For candidates, Blitz offers exposure to real-time logistics and fulfillment problems at a scaling, venture-backed company. It says it serves 100+ brands, and its LinkedIn updates say it operates across 20+ cities. Current engineering hiring points to work with Java/Spring Boot, PostgreSQL, AWS, Kafka, React.js and Flutter across web, mobile and backend systems. The company also raised ₹28.7 crore in a 2026 pre-Series B round, while FY25 operating revenue grew 2.28x year over year.
