Part III — For Builders
Join Us
For the builders who want to make tools that matter.
What We're Building
brain.bike is a suite of integrated tools to help people think better, learn faster, and achieve more.
Four products. One system. A bicycle for the mind.
If you've ever felt like your productivity tools are fighting each other instead of helping you—if you've wished your notes would become flashcards, your goals would become tasks, your tasks would remind you at the right moment—that's what we're fixing.
Why This Matters
We spend our lives in tools that fragment our attention, forget our context, and wait passively for us to remember they exist.
We think software can be better. We think AI makes it possible to build tools that actually help—that remove friction, connect dots, and bring your attention back to what matters.
We're not building another to-do app. We're building cognitive infrastructure.
What It's Like Here
The Work
- Small team, big problems. You'll own entire features, not tickets.
- Ship fast, learn faster. We're in beta mode. Iteration speed is everything.
- Quality matters. Fast doesn't mean sloppy. We care about craft.
The Culture
- Deep work is sacred. Minimal meetings. Async by default.
- Opinions are expected. We hire people who think. Disagree with us. Push back. Be right.
- Users are everything. We talk to them constantly. We use our own tools daily.
The Environment
Who We're Looking For
We're hiring across:
Engineering
- Full-stack (React/Node or similar)
- AI/ML (LLM integration, prompt engineering)
- Systems (performance, infrastructure)
Design
- Product design (UX + visual)
- Brand and marketing design
Product
- Product management
- User research
What We Value
- Builders over talkers. Show us what you've made.
- Curious over credentialed. We don't care where you went to school. We care what you've learned.
- Opinionated over agreeable. Bring strong views, loosely held.
- Fast learners. We're building in new territory. Adaptability > expertise.
The Pitch
If you want to work on something that matters—tools that help humans be more human, not less—we should talk.
We're early. It's hard. The upside is huge.
We're building a bicycle for the mind.
Come ride with us.
Send us what you've built, what you're thinking about, and why this resonates.
