Job Title: Founding Product Engineer

Salary: $130K-$160K + 0.20%-0.40% Equity

Company Description: Asteroid - YC-backed startup building browser-based AI agents

Job Description:

You will invent new design paradigms for human-agent supervision at scale. As a founding engineer, you'll own the entire user experience from greenfield design systems to mission-critical browser agent interfaces. This role is for a product-obsessed builder with elite taste who wants to define how the world interacts with the next generation of AGI.

Location: San Francisco, USA

Why this role is remarkable:

• Shape the interface of the future by designing how humans supervise agent workforces across complex, exception-heavy healthcare and enterprise workflows.
• Join a world-class founding team backed by Y Combinator (W25) and top angels from OpenAI and Hugging Face in a high-growth environment.
• Enjoy complete greenfield ownership over the platform's UX and design system, moving far beyond simple chat windows into novel AI-native interactions.

What you will do:

• Build and own the end-to-end platform UX, including a unified design system and core frontend features using TypeScript and Go.
• Drive user adoption by conducting interviews, reviewing PostHog sessions, and iterating on onboarding to make complex agent executions intuitive.
• Function as a full-stack owner, building features from backend infrastructure to polished landing pages and customer-facing tools.

The ideal candidate:

• Has 3+ years of experience shipping B2B products used by thousands of users with a strong portfolio of high-quality frontend work.
• Possesses incredible visual taste and Figma fluency, balancing perfectionism with the pragmatic need to ship rapidly in a startup environment.
• Demonstrates an AI-native mindset with the ability to manage customer accounts directly and translate feedback into high-impact platform improvements.

We never post fake jobs

This isn't a trick. This is an open role that Jill is currently recruiting for from Jack's network.

Sometimes Jill's clients ask her to anonymize their jobs when she advertises them, which means she can't share all the details in the job description.

We appreciate this can make them look a bit suspect, but there isn't much we can do about it.

Give Jack a spin! You could land this role. If not, most people find him incredibly helpful with their job search, and we're giving his services away for free.
