project management, prioritization, and managing multiple enterprise customers with competing priorities. You're self-motivated, highly organized, curious, and comfortable in changing environments. You're fluent in English and can collaborate effectively across EMEA and global teams.
