Currently, we are looking for an experienced Middle Quantitative Developer.
The Role
We are seeking a Middle Quantitative Developer with 3–4 years of experience in building and optimizing high-load, low-latency systems. This is a hands-on engineering role where you will: * Enhance our execution platform and market data infrastructure. * Design and implement connectors for new centralized and decentralized exchanges. * Perform latency profiling and code optimization to achieve maximum throughput and minimal jitter. * Work with large-scale data pipelines to support real-time and historical analysis.
You’ll collaborate directly with quantitative researchers, traders, and other engineers to productionize models and optimize trading strategies.
Responsibilities * Develop and optimize Python-based trading infrastructure for high-performance execution. * Implement and tune parallel and concurrent systems, using frameworks such as multiprocessing, threading, asyncio, aiohttp, Dask, joblib. * Build and maintain data pipelines using NumPy, Pandas, SciPy, with storage in SQL and NoSQL databases (especially ClickHouse, PostgreSQL, Redis). * Architect and scale systems on AWS, leveraging EC2, S3, Lambda, and related services. * Design and integrate with messaging brokers (Kafka, RabbitMQ, ZeroMQ) for distributed trading workflows. * Perform latency analysis, profiling, and performance optimization across trading components. * Contribute to CI/CD, testing, and best practices in code quality.
Requirements * 3–4 years professional Python development in high-performance, high-load environments. * Expert in concurrency and parallel programming (asyncio, multiprocessing, threading, Dask). * Proficiency with scientific computing libraries: NumPy, Pandas, SciPy. * Advanced skills in SQL and NoSQL databases; deep expertise with ClickHouse or equivalent high-volume solutions. * Strong knowledge of AWS (compute, storage, streaming, orchestration). * Strong knowledge of messaging brokers (Kafka, RabbitMQ, ZeroMQ). * Solid foundation in algorithms, data structures, and system design. * Comfortable with Linux environments, Docker, Git.
Nice to Have * Knowledge of Go for latency-critical modules. * Experience with C++/Rust for ultra-low-latency systems. * Familiarity with time-series analysis, quantitative finance, or crypto trading. * Exposure to profiling and debugging tools (perf, flamegraphs, cProfile, PySpy).
