Opportunity to work on globally used web and developer platforms Direct impact on frontend architecture, APIs, and developer-facing solutions Collaboration with international , cross-functional engineering and product teams Work on large-scale mapping and location-based technologies used worldwide Project You will join a mature, large-scale production search project combining traditional lexical search technologies (Solr/Lucene) with semantic search and machine learning-based ranking. The project focuses on improving search relevance and ranking quality through rigorous statistical analysis, causal inference, and experimentation. You will work closely with search and ML engineering teams, designing experiments, analysing user behaviour, identifying biases, and evaluating the impact of ranking changes on production metrics.
