Job summary

Susquehanna International is offering a 10-week Machine Learning Engineering Internship aimed at students passionate about building scalable ML systems within trading environments.

You'll work on training pipelines across GPU infrastructure, inference in production systems, and data infrastructure for large market datasets, with mentorship from experienced engineers and researchers.

Qualifications

• Pursuing a technical degree and planning to graduate by Aug 2028.
• Strong Python programming skills and familiarity with C++.
• Hands-on experience with ML frameworks beyond API calls (e.g., training at scale).
• Exposure to distributed training, GPU programming, orchestration, or large-scale data processing.
• Experience with GPU kernel programming (CUDA, Triton, CuTe DSL).
• Solid CS fundamentals: data structures, algorithms, concurrency.
• A project/open-source contribution you can discuss in detail.

Responsibilities

• Build and optimize training pipelines on GPU infrastructure.
• Work on inference and deployment for production trading systems.

Overview

Our Machine Learning Engineering Internship is a 10-week immersive experience designed for students who are passionate about building the systems at the intersection of machine learning, large-scale data, and markets.
As a Machine Learning Engineering Intern, you'll work on high-impact projects that closely reflect the challenges and workflows of our full-time engineering team. You'll apply your software engineering skills to real machine learning systems while developing a deep understanding of how machine learning integrates into Susquehanna's research and trading systems. A model is useful only if it can be trained quickly, fed reliably, and run fast enough to act on - our engineers own the systems that make that true, and we scope intern projects the same way.
Susquehanna's proprietary datasets and computing infrastructure - including a rapidly growing cluster of thousands of high-end GPUs - support computationally intensive training, simulation, and rapid experimentation. Engineering teams here are small and highly collaborative, ideas are debated openly, and work that proves out reaches production quickly.

What You Can Expect

• Build and optimize training pipelines that run across our GPU infrastructure, including distributed training for large models
• Work on inference and deployment — the latency, throughput, and cost of models running in production trading systems
• Develop the data infrastructure behind our research, moving large and noisy market datasets through ingestion, storage, and transformation
• Profile and benchmark machine learning workloads, and contribute to the internal libraries and open-source tools our researchers rely on every day
• One-on-one mentorship from experienced engineers and researchers
• Participate in a comprehensive education program with deep dives into Susquehanna's ML, quant, and trading practices
• No prior finance background required

What We're Looking For

• Currently pursuing a Bachelor's, Master's, or PhD in computer science, machine learning, electrical engineering, mathematics, physics, statistics, or a related technical field. Intention to graduate and begin full time employment by August 2028
• Strong programming skills in Python, working comfort in a systems language such as C++, a plus
• Hands-on experience with machine learning frameworks such as PyTorch or JAX that goes beyond calling the API - training at scale, extending a library, or making an existing workflow measurably faster
• Exposure to the systems machine learning runs on: distributed training, GPU programming, orchestration, or large-scale data processing. We're more interested in what you did with a tool and what it changed than in seeing it named on a list
• Experience with GPU kernel programming in CUDA, Triton, or CuTe DSL
• Solid computer science fundamentals: data structures, algorithms, concurrency, and an understanding of how software behaves on real hardware
• A project, system, or open-source contribution you can walk through in detail - what you designed, what you decided, and what you specifically did
• Deep interest in solving complex problems and a drive to innovate in a fast-paced, competitive environment
