Applied Research Scientist PhD Intern (Summer 2025)

Grammarly is excited to offer a remote-first hybrid working model. Grammarly team members in this role must be based in the United States, and, depending on business needs, they must be able to meet in person for collaboration weeks during the internship, traveling if necessary to the hub(s) where their team is based.

This flexible approach gives team members the best of both worlds: plenty of focus time along with in-person collaboration that fosters trust and unlocks creativity.

The opportunity 

To achieve our ambitious goals, we’re looking for motivated PhD interns to join our Strategic Research team for three months in the summer of 2025. ​​The Strategic Research team develops novel AI algorithms bespoke to Grammarly's product offerings, informs critical decisions, explores novel research spaces, uncovers new capabilities, and paves the way for new AI-powered features. The team collaborates with industry and academia to advance the company's research and development efforts. We seek students who, ideally, are nearing the completion of their PhD and have a background in natural language processing, machine learning, and deep learning. 

This intern will contribute to multiple challenging problems, including writing assistance, controllable text generation, summarization, personalization, responsible AI, and many others. Our Research team actively publishes in leading journals and participates in conferences, all while creating the next generation of features and product offerings for tens of millions of daily active users. 

Grammarly’s engineers and researchers have the freedom to innovate and uncover breakthroughs—and, in turn, influence our product roadmap. The complexity of our technical challenges is growing rapidly as we scale our interfaces, algorithms, and infrastructure. You can hear more from our team on our technical blog.

As an Applied Research Scientist PhD Intern, you’ll work with our research scientists, engineers, and linguists. Most of the problems we’re tackling haven’t yet been solved elsewhere, providing the opportunity for creativity and innovative problem-solving. In this role, you will apply your knowledge and learn new skills to improve our writing assistance systems. You will conduct foundational, exploratory research, pushing the field's boundaries and powering the next generation of writing assistance tools.

In this role, you will:

• Work alongside a group of top-notch researchers to design and implement SoTA DL and NLP algorithms to solve challenging research problems that are the core of  Grammarly’s AI features.
• Produce sound experimental results to enable decision-making as we iterate on projects.
• Be results-oriented in the face of ambiguous problems and uncertain outcomes.
• Contribute to the broader research community by publishing research papers in machine learning, natural language processing, and related areas.

Qualifications

• Is currently enrolled in a PhD.
• Has solid theoretical and practical knowledge of machine learning, with a focus on natural language processing. 
• Has experience developing novel deep learning algorithms and training LLMs.
• Has a proven track record in independently conducting SoTA AI research, evidenced by publishing at top-tiered conferences.
• Is proficient with Python and familiar with ML frameworks and tools, such as PyTorch, JAX, HuggingFace, and Langchain.
• Is passionate about contributing to AI research breakthroughs that can improve the communication for everyone.
• Can solve large, complex problems with multiple stakeholders and no obvious solutions.
• Takes the initiative and drives results.
• Applies creativity to solve problems that haven’t been solved before.
• Follows the data ruthlessly, looking for evidence to disconfirm hypotheses and changing perspectives when the data indicates.
• Is available for the entire duration of a twelve-week program. 
• Embodies our EAGER values—is ethical, adaptable, gritty, empathetic, and remarkable.
• Is inspired by our MOVE principles, which are the blueprint for how things get done at Grammarly: move fast and learn faster, obsess about creating customer value, value impact over activity, and embrace healthy disagreement rooted in trust.
• Can collaborate in person for 2 weeks during the summer, traveling if necessary to our US hubs. 

Compensation

The expected pay for this position is $74.00 - $83.00 USD/hour and may be modified in the future.
