About the team 

InMobi Commerce Cloud team is responsible for the retail media products that drive discovery, sales and profits on eCommerce properties. 

InMobi Commerce Cloud Group is investing heavily in building a world-class retail media advertising business. We are responsible for defining and delivering a collection of self-service advertising products that drive discovery and sales on eCommerce properties.  

Our products are strategically important to our retail media business delivering billions of ad impressions and millions of clicks across top retailer digital media properties. We are highly motivated, collaborative, and fun-loving with an entrepreneurial spirit and bias for action. With a broad mandate to experiment and innovate, we are growing at an unprecedented rate with an endless range of new opportunities. 

The Role 

In InMobi Commerce Cloud, we are applying Machine Learning at a massive scale to optimize retail media advertising performance. We are looking for talented Data Scientists with 3+ years of experience to work on cutting edge machine learning challenges & problems in artificial intelligence for retail media domain. The challenge entails research, prototyping, and experimentation with state-of-the-art ML techniques. You will work together in a team of Data Scientists, Software and Data Engineers, Product Managers and Business Development Leaders. 

You will be working on cutting edge retail media advertising use cases such as Bid Price Forecasting, CTR prediction, CTR\CVR optimisation, Ad selection and Campaign performance etc to help increase revenue for advertisers and retailers. You will build the next generation of machine learning models and optimization algorithms that power the real-time smart bidding platform in a fast-paced environment. 

You will research the latest advances in ML prediction and forecasting techniques, construct prototypes to validate your hypothesis, work with engineers to turn these prototypes into production systems and perform offline analysis and online A/B experimentation. 

You will be encouraged to attend workshops and conferences (internal and external), with opportunities to write papers, participate in science events, and obtain early access to ML technologies from our industry partners.

  • You have at least 3+ years of work experience in domains such as computational advertising, web search, recommendations, and personalization 
  • You have hands-on experience implementing production machine learning systems at scale in Python, Scala, Java or similar languages.  
  • Industry experience with frameworks such as Tensorflow and the Tensorflow ecosystem (TFX) is also a plus. 
  • You have experience with data pipeline tools like Apache Beam, Spark, etc., and cloud platforms like GCP or AWS. 
  • Experience handling planet-scale datasets 

Other skills:

  • Outcome-obsessed, pragmatic scientist who is relentlessly focused on creating positive business impact 
  • Strong analytical, quantitative problem solving, and communication skills 
  • You can bridge the gap between research and real world problems, and have great judgement and intuition on which approach will work well in practice 
  • You excel in communicating complex ML techniques and scientific concepts in an easy-to-understand way 
  • You are a team player and you thrive in a collaborative environment 
  • You thrive in a fast-paced environment. You are comfortable getting started with minimal information and can bring clarity via rapid iterations 

 Preferred Qualifications 

  • Experience working with advertising, retail, financial, or e-commerce data.  
  • You’re experienced with traditional as well as modern machine learning/statistical techniques, including Regression, Classification, Ensemble Methods, Deep Learning and Reinforcement Learning. 
  • Experience using Deep Learning, Bandits, Probabilistic Graphical Models, or Reinforcement Learning in real applications 
  • At least 3+ years of experience in optimizing business metrics through automated algorithms (real-time bidder, recommendation engines, information retrieval, pricing etc.) 
  • Experience in auction theory, game theory, with a strong background in statistical methodology and/or big data. 
  • Experience in advanced machine learning topics like Privacy, Fairness, Meta-Learning, Active Learning, Reinforcement Learning, Federated Learning, etc.
