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

• Own key parts of the iOS experience, architecting and fine-tuning features that keep users coming back daily
• Boost performance and reliability, eliminating bottlenecks and making sure everything runs flawlessly
• Work closely with AI, Design, Product, and every other team to transform innovative ideas into user experiences that truly matter
• Move fast : propose ideas, build, test, and refine based on real-world feedback
• 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

• 4+ years of experience building large-scale iOS apps with complex user flows and high-performance demands.
• Deep understanding of Swift, strong knowledge of SwiftUI and Concurrency, plus familiarity with reactive programming, Objective-C, and Realm.
• Proficiency in working with diverse libraries and frameworks, with the ability to adapt to different functional and non-functional requirements.
• 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.
