JOIN OLX SEARCH PLATFORM AI TEAM We’re on a mission to transform how millions of people discover and connect with what they need most - across Motors, Real Estate, Jobs, Services, and Goods. To achieve this, we’re building a new Search AI Platform that will power intelligent, personalized, and scalable search experiences across all OLX customer units. This initiative is sponsored directly by our CTO and represents a strategic leap for OLX: a new cross-functional team built from the ground up, bringing together machine learning engineers, data scientists, SREs, and platform engineers. Together, we’re redefining how search intelligence is built, shared, and scaled across our global ecosystem. As the Principal Search Machine Learning Engineer, you’ll be the technical guiding force behind this transformation. You’ll work alongside our Principal Search Engineer to shape the architecture, mentor the team, and deliver solutions that bring measurable business and user impact. You’ll have full ownership to explore, experiment, and push boundaries - from prototyping new search models to deploying them at scale. You'll also play a key role in growing OLX’s data science practice, mentoring peers, and shaping how AI is applied across the company. This is a hands-on leadership opportunity where you’ll see your ideas move from research to production and into the hands of millions of users.
