I’m Brian, the Founder and CEO at Replay.  We’ve recently launched a new API and no-code tool Nut centered on making AIs great at debugging.  We’re building on our five years of history and unique low-overhead Chromium recorder to deliver a product with incredible capabilities that will greatly expand the capabilities of AI developers.  We’re a small company but are well funded by Andreessen Horowitz, IA Ventures, Version One, and other investors.  We’re staffing up to best pursue this opportunity.

The Role

AI generated code often needs to be modified to meet the desired goals of an application or may have bugs when applied to various use cases.  As an applied AI lead, you’ll work directly with our CEO/founder to develop the core technology behind our API that identifies and explains problems in recordings of application code executions.  Advance our technology using AI to identify and resolve bugs in code and to modify AI generated code developed for particular app features and use cases.  Play a significant role in developing AI tools that allow software developers to use AI to write better, more efficient and bug free code.

Responsibilities

• Use LLMs in concert with tools based on traditional program analysis techniques like control dependency analysis and dataflow analysis to advance our technology.
• Review reports shared by users and identify patterns where our API falls short.
• Design improvements to the AI and its tools for solving new problems and building out our evals.
• Optimize the reliability of the API and the consistent performance on our evals.

Your Expertise

• You have a track record building new technology using AI based analysis.
• BS and/or Master/PhD degree, preferably in CS, or equivalent experience
• Passionate about enabling great user experiences using AI - particularly for developers
• Passionate about careful design and construction of robust analyses and evals
• Excellent communication and collaboration skills and the ability to work well within engineering organization and cross functions
• Love collaborating via code reviews, architecture discussions, and are motivated to improve their teammates’ productivity
• Strong product focused coding skills
• Experience working with TypeScript and React applications is highly desired
