About the job

Backend Engineering Intern (Node.js / TypeScript / Supabase)

Position Summary

We are seeking a Backend Engineering Intern with strong fundamentals in Node.js and TypeScript to join Irnofic's founding team. Irnofic is building a multi-tenant AI WhatsApp SaaS platform — powering autonomous AI assistants for businesses on WhatsApp. You will work directly on the core infrastructure: webhook pipelines, multi-tenant data isolation, background job queues, and AI orchestration with Claude. This is production-grade work on a live system.

If you want 6 months of real SaaS backend experience that you can point to — this is it.

Key Responsibilities

Build and maintain webhook handlers that receive, verify, and process WhatsApp messages from Gupshup at scale.
Write Supabase (PostgreSQL) queries, design schema changes, and implement Row Level Security policies for tenant data isolation.
Integrate and maintain background job queues using Trigger.dev for broadcasts, reminders, and scheduled automation.
Implement per-tenant rate limiting using Upstash Redis with sliding window counters.
Work with the Claude AI API — structuring prompts, handling tool use blocks, and building the tool executor pipeline.
Write idempotency logic to prevent duplicate message processing on webhook retries.
Participate in code reviews, architecture discussions, and sprint planning.

Required Skills / Qualifications

Solid working knowledge of Node.js and TypeScript.
Comfortable writing SQL — joins, filters, inserts, indexes.
Understands REST APIs and webhooks — has handled an inbound POST request before.
Has built something real, even a personal or college side project.
Git basics — branching, pull requests.
Knows why an API key must never appear in frontend code.

Preferred Skills / Experience

Any hands-on experience with Supabase or PostgreSQL.
Exposure to Redis or any queue/job system (BullMQ, Trigger.dev, etc.).
Familiarity with HMAC signature verification or webhook security patterns.
Experience consuming third-party APIs (any platform — payment, messaging, etc.).
Basic understanding of multi-tenancy and data isolation concepts.
