Job Description

The InMobi Story We like big challenges. Building a new company in 2007 was no ordinary task. As the recession hit, the iPhone was born and launched a revolution. Mobile advertising wasn\'t yet a thing, other than SMS, and venture capital funding was hard to come by for four guys in India. Yet with passion, foresight, and conviction, InMobi charted its own course - helping to transform the way consumers engage with their phones and create today\'s booming app economy wherein consumers now spend 4.2 hours per day. After fourteen years of innovation, our end-to-end advertising software platform, connected content and commerce experiences have formed a powerful engine for growth that activates audiences, drives real connections, and diversifies revenue for companies around the world. Our global organization of InMobians are excited to continue discovering and developing impactful technologies that will continue to transform people, businesses, and society. About the team: There are 8 billion interactions a day by people with our recommendations. That\'s 5 million a minute! We see the success of our models and experiments astonishingly quickly. We live in what might be the fastest model-learning playgrounds in the world. We have built an infrastructure that enables model deployment at scale and speed. Our Machine Learning Engineers work closely with the rest of the data science and engineering teams to build models using the best-in-class AI tools and make the most of our large heterogenous data. This is a highly fertile environment for building, experimenting, refining and affecting real change from computational advertising models where the impact of our work becomes visible incredibly fast. The Experience You\'ll Need: To succeed in the Machine Learning Engineer role at InMobi, you will need a strong background in hands-on coding for training and deployment of ML/AI models and be capable of dealing with large scale data. You need to be well-versed with Deep Learning, and have a good understanding of modern DL techniques such as transformers, LLMs, etc. Required: Education: Bachelor\'s degree or higher in Computer Science, Engineering, Mathematics, or a related field. A Master\'s or Ph.D. in a relevant discipline is preferred. Experience: 6+ years of experience working as a Machine Learning Engineer or in a similar role. Demonstrated experience in designing, developing, and deploying machine learning models and algorithms. You should have created, stored, and retrieved embeddings in the most efficient manner, trained and deployed Deep Learning models, and run inference at scale. Strong programming skills: Proficiency in programming languages such as Python, Java, or C++. Experience with machine learning libraries and frameworks (e.g., TensorFlow, PyTorch, scikit-learn) is required. Familiarity with Microsoft Azure is a plus. Solid understanding of machine learning techniques: Strong theoretical and practical knowledge of machine learning algorithms, including supervised and unsupervised learning, deep learning, reinforcement learning, and natural language processing. Data handling and preprocessing: Experience with data wrangling, cleaning, and preprocessing techniques. Proficiency in PySpark and working with large datasets is desirable. Software engineering skills: Familiarity with software development practices and version control systems (e.g., Git). Ability to write clean, modular, and maintainable code. Problem-solving mindset: Strong analytical and problem-solving skills to tackle complex data-driven challenges.
