## **About JoyWork**

JoyWork is a VC-backed San Francisco startup managing cash flow for mid-market and enterprise service businesses. Our AI agent chases what customers owe by email, SMS and voice, and watches the workflows upstream of billing so every invoice goes out accurate. Finance teams get their time back for the work that needs their judgment.

## **The role**

• You build across the whole product. Examples: the AI agent, email and voice, the web app, ERP integrations, data and metrics.

• You own your work end to end: design, build, test, ship to production, and keep it running.

• You work with customers directly, including deploying what you build for them.

• You work closely with the team every day.

## **What we expect**

• You care about the problem and about our customers. You want to see them succeed with JoyWork, and their success is how you prove your impact.

• You ship fast and ship right: production quality, every time.

• You prove things work and say plainly where they don't.

• You make product calls instead of only taking tickets.

• You use AI tools every day and are accountable for what they produce.

## **Technical skills**

• Full-stack web development in a typed language.

• Relational databases: data modeling and SQL.

• Building with LLM APIs: structured output, evaluation, handling a slow or wrong response.

• Tests that catch real bugs, and knowing what each one proves.

• You have built and shipped something people use.

## **Logistics**

• Remote or on-site in San Francisco.

• Based in the US or Canada, with authorization to work where you live.

• Strong interns can convert to a full-time role.

• An NDA and an IP assignment covering everything you build for JoyWork, signed before any access to code or customer data.
