Rust Engineer - Financial Infrastructure

About CloudWalk:

At 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. With millions of customers and a hunger for innovation, we are redefining what financial infrastructure can do.

About the Team:

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.

About the Role:

As a Rust Engineer in Financial Infrastructure, you will design, build, and maintain high-performance systems that power credit, investments, and regulatory compliance. You will work with Rust, PostgreSQL, and modern cloud infrastructure to deliver reliable, auditable, and scalable software for the financial core of CloudWalk.

What You'll Do

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

What You Need to Succeed

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

Join us at CloudWalk, where we're not just engineering solutions; we're building a smarter, AI-driven future for payments and credit—together.
