Lead Software Engineer

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 fromIITs, NITs or other Tier-1 colleges.
• 8–10 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.
