Founding Developer Advocate

About the role

We’re looking for a Senior AI Systems Engineer to build the core engine of Vesper. You won't just be fine-tuning models; you’ll be architecting the bridge between natural language prompts and executable, full-stack application code. You are building the tool that builds tools. Your work will directly impact how the next generation of founders creates software.

Who you are

• You have deep expertise in TypeScript, Node.js, and modern React environments.
• You have experience working with LLM APIs (OpenAI, Anthropic) and orchestration layers.
• You understand Abstract Syntax Trees (ASTs) and how to programmatically manipulate code.
• You care deeply about latency; you want the AI to code as fast as the user thinks.
• You are pragmatic about AI limitations and skilled at implementing guardrails to prevent hallucinations.

What you’ll do

• Design and optimize the "Agent Loop" that plans, writes, and debugs user applications.
• Improve the context management system so Vesper "remembers" large codebases accurately.
• Implement real-time code streaming to minimize time-to-first-token.
• Collaborate with product designers to create seamless generative UI patterns.
• Push the boundaries of what is possible with autonomous coding agents.
