Lucida AI

Full-stack Engineer

• 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
