Software Engineer (C++)

DescriptionSoftware Engineer (C++)The Firm

Teesta Investment is a proprietary high-frequency trading (HFT) and market-making firm focused on global digital asset markets. We build automated trading systems that operate 24×7 across global crypto markets, where software, infrastructure, and quantitative research come together to make decisions in microseconds.

Unlike traditional software, trading systems operate under demanding constraints. Market data is continuous, latency directly influences outcomes, and every layer of the technology stack, from operating systems and networking to execution engines and infrastructure, contributes to performance. Building these systems requires engineers who enjoy solving difficult technical problems with precision and discipline.

At Teesta, engineers work alongside traders and quantitative researchers to design technology that is reliable, scalable, and built for production from day one. We believe great engineering comes from curiosity, ownership, and a relentless focus on continuous improvement.

The Team

This is a full-time, on-site role based in our Kolkata or Mumbai office.

You'll join a small, highly technical engineering team responsible for developing the software that powers our trading platform. The team works closely with traders and quantitative researchers to build systems that process market data, execute trades, and support research across global digital asset markets.

We value engineers who are intellectually curious, enjoy working close to the hardware and operating system, and take pride in writing software that is efficient, reliable, and maintainable.

The Role

Building software for high-frequency trading is unlike building conventional applications.

Trading systems must process large volumes of real-time market data, respond within extremely tight latency constraints, and remain reliable throughout constantly changing market conditions. Performance, correctness, and robustness are equally important, and even small engineering improvements can have a measurable impact.

As a Software Engineer, you'll contribute to the development of the core systems that power our trading platform. Working closely with experienced engineers, you'll build software that combines low-level systems programming with modern software engineering practices.

Depending On Your Experience, Your Work May Include

• Designing, developing, testing, and maintaining high-performance applications using modern C++.
• Building components that process real-time market data and support low-latency trade execution.
• Applying data structures and algorithms to solve complex performance-critical problems.
• Working with operating system concepts to improve application performance, efficiency, and reliability.
