Before you apply, we encourage you to explore our culture page to understand what drives us and how we work.

The team

Founded in 2011, Kraken is one of the world's longest-standing crypto platforms, trusted by over 10 million individuals and institutions across the globe. It offers spot trading, margin, futures, staking, and OTC services, with products built for both individual investors and institutional clients.

The Exchange team is responsible for everything to do with the trading backend services such as the matching engine, market data gateways, internal and external APIs, margin systems and various other trading services. The team is located globally and responsibilities are split into sub-teams, working with various tech stacks. Our teams code in C++, Go, Rust, and Python, depending on the product they are contributing to within Kraken and work agile around the globe. Recently, the Trading Technologies team played a critical role in scaling Kraken's trading infrastructure.

• Champion performance and market data work as top priorities, while also supporting the team's broader technical scope

• Bring AI-assisted engineering practices into the team's workflow and help engineers adopt them

• Partner cross-functionally with product and other engineering pods to drive roadmap execution

• Represent the team technically with peer teams and stakeholders, communicating tradeoffs and progress clearly

• Prior hands-on experience in at least one of the following using Linux: distributed and/or highly-concurrent systems; low-latency and/or high-volume transaction environments

• Proficiency in Rust and/or C++; comfort operating in a team split across C++, Rust, Go, and Python

• Demonstrated knowledge of order types, trading systems, and financial products

• Experience with Aeron or similar messaging/transport systems a strong plus

• Comfort with multicast-based market data distribution a plus

• Cryptocurrency/blockchain familiarity highly preferable
