Job description

Proof of work

The team

Our Platform and Core Engineering teams build the systems that make Kraken secure, resilient, and scalable. Their impact isn’t measured by customer-facing features, but by the strength, correctness, and leverage of the foundations they create. These teams power Kraken systems behind the scenes — enabling product teams to move fast while meeting the highest standards for reliability, compliance, and security. Engineers design shared services, internal platforms, and critical infrastructure that support company-wide initiatives. They optimize for safety, scalability, observability, auditability, and operational excellence — often operating in regulated, security-sensitive, and risk-heavy environments where precision matters. We’re looking for engineers with deep systems ownership and an architecture-first mindset — builders who take pride in long-lived services, thrive in complex environments, and are motivated by strengthening the backbone of the crypto ecosystem.

The opportunity

• Design and implement robust Rust services and foundational libraries that power Kraken’s core infrastructure, prioritizing correctness, security, and long-term maintainability.
• Write reusable, testable, and highly efficient code built for scale, observability, and operational resilience in production environments.
• Collaborate on large-scale distributed systems architecture, shaping low-latency, fault-tolerant services that support global trading and internal platforms.
• Work alongside hundreds of experienced Rust engineers, contributing to a high-bar engineering culture grounded in ownership, rigor, and craftsmanship.
