Senior Engineering Lead

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.

• •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.
