Obsidian Capital is a proprietary high-frequency trading firm in Ahmedabad, building ultra-low-latency systems that trade Indian markets with our own capital. Tiny, hungry team. Big ambitions. The code you ship moves P&L; the next trading day — not the next quarter.

We are hiring a Software Developer to build and maintain the systems our traders and quantitative researchers use every day. You will work across our trading platform, write performance-critical code in C++ and Python, and own features end-to-end from design to production.

What you'll do

- Design, develop, test, and maintain components of our trading and research platform
- Write low-latency, high-throughput code in C++ and Python
- Build internal tools and infrastructure used directly by traders and quant researchers
- Diagnose and resolve issues in live production trading systems
- Collaborate with cross-functional teams — traders, researchers, and other engineers — on project delivery
- Profile, benchmark, and optimize hot paths in production code

Requirements

Must have
- 1 – 3 years of professional experience building production software systems
- Robust proficiency in C++ and Python




- Hands-on experience with multithreading and multiprocessing
- Solid grasp of data structures, algorithms, and software design patterns
- Comfort working in Linux environments
- Genuine interest in financial markets and algorithmic trading
- Bachelor's degree in Computer Science, Engineering, or a related field (any graduate considered for exceptional candidates)

Nice to have

- Experience building latency-sensitive or systems-level applications
- Exposure to network programming, sockets, or kernel-bypass stacks
- Prior work in quantitative finance, trading, or market data systems
- Contributions to open-source systems projects

Benefits

• Compensation: INR 24 – 36 LPA, based on experience
- Year-end performance-linked bonus
- Direct ownership of high-impact work in a small, focused team
- Exposure to the full stack of a proprietary trading business — research, execution, risk, infrastructure
- Work alongside traders, researchers, and engineers in one room
- On-site role in Ahmedabad — immediate joining preferred
