🔹 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.

You’ll:

  • Deploy/manage VPN protocols (WireGuard, OpenVPN, IPSec) in production
  • 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.

🔹 How to Apply

Send an email to

with:

  • A short intro + relevant background
  • Examples of VPN infra you’ve deployed in production
  • GitHub/code samples (if available)
  • Hourly rate + availability
  • Confirmation that you’ve read the JD

Include the word ARCHITECT in your subject line or intro — applications without it will not be reviewed.
