Backend Engineer Intern

Backend Intern to Full-Time Opportunity

HelioAI (helioai.tech)

HelioAI is building a reliable AI concierge for Shopify brands, helping shoppers get accurate answers, discover products faster, and complete purchases with confidence, while reducing support workload for brands.

We’re looking for a Backend Intern with hands-on Node.js experience who can dedicate 6–8 hours a day and wants to work on real production systems across Shopify + AI infrastructure.

This role begins as a 4-month internship. Based on performance, consistency, and ownership, it can be converted into a full-time role. The same structure applies to compensation as well: an internship stipend during the first 4 months, followed by a revised full-time salary upon conversion.

Fresh graduates are welcome too if you’ve built real projects, enjoy solving backend problems, and love shipping fast.

What you’ll do

Build backend services using Node.js + TypeScript

Integrate Shopify Admin APIs (REST/GraphQL) and webhooks

Create reliable workflows with retries, rate limits, and idempotency

Work on caching, background jobs, and performance improvements

Improve logging, monitoring, and backend stability

Ship small, clean PRs with clear updates and consistent delivery

What you’ll work on

Shopify onboarding, store sync, and webhook pipelines

Billing and usage tracking across monthly and variable plans

Conversation-to-order attribution infrastructure

AI-powered tools for catalog fetch, order status, policies, and FAQs

Skills we’re looking for

Strong basics in Node.js, TypeScript, Express/Fastify

Working knowledge of MongoDB or Postgres

Understanding of Redis and caching fundamentals

Good debugging mindset and clean coding habits

Bonus if you’ve worked with BullMQ, queues, GraphQL, or Shopify apps

Why this role

Work on real production systems, not dummy assignments

Ship features weekly and learn by building

Get direct exposure to AI + ecommerce infrastructure

Opportunity to move from internship to full-time based on performance
