Sr. AI Engineer

About the Role

We are looking for a Senior AI Engineer who moves fast, experiments relentlessly, and ships agentic AI systems that solve real problems.

Who you are:

• A doer: you're hands-on with code and you experiment daily
• Fast and intelligent: you make smart decisions quickly and iterate
• Experimentation-obsessed: you validate through building
• Comfortable with ambiguity: you forge ahead when the path isn't clear

• Build and deploy agentic AI systems
• Perform research spikes to evaluate scope and feasibility
• Create working prototypes and rapid experimentation
• Create evaluation datasets, labeling workflows, and instrumentation to improve agent performance
• Move from idea to production-ready implementation at speed

• 6+ years of engineering experience shipping impactful products
• 1+ years building agentic AI systems
• Strong product sense and you have an understanding on how to integrate agents into user experiences
• Experience with agentic frameworks. We use Mastra AI, so either experience with or a willingness to learn Typescript
• Bias toward action and rapid decision-making

• ML engineering or data science background
• Experience with evaluation frameworks, observability tools, or synthetic data generation
• History of 0-to-1 projects

$160,000 - $210,000 plus benefits, bonus opportunities and stock options. Final salary may vary depending on skills, location, and/or experience.
