Job description

The Trade Desk is a global technology company and the world’s leading independent platform for digital advertising, with nearly 4,000 employees across more than 30 offices. Our technology helps advertisers reach the right audiences across the open internet — from streaming TV and podcasts to mobile apps, news, and more. Advertising powers the content people love. By making it more transparent, effective, and responsible, we help support trusted journalism, quality entertainment, and creators worldwide. The world’s brands and agencies rely on us to reach their customers and grow their businesses responsibly. The scale of our platform brings unique technical challenges — from processing massive datasets in real time to building systems that operate reliably on a global scale. When you work here, your impact is worldwide. We welcome diverse perspectives, encourage curiosity, and build teams that learn from one another. If you’re driven to solve meaningful challenges, we’d love to meet you.

What we do

Our Software Engineers are end-to-end owners who have the opportunity to participate in many aspects of designing, building, and delivering data-focused products for our stakeholders. At The Trade Desk, we believe that each opportunity to engage with consumers is unique. User experience can make or break our business. This means our users must have all the flexibility to harness our system’s growing power and present meaningful insight from the petabytes of data streaming through our platform with unparalleled ease. Our system performs every day, 24/7, serving global traffic. We deliver features to improve our clients’ abilities to make real‑time decisions and troubleshoot campaigns with simple-to‑use interfaces and high-performance data interactions. To improve our users’ day‑to‑day lives, we collaborate closely with user experience and product management organizations to ensure consistent, modern designs as well as the right balance of requirements. Our frontend developers work up and down the stack (client to server) to deliver these world‑class experiences.

What you’ll do

• Design, build, deliver, and own full lifecycle development software from inception to production
• Collaborate with team members to deliver features
• Implement and maintain product features
• Validate changes to ensure high quality product releases
• Work in a distributed system environment
• Understand the business objectives behind the code
• Understand system architecture fundamentals through self‑directed learning

We are a global team with different backgrounds, experiences, and perspectives. To complement this team, you will welcome ideas that are different from your own and be well‑versed in building from common ground to value, seek out, and foster invisible and visible dimensions of diversity.

Who you are

• You are comfortable working on an agile, distributed team spanning multiple time zones and continents.
• You are able to communicate effectively across both technical and non‑technical audiences.
• You have a solid understanding of computer science and engineering fundamentals.
• You are passionate about building beautiful and seamless user interfaces.
• You have love for, and desire to advance, the state of the artof technology.
• You are trained in JavaScript/TypeScript.
• You have 2+ years of software development engineering experience.
• You have a Bachelor’s/Master’s level degree in computer science or relevant engineering‑related field or equivalent experience. Not everyone has the same level of access to opportunities. What is most important to us is what and how you can contribute, which is why our consideration is not limited by the level of education you have.
• You have additional nice‑to‑have experience in the following areas: languages/technology on the server‑side (C#, Java, NodeJS, SQL), building enterprise level services or web‑based user experiences, knowledge of front‑end frameworks (React/Redux).

A variety of technical opportunities 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 are not seeking engineers who know all the answers; we need engineers who can invent answers no one has thought of yet and find answers to the questions yet to be asked.
