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 a Frontend Forward-Deployed Engineer (FDE) 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.

SDK Integration & Customer Support

• 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.

Debugging & Issue Triage

• 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.

Debugging & Issue Triage

• 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.

Internal Tooling & CRM

• 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.

Feedback Loop & Product Impact

• 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 APIs.

• Experience improving developer documentation.

• Previous experience in a Forward-Deployed Engineer, Solutions Engineer, or Integration Engineer role.

• You enjoy working close to real users and real problems.

• You’re pragmatic and solution-oriented.

• You can switch between code, docs, and conversations seamlessly.

• You know when to elevate a bug — and when to fix confusion with a good…
