Summary

Working with our team of core trading systems developers to improve and expand the functionality of our matching engine, order entry mechanisms, and market data publication. We design, develop, deploy, and support real-time systems for our digital asset trading platform. Time is measured in microseconds and we aim to start measuring in nanoseconds. Reliability, fault tolerance, recoverability, throughput, and latency are what we look for in our systems. If something on the spaceship is broken we aim to fix it, if something can be automated we automate it, and we ship our code weekly.

Responsibilities:

1. Use engineering principles to identify and measure risk and to implement quantitative and technical risk management solutions in software.
2. Understand business needs, facilitate and develop process workflows, data requirements, and specifications required to support implementation of our real time exchange.
3. Develop scalable architecture for the future state of our exchange and contribute towards improving the trading infrastructure.
4. Write robust code and APIs to support the company’s vital business.
5. Keep everyone informed about the health and viability of the platform by reporting known issues and status of ongoing investigations.
6. Identify and advocate for changes vital to the stability and supportability of the system.
7. Mentor and advise teammates to ensure new features are efficient, highly available, and fault tolerant.
8. Provide continuity and stability to the production environment.
9. Provide quick response to production issues to help eliminate down time thereby ensuring high availability and performance of our trading platform.
10. Coordinate, prioritize and plan the changes to our trading software thereby ensuring smooth exchange migrations, quick time to market for new features and software.

Minimum Qualifications:

1. 3+ years Java/C++ or functional programming language experience in an exchange/trading systems environment.
2. Experience with unit testing frameworks and continuous integration tools.
3. 3+ years working with order handling or matching engines.
4. 3+ years working with FIX or other market data/order protocols.
5. Experience in building real time Linux systems.
6. Solid understanding of IP multicast and TCP protocols.

Preferred Qualifications:

1. Low latency/lock-free development and design.
2. Multithreading and concurrency experience.
3. Binary or custom protocols (e.g. ITCH/OUCH).
4. Linux kernel tuning and optimization.
5. Scala experience.
