About The Role

Help connect a modern SaaS fintech platform to the finance tools our customers live in every day — Sage, Xero, and enterprise ERPs like SAP/NetSuite. You’ll turn messy, real-world data and APIs into reliable, observable, well-designed services that teams can trust

What You’ll Do 

● Design, build, and maintain production REST integrations in TypeScript (server-side) 

● Model & map data between our platform and third-party systems

● Handle auth flows (OAuth2, API keys), pagination, rate limits, retries, idempotency, and webhooks

● Write clean, well-tested code with clear interfaces and docs (OpenAPI/Scalar)

● Add monitoring, alerting, and structured logging to make failures diagnosable

● Partner with product and customer teams to unblock go-lives

● When useful, consume/publish events (e.g., Kafka) to debug or bypass APIs for performance

What Makes You A Great Fit 

Must-Haves 

● Bachelors/Masters degree in Engineering, Computer Science, or any other related field

● 3+ years of industry experience

● Strong TypeScript and server-side experience (Node.js or similar runtime)

● Proven track record building production-grade integrations with external APIs 

● Tests-first mindset: unit/integration tests, contract tests, and CI familiarity

● Solid debugging across HTTP, queues, and databases

Nice-To-Haves 

● SFTP pipelines & flat-file formats (CSV, XML, JSON) with schema validation

● Prior integration experience with Sage, Xero, SAP, NetSuite, etc.

● Other API styles: GraphQL, SOAP, MCP

● Event-driven architectures, especially Kafka or similar

● Secure secrets management practices

● Experience with OpenAPI generation, codegen, and Postman/Insomnia collections
