Job description
We're hiring a Full-Stack Mobile Engineer to join Lucida AI.
This is a full-time, hybrid role for someone who wants to learn how a consumer AI product is built, shipped, and scaled from the inside.
You'll work across the stack — mostly in Flutter, but touching backend and infrastructure wherever the feature needs it — to help improve the experience of millions of language learners around the world.
This is not a passive internship.
We're looking for someone who can write clean code, ship fast, debug hard problems, ask good questions, and take ownership of features end to end.
Why join Backed by top-tier investors ($7M raised) Millions of users across global markets Small, high-performing team High ownership, fast decision-making, no bureaucracy Potential full-time opportunity after graduation Opportunity to help build a category-defining AI product Who you are Highly curious about AI, mobile apps, consumer products, and real-time voice experiences Comfortable building features in Flutter/Dart end to end — UI, state management, and API integration Understand how to work with REST/WebSocket APIs, async flows, and app architecture Care about performance, smooth UX, and shipping polished, bug-free builds Comfortable reading and touching backend code when a feature demands it Proactive, organized, detail-oriented, and comfortable following up Don't wait for step-by-step instructions; you look for ways to add value Comfortable working with data, logs, crash reports, and product metrics Communicate clearly in English Bonus if you have: published apps on the App Store / Play Store, experience with real-time audio, native platform code (iOS/Android), CI/CD, or backend work (Node, Python, Go, etc.
). What you'll work on Jump into the real codebase from day one, not shadow from the sidelines Build and ship features across the Flutter app — onboarding, lessons, roleplays, AI voice conversations, feedback flows, and monetization Work on real-time voice interactions and the flows that make them feel instant and natural Integrate with backend services and APIs, and dig into the backend yourself when needed Chase down bugs, crashes, and performance issues, and improve app stability Look at funnels, activation, feature usage, and paywalls to understand how your code affects real user behavior Test features before they go live, challenge weak UX, question unclear copy, and push for the details that make the product better Help ship fast, measure what happened, learn from the results, and move on to the next iteration Sometimes you'll work on mobile.
Sometimes on backend.
Sometimes on QA or performance.
Sometimes on things no one has a perfect job title for yet Important This role is designed for candidates who will graduate by June 2026 and will be ready to start working full-time after graduation.
If you are not graduating by June 2026, this may not be the right opening for you.
