About Replit
We’re building the world’s most ubiquitous programming environment. We focus on inspiring creativity and generating value for creators through community, and we design simple yet scalable infrastructure primitives for the next generation of creators. We want to blur the line between learning and making– a place where you can hang out, tinker with ideas, learn new concepts, and launch a business all in the same day.

About the role
Your charter is to harness Artificial Intelligence to improve the daily lives of millions of coders using Replit. You will help build new and delightful product features, develop powerful new capabilities for our users, and optimize our robust computing platform.

Examples of what you could do:

• Train and fine-tune a Large Language Model (LLM) for code generation
• Develop sophisticated prompting strategies to make the best use of 3rd-party LLMs via API
• Create and curate large datasets, both from publicly-available sources and from Replit platform data

You will…

• Build novel AI models end-to-end, finding a good balance between state-of-the-art and pragmatism
• Work with a variety of large, unstructured data sources to train and test models
• Deploy LLM-based applications in production, evaluating and improving their performance over time
• Collaborate across multiple engineering teams to integrate AI solutions into our systems and processes
• Identify new opportunities for AI solutions throughout the organization, and set the direction and roadmap required to implement them

You are…

• A very experienced Python developer
• Someone who has a minimum of 5 years of experience in AI (at large)
• Someone who values simplicity and pragmatism (i.e., you think radically but ship incrementally)
• Experienced in building data infrastructure that is both scalable and extensible
• Self-directed and comfortable working autonomously
• Passionate about using AI to make programming accessible to all

Bonus Points if you have:

• Experience with large-scale distributed compute and cloud infrastructure
• Experience working with and fine-tuning Large Language Models (LLMs)
• Experience building scalable applications with LLMs, using frameworks such as LangChain, LlamaIndex, etc.
• Experience as tech lead and/or manager -- the role is perfectly suited for an IC, but there is opportunity for quick growth towards a hybrid role (especially in case of past experience as a TL / manager).
