Job Title: Senior Enterprise Integration Engineer, Supply Chain Integrations
Contract: 6 months
Location: SFO, CA (Onsite )
About The Role
We are looking for a senior hands-on integration engineer to help build and launch partner integrations across Client’s supply chain systems.
This person will work with Supply Chain, Finance Technology, Oracle SCM owners, and external partners to onboard integrations into our shared integration platform, Circuit. The work includes API contracts, partner configs, payload mappings, validation, retries, replay, logging, and production support readiness.
This is not a platform architecture role. The core platform will be owned by Client. This contractor should be able to take a partner or message type from design docs to working integration with limited day-to-day guidance.
What You’ll Do
Build partner integrations using Python, REST APIs, webhooks, SFTP, and file-based patterns.
Define and update OpenAPI contracts, YAML integration configs, and partner onboarding details.
Map partner payloads into canonical supply chain models.
Implement validation, idempotency keys, retry/replay behavior, and error handling.
Work with SaaS applications and internal APIs across various supply chain & finance functions.
Create sample payloads, test cases, and support handoff notes for each integration.
Debug failed payloads using logs, run metadata, replay tools, and partner/system responses.
Partner with business teams to clarify field mappings, required values, timing, and error cases.
Required Skills
Strong Python backend/API development experience.
Experience building enterprise integrations with REST, webhook, SFTP, JSON, XML, CSV, or flat files.
Comfortable working with OpenAPI specs and config-driven integration patterns.
Comfortable using Codex or other AI coding tools.
Experience with idempotency, retries, DLQs, replay, audit logs, and operational debugging.
Ability to read business process docs and turn them into working technical mappings.
Strong communication with both engineers and business system owners.
Can work independently and move integrations forward without needing platform-level handholding.
Nice To Have
Oracle Fusion SCM experience.
Experience building integrations that cross organizational boundaries, including B2B onboarding, external API coordination, security reviews, and test certification.
Experience with Kafka, Temporal, Databricks/Kepler, Habitat, or similar systems.
Familiarity with common business flows such as procure-to-pay, order-to-cash, record-to-report, inventory movements, fulfillment, or service operations.
Ability to travel to the SF Bay Area once a month.
