Rust Jobs for Rustaceans

About CloudWalk
We are building Brazil’s first self-driving bank: a financial institution that operates autonomously, with decisions powered by data and systems designed to work seamlessly for the customer.

Our team is responsible for developing the financial infrastructure that makes this possible. We build and operate systems for the full lifecycle management of CDBs, integration with CETIP/B3, regulatory data systems for the Central Bank of Brazil, accounting, and blockchain integration.

This is a high-responsibility environment where precision and security are non-negotiable.

Key Responsibilities:

• Develop and maintain Rust-based features across credit, investments, and regulatory compliance domains
• Write SQL queries in PostgreSQL
• Contribute to unit and integration tests, helping maintain code quality and coverage
• Work closely with the team on code reviews, architecture discussions, and technical documentation
• Investigate and fix bugs in critical production flows

Requirements:

• Experience with, or strong interest in, statically typed programming languages, especially Rust
• Solid understanding of databases and SQL
• Ability to read and understand other people’s code, not just write your own
• Strong attention to detail and a careful mindset, especially in environments where mistakes have real financial impact

Nice to Have:

• Experience with Rust
• Background in financial systems, fintech, or regulation (BACEN, CVM, CETIP/B3)
• Familiarity with Kafka, Redis, or messaging systems
• Experience with observability tools such as tracing, metrics, Prometheus, or Sentry
• Experience with Kubernetes or cloud environments, especially GCP

We may use artificial intelligence (AI) tools to support parts of the hiring process, such as reviewing applications, analyzing resumes, or assessing responses and identifying potential inconsistencies or verification signals in application materials based on available information. These tools assist our recruitment team but do not replace human judgment. Final hiring decisions are ultimately made by humans.
