Job Description

Do you want to work in Advertising, solving an industry-defining problem using advanced technology, working at the intersection of Engineering and Science?

Amazon is shaping the future of Advertising and our team is leading a part of that effort. We are seeking a passionate engineer who can help build an exciting new advertising product for Amazon. Contextual Advertising is an exciting new frontier for the advertising industry , with the deprecation of critical identifiers used by advertising such as cookies. We are building an industry leading solution to this interesting problem and disruptive opportunity.

Advertising at Amazon is a fast-growing multi-billion dollar business that spans across desktop, mobile and connected devices; encompasses ads on Amazon and a vast network of hundreds of thousands of third party publishers globally. Comet, Amazon Ads’ contextual signal service, powers ad programs across Amazon by providing contextual signals from 3P offsite and 1P properties beyond the Amazon Store, leveraging a combination of home grown and 3P vendor solutions. The team owns extraction and generation of a wide range of contextual signals using the latest in generative AI and engineering. Comet also sources contextual signals directly from Amazon owned publishers (IMDb) and 3P vendors. To do all this ,the Comet team builds large-scale real-time transactional solutions, batch and stream processing systems, internet scale crawling solutions and storage infrastructure. We process bid requests in the orders of tens of billions per day with our real-time, batch and stream processing systems. We are not tied to one technology. Instead, we use what is best suited for the purpose. All of our systems tend to be loosely coupled, communicating using synchronous and asynchronous messaging, leading to a classic distributed processing architecture. All our systems need to also implement complex machine learning and optimisation algorithms at scale.

Our team is creating key infrastructure to enable Amazon’s build out of contextual solutions for our customers. We are looking for a software development engineer to work on this new initiative that involves building highly available, efficient and low latency internet scale infrastructure including web-scale crawler, contextual processing and classification systems, data storage and vending solutions that will be used across multiple contextual advertising use cases. As an SDE2, you will be responsible for designing, developing and evolving the architecture of these systems, collaborating with the team for software development lifecycle activities and mentoring other engineers.

Key job responsibilities
1. Design and code right solutions starting with broadly defined problems.
2. Drive best practices and engineering excellence.
3. Work with other team members to develop the architecture and design of new and current systems.
4. Work in an agile environment to deliver high quality software.- 2+ years of non-internship professional software development experience
- 2+ years of non-internship design or architecture (design patterns, reliability and scaling) of new and existing systems experience
- Experience programming with at least one software programming language
