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.

Why Join Us?

• Work on the frontier of Bitcoin innovation—building a system that cuts out middlemen and makes Bitcoin usable in international trade and everyday transactions.
• Contribute to open-source finance—Bitcredit Protocol is built by the community, for the community. We open source everything.
• Join a passionate and mission-driven team—we’re here to make a real impact on how Bitcoin can work in a truly circular way.

About the Role

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.

Who You Are

Must-Have Skills

• Strong proficiency in Rust and its ecosystem.
• 4+ years of software engineering experience, with 2+ years in Rust production environments.
• Experience with distributed databases (e.g., CockroachDB, Cassandra).
• Familiarity with distributed stream-processing platforms (e.g., Kafka, Flink, Redpanda).
• Understanding of microservice architectures and scalable backend systems.
• Fluent English communication skills, both written and spoken.

Nice-to-Have Skills

• Understanding of the Bitcoin ecosystem.
• Familiarity with banking software and financial systems.
• Knowledge of e-cash protocols (e.g., Cashu, Fedimint).
