- • Design and implement low-latency, high-availability messaging solutions across unicast, multicast, and IPC transport paths
- • Tune and profile the full system stack—including CPU pinning, NUMA topology, kernel bypass, and receive buffer sizing—to minimize latency in production infrastructure
- • Build and extend Aeron Archive integrations for durable message replay and stream persistence
- • Design and implement solutions that mitigate risk, enforce security, and protect both systems and data
- • Write reusable, testable, and efficient C++ code for high-performance trading systems
- • Collaborate with cross-functional teams to contribute to product roadmap execution and technical decision-making
- • Work as part of a globally distributed team, leveraging strong communication skills to engage with stakeholders across time zones
- • Profile and optimize code using tools such as perf, flamegraphs, and VTune for CPU, memory, and network performance
- • Work with UDP networking, multicast, and kernel-bypass techniques such as DPDK or RDMA to enhance system throughput and reduce latency
- • Apply knowledge of lock-free data structures, mechanical sympathy, cache-line discipline, and busy-spin vs. park/wake tradeoffs in low-latency system design
- • Integrate and utilize Simple Binary Encoding (SBE) or similar zero-copy serialization formats for efficient data transmission
- • Maintain and enhance trading infrastructure components including matching engine, market data gateways, internal/external APIs, and margin systems
- • Apply deep understanding of Linux-based distributed and highly-concurrent systems in a high-volume transaction environment
- • Participate in code reviews, system architecture discussions, and incident response for critical trading systems
- • Stay aligned with Kraken’s mission to accelerate global crypto adoption through secure, high-performance infrastructure
🎯 Requirements

- • Deep understanding of low-latency systems fundamentals: lock-free data structures, mechanical sympathy, cache-line discipline, busy-spin vs. park/wake tradeoffs
- • Experience with Aeron or comparable messaging transports (e.g., Chronicle Queue, ZeroMQ, LMAX Disruptor)
- • Experience with UDP networking, multicast, and kernel-bypass techniques (e.g., DPDK, RDMA)
- • High level of proficiency in Python, Rust, and SQL
🏖️ Benefits
