Technical Founder AI Pet Adoption

  2026-05-21     Stealth Startup     Santa Rosa,CA  
Description:

We're an consumer startup already serving hundreds of thousands of users across multiple markets.

The product is live. Users are there. Revenue is there. Growth is there.

Now the challenge is execution:

Building a product experience people love, scaling fast, and creating a category-defining company.

We're looking for a founding engineer who wants to build something ambitious.

The role

This is not a “ticket execution” role.

You'll work directly with the founder on:

  • product strategy,
  • UX,
  • growth,
  • monetization,
  • infrastructure,
  • AI features,
  • and company direction overall.

You should think like an owner, not an employee.

We want someone who:

  • cares deeply about user behavior,
  • obsesses over product quality,
  • moves extremely fast,
  • and wants to help build a very large company over the next 5–10 years.
What matters most

The hardest problems are not purely technical.

They're questions like:

  • Why do users drop?
  • Why do they trust us?
  • What makes them emotionally engaged?
  • What creates retention?
  • What turns a product into a habit?
  • How do we create a best-in-class mobile experience?
  • How do we turn distribution into a durable company?

We care a lot about:

  • UX,
  • conversion,
  • speed,
  • product instinct,
  • and founder mentality.
What you'll work on
  • Improving key user journeys
  • Increasing conversion rates
  • Building delightful mobile experiences
  • Creating AI-powered user features
  • Scaling backend infrastructure
  • Shipping experiments fast
  • Building monetization systems
  • Improving retention and engagement
  • Working directly from analytics and user feedback

You'll have real ownership from day one.

Stack
  • Next.js
  • TypeScript
  • Node.js
  • MongoDB
  • AWS
  • Stripe
  • OpenAI APIs
You're likely a fit if…
  • You've built products from 0→1
  • You think product first, not just code first
  • You care about details users notice
  • You're highly autonomous
  • You move fast
  • You're ambitious
  • You want to build something meaningful at scale
  • You enjoy being close to strategy, growth and product decisions

Bonus:

  • consumer startup experience
  • marketplace experience
  • AI product experience
  • strong design/UX intuition
  • growth mindset
Not a fit if…
  • You need lots of structure/process
  • You only want a narrow engineering scope
  • You optimize for comfort over ambition
  • You prefer maintaining systems instead of building
Compensation

Flexible depending on profile:

  • salary + equity
To apply

Send:

  • products/features you built,
  • examples of UX or conversion improvements you shipped,
  • GitHub/portfolio,
  • and a few lines on the biggest consumer product opportunity you see today.

No generic applications.
