Job description

CTC is a cutting-edge proprietary trading firm with a long-term vision and a clear focus on helping the world price and manage risk. Our fun and trusting culture inspires us to solve the industry’s most challenging problems and take calculated risks in a collaborative environment.

We strive to be the most innovative firm in the industry today, tomorrow, and long into the future while upholding ethical excellence. We believe that CTC makes a positive impact on the markets, the lives of our employees, and all the communities to which we belong. Started in 1995 by a team of forward-thinking Traders, we are proud to call ourselves an industry leader that keeps making markets and each other better.

As a Senior Engineer on the Market Data team, you will play a pivotal role in ensuring reliable and fast delivery of the market data that is foundational to our trading systems. You will build high-performance libraries and services that process vast amounts of real-time data from financial venues across the world—data that all of our trading systems depend on to make critical decisions in the timeframe of microseconds to nanoseconds. Your work will be foundational to every trading strategy we run, and your contributions will be essential to maintaining CTC's competitive edge in this fast-paced trading environment.

What You’ll Do

• Design and build high-performance, low-latency libraries and services that power our global trading platform
• Work closely with traders, quants and technologists to drive ideas from inception to production in a timely and robust manner.
• Partner closely with other teams such as execution, low‑latency and hardware to design and deliver solutions for our next-generation market data platform
• Ensure operational safety and uphold the highest standards of software engineering by thoroughly testing code, following a coherent and maintainable design and architecture, and adhering to best practices—prioritizing carefully planned, well-structured solutions over ad hoc implementations.

What We’re Looking For

• A minimum of 5 years of experience working in a production environment using modern C++
• Experience with low‑latency feed handler development, market data protocols (e.g. MDP3, ITCH)
• Deep knowledge of low level systems programming, optimization, and hardware/software co‑design
• Strong fundamentals in computer architecture and networking protocols
• Experience writing multithreaded and distributed systems with an affinity for delivering clean, performant code
• Ability to quickly triage issues and drive the resolution effort through completion
• Experience working at a high‑frequency trading firm is preferred

Compensation

The salary range for this role is listed below. This role is also eligible for an annual discretionary bonus. The discretionary bonus will be dependent upon the individual’s skills, experience, qualifications, and firm performance.

Salary Range:

• $225,000—$250,000 USD

Most teams at CTC, with the exception of Trading, follow a hybrid workplace model, subject to change based on business need.

Our Benefits

• Generous time off
• Insurance coverage
• Paid parental leave
• Free breakfast and lunch (plus healthy snacks)
• Wellness reimbursement
• Other benefits focused on providing the best employee experience
