Senior React Full-stack Developer

Lemon.io

Remote

You've built projects, shipped code, and want to work on your own terms. Lemon.io connects developers directly with startups that need your skills — and they handle the rest. No client hunting, no rate negotiations, no time trackers. You focus on engineering.

As a Senior React Full-stack Developer, you'll work on real products for US and European startups. You communicate directly with clients who understand code. Your schedule is yours: async work, minimal overlap, or whatever rhythm works. You'll get projects matched to your skills and preferences, not assigned randomly.

This fits you if you have solid React experience, a portfolio you're proud of, and want remote work that respects your seniority. Computer science background helps, but solid self-taught developers with proven projects work too. Lemon.io has already paid out over $11M to engineers on their platform — rates depend on your skills and experience.
