Now, we are entering the next stage.
As we expand our product portfolio, launch new AI-powered solutions, and build white-label products for institutions and partners, we are looking for an exceptional CTO / Technical Co-Founder to lead the technological future of LinqiApp.
Who We Are Looking For
We are not looking for a corporate executive. We are looking for a builder.
Someone who enjoys creating products from scratch, solving difficult technical challenges, making architectural decisions, and helping shape the future of the company.
As our CTO / Technical Co-Founder, you will work hand in hand with our existing Full-Stack Mobile Developer and Product Designer to transform ideas into world-class products.
This role combines:
- Technical leadership
- Software architecture
- Product development
- Team management
- AI innovation
- Infrastructure and scalability
If your mindset is “I only manage teams and attend meetings,” this role is probably not for you.
If your mindset is “I’ll design the architecture, jump into production issues when necessary, and help build a global company,” we’d love to talk.
Responsibilities:
- Define and execute the company’s long-term technology vision
- Lead technical decision-making across all products
- Own and evolve our TypeScript-based backend architecture
- Design scalable APIs and distributed systems
- Oversee integrations with third-party services and internal systems
- Lead the technical strategy for our Flutter-based mobile applications
- Support React Native and web-based initiatives where needed
- Design scalable multi-product and white-label architectures
- Ensure a high-quality user experience across all platforms
- Lead AWS infrastructure strategy and optimization
- Build scalable CI/CD pipelines
- Improve observability, monitoring, and incident management processes
- Drive automation across development and deployment workflows
- Lead integrations with LLMs and AI orchestration systems
- Build scalable real-time voice and multimedia systems
- Improve streaming, communication, and low-latency architectures
Qualifications & Preferred Tech Stack:
- 5+ years of experience in Software Engineering & Development
- Strong proficiency in TypeScript, Node.js, and modern backend architectures
- Experience building and maintaining REST APIs, WebSockets, and scalable distributed systems
- Hands-on experience with Flutter for cross-platform mobile development
- Solid understanding of AWS cloud services and cloud-native application design
- Familiarity with Docker, Kubernetes, GitOps, and modern CI/CD pipelines
- Experience designing microservices and scalable infrastructure
- Knowledge of AI/LLM integrations, including tools such as OpenAI or similar platforms
- Experience with real-time communication technologies such as WebRTC, audio streaming, or event-driven architectures
- Startup experience and an ownership mindset are strong pluses
Benefits:
- Founding-level equity. Equity only right now (no cash before we close funding); cash salary plus additional equity once funding closes
- Fully remote & flexible working hours (create anytime, anywhere)
- Real ownership in the company you help build
- Key person shaping the future of the company, product, and tech
- Work at a fast-growing EdTech startup
- High dedication, fast pace — we're racing to funding and market
🎯 You Are a Good Fit If
- You are a 100x engineer. Razor sharp. Able to solve difficult problems fast
- You have deep product sense. You build for users, not for code's sake
- You love mobile and care about clean, maintainable code
- You have experience building AI products, ideally mobile & web apps
- You are fascinated by the new coding paradigms. Claude Code, Cursor, coding agents. You're already using them
- You know how to scale yourself to an insane degree through automation
- You have great code taste and can review PRs at speed without sacrificing quality
- You are versatile. Backend-heavy but not allergic to frontend and design
- You thrive in ambiguity. You don't need a PM to tell you what to build
- You have built something from scratch before. A startup, a side project, a feature that shipped
- AI research background is a plus. Experience at an AI coding startup is a plus. But what matters most is that you're exceptional and hungry.
🚫 This role is not for you if
- You want well-defined requirements and rigid processes
- You avoid responsibility for production systems
- You prefer specialization over ownership
- You’re optimizing for comfort instead of impact
