✨ What awaits you here:

We’re building the firmware powering Bitcoin mining worldwide, and right now we need a dedicated Full Stack developer to take full ownership of the Braiins OS interface. Our team is small, hands-on, and highly technical, focused on developing mining firmware—our most important product. You’ll make it accessible and maintainable while letting the rest of the team implement small UI changes safely themselves.

💪 Your Mission: Frontend First, Rust Later

• Take ownership of the frontend: build and maintain the Braiins OS UI using React, TypeScript, and the IBM Carbon Design System, ensuring our visual identity remains consistent.

• Build for the team: Set up a modular, AI-assisted environment that enables other engineers to implement features start-to-finish without deep frontend expertise, under your supervision.

• Collaborate broadly: Work with other teams on our ecosystem of tools and platforms to ensure a consistent experience.

• Grow into the backend: Once the frontend is stable, dive into Rust backends. You don’t need Rust experience, but curiosity and willingness to learn are key. Familiarity with similar languages (C/C++, Golang) is a plus.

🛠️ Tech & Tools You’ll Use

• Frontend: React, TypeScript, IBM Carbon Design System

• APIs: gRPC-Web, GraphQL

• Backend: Rust (learning supported)

• Development: Linux, Git, Nix, AI-assisted tooling

• Open to other technologies—we value simplicity and practicality over complexity

🔎 We are looking for someone:

• Passionate about technical challenges and learning new things

• Enjoy clean, simple solutions over complicated ones

• Hands-on and collaborative, able to guide others while owning your component

• Experienced with frontend development; willing to dive into backend Rust over time

🏖 What We Offer

• Real ownership: You’ll be the main owner of the Braiins OS frontend, with influence over architecture and tooling.

• Learn Rust: We’ll support you in mastering Rust, a top developer language.

• Team & Culture: Small, close-knit team in central Prague, flexible hours, good coffee, and honest communication.

• Stability: 5 weeks vacation, sick days, and long-term projects in Bitcoin mining.

• Flexibility: Full-time, Employee or Freelance options, indefinite agreement.

🔥 We will love you even more if…

• Experience with AI-assisted development tools

• Familiarity with microservices, TCP/UDP, or Linux systems

• Interest in cryptocurrencies or mining technology
