- You consistently deliver high-quality, efficient, and well-tested code, maintaining the high standards of a strong coder with minimal bugs or rework needed after peer review.
- You proactively keep internal stakeholders fully informed on project progress, escalate potential issues strategically, and provide clear, actionable debriefs to the team following customer calls.

- Participate in and sometimes lead technical integration sessions with our customer development teams, providing expert advice and hands-on support regarding how to integrate with our platform throughout the integration lifecycle.
- Develop detailed technical specifications for integrations between our platform and our B2B customers' backend systems (including API and event mappings, data flows, etc).
- Design, implement/code, test, and deploy custom integrations, connectors, or extensions when customer requirements go beyond standard product capabilities.
- Facilitate technical integration and troubleshooting sessions with customers' engineering teams to ensure successful connectivity between our platform and theirs, following the deployment of the customer-specific integration connector.

- Build and maintain a library of compelling documentation, demos, prototypes, or Proof of Concepts (PoCs) to showcase our platform integration capabilities to accelerate the sales cycle.

- Experience in the financial services, FinTech, or mortgage technology industry is a significant advantage.

- You prefer working with legacy or simple systems over modern, complex integrations.
- You are unwilling to learn and work with Golang (Go).
