About the role

Description

Amazon Now (Quick Commerce) — is one of Amazon's largest and fastest-growing businesses, operating across 8+ marketplaces (India, MENA, North America, EU, UK, Japan) and powering adjacent businesses like India Fresh and Healthcare. The platform handles >0.7MM orders/day, scaling to 2MM by year-end.

As an SDE2 on the Tez CX PIXEL team, you would work at the heart of Amazon Now's quick commerce platform. IXEL owns the end-to-end in-store shopping experience, from homepage and browse surfaces through personalization, live cart, single cart and checkout, deals and value surfacing, AI-driven merchandising, and geospatial CX.

The systems are Tier 1, serving 2,000+ TPS as the canonical worldwide platforms for shopping, ordering, and savings. The role directly impacts conversion, basket size, and checkout completion — the metrics that turn platform growth into revenue. The defining product shift ahead is the adaptive, agentic store — moving from a fixed storefront to one that intelligently composes itself around each customer's habits, context, and intent, making this a compelling charter for an SDE2 looking to drive high-impact, customer-facing systems at scale.

Key job responsibilities

  • You solve difficult problems, applying appropriate technologies and best practices.
  • You work with your team to invent, design and build software that is stable and performant.
  • You are proficient in a broad range of design approaches and know when it is appropriate to use them (and when it is not). Your solutions are pragmatic.
  • You consider the legacy of the code you produce and write code that an SDE unfamiliar with the system can understand.
  • You limit the use of short-term workarounds. You do things with the proper level of complexity the first time (or at least minimize incidental complexity).
  • You create flexible software without over-engineering. You make appropriate trade-offs, re-use where possible, and are judicious about introducing dependencies.
  • You are efficient with resource usage (e.g., system hardware, database, memory/CPU, etc.)
  • You work on project ideas with customers, stakeholders, and peers

Technical questions 5
What is the difference between WHERE and HAVING clauses in SQL? Answer
Model answer: WHERE filters rows before any groupings are applied, while HAVING filters aggregated groups after GROUP BY has executed.
Explain SQL Window functions: ROW_NUMBER(), RANK(), and DENSE_RANK(). Answer
Model answer: ROW_NUMBER() assigns unique sequential integers. RANK() assigns identical ranks to ties and skips ranks. DENSE_RANK() assigns identical ranks to ties without skipping rank numbers.
How do you handle NULL and missing values during data cleaning in Python/Pandas? Answer
Model answer: Use .isna().sum() to identify missing values. Impute with mean/median using .fillna() or remove with .dropna(subset=[...]) depending on variance impact.
What is the difference between Star Schema and Snowflake Schema in Data Warehousing? Answer
Model answer: Star Schema has denormalized dimension tables directly connected to the central Fact table. Snowflake Schema normalizes dimension tables into sub-dimensions to minimize redundancy.
How do you calculate MoM (Month-over-Month) growth in SQL? Answer
Model answer: Use LAG(revenue, 1) OVER (ORDER BY month) to fetch the previous month's revenue and compute (revenue - prev_revenue) / prev_revenue * 100.
