About the role

As a Staff ML Researcher you will work on challenging ML projects that extend and improve the way ML is used in our company. ML is at the very center of RTB House, and you will have a strong, immediate impact on our core metrics. We are looking for a strong individual contributor who will lead research projects of high scope and ambiguity. The following skills will be crucial:

Ability to solve unclear problems. You will have to understand the core of the issue, define the goal and how to measure success, and find the most effective way to solve the problem.
Hands-on ML expertise. This is an applied research role: we build ML systems that run in production. You will write code, train models, run experiments, and ship — the measure of success is real-world impact.
Being results oriented. We value a healthy drive to solve problems effectively, by starting simple and using complex tools only when necessary, always striving for a simple, elegant solution.
Leadership skills. We're looking for someone who can identify high-potential projects, create a vision, communicate with stakeholders, and above all, execute.
End to end ownership. You will own the projects from conception, through analysis, research, building a proof of concept, testing, to final implementation and deployment.
Effective communication. In this role you will collaborate with many people, and it's crucial to communicate well and organize the work effectively.

You Will:

Identify, define, and drive research projects with company-wide scope and direct impact on our core metrics.
Design and implement models, most often deep neural networks, used to predict the behavior and preferences of Internet users.
Develop and test new approaches to modeling key issues, such as bidding in first-price auctions.
Conduct and analyze A/B tests of new solutions.
Follow and analyze the latest works in the field of Machine Learning, and translate them into practical improvements.
Mentor researchers and shape research practices across teams.

Selected technologies used:

Python, Java, Scala
PyTorch, NumPy, Pandas
TPU, JAX
Jupyter Notebooks
BigQuery, GCP

Expected experience

5+ years of experience as researcher or engineer.
2+ years of hands-on experience with Machine Learning / Data Science.
Proficiency in programming.
Sound mathematical knowledge and intuitions.

Nice to have

Strong theoretical mathematics framework: statistics, probability, discrete mathematics, combinatorics.
Experience in AdTech is a plus, but not required.

What we offer

Attractive compensation
Technology: access to the latest technologies and real opportunity to use of them in large-scale and highly dynamic projects; working on extensive and rich datasets.
Impact: your work will be immediately impacting the company's business results and outcomes globally as well as mentor less experienced colleagues in the team.
Wellbeing: remote and on-site work possible. Flexible working hours.
Culture: work in a team of enthusiasts with wide experience in ML who willingly share their knowledge and learnings on a daily basis, no BS environment.
Purpose-Driven Work: being at heart of the system, your growing knowledge and competences will be used in practical applications directly connected to business results.
