Experienced Software Engineer – Low Level; C++

At Hudson River Trading (HRT), C++ is at the center of our live trading systems and research infrastructure. Our C++ engineers build the highly performant, fault‑tolerant systems that power trading across global markets. HRT’s distributed system is on the Pareto frontier of latency and throughput, giving you limitless opportunity to leverage your deep knowledge of C++, OS internals, CPU architecture, and networking hardware and protocols.

You’ll work side‑by‑side with researchers, traders, and hardware specialists, implementing solutions where every microsecond matters.

Our bottom‑up approach to projects and our highly collaborative environment empower talented engineers to make significant contributions and see their impact daily. At HRT, you’ll be challenged to solve complex problems in a fast‑paced, highly competitive industry, surrounded by some of the brightest minds in the field.

C++ Engineers at HRT work on a wide variety of projects. Examples include:

• Develop and optimize infrastructure for market data, order entry and execution logic, spanning tens of asset classes including options, equities, futures, crypto, and fixed income.
• Design fault‑tolerant, low‑latency systems for live trading, including encoding/prioritization of data over WAN links and recovery from hardware failures.
• Profile and improve performance‑critical code for both throughput and latency in production environments.
• Build and maintain infrastructure that drives products including client‑facing wholesale and SDP platforms, distributed network file systems, and scalable research workflows.
• Write software that interfaces with specialized hardware such as FPGAs and ASICs used in trading systems.

• You’re one of the top devs in your current organization, as measured by productivity, technical capability, and helpfulness to other devs.
• You are capable of solving complex engineering problems independently and providing technical advice for others in areas of your expertise.
• You can make progress on long‑term architectural projects while troubleshooting smaller tasks and bug fixes with agility.
• You can describe software designs at a high level (the abstract interface), low level (step‑by‑step algorithm), or anywhere in between.
• You are always looking for ways to make systems better.

• 1+ years of professional work experience
• Bachelor’s degree in Computer Science, Computer Engineering, or related field
• Superior design, debugging, and problem solving skills
• Advanced C++ experience is required, daily use preferred
• Knowledge of UNIX operating systems (we use Linux), system/processor performance, and network communication

The estimated base salary range for this position is $200,000 to $300,000 per year, based on job‑related skills and experience. This role will also be eligible for discretionary performance‑based bonuses and a competitive benefits package.
