System Administrator

Fintech Synergy
Posted 8 hours ago
🇵🇹Portugal🏠Remote📁Engineering & Development
Is this job info correct?

FinTech Synergy is looking for a System Administrator to help us maintain, develop, and continuously improve the infrastructure behind our company and products.


(!) only for RUSS OR UKR language speakers (!)


We build complex IT and FinTech solutions, including payment systems, financial platforms, Crypto/Web3 products, and other high-load systems.


We’re looking for an experienced and highly independent professional who doesn’t just resolve tickets, but sees infrastructure as a complete system, identifies weak points, automates routine operations, and takes ownership of the result.


Key Responsibilities

  • Administer and maintain servers and infrastructure
  • Ensure system stability, availability, performance, and security
  • Configure and maintain networking infrastructure, VPNs, DNS, firewalls, and access controls
  • Work with Docker and containerized environments
  • Administer cloud and virtualized infrastructure
  • Set up and maintain monitoring, logging, and alerting systems
  • Manage backup and disaster recovery processes
  • Manage users, roles, permissions, SSH keys, and infrastructure access
  • Troubleshoot complex infrastructure and network incidents and perform root cause analysis
  • Collaborate closely with DevOps, Developers, QA Engineers, and other members of the technical team


What We’re Looking For

  • 2+ years of experience in System Administration / Infrastructure
  • Deep understanding of networking: TCP/IP, DNS, HTTP/HTTPS, VPN, routing, firewalls
  • Practical experience with Docker
  • Experience with AWS, GCP, Azure, or other cloud infrastructure
  • Strong understanding of information security and infrastructure hardening
  • Experience with monitoring and logging solutions
  • Understanding of CI/CD and modern software development lifecycle
  • Ability to independently investigate and solve complex technical problems
  • English sufficient for working with technical documentation


Who Will Fit Our Team

Technical expertise is important, but mindset matters just as much.

We’re looking for someone with a strong sense of ownership and responsibility - a person who doesn’t need detailed instructions to act, can identify problems independently, propose solutions, and drive them through to completion.


Our culture provides a lot of freedom - and with that freedom comes a high level of responsibility for quality and deadlines.


What We Offer

  • 100% remote work
  • Flexible working hours
  • No micromanagement
  • No time trackers
  • Freedom to influence technical and infrastructure decisions
  • Complex and challenging FinTech & IT products
  • AI-oriented environment and openness to new technologies
  • A strong team of experienced professionals
  • Opportunity to grow professionally together with the company
  • 22 paid working days off
  • Official employment in Portugal


FinTech Synergy is about freedom in how you work - and ownership of the result.
