Machine Learning Research Intern
Modal Labs · New York, NY · San Francisco, CA
Research intern on the research team working on reinforcement learning, machine learning and foundation models. Work involves improving methods for large-scale model training, optimization and inference, extending models to long-context and long-horizon tasks, and improving inference-time efficiency, reliability and robustness.
What you'll do
- Improve existing methods and develop new techniques for large-scale model training and optimization
- Extend models to long-context and long-horizon tasks
- Improve inference-time efficiency, reliability and robustness
- Translate research ideas into working implementations
- Collaborate across research and engineering teams
Nice to have
- Currently pursuing a PhD in computer science, machine learning, or a related field
- Demonstrated research record in reinforcement learning, machine learning, or foundation models
- Experience developing and evaluating large-scale models or ML systems
- Familiarity with distributed training, large-scale inference, or multi-GPU environments
- Publications at leading venues such as NeurIPS, ICML, ICLR, CVPR, CoRL, UAI, JMLR, or TMLR
- Strong programming and engineering skills
- Collaborative, mission-driven mindset

Full original description
About Us:
AI needs a new infrastructure layer. We're building it at Modal.
Every era of computing brought new workloads that previous infrastructure couldn't support: mainframes, databases, and the cloud. Each time, the company that rebuilt the layer underneath defined the decade. AI is no different, except it touches everything instead of one slice, and the window to build the layer underneath it is open right now.
Our customers include category-defining companies like Lovable, Ramp, Cognition, DoorDash, and Suno. They rely on Modal for instant GPU access, sub-second container starts, and native storage, so it's simple to serve low-latency inference, fine-tune models, and access production-ready sandboxes at scale.
We recently raised a $355M Series C at a $4.65B valuation, led by General Catalyst and Redpoint Ventures. We've crossed $300M+ ARR and grown fivefold since September.
Our team includes creators of popular open-source projects (e.g.,Seaborn,Luigi), academic researchers, international olympiad medalists, and experienced engineering and product leaders with decades of experience.
The Role:
We are looking for PhD research interns with strong research experience in reinforcement learning, machine learning, and foundation models, including large language and multimodal models, to join our research team. This internship is well suited to candidates interested in improving existing methods and developing new techniques for large-scale model training, optimization, and inference, extending models to long-context and long-horizon tasks, and improving inference-time efficiency, reliability, and robustness in high-stakes real-world deployments.
Preferred Qualifications:
Currently pursuing a PhD in computer science, machine learning, or a related field.
A demonstrated record of research in reinforcement learning, machine learning, foundation models, or related areas.
Experience developing and evaluating large-scale models or machine learning systems.
Familiarity with distributed training, large-scale inference, or multi-GPU environments.
Publications at leading venues such as NeurIPS, ICML, ICLR, CVPR, CoRL, UAI, JMLR, or TMLR.
Strong programming and engineering skills, with the ability to translate research ideas into working implementations.
A collaborative, mission-driven mindset and the ability to work effectively across research and engineering teams.
