About Blitz Blitz powers India’s fastest e-commerce deliveries, enabling 60-minute and same-day fulfillment for brands like Decathlon, Adidas, Puma, and Purplle. Our systems use AI-driven logistics, real-time decisioning, and high-scale distributed architecture to deliver 98%+ success and 50% lower RTOs. We’re hiring a Senior Engineering Lead who focuses on solving problems, driving outcomes, and measuring impact. This is a hands-on leadership role for someone who owns delivery end-to-end, leads critical systems, and raises engineering excellence across teams. Role Overview As a Senior Engineering Lead, you will: • Lead multiple engineering initiatives from conception to measurable impact. • Act as a hands-on IC for critical systems — design, code, review, and debug. • Solve real business and operational problems, not just deliver requirements. • Define success metrics for every project and validate solutions through data and monitoring. • Improve reliability, observability, and performance across the tech stack. • Influence engineers through technical depth, clarity, and high execution standards. Key Responsibilities Outcome-Driven Engineering • Work backwards from the problem and architect solutions tied to clear business metrics (latency, reliability, throughput, DRR). • Measure and monitor everything — dashboards, alerts, logs, SLOs. • Iterate continuously until expected outcomes are achieved. Hands-On Technical Leadership • Write and review clean, scalable, high-quality code. • Debug production issues quickly and lead root-cause analysis. • Architect modular, fault-tolerant, and resilient systems. Execution & Process Leadership • Plan, track, and deliver multiple engineering projects on time. • Create strong engineering processes: CI/CD, testing, deployment checks, observability. • Maintain a high-velocity, low-defect release culture. Mentorship & Influence • Mentor engineers on system design, debugging, and problem-solving. • Set and enforce engineering standards for quality, clarity, and measurable impact. • Lead by example — influencing through capability, not hierarchy. Required Qualifications Technical Expertise • Graduates from IITs, NITs or other Tier-1 colleges. • 7–9 years of backend/full-stack engineering experience, with leadership responsibilities. • Strong command of Java (Spring Boot), Python (Django/FastAPI), or Golang. • Deep understanding of microservices, CQRS, DDD, and event-driven architecture. • Experience with PostgreSQL, NoSQL, Redis/Hazelcast and opensearch. • Familiarity with messaging systems such as Kafka, RabbitMQ, or AWS SQS. • Comfortable with Docker, Kubernetes, CI/CD, AWS (ECS, EC2, API Gateway, Cognito). • Knowledge of Prometheus, Grafana, distributed tracing. Leadership Experience • Led multiple engineering projects to measurable outcomes. • Strong ability to identify risks early and design preventive systems. • Experience mentoring engineers and raising technical standards. • Able to balance hands-on execution with architecture and planning. Mindset & Culture Fit • Outcome-first, not output-first. • Thinks in metrics and root causes, not assumptions. • Ownership-driven — uptime, reliability, and system health matter personally. • Thrives in fast-paced, high-accountability environments. Bonus Skills • Experience with AI-assisted development or AI agents. • Background in logistics, supply chain, fintech, or high-scale transactional platforms. • Expertise in performance engineering or incident management. Why Blitz • Contribute to systems powering millions of deliveries and decisions daily. • Be part of a culture that values speed, clarity, reliability, and impact. • Work on real-world, high-scale challenges that deliver immediate measurable outcomes. • Shape India’s next-generation commerce and logistics ecosystem.
