Hello.

We are looking for a Middle+/Senior Node.js Developer to join Ohayu (https://ohayu.com). We are building the easiest way for travelers to stay online anywhere in the world. We’re a fast-scaling B2C mobile + web app (iOS/Android/Web) that lets people buy eSIM data plans in minutes - cheaper than roaming, no SIM shops, no hassle. Thousands of travelers already use Ohayu worldwide, and we’re just getting started.
Our ambition is bigger than eSIM: we’re evolving Ohayu into a full Travel App that makes every journey smoother.

What you’ll do:

This role is for someone who wants real ownership and real product impact.

• Own integrations with third-party APIs (telco/eSIM providers, payments, analytics, etc.) - abstraction layers, reliability, observability, edge cases, scale.
• Shape backend direction: architecture decisions, technical standards, and how we build/ship safely at speed.
• Enable rapid experimentation: implement backend changes for A/B tests and product iterations that directly impact conversion and retention.
• Build and maintain production-grade services: migrations, logging, alerts, uptime, and smooth releases.

What we’re looking for:

• 5+ years of backend with OOP experience
• 5+ years with Node.js + TypeScript
• 2+ years with NestJS
• 5+ years with MySQL / MariaDB / PostgreSQL
• Hands-on production experience: migrations, monitoring/logging, alerts, process managers (pm2/supervisor), incident mindset
• You work independently, communicate clearly, and take responsibility end-to-end
• At least intermediate English level (all work communication is in English)

Nice to have:

• Experience with high-load systems
• Experience supporting A/B testing and experimentation platforms/pipelines

Why to join us:

• Direct product impact: what you ship gets used immediately by real travelers.
• Ownership: you’re not “a contributor,” you’re a builder helping set the backend direction.
• Product engineering culture: we care about UX and conversion as much as we care about clean code.
• Fast pace, real learning: constant iterations, clear feedback loops, real-world constraints.
• Genesis ecosystem: access to strong expertise, resources, and networking.
• Benefits: health insurance, 20 paid vacation days, annual performance review with clear salary progression.

Work format: Possibility to work fully remotely or from our offices in Warsaw, Kyiv or Lviv.

Join us in reshaping the future of connectivity.
