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 Software as a Service (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.

What You'll Love:

Zero bureaucracy, zero silos—engineers directly collaborate with traders, researchers, and the CEO
Direct ownership and end-to-end visibility on production systems
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
5-week structured training program:

Your Role: Build What Most Engineers Never Get to Touch

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

You'll be part of a lean, focused team building ultra-low-latency trading systems, real-time exchange simulators, execution algorithms, and alpha forecasting models. Our engineers own the stack—from C++ nanosecond-sensitive infrastructure to Python-based research platforms.

This role is ideal for someone who thrives at the intersection of research and engineering—comfortable building systems, testing hypotheses, and working directly with data that moves markets.

What You'll Work On

Architect and implement:
Execution algorithms across global markets
Exchange simulators and tick-level backtesting frameworks
Smart Order Routing systems across lit and dark venues
Models for market impact, price prediction, and volume forecasting
High-performance trading systems optimized for throughput and latency
Core infrastructure to support new asset classes and global markets
Collaborate closely with global quants, traders, and senior engineers
Analyze system performance across app, OS, and hardware layers

Requirements

You Should Have

Bachelor's or Master's from a top-tier CS, Math, or Engineering program (IIT/NIT/BITS preferred but not required)
6+ years hands-on C++ experience (C++14/17/20) in performance-sensitive applications
Strong fundamentals in data structures, OS, networks, and concurrency
Python fluency for data analysis and prototyping (preferred but not required)
Experience with large-scale, real-time systems (trading experience is a plus but not mandatory)
Passion for learning—markets, systems, and modeling

Bonus Points For

Deep experience with TCP/IP, multi-threading, and latency optimization
Prior work on trading platforms, FIX engines, or exchange protocols
SQL optimization and experience with research or market data pipelines
Contributions to open-source C++/Python performance tools

Benefits

Why This Role Is Rare

Exposure to real-time trading systems live in global markets
Direct mentorship from senior algorithmic trading and software engineering veterans
Blend of research, systems design, and algorithm development
Equity and cash compensation
Zero red tape, no outsourcing mentality
