Do you have a passion for solving hard problems at scale? Are you eager to join a trust-based, globally-connected team, where your contributions will make a meaningful difference?

Come and see why Fortune Magazine consistently ranks The Trade Desk among best small-medium sized workplaces globally.


We are looking for an experienced Data Scientist to join our Solutions Architecture team.

  • You have a sustained track record of making significant, self-directed, and end-to-end contributions to applied mathematics, machine learning and data focused projects. You think beyond just the task at hand to deeply understand the 'why' behind what you are doing.

  • You are a broadly skilled data scientist who can apply various tools, data mining, statistical techniques, algorithms and machine learning principles to identify trends, patterns and insights from variety of data sources, and building models to address client’s business problems.

  • You can write code to perform data analysis and build models using common programming languages and embed them into production systems.

  • You are a problem solver. You have the passion and ability to articulate our clients’ unique needs and business goals. You help clients achieve them by formulating effective data driven advertising solutions.

  • You work with confidence and without ego. Our team members 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 people who know all the answers; we need people who can invent the answers no one has thought of yet, to the questions yet to be asked.


The Data Science Solutions Architect will design and build custom solutions that are powered primarily by applied mathematics and related advanced computation for our clients.

  • You will participate in all aspects of designing, mathematics researching, building, and delivering custom data science and data-focused products for our clients. You will work in wildly different areas of data science applications to include but not limited to game theory, numerical optimization, NLP, statistical and probabilistic modelling, linear/nonlinear programming optimization, partial differential equations, deep learning, and experimental causality

  • You will contribute to or lead projects of varying complexity and duration where you will communicate advanced mathematical concepts (and related implications) to both technical and non-technical clients, plan tasks, set timelines, manage and update stakeholders, resolve blockers and drive the process forward with other project team members.

  • You will monitor and manage custom solutions, debug application related issues causing solution outage or degradation, and implement necessary fixes.

  • You will help in building up our team through a combination of mentoring, technical leadership, making others better by raising the bar.

  • You will leverage background and experience to develop best practices that are scalable, repeatable and sharing these with the global Solutions Architect team


Skills and experience:

  • BA/BS in Mathematics, Operations Research, Statistics, Physics, Computer Science (AI/ML), Computer Engineering or a related field

  • Proven experience as a Data Scientist in solving business problems

  • Strong applied maths or machine learning skills for exploratory data analysis and design and development of models on big data sets (both streaming and batch).

  • 5+ years of experience in performing data analysis, data visualization, and creating models using a variety of programming languages (for example, Python, R, Java/Scala, etc.) and associated libraries/tools (such as pandas, scipy, matplot, Tableau, etc.)

  • Deep understanding and direct use of big data frameworks/platforms (Spark, Hadoop, etc.)

  • Experience in deploying predictive models and algorithms on one or more cloud services like EMR

Preferred (Not essential):

  • Experience working with REST APIs is a plus

  • Experience working with client, product, or engineering teams in a pre-sales role or consultative experience is a plus
