About Replika

Replika is hands down one of the most exciting forces in AI and tech today. Think: 4,000+ feature articles in the past year, TED Talks with our founder, studies from Stanford and Harvard, Lex Fridman podcast inclusion, and a Quartz founder story. We’re the only empathetic AI out there, making sure all 35M+ users feel seen, heard, and understood—whatever that means for them. So yes, we’re a bit like a future Samantha from Her, but even more powerful and in the palm of your hand. And most importantly, Replika cares for you.
Since 2016, we’ve been redefining conversational AI across iOS, Android, web, and VR. Our AI companions take many forms—holograms, AR/VR avatars, even robots. The ultimate AI life assistant, mentor, therapist, friend. Whatever you need, really, Replika is there for you. Right now, we’re rebranding with one of the world’s top design agencies, scaling our global team, and pushing human-AI connection further than ever. We’re the humanists in AI. And we’re making sure it’s done right.

What you’ll do

Lead the design, development, and optimization of experimental iOS features

Strong sense of ownership: spot issues early, jump in to fix them, and see features through from concept to release

Fluent in English (B2+), because we’re a global team working across time zones

What we offer

Competitive salary based on your experience and skill set
