To complement this team, you will welcome ideas that are different from your own and be skilled at finding and building from common ground. ## Description Our Senior Identity Engineers are end-to-end owners of the systems they build. You will design, build, and operate large-scale distributed systems and data products that process petabyte-scale data across cloud and physical infrastructure. You will collaborate closely with data scientists, platform engineers, and product teams to deliver reliable, high-performance systems that serve clients at global scale. What We Build At the core of our platform is a sophisticated identity infrastructure that powers how we understand and connect audiences at scale. We build systems that construct and maintain large-scale identity graphs - linking signals across devices, channels, and environments in a privacy-conscious way. We develop frameworks to continuously evaluate identity graph performance, measuring accuracy, coverage, and quality so our systems improve over time. This work sits at the intersection of data engineering, distributed systems, and data science/ML, and directly shapes how the open internet operates for advertisers and publishers worldwide., Variety of technical opportunity is one of the best things about working at The Trade Desk as a software engineer which is why we do not expect you to know every technology we use when you start. What we care about is that you can learn quickly and find solutions to complex problems using the optimum tools for the job.What you know is less important than how well you learn and innovate. We don't need engineers who know all the answers; we need engineers who can invent the answers no one has thought of yet, to the questions yet to be asked. ## Related Videos - [Alibaba Big Data and Machine Learning Technology](https://www.wearedevelopers.com/videos/37-alibaba-big-data-and-machine-learning-technology) - [Modern Data Architectures need Software Engineering](https://www.wearedevelopers.com/videos/1030-modern-data-architectures-need-software-engineering) - [Docker Compose: Rediscovered](https://www.wearedevelopers.com/videos/1978-docker-compose-rediscovered) - [Swapping a Data Warehouse at Runtime: Zero-Downtime Migration Without Changing a Single Client](https://www.wearedevelopers.com/videos/100311-swapping-a-data-warehouse-at-runtime-zero-downtime-migration-without-changing-a-single-client) - [PySpark - Combining Machine Learning & Big Data](https://www.wearedevelopers.com/videos/44-pyspark-combining-machine-learning-big-data) - [Docker build without Docker](https://www.wearedevelopers.com/videos/100114-docker-build-without-docker) ## Related Articles - [Dev Digest 120 - Apple and peers](https://www.wearedevelopers.com/magazine/455-dev-digest-120-apple-and-peers) - [Where To Find Software Engineering Jobs](https://www.wearedevelopers.com/magazine/396-where-to-find-software-engineering-jobs) - [Dev Digest 121 - AI goes offline](https://www.wearedevelopers.com/magazine/456-dev-digest-121-ai-goes-offline) - [Navigating the AI Shift](https://www.wearedevelopers.com/magazine/629-navigating-the-ai-shift) - [Highest Paying Tech Companies for Developers](https://www.wearedevelopers.com/magazine/220-highest-paying-tech-companies-for-developers) - [WeAreDevelopers Dev Digest Issue 116 - The new search wars…](https://www.wearedevelopers.com/magazine/445-wearedevelopers-dev-digest-issue-116-the-new-search-wars)
