Senior C++ Software Engineer (Algo Trading)

Job description

About BestEx Research
BestEx Research is a financial technology and research firm specializing in building sophisticated execution algorithms and transaction cost modeling tools servicing multiple asset classes.

The firm provides high-performance algorithmic execution services to hedge funds, CTAs, asset managers, and banks through a traditional electronic broker and in a broker-neutral SaaS model.


Its cloud-based platform, Algo Management System (AMS), is the first end-to-end algorithmic trading solution for equities and futures that delivers an entire ecosystem around execution algorithms, including transaction cost analysis (TCA), an algorithm customization tool called Strategy Studio, a trading dashboard, and pre-trade analytics in a single platform.

The platform is currently live for U.S., Europe, and Canadian equities and global futures trading.


BestEx Research is disrupting a $100 billion industry by challenging the status quo of stale, black-box solutions from banks and offering next-generation execution algorithms that combine performance improvement with transparency and customization.

BestEx Research uses leading-edge technology to support its low-latency, highly scalable research and trading systems, with its backend in C++, research libraries in C++/Python and R, and web-based technologies for delivering its front-end platforms.


BestEx Research’s mission is to become the leader in automation and measurement of execution across asset classes globally and significantly reduce transaction costs for our clients.

Why Join Us?
BestEx Research’s Bangalore office is not an “offshore center.” It’s a core engineering and research hub—working on the exact same problems and projects as our U.S. team.

You’ll be part of the global brain trust, solving some of the hardest problems in trading, systems, and data science.


What You’ll Love:
Zero bureaucracy, zero silos—engineers directly collaborate with traders, researchers, and the management team.


Direct ownership of subsystems.


Daily opportunity to learn from pioneers in HFT, low-latency systems, and algo trading.


A high-trust environment, where performance speaks louder than hierarchy.


Competitive compensation in India, including equity and cash bonuses.


Ability to transition between various teams and projects, whether related to trading systems, algorithmic trading or system tooling
5-week structured training program:
Market microstructure and trading mechanics
Algorithmic execution and strategy design
Exchange simulators and performance testing
Market data systems and real-time analytics
Hands-on exercises using production research data
Continuous professional development, with refresher courses, advanced sessions, and on-demand training tailored to your growth.


Global exposure: Opportunities to collaborate with, visit, or relocate to our U.S., Singapore, or London offices, based on performance and business needs.


Your Role: Build What Most Engineers Never Get to Touch

Enhancing existing systems :
Add support for new features and improve scalability and reliability
Collaborating closely with :
A global team of quants, traders, and senior engineers to design cutting-edge solutions
Analyzing and optimizing system performance :
Across application, OS, and hardware layers to achieve industry-leading performance
Work primarily with C++17 in a high-impact, low-bureaucracy environment
You Should Have:
Bachelor’s or Master’s from a top-tier CS or Engineering program (IIT/NIT/BITS preferred but not required)
At least 5+ years software development experience with C++
Expert-level knowledge of C++ and excellent software design skills
Expert-level knowledge of TCP/IP and multithreading
Excellent problem solving and analytical skills
Excellent communication skills and ability to articulate ideas
An attitude of constant curiosity and growth, as well as the ability and desire to mentor others
While domain experience is a plus, we welcome strong engineers from other industries
Bonus Points For
Database optimization and experience with research or market data pipelines
