Tavco Growth Private Limited is a marketing analytics and digital strategy firm building high-throughput marketing automation workflows and custom data architecture to eliminate operational friction for scaling brands.

Role Overview

We are hiring a sharp, self-reliant Technical Intern to build, scale, and optimize our multi-tenant CRM backend. Full-time commitment is strictly required—you must have already graduated or completed your final exams. We do not hire part-timers or current students with ongoing academic commitments. You are expected to hit the ground running with zero hand-holding on the basics.

Key Responsibilities

• CRM Backend Development: Design and maintain backend services and automation scripts for a multi-tenant CRM platform.
• Database Management: Construct PostgreSQL database schemas and enforce strict security policies to guarantee data isolation.
• API Integrations: Build custom API integrations and webhooks connecting external marketing platforms, messaging channels, and lead generation tools into the CRM pipeline.
• AI & LLM Cost Optimization: Audit and optimize AI prompts and LLM API calls to process, summarize, and categorize customer data at minimal token costs.
• Pipeline Debugging: Identify logic errors or performance bottlenecks in active pipelines, verifying multi-tenant isolation rules during deployment.

Qualifications & Mandatory Requirements

• Availability: Graduated or finished with all final exams. Must be available for full-time work immediately (no part-time options).
• Database Systems: Practical understanding of relational databases (MySQL, PostgreSQL), schema design, and datatypes.
• API & Backend Scripting: Solid OOP principles and hands-on experience in Node.js/TypeScript (or Python) to build RESTful APIs, background workers, and webhooks.
• Security & Multi-Tenant Logic: Clear grasp of tenant context management (session handling, context-bound DB transactions) to prevent cross-tenant data leaks.
• AI Resource Efficiency: Familiarity with prompt structure, model selection, and token optimization techniques to manage API costs.
• Mandatory Workstation: Personal laptop/workstation capable of running local backend services, Docker containers, and database tools smoothly.
• Capability over Credentials: Proven ability to build, debug, and ship real projects independently.

Stipend & Career Growth

• Months 1 to 6: ₹7,000 / month
• Post 6 Months (PPO Conversion): Up to ₹5,00,000 PA (Full-time Core Team, performance-based)

Location & Benefits

• Location: Hybrid remote in Kharghar, Navi Mumbai, Maharashtra
• Perks: Paid time off (PTO)
