Graduate Quantitative Developer

DeepFin Research; New York (NY); Vor Ort; USD 90.000 - 150.000; Vollzeit

Zusammenfassung

DeepFin Holdings Ltd in New York seeks a Junior Quant Developer to productionise Python research into robust C++ trading systems. You’ll translate prototypes, build backtesting and simulation infrastructure, and support strategy development using L3 market data across venues.

This hands-on, engineering-heavy role lets you own components end-to-end, improving latency, throughput, and tooling with researchers and infra engineers.

Qualifikationen

• Bachelor's or Master's in CS, Engineering, Math, or Physics.
• 0-3 years experience in quantitative finance or data-intensive roles with C++.
• Strong C++ knowledge: memory, ownership, STL, performance-focused coding.
• Python for analysis, tooling, and debugging (pandas/NumPy a plus).
• Exposure to market microstructure and L3/order book data.
• Builder mindset: end-to-end ownership, shipping iteratively.

Aufgaben

• Productionise research models into C++: translate Python prototypes into efficient, maintainable C++ production code.
• Backtesting & simulation: build and improve simulation systems that reflect real market mechanics (order book, fills, cancels, exchange rules).
• L3 market data handling: ingest and process high-volume tick/order-level feeds; create reliable feature pipelines from raw exchange data.
• Performance optimisation: improve latency and throughput of backtests/sims (profiling, memory optimisation, data structures, parallelism where appropriate).
• Research support tooling: create utilities for data inspection, experiment tracking, run orchestration, and post-trade analytics in Python.
• Debugging & correctness: investigate mismatches between simulation and production behaviour; diagnose edge cases and implement fixes with strong test coverage.
• Cross-team collaboration: work daily with researchers and infra/exec engineers to ship improvements from idea test production.

Jobbeschreibung

DeepFin is a systematic proprietary trading firm combining deep learning, traditional quantitative research methods, and cutting-edge trading technology, to trade global markets. Founded by engineers and researchers, we build and deploy advanced trading systems that operate across global markets. We value curiosity, precision, and collaboration, and we're building an environment where exceptional people can do their best work at the intersection of AI and financial markets.

Junior Quant Developer Backtesting, Simulation & Research, Productionise Research (C++/Python)

Role Overview We're hiring a junior Quant Developer to help productionise research into robust, high-performance trading systems. You'll work closely with Quant Researchers and senior engineers to convert Python research code into production C++, build and optimise backtesting / simulation infrastructure, and support strategy development using L3 market data across multiple venues. This is a hands-on, engineering-heavy role in a fast-moving environment: you'll own components end-to-end and contribute directly to research velocity and trading PnL.

Key Responsibilities

• Productionise research models into C++: translate Python prototypes into efficient, maintainable C++ production code.
• Backtesting & simulation: build and improve simulation systems that reflect real market mechanics (order book, fills, cancels, exchange rules).
• L3 market data handling: ingest and process high-volume tick/order-level feeds; create reliable feature pipelines from raw exchange data.
• Performance optimisation: improve latency and throughput of backtests/sims (profiling, memory optimisation, data structures, parallelism where appropriate).
• Research support tooling: create utilities for data inspection, experiment tracking, run orchestration, and post-trade analytics in Python.
• Debugging & correctness: investigate mismatches between simulation and production behaviour; diagnose edge cases and implement fixes with strong test coverage.
• Cross-team collaboration: work daily with researchers and infra/exec engineers to ship improvements from idea test production.

Requirements

• Education: Bachelor's or Master's from a top university in Computer Science, Engineering, Math, Physics, or similar.
• 0-3 years experience in quantitative finance or other relevant data-intensive industries working with C++
• Strong working knowledge of C++ (memory, ownership, STL, performance-aware coding).
• Experience: demonstrable evidence of hands-on systems work in C++ handling large-scale data (internships, research labs, competitive projects, open-source).
• Comfortable with Python for analysis, tooling, and debugging (pandas/numpy/Jupyter a plus).
• Exposure to quantitative finance, eg through internships/university societies, including market microstructure and L3/order book data.
• Clear "builder mindset": you like owning problems end-to-end, shipping incrementally, and iterating quickly.

If you're passionate about applying advanced technology to real-world markets and want to work alongside a focused, high-performing team, we'd love to hear from you. DeepFin offers a collaborative, research-driven environment where ideas move quickly from concept to execution and where every contribution has visible impact. Join us in building the next generation of deep-learning-driven trading systems - shaping the future of finance through innovation, rigour, and technology.
