Job description

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

• 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.
• Maintain a high‑velocity, low‑defect release culture.
• 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.
