Reporting to the Chief Data Officer at OLX, you will be responsible for leading and supporting the engineering roles responsible for building capabilities to allow our users to improve user experience with the application of Generative AI.
This transformation is strategic, as it will unlock new experiences on our existing products across our categories (horizontals and verticals) spanning many diverse customer journeys. In the next few years, we expect GenAI will likely transform the way users are buying and selling things across our platforms. OLX is already applying Generative AI to an increasing number of product areas, to simplify the posting flow, rethink the buying experience (evolving from filters to intent-based buying) and enable frictionless, inspiring, and trusted interaction across categories and user segments.
You will have the responsibility to co-lead the product development teams together with the respective Directors of Product, form a technology strategy and architecture vision, as well as the day-to-day delivery of your teams, supporting and enhancing the OLX engineering culture, growing the team and its capabilities and working with your peers to ensure business success.
You will need to partner closely with peers in Data and Design, as we expect to influence our product direction driven by technology trends and innovation. You will work closely with other engineering leads and stakeholders supporting the scale of many capabilities and products. You will be responsible for both large step-change product innovation and continued, high-velocity incremental feature development, helping deliver value to our customers that they happily pay for seamlessly.
Your experience should include leading a relevant, sizable engineering organization within a hyper growth environment - strong leadership skills evidenced by an ability to inspire engineering teams through clear communication and technical excellence. You will need to be up to date with current technologies and tools and feel comfortable with making difficult technical decisions to improve major aspects of our solutions and the user experience.
