Javascript Developer

Node.js + Google Apps Script Developer

Devsatva LLP · Ahmedabad, Gujarat (Hybrid) · Full-time · 1–2 years experience

About Devsatva

Devsatva is an Ahmedabad-based data engineering and AI consultancy building production-grade data pipelines, agentic AI systems, MCP servers, and e-commerce automation for clients.

The Role

We're hiring a developer who is comfortable moving between Node.js backends and Google Apps Script automations. You'll build the glue that connects Google Workspace, marketplaces, storefronts, and internal tools for our clients — from lightweight Sheets-based catalog and order dashboards to full marketplace integrations and MCP tool endpoints.

What you'll actually do

• Build and maintain Node.js services, APIs, and background workers (Express/Fastify, TypeScript preferred)
• Write Google Apps Script for Sheets, Gmail, Drive, and Forms — custom functions, time-based and event triggers, web apps, and bound scripts
• Integrate e-commerce APIs — Amazon SP-API, Shopify Admin API, WooCommerce, Flipkart Marketplace, and similar — with proper auth, retries, and rate-limit handling
• Build catalog sync, inventory reconciliation, order pipelines, and reporting flows across marketplaces, storefronts, and client ERPs
• Wire up data flows between Google Workspace, marketplace seller accounts, and our data warehouses
• Own small features end-to-end: scope → build → deploy → monitor
• Write clean, documented code that a teammate can pick up cold

Must-have

• 1–2 years hands-on with Node.js in production (not just tutorials or coursework)
• Solid JavaScript/TypeScript fundamentals — async/await, promises, npm ecosystem
• Working knowledge of Google Apps Script — SpreadsheetApp, GmailApp, DriveApp, UrlFetchApp, PropertiesService, triggers, deployable web apps
• REST API integration experience — OAuth 2.0, webhooks, retries, idempotency, pagination
• Comfort reading marketplace/e-commerce API docs and handling their quirks (throttling, report-based endpoints, async job patterns)
• Git-based workflow (branching, PRs, code review)
• Clear written English for docs, PRs, and client-facing tickets

Nice-to-have

• Hands-on with Amazon SP-API (Orders, Catalog Items, Feeds, Reports, FBA Inventory) or legacy MWS
• Shopify Admin API, Shopify Functions, or storefront app development
• Experience with Indian marketplaces — Flipkart, Meesho, Myntra, Ajio
• Familiarity with payment gateway integrations (Razorpay, Stripe, PayU)
• ERP / inventory tools — Unicommerce, EasyEcom, Vinculum, Zoho Inventory
• Google Cloud Platform (Cloud Functions, Cloud Run, BigQuery, Pub/Sub)
• Exposure to MCP (Model Context Protocol) servers or agentic tooling
• SQL comfort and basic data modeling
• Docker basics
• Experience with clasp for Apps Script version control

What we offer

• Direct exposure to enterprise and D2C clients and real production systems from day one
• Mentorship from senior data and AI engineers
• A fast learning curve — you'll ship things that get used, not sit in a Jira backlog
• Competitive salary aligned with experience
• Work from our Ahmedabad office
