Recognized by TIME as one of 2025’s Best Inventions and by Inc. for Best in Business for Innovation, Pindrop is backed by leading investors including Andreessen Horowitz, IVP, and CapitalG. We are looking for Research Scientist Interns to help explore exciting research ideas across one or more of the following areas: fraud detection, authentication, speech and audio processing, video analysis, biometrics, and synthetic media detection. This candidate will work in a world-class team of researchers and will play a key role in developing next-generation technologies that improve trust, security, and user experience across voice and digital interactions. You are a creative problem solver who is excited about building amazing products that add real value to millions of people. You are enthusiastic about biometric security, fraud prevention, authentication, and developing research ideas into products. You can explain complex topics in simple terms, and you love building strong relationships with colleagues and stakeholders. You are a self-starter and excel in a fast-paced, dynamic environment that often includes ambiguity. You are resilient in the face of challenges, change, and ambiguity. You are optimistic and believe that you can make a problem into a solution. You are resourceful, excited to uncover innovative solutions, and teach yourself something new when needed. You take accountability, do the things you say you will do, under-promise and over-deliver. You are nimble and adaptable when priorities change and continue to see the forest through the trees.
