Join Bitcredit Protocol: Build the Future of Bitcoin Credit Money
About us
Bitcredit Protocol is a community-driven, open-source project dedicated to unblocking Bitcoin adoption. Our mission is to create a fiat-free financial system, empowering businesses and individuals by financing the working capital and wage fund needs so people can finally earn and spend in Bitcoin.
The project builds on freedom technology, including Bitcoin, Lightning, Cashu, and Nostr, to provide a censorship-resistant, trust-minimized, and scalable Bitcoin infrastructure.

Our Vienna lab is looking for experienced Rust Software Engineers for the backend effort. You’ll design, develop, and optimize high-load, mission-critical services that power future independent credit mint operators.
You’ll work on:
* Developing and refactoring high-performance Rust code for core backend services.
* Designing resilient, distributed systems for a trustless Bitcoin credit economy.
* Integrating with the Bitcoin ecosystem, including Mainchain, Lightning, and Cashu.
* Optimizing storage and data consistency using Nostr and CockroachDB.
* Collaborating with a high-caliber team of Bitcoin, Rust, and distributed systems experts.
* Delivering well-documented and tested code in a rigorous development environment.
We prefer full-time contributors, but exceptional part-time candidates will be considered.
