Senior Engineer (React/Next.js/React Native/Node.js)
We’re looking for a Senior Full-Stack Engineer to join a B2B SaaS platform with a mobile-first experience and a distributed backend architecture, where performance, data processing, and scalability are critical to the product’s success.
This is a great opportunity to work on a complex, real-world product used across multiple regions, contributing not only with code but also with technical decisions and product evolution.
What you’ll do
Design and build scalable features across frontend, mobile, and backend layers
Contribute to architectural decisions and system design
Work closely with product and engineering stakeholders
Optimize performance and data-intensive workflows
Collaborate within a distributed team, bringing a proactive and ownership-driven mindset
Tech Stack
You’ll be working with a modern, distributed stack:
Frontend: React, Next.js, React Native (Expo)
Backend: Node.js (Bun), GraphQL, REST
Database: MongoDB (complex modeling, read-heavy workloads)
Infrastructure: Google Cloud Platform (GCP), Docker, Kubernetes
Infrastructure as Code: Terraform, Ansible
Messaging: NATS
CI/CD: Jenkins + GitHub
Testing: Unit, Integration, End-to-End (Playwright)
What we’re looking for
Strong experience as a Full-Stack Engineer in modern web/mobile environments
Solid understanding of scalable systems and distributed architectures
Product-oriented mindset and ability to navigate complex systems
Proactive, autonomous, and comfortable taking ownership
Strong communication and collaboration skills in remote environments
Advanced English is required, as you’ll work directly with US-based clients in a fully collaborative environment.
✨ What we offer
20 days of paid time off per year
Flexible working hours (we care about results, not clocking in)
Remote-first culture
Health insurance + fitness benefit
Learning & development support
In-company English classes
Internal knowledge-sharing sessions
A collaborative, friendly, and human-centered team environment
