About the role

Key responsibilities & impact

Develop and maintain core framework and key software components for the Kraken trading engine, with a focus on the Aeron-based messaging transport layer
Design and implement low-latency, high-availability messaging solutions across unicast, multicast, and IPC transport paths
Tune and profile the full system stack — CPU pinning, NUMA topology, kernel bypass, receive buffer sizing — to squeeze latency out of production infrastructure
Build and extend Aeron Archive integrations for durable message replay and stream persistence
Build and design solutions that mitigate risk, implement security, and protect both systems and data
Write reusable, testable, and efficient code
Collaborate with cross-functional teams and contribute to product roadmap accomplishment
Work collaboratively on a distributed team, leveraging soft skills to effectively communicate and engage with stakeholders

Requirements

What you’ll need

5+ years experience working with modern C++
Prior experience in at least one of the following using Linux — distributed and/or highly-concurrent systems; low-latency and/or high-volume transaction environments
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) highly desirable
Experience with UDP networking, multicast, and kernel-bypass techniques (e.g. DPDK, RDMA) a strong plus
Familiarity with SBE (Simple Binary Encoding) or similar zero-copy serialisation formats a plus
Experience profiling and optimising code (CPU, memory, network) — perf, flamegraphs, VTune, or equivalent
High level of proficiency in Python, Rust, and SQL strongly preferred
Demonstrated knowledge of order types, trading systems, and financial products is highly desirable
BS in a technical or quantitative field
