4. System Scalability & Infra

• Implement background workers, cron jobs, queues (Redis + BullMQ).

5. Finance & Reconciliation Engine

• Build COD remittance engine (expected vs received COD).
• Handle courier payout discrepancies, returns, partial remittances.
• Create reports & reconciliation logs.

6. Leadership & Culture

• Mentor tech engineers and review code quality.
• Make architectural decisions and maintain technical standards.
• Work with founders on feature planning, timelines, and execution.

• Hands-on experience with webhooks, queues, Redis, event-driven architecture.
• Experience integrating complex systems (payments, logistics, CRMs).
• Ability to solve problems independently and take end-to-end ownership.
• Understanding of SaaS multi-tenant architecture.
