Founding Engineer

You’ll be our second engineer, working directly with Caddy’s founders on core architecture, product direction, and execution. If you’re excited about real-time systems, agentic workflows, and building a product you’ll use every day, you’ll have outsized impact here.

You will own large, ambiguous problems end-to-end: from choosing the approach to shipping new features, operating them in production, and iterating based on user feedback.

We work in person out of our SoHo office.

What we’re looking for

Obsessed with building a product that not only our users love, but that you love and want to use every day
Can make and defend thoughtful product and technical tradeoffs
Thrive in ambiguity and default to ownership
Care about correctness, performance, and user experience
Move fast and with intention
Strong opinions, loosely held

What you’ll do

Own core systems for real-time voice → intent → action workflows
Design APIs/services for long-running, stateful agent tasks
Ship user-facing features with strong quality and polish
Improve reliability, observability, and performance as we scale
Help set product direction and company culture as the team grows

Our tech stack

Our tech stack is pragmatic and evolving. We care more about strong fundamentals than specific tools.

TypeScript (required)
Swift, Objective-C (bonus)
