Marketplace Integration Lead for Saudi Embedded Finance Platform (Integration + Knowledge Transfer)

ABOUT US SAVI (savi.sa) is an API-first embedded finance and payment orchestration platform for Saudi digital marketplaces. We give a marketplace one integration for seller onboarding and verification, split payments, a reconciled ledger, escrow and seller payouts. Funds always stay with SAMA-licensed payment providers and banks. The platform is built and running. Our stack is Node.js/NestJS (TypeScript), PostgreSQL with Prisma, Redis/BullMQ, and Next.js portals, hosted in-Kingdom. THE CHALLENGE Our first marketplace customers are ready, but integrations are slow. The marketplaces' IT teams are not yet ready to integrate, and our small team is stretched. We need one senior integration expert to run the first marketplace integration to go-live, and to leave our team able to repeat it without him or her. SCOPE OF WORK 1. Integration discovery: Review our APIs, docs and sandbox. Run a technical kickoff with the marketplace's IT team and agree an integration plan, owners and timeline. 2. Integration lead: Lead the first marketplace integration end to end: seller onboarding and verification, payment and split flows, webhooks, payouts, reconciliation, and escrow where applicable. 3. Marketplace-side support: Guide the marketplace's developers (sample code, request/response examples, error handling, idempotency, webhook signature verification) and unblock them quickly. 4. Testing and go-live: Run sandbox testing with the marketplace's test data, agree an acceptance checklist, then support the pilot go-live and the first live transactions. 5. Gap fixing: Where the integration exposes gaps in our APIs or docs, fix small items directly or specify them precisely for our developers. 6. Knowledge transfer: Pair with our CTO and full-stack developer throughout. Hand over a reusable integration playbook covering an onboarding checklist, a standard integration guide with sample code, a testing and go-live checklist, and a troubleshooting guide. Run two recorded training sessions so our team can run the next integration alone. DELIVERABLES - A signed-off integration plan - A working, tested integration in production or pilot - The acceptance checklist, completed - The integration playbook and sample code in our repository - Two recorded training sessions - A short handover report with lessons learned and recommended improvements for self-serve integration MILESTONES (fixed price) - Milestone 1: integration plan, sandbox integration working, marketplace kickoff done. - Milestone 2: go-live, playbook, training sessions and handover accepted. IDEAL CANDIDATE - 5+ years integrating payment, payout or marketplace systems (Stripe Connect, Adyen for Platforms, or a Saudi/GCC PSP style) - Strong with REST APIs, webhooks, idempotency, ledgers and reconciliation - Comfortable working directly with client IT teams, and good at teaching - Experience in Saudi Arabia or the GCC strongly preferred; Riyadh-based or Arabic-speaking is a plus - Able to start immediately and work fast - Willing to sign our NDA before receiving internal documentation OUT OF SCOPE A full rebuild of our platform, legal or regulatory advice, and building the public developer portal (possible later work).
