About Mindsera

Mindsera is the world’s most advanced AI-powered journal for smarter insights. We help people think better by combining AI with journaling to create a smarter, more insightful self-reflection experience. We're a small, independent team. Since launching in 2023:

- 70k+ users journaling with us

- 100M+ words written

- Featured in Forbes, The New Yorker, a16z, and more

Things we care about

- Human-first AI. Most AI tools try to think for you. We use AI to help you think better. Your thoughts stay yours. We just help you see them more clearly.

- Small team, big output. We're not building a Navy. We're building Seal Team 6. Everyone here ships real work that users actually see.

- Excellence. Small details matter. We question everything. We design backwards from the best possible experience, not from what's standard.

- Genuine impact. We want to help people live better lives.

The role

This is a true full-stack role. You'll build backend logic, web UI, React Native mobile, and AI integrations. If you only want to work on one layer, this isn't the role.

What you'll do

- Own features end-to-end, from idea to production

- Ship weekly, sometimes daily

- Build AI features with LLM integrations and prompt engineering

- Refactor, optimize, and fix bugs across the stack

- Talk to users and dig into support to understand what's actually needed

Who we're looking for

- Sharp and fast. You pick up new tools and concepts quickly. When something breaks, you figure it out. When requirements are vague, you fill in the gaps with good judgment.

- AI-native. You use AI tools daily. You've built with LLMs. You have opinions about prompting, context windows, and model selection.

- Owners, not task-takers. You don't wait for detailed specs. You understand problems, propose solutions, and ship.

- Builders at heart. You'd be coding even if no one paid you. You have side projects.

Requirements

- Full-stack experience: backend (Node, Python, or similar) + frontend (React) + mobile (React Native or willing to learn fast) - You've built and shipped something from scratch. A side project, a startup, a feature you owned completely. - Experience integrating AI into products (not just using ChatGPT)

Nice to have

- Interest in psychology, mental health, or personal development - Eye for good design and basic Figma skills - Experience at early-stage startups

Details

- Remote (EU timezone preferred) - Part-time to start, full-time based on fit - Pay based on experience
