• Conduct in-depth architectural assessments of customers’ employment data pipelines and deliver actionable recommendations to reduce friction, improve reliability, and optimize onboarding performance
• Diagnose and resolve complex technical problems across authentication flows (particularly OAuth), API integrations, and data pipeline issues, exploring creative alternative solutions when standard approaches fall short
• Develop and implement customized engagement plans tailored to each account’s maturity, integration complexity, and growth potential
• Generate monitoring of key account health metrics, identify early warning signals, and take proactive action to mitigate churn risk
• Provide domain-specific guidance to developers, leveraging solid expertise in payroll, benefits, HR systems, and the broader employment data ecosystem

• Strong diagnostic skills: you can read logs, interpret error codes, trace request flows, and resolve complex API and integration issues
• A strong understanding of API design and development, including REST APIs, webhooks, OAuth, and data-portability patterns

• Excellent communication skills with the ability to context-switch fluidly across developers, business stakeholders, and executives
• Experience leading or coordinating small projects across teams—you're comfortable setting direction, defining milestones, and keeping people aligned
• Creative problem-solving instincts - you don't just follow the playbook; you explore alternative solutions and build new ones when needed
