Who you are:
Our culture is much deeper than just having fun together (though we do that well, too). We take pride in our engineers being trust-builders, generous givers, scrappy problem solvers, and gritty pursuers of excellence. You do not have to meet all the requirements below, but we believe that people who meet most of them will have a higher likelihood of succeeding in this role:

• 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 have experiences working with distributed systems.
• You are proficient in one or more of the following programming languages: C#, Java, C, C++, Python, SQL, or Scala.
• You have some knowledge of software development code editors: Visual Studio, Visual Studio Code, Rider, and version control systems (Git, Perforce).
• You have 7+ 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: database engines (Microsoft SQL Server, Postgres, Aerospike, Vertica, Redis), building micro-services, operating systems and cloud, Kubernetes, Kafka.

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.
