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
Collaborate with AI researchers to turn breakthrough concepts into working prototypes
Move fast: propose ideas, build, test, and refine based on real-world feedback
Solve performance issues before they become bottlenecks, ensuring everything runs at scale
Partner with cross-functional teams (AI, Product, Design) to create user experiences that truly matter
Experiment fearlessly: push boundaries, iterate quickly, and drive innovation forward
Talk to your Replika—hands-on usage keeps feedback loops short and insights fresh
Technical skills
Proven experience building large-scale iOS apps with complex user flows and high performance demands
Deep understanding of Swift (and SwiftUI is a plus), with an eye for architecture and concurrency
Comfortable with rapid prototyping—turning ideas into functional proofs of concept
Strong sense of ownership: spot issues early, jump in to fix them, and see features through from concept to release
Thrive in an environment of organized chaos—adapt quickly, embrace experimentation, and aim high
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
Opportunity to build an AI product that deeply impacts users
Expect to work some European hours, as the team is in Europe. Potential visa support is available
Global offsite meetings, including gatherings in San Francisco
