ERPNext / Frappe Developer

Location: Mahape, Navi Mumbai

Job Type: Full-Time, Permanent

Experience Level: 2 – 8 Years

Requirements: 2 (Senior & Mid-Level)

About CWD

CWD Limited is an IoT-led product design and mass-manufacturing company. We build smart devices and infrastructure solutions end to end — from module and hardware design through SMT/PCBA production, box-build, testing and dispatch — across five sites (three in Mysore, two in Mumbai).

We are now consolidating the entire business onto ERPNext v16: procure-to-pay, warehouse and inventory, SMT manufacturing, quality, sales and logistics, finance, and HR/payroll. This is a ground-up digital transformation from largely manual operations to a single integrated system serving 100+ full users and 100+ shopfloor and warehouse users.

The Role

We are building an in-house ERPNext capability. You will lead the entire implementation including customizations, integrations, upgrades and day-to-day enhancements. This is a build-and-own role, not a ticket-closing role: you will sit close to production, stores, quality and finance teams and turn their processes into working software.

What you will Build

Representative work from our current roadmap

• Manufacturing (SMT/EMS): reel and feeder balance tracking with automatic component deduction against work orders; material kitting logic; MSD/ESD floor-life and dry-cabinet RH tracking; rework cost bucketing by failure stage
• Warehouse (WMS): bin and zone management, directed put-away and advanced picking (FIFO/FEFO), barcode/QR and RFID scanning on handheld terminals, 3PL stock visibility
• Quality: IQC / IPQC / OQC / PDI hold and quarantine logic that systemically blocks material movement until clearance; non-conformance and CAPA workflows; calibration and gauge tracking
• Procurement: multi-level approval workflows by value and department, vendor self-service portal, supplier scorecards, PAN validation
• Sales & planning: Available-to-Promise reporting (FG stock + WIP + RM lead time), inventory reservation against customer orders, MRP triggered from sales order balances
• Product data: firmware image, software build and license-key mapping to finished-goods serial numbers; engineering change orders linked to design-system BOMs
• Integrations: Tally, e-invoicing and e-way bill, biometric attendance across five sites, logistics/carrier portals, hardware design and PLM systems
• Traceability: cradle-to-grave serial and batch traceability across the full material flow

Responsibilities

• Design and build custom apps, DocTypes, workflows, server and client scripts, and reports on the Frappe framework
• Build and maintain REST/API integrations with third-party systems, including error handling, retries and reconciliation
• Configure standard ERPNext modules (Accounting, Buying, Selling, Stock, Manufacturing, Assets, HR, Payroll, Helpdesk) and know when to configure rather than customize
• Manage roles, permissions and user-level data access across sites and departments
• Handle data migration: master data templates, opening balances, validation and cutover support
• Own deployment hygiene — version control, staging and production environments, upgrade planning, patch management, backups
• Work directly with process owners to gather requirements, run CRP/UAT sessions, and document what was built
• Provide post-go-live support and train internal super-users

Must Have

• Hands-on ERPNext / Frappe framework development on live implementations (not just administration or configuration)
• Strong Python and JavaScript; solid SQL on MariaDB/MySQL
• Practical experience with custom DocTypes, server scripts, client scripts, hooks, scheduled jobs, custom print formats and query reports
• REST API integration experience, including authentication and payload mapping
• Git, Linux command line, and bench for site, app and environment management
• Ability to read a business process and translate it into a system design without hand-holding
• Manufacturing, EMS or discrete-industry ERP experience — SMT, PCBA, BOM management, work orders, serial/batch traceability
• Warehouse operations: barcode/RFID scanning, handheld terminals, bin and zone structures
• Indian statutory compliance in ERPNext: GST, e-invoicing, e-way bill, TDS
• Frappe HR / payroll, or Frappe Helpdesk
• Frontend work in Vue.js; experience building portal pages for external users (vendors, customers)
• Prior work migrating from Tally or legacy/manual systems
• Contributions to the ERPNext or Frappe open-source repositories
