Mid-Level Backend Developer
About the role
🌱 Genki means "healthy, energetic, and full of spirit". That's us.
🚀 We're a fully remote, profitable startup of about 25 people, five years in and growing steadily.
🌍 We build tailored health insurance for long-term travelers like digital nomads, serving over 75,000 people in 200 countries.
💚 Our vision is to help them stay healthy wherever they go, far beyond insurance.
We're looking for a Mid-Level Backend Developer to help build and evolve the core system that powers our products and operations. You'll join as the second developer in our backend team, reporting to our Lead Backend Developer.
Our backend runs on Kotlin with a custom framework built around event sourcing. It's not yet fully documented, so you'll need to be comfortable reading code, asking questions, and finding your way through a system that's still being shaped. You'll build new features, improve testability and reliability, and help evolve the architecture over time.
The product is complex and spans multiple domains. You'll need to build deep understanding quickly and be comfortable making decisions with incomplete information.
We're moving fast, increasingly with AI-agentic development tools. You should have some hands-on experience with these tools and a genuine drive to go deeper.
Show us what you've got. Send us a link to your GitHub profile, code samples, prompts, a vibe-coded job application, or whatever expresses your experience best!
