About the Role We’re seeking a self-driven integrations expert to design, build, and maintain complex, user-facing automation workflows on platforms like Make.com, n8n, Pipedream etc. You’ll own end-to-end API integrations—registering OAuth apps, wiring HTTP triggers, handling secrets, and scaling per-user deployments—so our customers can connect their own accounts and automate tasks without friction. What You’ll Do Build multi-step workflows : HTTP triggers, code steps (Node.js), error handling, throttling, and retries. Implement OAuth flows for external users: register custom apps, manage client IDs/secrets, store and refresh tokens securely. Automate workflow provisioning via REST API: spawn per-user workflows programmatically when they connect in our app. Parse and wire API docs quickly—map endpoints, assemble request payloads, and surface dynamic configuration (IDs, channels, sheet names) from your own metadata store. Optimize for scale and cost : fan-out fan-in patterns, debounce logic, monitor invocation quotas and plan limits. Document best practices for wiring new integrations so others can extend or maintain them. Must-Have Qualifications Software development experience, strong in Node.js . Proven track record building OAuth-based integrations (Google, Slack, Salesforce, etc.) end-to-end. Hands-on with Make.com , n8n , Pipedream , or equivalent—comfortable configuring both no-code actions and custom code steps. Experience automating workflow creation via platform REST APIs . Solid understanding of rate-limits , concurrency , and billing trade-offs when running workflows at scale. Excellent at reading dense API documentation and translating it into working integrations. Strong communication: able to turn vague requirements into clear technical designs. Nice-to-Haves Exposure to self-hosted automation platforms and the operational trade-offs vs. hosted services. TypeScript or Python experience for writing custom workflow steps. Show more Show less
