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

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.

Our Mission and Vision
 

At Solidgate, our mission is clear: to empower outstanding entrepreneurs to build exceptional internet companies. We exist to fuel the builders — the ones shaping the digital economy — with the financial infrastructure they deserve. To achieve that, we’re on a bold path: to become the #1 payments orchestration platform in the world.
 

About the Team and Role
 

As a Node.js Engineer in the Launch Team, you’ll power the backend behind the Digital Onboarding. Our mission is to ensure Solidgate works with compliant merchants while making the onboarding experience fast, seamless, and scalable.
 

You will build the fastest path from “I’m interested” to “I’m live.”
 

Why it’s different

• You’ll reduce Time-to-Live — directly impacting growth.
• You’ll shape the evolving Node.js stack (no legacy drag).
• You’ll design resilient, durable and scalable systems targeting 99.99% uptime.
• You’ll use AI to ship faster and embed AI-powered features into the product.
   

Tech Stack

Launch is one of the first teams driving the Node.js stack at Solidgate.
 

We don’t just adopt tools — we define standards, practices, and engineering culture that other teams follow. What we use:

• Fastify — lightweight, high-performance web server
• gRPC + Protobuf — typed service-to-service communication
• PostgreSQL + Drizzle ORM — reliable data layer with a modern query builder
• Kafka (@platformatic/kafka) — streaming-first, event-driven architecture
• Vitest — unit and functional testing

Plus custom solutions: distributed locks, metrics, streamers, and more.

Explore our full technology stack ➡️ here (https://solidgate-tech.github.io/)

The stack is still evolving — meaning real influence. No legacy baggage. Just modern Node.js running on mature architectural rails inspired by the Golang ecosystem.
 

What you’ll be doing

• Designing a flexible compliance rule engine. You’ll help design a rule engine capable of supporting multiple regulatory frameworks while remaining flexible and easy to adapt as policies change. The system should also be able to detect when rule updates require re-evaluating previously approved merchants and trigger the appropriate compliance workflows.
• Building systems with full traceability. We operate on highly sensitive compliance data, where transparency and accountability are essential. You’ll build systems that provide end-to-end auditability, ensuring every action can be traced.
• Ensuring reliability of mission-critical services. The data produced by this platform powers multiple downstream systems, including financial settlement processes and banking integrations used to open MIDs for merchants. You’ll work on building services that are highly available, durable, and resilient, ensuring the reliability of critical business operations.
• Leveraging AI for smarter document processing. You’ll help introduce GenAI-powered capabilities to streamline document processing and verification flows, reducing manual work for compliance teams and significantly accelerating merchant onboarding.
   

Who you are

• Strong ownership and clear tech POV.
• You ship production-ready systems, not just features.
• 2+ years of Node.js backend experience with solid TypeScript skills.
• Confident with testing (unit/integration/e2e).
• Comfortable with distributed systems principles.
   

Nice to have: GenAI, Next.js, compliance-heavy domains (GDPR/SOC2), Golang experience.

Senior Full-Stack Engineer (Backend-Oriented, Node.js)

Build the real-time AI governance control plane trusted by global enterprises

Who We Are

Adaptiq is a technology hub specializing in building, scaling, and supporting R&D teams for high-end, fast-growing product companies across a wide range of industries.

About the Product

You’ll work on a cloud-native AI governance platform designed to intercept, classify, and control high-velocity AI interactions in real time — without revealing the client’s identity.

The platform processes user prompts, model responses, coding-agent activity, and enterprise search operations across HTTP streams, IDE extensions, LLM APIs, and internal microservices. It applies need-to-know access filters, transformations, and audit controls within milliseconds, ensuring sensitive information never crosses boundaries it shouldn’t.

As enterprises adopt generative AI at scale, traditional access-control models break down. This platform introduces a new security layer purpose-built for AI systems, enabling organizations to innovate quickly while maintaining strict governance over their data and models. You’ll join a core engineering team building a system with real industry impact — one shaping how AI responsibly integrates into the modern enterprise.

About the Role

We’re looking for a Senior Full-Stack Engineer (Backend-focused) to join a small, high-caliber engineering team developing the core components of this real-time governance platform.

• 4+ years of hands-on experience with Node.js and TypeScript
• Working knowledge of React and modern frontend development
• Understanding of backend architecture, APIs, and service-oriented design
• Experience with relational databases (PostgreSQL or similar)
• Experience with containerized and cloud-native environments
• System understanding and experience participating in architecture discussions
• Strong communication skills and ability to collaborate in a distributed team
• Ability to operate in a dynamic, fast-paced product environment
• Excellent English communication skills (written and spoken)

Nice to Have

• Experience with CI/CD pipelines (GitHub Actions or similar)
• Experience with Python and/or Go
• Production experience with TypeScript-based backend systems
• Exposure to LLM/AI applications (LLM APIs, vector DBs, orchestration frameworks)
• Experience integrating ML/AI models into production
• Background in B2B or security-focused products
• BSc in Computer Science or related field
  
   

Why Us

• 20 days of annual vacation + official national holidays
