  • Collaborate with product managers, QA engineers, and other developers throughout the software development lifecycle.
  • Produce clear technical documentation for APIs, integration workflows, and implementation details.
  • Follow best practices for secure credential management, dependency management, and application security.
  • Contribute to CI/CD pipelines and deployment automation.

Nice to Have

  • Build and maintain automation workflows using n8n, Make, Zapier, or similar workflow automation platforms.
  • Develop custom n8n nodes or connectors.
  • Implement webhook-based integrations and event-driven workflows.
  • Experience contributing to open-source integration projects.

  • 3+ years of JavaScript and TypeScript development.
  • 2+ years of Node.js development.

  • Experience with Git and modern package management tools (npm or pnpm).
  • Experience writing automated tests using Jest, Playwright, or similar frameworks.
  • Strong understanding of JSON, API payloads, and schema validation.
  • Excellent debugging and problem-solving skills.

Preferred Qualifications

  • Experience with workflow automation platforms such as n8n, Make, Zapier, or Power Automate.
  • Experience building custom connectors or plugins for automation platforms.
  • Familiarity with webhook-based integrations.
