About Replika

Replika is an AI companion loved by 40M+ users around the world. We’re redefining what it means to connect with technology- emotionally, intelligently, and personally. From mobile to VR, we’re building an experience that feels less like software and more like someone who gets you.

We’ve been featured in TED Talks, Stanford and Harvard studies, the Lex Fridman podcast. All for one reason: people connect with Replika in a deeply human way.

We're scaling fast and taking on bold challenges to become the most human AI on the planet.

Despite our global reach and ambitious goals, we are not a large organization. We operate as a fast, lean startup, fueled by a small, tight-knit team of highly experienced engineers. This is an environment where you can make a real impact, and we want you to be a part of it.

About the role

We’re looking for an iOS Engineer to design and scale the systems powering Replika’s emotional AI. 

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

What We’re Looking For

• Experience building large-scale iOS apps with complex user flows and high performance demands.
• Deep understanding of Swift, strong knowledge of SwiftUI and Swift 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 different time zones
• This is a contract position, with potential to convert into a long-term engagement

Why Join Us?

• Competitive salary.
• Flexible job schedule and generous vacation policy.
• Unlimited access to the latest AI coding assistants.
