Software Engineer (C++) (INDIA)

Trexquant is a growing systematic fund at the forefront of quantitative finance, with a team of world-class researchers and engineers. As we continue to expand our trading operations, we are investing heavily in building the next generation of our quantitative research & trading platform.

Our Infrastructure Engineers are embedded within the following teams:

• C++ Trading Engineer

As a member of the Engineering team, you will focus on developing high-performance trading systems, designing and optimizing short-term trading signals in a high-frequency environment with strict latency and efficiency requirements. You will also support independent trading activities by building robust C++ systems, collaborating with researchers and technologists, and delivering solutions that have a direct and measurable impact on trading performance.

• C++ Simulation Engineer

As a C++ Simulator Engineer, you will work closely with quantitative researchers and traders to design, develop, and optimize high-performance systems for algorithmic trading. Your responsibilities will include building and maintaining the core infrastructure for trading simulations.

• Data Infrastructure Engineer

As a member of the Data team, you will focus on financial and market data development, building scalable, distributed pipelines for systematic web scraping and ingestion of diverse data sources, with strict latency and reliability requirements. You will also work on developing exchange connectivity solutions by creating high-performance C++ handlers to capture, process, and integrate real-time market data feeds.

When you apply for an Infrastructure role at Trexquant, we will first assess you on the core skills required for the Engineering team. During the interview process, we will be able to get to know you better, learn about your strengths and match you to the best team that closely aligns with your skills and preference.

Responsibilities:

• Full lifecycle development of low-latency/high-throughput research and trading systems using C++ & Python
• Build and optimize data processing pipelines to ensure reliable access to large, high-quality datasets.
• Assist in developing tools for back testing, model training, and strategy evaluation.
• Collaborate with researchers and traders to deliver technical solutions that improve research productivity and trading performance.
• Participate in code reviews, testing, and documentation to maintain high-quality standards.
• Stay abreast of emerging technologies, tools, and best practices, bringing innovative ideas to continuously improve our systems.

Requirements

• Bachelor’s, Master’s, or PhD in Computer Science or a related STEM discipline.
• Minimum 2 years of experience in C++ software development within demanding, real-time environments.
• Strong expertise in modern C++ (C++17/20), including advanced features such as template metaprogramming
• Demonstrated experience in building high-throughput, low-latency systems.
• Strong understanding of Linux fundamentals and systems-level programming.
• Familiarity with distributed systems and related technologies (e.g., Kafka, Redis, HTCondor) is a plus.
• Working knowledge of Python and its numerical ecosystem (NumPy, SciPy).
• Strong analytical thinking and problem-solving skills, with the ability to operate independently in a fast-paced environment.

Good to Have:

• Experience working with matrix computation and optimization (Blaze, OpenBLAS, LAPACK)
• Experience working with live market data and exchange feeds.
• Experience profiling and tuning production Linux systems for high throughput.
• Experience working with time-series processing or event driven systems.
• Experience working across C++ and Python boundaries, such as with bindings (pybind11, C API), embedded Python, hybrid pipelines and orchestration.
• A background in finance is preferred but not required

Benefits

• Competitive salary plus bonus based on individual and company performance
• Work in a collaborative and friendly environment, participate in the decision-making process for research direction, and have the opportunity to lead on new ideas.
• Comprehensive benefits including healthcare and insurance.
