Responsibilities
Design and develop integration platform infrastructure - adapter layer APIs, event-driven systems, workflow orchestration engines, authentication services across enterprise applications
Lead technical decision-making on integration architecture patterns, API design for platform consumers, and distributed systems trade-offs
Build full-stack capabilities across backend integration services and frontend interfaces
Collaborate across Product, Sales, Tech Services, and Engineering teams to understand integration requirements and deliver solutions
Own feature delivery from conception through production deployment
Debug and resolve complex integration issues: OAuth flows, webhook delivery failures, rate limiting scenarios, message queue problems, third-party API connectivity
Establish technical standards and best practices for integration development through code review, documentation, and team guidance
Improve development workflows: CI/CD pipelines, testing strategies for third-party API interactions, and observability infrastructure
Mentor team members on integration platform thinking, distributed systems design, and OAuth authentication patterns
Qualification
Required
Strong backend experience with Ruby on Rails building production integration systems
Solid frontend skills with React and TypeScript. You ship features across the stack
Experience with distributed systems like message queues (RabbitMQ, Kafka, SQS), async processing, idempotency, eventual consistency
You've deployed and operated production services on AWS (Lambda, RDS, SQS, S3)
PostgreSQL proficiency including schema design, query optimization, multi-tenant data handling
You've built APIs that other engineers use. You understand webhooks, polling systems, and event processing
Deep knowledge of integration mechanics like OAuth2 across different enterprise systems, webhook reliability, credential management, rate limiting, handling third-party API failures
Product sense for integrations. You can figure out which integrations actually matter to customers, understand enterprise workflows, and translate customer problems into integration solutions
Track record shipping integration features end-to-end. You've debugged OAuth flows that mysteriously break, webhooks that stop firing, or data sync conflicts
You make teammates better through code review and sharing what you've learned. You help people think about integration architecture, not just build one-off connections
You make good calls with incomplete information and changing requirements
You use AI tools (Cursor, Copilot, Claude) to work faster and experiment with new capabilities
Preferred
You've built integration platform infrastructure or iPaaS products before
Prior work at integration-focused companies (Zapier, Workato, Tray.io, MuleSoft, Segment)
Experience with GraphQL, gRPC, or other API styles
