- Strong commercial experience developing software in modern C++.
- Experience building Linux-based distributed systems.
- Strong understanding of concurrency, multithreading and performance optimisation.
- Experience working within high-throughput, latency-sensitive or real-time environments.
- Proven track record of delivering production systems in fast-paced engineering teams.
- Excellent problem-solving abilities and a desire to tackle technically challenging problems.
- Strong communication skills and an ability to work directly with end users and stakeholders.
Desirable Experience
- Financial markets, electronic trading, market data, exchange connectivity or quantitative research experience.
- Experience with Kafka or similar streaming technologies.
- Experience with Python and/or Java alongside C++.
- Knowledge of modern data architectures, data lakes and large-scale data platforms.
- Exposure to derivatives, options, fixed income, commodities, ETFs, digital assets or systematic trading environments.
- Experience with Airflow, Dagster, Apache Iceberg, Delta Lake or similar technologies.
Why Consider It?
- Direct interaction with traders and quantitative researchers.
- Greenfield and highly impactful engineering work.
- Large-scale distributed systems and real-time data challenges.
- Strong engineering culture with significant autonomy and ownership.
- Opportunity to work alongside some of the industry's strongest technologists.
- Competitive compensation and long-term career development.
This role is particularly well suited to C++ engineers from trading firms, market makers, hedge funds, exchanges, market data providers or tier-1 bank electronic trading teams who enjoy building high-performance systems that sit close to the trading process.
