To learn more, visit www.inmobi.com Overview of the role: We are looking for a Staff Applied Scientist I to join our algorithmic and research science team. Youâll work on mathematically rigorous, research-driven problems at production scale, while also shaping the direction of key initiatives and mentoring other scientists. This role sits at the intersection of theory and application, designing algorithms that combine elegant modeling with measurable business impact. Specifically, our scientists tackle challenges across traffic shaping, fraud detection, ad quality, pricing strategies, and auction theory, along with their practical applications. We leverage the latest deep learning models alongside classical machine learning techniques to build innovative solutions. As the heart of the InMobi Exchange, our team optimizes the companyâs core business functions and creates the strategic moat that sets us apart in the market. As a Staff Scientist, you will not just âuse modelsââyou will formulate them, evaluate their assumptions, tailor them to our problem domain, and bring them to life in productionâwhile providing thought leadership to the broader team. Many of our challenges have no off-the-shelf solutions; we require scientific creativity to bridge research and reality. If you thrive on solving complex, high-impact problems and want to see your ideas shape the future of a global exchange, this is the place where your work will truly make a difference.
The impact you'll make:
Formulate, analyze, and implement algorithms that power real-time auctions, dynamic pricing, bid shaping, pacing, and traffic allocation across a massive-scale ad marketplace.
Design and experiment with methods in online learning, reinforcement learning, multi-armed bandits, forecasting, game theory, and Bayesian modelingâin non-stationary, adversarial environments.
Collaborate with product and engineering teams to deploy your models in production and run real-world experiments with rapid feedback loops (measured in hours, not weeks).
Provide technical leadership by reviewing scientific approaches, mentoring junior scientists, and guiding the team toward robust methodologies.
Contribute to the scientific community by publishing high-quality research, conducting internal seminars, and staying abreast of advances in machine learning, algorithms, and applied statistics.
Evaluate the long-term dynamics of deployed algorithms, incorporating feedback, exploitation-exploration trade-offs, and incentives within multi-agent systems.
Identify new areas for innovation by translating business challenges into research questions and proposing novel, high-impact methodologies.
Translate mathematical ideas into practical, high-performance algorithms that operate at scale in production environments.
Explore and close the loop between model predictions and real-world outcomes, refining algorithms based on system behavior.
The experience we need:
Ph.D. (preferred) or Masterâs degree in Computer Science, Statistics, Mathematics, Operations Research, Physics, or a related quantitative discipline.
7â10 years of experience working on algorithmic or applied research problems, including significant production deployment experience.
Deep grounding in one or more of:
Statistical learning theory, mathematical optimization, discrete algorithms, probability theory, and information theory
Causal inference, decision theory, game theory, auction theory
Online learning, bandits, RL, Bayesian methods
Strong publication record (e.g., NeurIPS, ICML, AISTATS, KDD, UAI, WSDM, EC, SODA, COLT) is a strong plusâeven if not recent.
Proficient in scientific computing with Python, including packages such as NumPy, SciPy, PyTorch, or TensorFlow.
Comfortable working with big data platforms like Apache Spark, distributed computing, and large-scale datasets.
A researcherâs mindset: questions first, implementation later. You are thoughtful about assumptions and rigorous about validation.
End-to-end ownership: you can go from idea to production and thrive in applied settings.
Prior experience in ad tech, marketplaces, or dynamic pricing is helpful but not required.
