• 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. • 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. • 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.

• Own the technical direction of all our internal and public web projects • Unify what's grown organically and build the foundation for what comes next • Work as the sole web engineer and grow a team over time • Collaborate closely with a designer to shape what we build and how it looks • Build a setup where team members from all departments can build software themselves, with standardized review, security, and deployment

Role Description 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. - 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! Qualifications - You've worked on larger backend systems in production and understand the complexity they bring. - You've worked in complex product domains and can ramp up quickly on business logic that isn't always obvious. - You're comfortable with event sourcing, event-driven architecture, or similar patterns. - You care about code quality: readable code, meaningful tests, and clean APIs. - You have some experience with AI-agentic development tools (Claude Code, Codex, or similar) and want to go deeper. Requirements - Language: Kotlin with coroutines - Framework: Custom, built around event sourcing - Billing: Stripe - Infrastructure: Heroku (migrating to Railway) - AI-agentic development: Claude Code with custom plugin - APIs: GraphQL Benefits - Up to 5,000 EUR/month (depending on experience) with employee equity participation through a vesting program - Fully remote, from anywhere in the world & live as a digital nomad if you want to - Flexible hours, startup atmosphere - Most of the team is in Europe and Southeast Asia, with a few hours of daily overlap around German business hours - Company-issued and managed MacBook, plus a desk in your favorite co-working space - 25 days paid annual leave - Regular team off-sites to connect in person

We need someone who: - Builds carefully and ships fast. - Understands the importance of security, reliability, and maintainability. - Uses AI agents to build better software, faster. - Creates a setup where team members from all departments can build software themselves. - Ensures standardized review, security, and deployment for safe shipping. 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! Qualifications - Built and shipped production web applications end-to-end, from static sites to complex SPAs. - Made major architectural bets and learned from them. - Proven experience with cross-project infrastructure: shared component libraries, CI/CD pipelines, monorepo setups, deployment automation. - Strong understanding of web security, performance optimization, and browser capabilities. - Sharp eye for detail, from pixel-perfect implementation to clean, consistent code. - Daily use of AI-agentic development tools (Claude Code, Codex, or similar) and effective steering of their output. - Set up and maintained CI/CD, testing strategies, and developer tooling for teams. Requirements - Languages & frameworks: TypeScript, React, React Router, Next.js (being phased out), SCSS Modules, Astro. - Bundling: Vite. - Design: Figma. - AI-agentic development: Claude Code with custom plugin (open to exploring alternatives). - Infrastructure: Cloudflare, Railway. - APIs: GraphQL.
