Roles & Responsibilities

Experienced frontend development with React and TypeScript
Ability to guide others while owning your component, hands-on and collaborative
Passionate about technical challenges and learning new things
Willing to explore backend Rust over time (familiarity with C/C++, Golang a plus)

Requirements:

Take ownership of the Braiins OS frontend, building and maintaining the UI using React, TypeScript, and the IBM Carbon Design System while preserving visual identity
Set up a modular, AI-assisted environment enabling other engineers to implement features start-to-finish under your supervision
Collaborate with other teams to ensure a consistent experience across the ecosystem of tools and platforms
Grow into the backend by learning Rust and contributing to Rust backends as frontend stabilizes

Job description

✨ 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…
