About the Role:

The Performance Automation team is dedicated to developing optimization tools that enhance our clients' advertising campaign outcomes, ensuring they meet or surpass their Key Performance Indicators (KPIs).

You will be working on enhancing machine learning model development; creating the tools and frameworks that allow for quicker iteration and refinement of models by data scientists, from creating ETLs that process petabytes of data to experimenting with novel model training architectures. You will be responsible for integrating models in our bidding infrastructure, where low latency and high performance are of paramount importance; your code will be running millions of times per second on datacenters across the entire globe.

You will be also working on developing and improving debugging and analytical tools for monitoring and adjusting the bidding system in real-time. Utilize these tools to quickly identify and address any issues, improving campaign efficiency and ensuring effective use of budgets and resources.

Our Software Engineer team members will participate actively in all aspects of designing, building, and delivering products for our clients.

We have dozens of mission-focused teams working across a wide spectrum of technological challenges. You will have the opportunity, depending on your interests and aptitude, to work on large-scale distributed systems coordinating thousands of servers in cloud and physical data centers around the world, petabyte-scale data challenges, machine learning, advanced visualizations, and interactive user interfaces – to name a few.

Trade Desk Software Engineers contribute to more than our product – they build up our team. Through a combination of mentoring, technical leadership, and/or direct management of small teams, they make others better and raise the bar for those around them.

Who We Are Looking For:

Skills and Experience

• 7+ years of demonstrated success in software development within high-scale enterprise environments.
• Hands-on experience with multiple platforms and technologies, including: PyTorch, Tensorflow, Spark, .NET Core, Java, SQL Server, Docker, Kubernetes, AWS, Azure
• Excellent understanding of Agile development methodology and development practices
• Understanding of designing Service-Oriented systems.
• Exposure to Machine Learning concepts and frameworks (a plus, but not required).
• Experience in building distributed systems and microservices.

Key Attributes

• You have a sustained track record of making significant, self-directed, and end-to-end contributions to large and impactful software projects. You think beyond just the task at hand to deeply understand the 'why' behind what you are doing.
• You understand engineering fundamentals. At our scale, many off-the-shelf techniques and existing technologies (open source and enterprise) simply don't work. You are able to work from first principles to evaluate solutions and adapt them to a unique environment.
• You are a broadly skilled engineer, accustomed to developing web services. You have experience building always-on systems, working across a variety of technologies and service layers.
• You have a product-focused mindset.  You have the passion and ability to contribute to the process of discovering what will delight our clients and push forward one of the world’s largest and most influential industries toward a vision of openness, transparency, and evidence-based decision-making.
• You work with confidence and without ego. Our engineers have deep knowledge and exercise a high degree of leadership in their daily work. You have strongly-held, defensible ideas, and advocate for what you believe is right. You are also adept at identifying and evaluating trade-offs, willing to be proven wrong, and quick to walk through fire to support your fellow teammates.
• You value, seek out, and foster diversity. We are a global team from many diverse backgrounds, with different experiences and perspectives. To complement this team, you will welcome ideas that are different from your own and be skilled at finding and building from common ground.
• You are a creative thinker, not bound by "the way things have always been done". 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.
• The position will be located in Boulder, CO and we do require Engineers to work under a hybrid office work attendance.
