Ruby Labs is building a payment orchestration system consisting of:

• A JavaScript frontend SDK for payment forms
• A Golang backend API
• An internal CRM

Our platform is integrated into multiple products and workflows, where correct integration, clear documentation, and fast feedback are critical to successful payment processing.

We are looking for an Integrations Engineer who will act as the technical bridge between our platform and the products integrating it. This role combines frontend engineering, integration support, product understanding, and customer‑facing communication.

In this role, you will:

• Work closely with internal and external product teams integrating our payment solution
• Help products correctly integrate our frontend JavaScript SDK and backend APIs
• Be deeply familiar with how our system behaves in real‑world integrations
• Feed real integration issues, edge cases, and gaps back to the engineering team

This is not a classic support role — you will write code, read code, debug integrations, and help shape both the SDK and the documentation based on real usage.

You will be the person who:

• Helps products embed and configure our payment form SDK
• Answers integration questions in support channels
• Tests integrations and reproduces issues
• Distinguishes bugs vs incorrect usage vs documentation gaps
• Ensures our documentation matches actual API and SDK behavior

You will work closely with backend engineers, frontend SDK developers, and product managers to improve integration quality and developer experience.

• Assist product teams in integrating the JavaScript payment SDK into their frontend applications.
• Help configure payment flows, callbacks, and error handling.
• Monitor support channels (Slack, tickets, shared chats, etc.).
• Answer technical questions related to SDK usage and API behavior.
• Guide teams through best practices for secure and reliable integrations.

• Reproduce reported integration issues locally or in test environments.
• Debug frontend and API-related issues across:
  • JavaScript SDK
  • Backend Golang API
  • CRM and configuration interfaces
• Identify whether an issue is:
  • A real bug
  • Incorrect integration or usage
  • Missing or unclear documentation
• Escalate confirmed bugs to the development team with clear reproduction steps and context.

• Review and validate API and SDK documentation against real system behavior.
• Keep documentation in sync with current SDK and API versions.
• Identify missing examples, unclear explanations, or misleading flows.
• Proactively improve developer‑facing docs based on integration feedback.

• Use and understand the internal Next.js CRM.
• Help configure products, payment flows, and settings via the CRM.
• Provide feedback to the CRM team on usability gaps or missing functionality.
• Occasionally implement small frontend improvements if needed.

• Act as the voice of integrators and product teams inside Ruby Labs.
• Share recurring issues, friction points, and improvement ideas with engineering and product.
• Help prioritize fixes and improvements based on real‑world impact.
• Contribute to improving overall developer experience of the platform.

• Strong experience with JavaScript / Type Script and frontend integrations.
• Experience working with frontend SDKs or third‑party APIs.
• Ability to read and understand backend APIs (REST, JSON, auth flows).
• Comfort debugging issues across frontend and backend boundaries.
• Strong communication skills and ability to explain technical concepts clearly.
• High ownership mindset — you care about integrations actually working in production.

• Experience in payments, fintech, or checkout flows.
• Experience with React / Next.js.
• Familiarity with Golang…
