We’ve already transformed the way businesses approach e-commerce and online advertising and we’re ready to continue growing.

What You'll Do:

• You will build end-to-end full stack capabilities in our core platform across marketplaces like Amazon, Walmart, and Instacart. Amazon Ads is a $40B business today and every retailer on the planet is replicating the Amazon playbook. You will help us build deeper workflows into retail media platforms from across the globe

• You will contribute to system design and architecture across our back-end microservices primarily deployed on GCP. From how we ingest and process terabytes of data every day to how data flows through our systems to power our platform

• You will work closely with a team of 4-5 engineers, a product manager, and a designer to deliver a buttery smooth experience to our customers

• You will support the wider engineering organization by identifying areas of improvement, proposing RFCs, seeking feedback early and often, iterating over your ideas, and co-creating something better than you could have done by yourself


Who You Are:

• 5+ Years of software engineering experience in web-based technologies at a product company

• You have strong experience with Python frameworks such as Django/Flask, relational databases such as Postgres, and the cloud either GCP or AWS

• You have experience with modern JavaScript frameworks such as ReactJS. You consider yourself stronger in either front-end or back-end development, but at the same time, you are not afraid to go deep on the rest of the stack. You are comfortable with navigating a large codebase across dozens of repositories

• You’ve worked closely in teams of :5 engineers before, solving hard problems collaboratively, working tightly with your immediate peers as well as across teams

• Strong experience with algorithms, data structures, and complexity analysis

• You are comfortable navigating vague problems and creating clarity from uncertainty and communicating it clearly to your peers

• We believe in a culture of you build it, you ship it, and you wake up in the middle of the night to fix it. You have worked in an environment like that before and you loved it! You strive on iterating over complex problems until you’ve discovered simple solutions for them
