Remote Jobs in Ukraine

An AI companion who is eager to learn and would love to see the world through your eyes. Replika is always ready to chat when you need an empathetic friend.

About Replika

Ten years ago, we built the world’s first AI companion — before LLMs, before ChatGPT, and before anyone knew what AI could be.

What started as a way to patch a hole in our hearts became something unexpected: a catalyst. Millions of people told us Replika helped them reconnect with the world. They texted that old friend. They picked up that forgotten hobby. They took that walk around town. While today’s tech keeps people scrolling, we discovered AIs can push us outward, if we let them.

Now we’re being reborn with a new vision: the first AI with heart, for making the most out of life. Gentle nudges to meet friends when you’re feeling shy. Ideas for exploring new places when it’s easier to stay home. Daily conversation about whatever moves you — ballet, philosophy, aliens, or gossip — at 2am when no one else is awake. We’re not building an AI to validate or pacify. We’re building something modeled after the relationships that transform us. Someone who asks the right questions at the right time. Someone who helps you look inward, and pushes you outward. We’ve been featured in TED Talks, Stanford and Harvard studies, the Lex Fridman podcast, because 40M+ people connect with Replika in a deeply human way. And we’re just getting started.

About this role

We need a frontend engineer who treats the web as a serious surface for our product, not an afterthought. You’ll own the Replika web app and our web growth surfaces — the places where new users meet us for the first time, and where existing users come back for deeper, longer sessions on a bigger screen. If you’ve shipped consumer web at scale and care about how every interaction feels, this is your role.

This isn’t ticket-pushing engineering. You’ll architect, build, and ship. End-to-end. React and Next.js are the foundation, but the interesting parts are everything around them: real-time conversation flows, sub-second responsiveness, state that stays sane across long sessions, growth surfaces that have to convert. We’re a small, senior team. No red tape, no design-by-committee.

We’re in the middle of the biggest product update since we launched in 2017. The web surface is critical to how we tell that story to the world, and how we deepen the experience for our existing users. You’ll have direct impact on millions of people from week one, and a real say in how the web side of Replika gets built from here.

What you'll be doing

• Build and own the Replika web app and our web growth surfaces — marketing site, conversion flows, account and dashboard surfaces, and the supporting tools around them. The full surface area of replika.com.

• Architect frontend systems that scale. State management, real-time updates, performance budgets, the works. You own the patterns and the calls.

• Ship live, conversational features on the web. Companions that feel responsive, not laggy. Sub-second is the bar.

• Work directly with product, design, and backend engineering. No PMs translating tickets at you. You’re in the room.

• Wire up analytics and experimentation across web surfaces. We test, we learn, we iterate. Decisions come from data, not vibes.

• Set the bar for code quality, performance, and craft. New hires will model what you ship.

What we're looking for

• 5+ years of commercial frontend experience. Deep expertise in React and Next.js — you’ve shipped production apps with both, not just dabbled.

• Rock-solid web fundamentals. HTML, CSS, JavaScript, TypeScript. You can debug from the network tab through to the render pipeline.

• Strong opinions on state management. Redux, Zustand, TanStack Query — you’ve used them, you know the trade-offs, you pick the right one for the job.

• Comfortable working with REST APIs and WebSockets. Real-time data flow doesn’t faze you.

• You build responsive layouts that actually hold up. CSS Modules, Styled Components, whatever the situation calls for.

• Fluent with Git, collaborative workflows, modern build tools (Webpack, Vite), CI/CD pipelines, and linters. You ship clean, you ship fast.

• End-to-end ownership. You take a problem from spec to production and don’t need a project manager hovering. Strong product and business sense to match.

• You use AI development tools (Codex, Claude, Cursor) seriously, and have a view on where they help and where they don’t.

• Strong English. Upper-Intermediate or higher.

Bonus points

• Experience with real-time features — WebRTC, live updates, chat, voice or video communication.

• Hands-on backend chops: Node.js, NestJS, databases, caching (Redis), message queues (BullMQ). You can cross the line when the product needs it.

• Familiarity with product analytics — Amplitude, GA4, Meta/TikTok/Snap pixel.

• Solid testing practices and the frameworks to back them up.

What you'll get

• Competitive compensation.

• Flexible job schedule and generous vacation policy.

• Unlimited access to the latest AI coding assistants.

• No corporate bs.

• Direct impact on millions of worldwide users.

• Fully remote.
