Sr. MLE, Responsible AI at Pinterest — bias mitigation and Gen AI safety across a 550M-user recommender platform
This role sits on Pinterest's Advanced Technologies Group, driving fairness, safety, and alignment work across Gen AI evaluation, foundation model fine-tuning, and Red Teaming that touches Search, Homefeed, and Content Understanding. It calls for 4+ years shipping large-scale ML-driven products plus at least a year leading cross-team engineering efforts, with a Master's or PhD expected. Strong fits can speak concretely to fairness interventions they've deployed at scale and to leading horizontal initiatives across engineering orgs.
