Who We Are

Faxtor (www.faxtor.in) builds custom ERP and CRM software for Indian SMEs — sales automation, operations tracking, workflow management, and more. We work across multiple industries including manufacturing, real estate, education, lending, and export businesses.

We don't resell off-the-shelf tools. We build things that actually fit the way a business works —

fast, on a proprietary delivery platform we've built in-house. Role Description

We're hiring a Backend Developer to build and maintain the core logic of our ERP/CRM platform in PHP, and to own the integrations layer — payment gateways, WhatsApp, email, Aadhaar/eKYC, digital signatures, and AI-powered features. This isn't repetitive CRUD work — every client is different, and a positive chunk of the job is wiring up real-world APIs correctly and reliably.

What You'll Do Build and maintain backend logic and APIs in PHP

Design and optimize MySQL schemas and queries across multiple client projects

Use Redis for caching, queues, and session management

Integrate and maintain WhatsApp Business API workflows — notifications, automation, two-way messaging

Integrate transactional email and automation triggers

Integrate payment gateways end-to-end — webhooks, reconciliation, refunds, failure handling

Integrate Aadhaar/eKYC validation APIs

Integrate digital document signature (e-sign) APIs

Build AI-powered features into the product — calling LLM APIs (OpenAI, Anthropic, or similar) for automation, document processing, or assistive workflows

Work with the frontend team and client-facing team to ship complete features, not just backend pieces You're the Right Fit If... You have strong,



hands-on PHP experience — you understand the language, not just a framework

You can design a MySQL schema that holds up as data and usage grow

You've used Redis for more than basic caching — queues, rate limiting, sessions

You've integrated at least one payment gateway end-to-end, not just followed a tutorial

You've worked with Aadhaar/eKYC or e-sign APIs — or you're confident reading unfamiliar government/compliance API docs and getting it right

You've built something real using an AI API — a chatbot, document automation, an assistive feature, anything shipped

You can work across multiple live client projects without losing track of what's where Backgrounds that fit well: Backend developer at a software services or product company

Full-stack developer who has owned backend/integration work

Developer with fintech or govtech exposure — payment gateways, KYC, and e-sign are common there What We Offer Compensation as per industry standards — based on your experience and skill

WeWork Koramangala, Bangalore (open to remote for strong candidates)

Direct access to founders and the tech team — fast decisions, no bureaucracy

Real integration work across payment, government, messaging, and AI APIs — not one repetitive stack

Growing team where your code ships and is used immediately Requirements added by the job poster
