About the role

The Role

This is a founding product engineer role. You'll own big chunks of the product. Not take tickets from a backlog. The work is broad by design. In any given week you'll be:

  • Shipping new product features end-to-end: designing the UX, building it, shipping it
  • Improving the product based on user feedback
  • Building and refining AI pipelines: prompt engineering, eval systems, handling non-deterministic outputs
  • Building email lifecycle flows to drive activation and retention
  • Analyzing our funnels and forming product hypotheses
  • Fixing whatever's broken that day
  • Building internal tooling and dashboards
  • Spinning up a micro-tool that could go viral on X

The common thread isn't a specific technology. It's range. We need someone who can context-switch across product, engineering, AI, growth, and analytics without losing momentum.

You

  • You're a true generalist. Frontend, backend, AI engineering, growth experiments, product, design, analytics. You can pick up anything and run with it.
  • You have real product sense. If I say “the edit UX sucks, figure out a better approach,” you ship something good without needing a Figma mock.
  • You build with AI tools natively. Claude Code, MCPs, Skills, Agents, whatever's latest. They're part of how you work every day. You're not just using AI. You're obsessed with optimizing your setup to maximize output.
  • You're autonomous. You intuitively know the highest-leverage thing to work on, and you just go do it. You don't need to validate every decision. You have the judgment to run with it and the taste to get it right.
  • You ship a ton. You can hold multiple threads in your head, context-switch without losing momentum, and maintain quality at speed. Look at my commit graph - that's the pace. But speed without quality is just slop. Clean code, proper PRs, strong fundamentals.
  • You're hungry. Startups, shipping fast, building things people actually use. This is what gets you up in the morning.
  • You're in SF or willing to relocate. This is in-person. If you need visa support, we can help make it happen.

Why Bloom

  • Real traction. This isn't a speculative idea. We have paying customers, strong MRR growth, and a product people love.
  • Massive ownership. You're engineer #2 at a company with clear product-market fit signal. The surface area you'll own is enormous.
  • The space is on fire. AI + creative tools is one of the most exciting areas to build in right now. And we're already winning in it.
  • It's a beautiful product. Bloom has a strong brand, a strong community, and a team that's proud of it. If you care about building something you're proud to show people, this is it.
  • It actually matters. Good design is inaccessible for most businesses. So their marketing looks generic. Templates, AI slop, off-brand noise. Bloom gives every business the ability to look like themselves at scale. More beauty, less slop. That's a world worth building.
