Why Cashier Team?

The intersection of payments, loyalty, and blockchain is moving fast, and we are building at the absolute frontier. At Cashier Team, we're creating the core infrastructure for next-generation rewards and user engagement, giving businesses power without forcing them to deal with complex engineering integrations.

We aren't looking to hire people just to complete Jira tickets. We want builders who crave autonomy. If you want to own critical architecture, build cutting-edge Web3 systems in Rust, and have the freedom to drive real product impact from day one, this is your launchpad.

What You Will Build & Own

• Core Microservices & Logic: Architect modular, flexible backend systems in Rust and write immutable smart contract canisters on the Internet Computer (ICP).
• State & System Design: Build deterministic, fault-tolerant state machines for core flows, pairing type-safe Rust logic with our Svelte + TypeScript frontend.
• Cross-Chain Integrations: Contribute to future work connecting our platform with Bitcoin, Ethereum, and Solana networks.
• Technical Standards: Set high standards for clean code, write elegant APIs, and design intentional architecture where every system boundary and trade-off is deliberate.
• Ecosystem Connection: Engage directly with global Web3 developer communities (including Dfinity) to adopt emerging standards in NFTs, DID, and cycle management.

Who You Are

• Proven Rust Experience: Direct professional experience writing, deploying, and maintaining backend systems in Rust.
• Architectural Mindset: Appreciates clean system design, state machines, and building modular codebases for immutable smart contracts.
• High-Agency Builder: You don't need line-by-line instructions. You understand product goals, ask the right questions, and build reliable solutions end-to-end.
• Web3 Curiosity: Foundational knowledge of smart contracts and decentralized protocols (direct ICP experience is a bonus, but strong adaptability matters most).
• Clear Communication: Comfortable collaborating in English (written and spoken) with a remote, builder-first team.

What We Offer

• Direct Ownership & Impact: We start with high trust by default, combined with a low-micromanagement and low-meeting environment designed for deep focus. You'll have the ownership to drive features and architecture end-to-end, with the shared responsibility to keep systems reliable.
• Frontier Tech Stack: Hands-on experience building low-latency decentralized infrastructure on next-gen Web3 tools.
