You will work closely with Low-Latency Software Developers, Core Engineers, Infrastructure Engineers, and Quantitative Trading teams to design and optimize systems where every microsecond matters.

The ideal candidate has a strong background in Linux systems programming, networking internals, modern C++, and high-performance computing (HPC). You will be responsible for designing and optimizing networking stacks, reducing system latency, improving throughput, and building highly efficient software for production trading environments.

Key Responsibilities:

Design, develop, and optimize high-performance system software using Modern C++.
Build ultra-low latency networking solutions for electronic trading platforms.
Develop and optimize kernel bypass networking applications using technologies such as DPDK, Solarflare/OpenOnload, AF_XDP, RDMA, or equivalent.
Design high-performance packet processing pipelines and network communication frameworks.
Optimize TCP/IP, UDP, multicast, and socket-based communication for deterministic latency.
Analyze and improve system performance across CPU, memory, storage, networking, and operating system layers.
Develop low-level libraries and infrastructure for market data distribution and order execution.
Collaborate with Low-Latency Software Developers and Infrastructure Engineers to enhance overall trading system performance.
Profile, benchmark, and optimize applications using modern performance analysis tools.
Investigate production performance issues and implement scalable, long-term engineering solutions.
Contribute to system architecture, code reviews, and engineering best practices.

Required Qualifications:

Bachelor’s, Master’s, or Dual Degree in Computer Science, Electrical Engineering, Electronics Engineering, Mathematics & Computing, or a related discipline from a premier institute or leading university.
2+ years of experience in Systems Programming, High-Performance Computing (HPC), Low-Latency Infrastructure, Networking, or Distributed Systems.
Strong expertise in Modern C++ (C++17/20), STL, multithreading, and concurrent programming.
Excellent understanding of Linux internals, operating systems, memory management, scheduling, and process architecture.
Strong understanding of networking fundamentals including TCP/IP, UDP, multicast, sockets, and network protocol optimization.
Experience with Linux systems programming and performance optimization.
Strong debugging, profiling, and analytical problem-solving skills.

Preferred Experience:

Candidates should have experience in several of the following:

Kernel bypass technologies such as DPDK, AF_XDP, Solarflare/OpenOnload, RDMA, or XDP/eBPF.
High-performance packet processing.
Linux Kernel internals and systems programming.
CPU cache optimization, NUMA architecture, CPU affinity, huge pages, and memory optimization.
Lock-free programming and concurrent data structures.
Network stack optimization and NIC tuning.
Performance profiling using perf, VTune, Valgrind, gdb, or similar tools.
High-performance messaging frameworks.
Electronic Trading, High Frequency Trading (HFT), FinTech, Telecommunications, or High- Performance Computing environments.
Build systems, CI/CD pipelines, Git, and modern software engineering practices.

What We’re Looking For:

We’re looking for engineers who:

Are passionate about systems programming and performance optimization.
Enjoy solving low-level engineering challenges that demand precision and efficiency.
Have a deep curiosity about Linux internals, networking, and computer architecture.
Write clean, maintainable, and highly optimized C++ code.
Thrive in collaborative, high-performance engineering environments.
Continuously push the boundaries of latency, throughput, and system efficiency.

Why Join Open Futures?

Build the technology that powers one of India’s leading High Frequency Trading firms.
Work on cutting-edge low-latency infrastructure where every microsecond matters.
Collaborate with exceptional engineers, quantitative researchers, and traders.
Access enterprise-grade hardware, advanced networking technologies, and modern development tools.
Competitive compensation with attractive performance-linked incentives.
Solve some of the most challenging engineering problems in high-performance computing and electronic trading.
Clear career progression into Senior Systems Engineering, Low-Latency Engineering, or Technical Architecture roles.

If you’re passionate about Linux systems, networking, and building ultra-low latency infrastructure at scale, we’d love to hear from you.
