Join our team as a Senior Engineer (Integrations) where you will architect and develop complex, high-volume integrations with third-party systems. You will own the integrations foundation end to end, debug and support live integrations, scale our systems, ensure reliability, participate strategically, and collaborate cross-functionally.

Proficiency in TypeScript and Node is required, along with 8-12 years of full-stack development experience.
Missions
- Architect and develop complex, high-volume integrations with third-party systems, ensuring scalability and reliability.
- Own the integrations foundation end to end, including self-serve setup, scalability, rate limiting, retries, and observability into integration health.
- Debug and support live integrations, getting hands-on with troubleshooting and maintaining integrations in production.
Profil recherché
- Experience with API design and lifecycle - public/external APIs, API versioning, OAuth/authentication- Architecturally-minded, with strong experience in data schema modeling and comfort across relational databases
- You use AI tools to move faster, but you know where to draw the line. You can read and reason about generated code rather than shipping it blind, and you know when a problem needs your own judgment instead of a prompt
- Strong grasp of data synchronization strategies: ETL, data normalization, webhooks and polling, idempotency, rate limiting/throttling, back-off and retry logic, dead-letter queues
- You know how to instrument a system so failures surface before a customer notices, and you can reason about infrastructure trade-offs (scaling workers, managing queue backpressure, isolating failures) without needing a dedicated DevOps team to hold your hand
- Comfortable on customer calls - debugging live issues and gathering integration requirements directly from customers
- Deep experience building read/write integrations to third-party systems, including transferring large volumes of data daily with systems you don't own
- Highly proficient in TypeScript and Node (Express)
- 8-12 years of full-stack development experience, roughly 80% backend / 20% frontend
- Experience with scheduled job/worker and queue systems (Prisma, BullMQ, SQS, RabbitMQ, or similar)
