Senior Integration Engineer

Required

• You are a great fit if you have:
• Hands-on experience with our backend stack: Python, FastAPI, SQLAlchemy, and Pydantic, with a track record of shipping production data pipelines and integrations.
• Deep experience integrating third-party systems: REST, SOAP, and query-language APIs (think NetSuite SuiteQL), OAuth and credential management, rate limits, pagination, and the undocumented quirks every ERP hides. You've built connectors that survived contact with real customer data.
• A strong instinct for pipeline design: fetch, validate, normalize, upsert, built idempotent and re-runnable, with clean schema boundaries between the remote system's world and ours.
• Proficiency in SQL, writing high-performance queries and bulk upserts despite billions of data points for even a single customer.
• Respect for the write path: pushing AI-approved actions into a customer's ERP demands safety rails, dry runs, failure capture, and auditability.
• A habit of building for operability: structured logging, sync-run tracking, and alerting (we use PagerDuty) so failures are caught, triaged, and attributed, including telling an external stakeholder when the error is on their side.
• Claude Code, Codex, and OpenCode are your best friends. You know how to parallelize instances to make sure we're shipping 24/7, even while you sleep, and you know the ins and outs of each of them at any time.
• Excited to work directly with CPG operators and their IT teams, owning integrations end to end, from scoping a customer's ERP setup to shipping and operating the sync that runs their business.
• Motivated by the chance to join an exceptionally ambitious, high-ownership team that moves quickly, holds a high bar, and is determined to build a company that makes history.
• Bonus: NetSuite experience, background task orchestration (Hatchet, Temporal), unstructured data ingestion and AWS.
