🔹 About Us
We’re Quanta Tech Systems — an async-first startup building secure crypto exchange infrastructure. Small team, high-ownership culture, building fast without cutting corners.
🔹 The Role
We’re hiring a Backend Developer with experience in VPN infrastructure to help us architect and scale our foundational systems. This is not a maintenance role — you’ll be building core APIs, wallet systems, and secure VPN layers from scratch.

- Architect backend services for authentication, routing, and monitoring
- Build APIs for trading, P2P, wallet ops, deposits/withdrawals
- Collaborate with infra + product teams on compliance and resilience
- Write tested, modular code (PHP/Laravel primary; Go/Rust/Node.js welcome)
- Optimize across multi-region deployments (Docker/Kubernetes, CI/CD)
🔹 Requirements
- 2–4 years commercial backend experience (Laravel preferred)
- Hands-on production deployment of VPN infra (WireGuard/OpenVPN/IPSec)
- Strong SQL + networking/security knowledge
- Solid understanding of clean architecture & code principles
- Async-first work style (Slack, Notion, GDrive)
- Able to complete enhanced background checks for compliance
🔹 Nice to Have
- Crypto/fintech platform or exchange experience
- Blockchain node integration (Infura, Alchemy, self-hosted)
- Monitoring experience (Grafana, Prometheus, Zabbix)
- Fluent Ukrainian/Russian or strong English
🔹 Compensation
Competitive hourly contractor role — aligned with Eastern Europe market rates and experience level.
