About Sybilla Technologies📡

Sybilla Technologies designs, builds, and operates robotic optical observatories for monitoring objects in space. We specialize in end-to-end systems and software for automated data acquisition, analysis, and scheduling across networks of sensors.

Our work spans Space Situational Awareness, Space Surveillance & Tracking, Space Traffic Management, as well as stellar and planetary research, education, and commercial on-demand observations. By combining cutting-edge technology with advanced software, we enable faster, smarter, and more reliable insights from space.

Your responsibilities:

1. Keeping the company online and secure

  • Ensuring high availability and security of core IT services, including network connectivity, VPNs, DNS, identity systems, email, and access to internal resources.
  • Taking ownership of uptime and service reliability - spotting issues early and preventing outages rather than reacting to them.
  • Designing and maintaining monitoring that provides actionable signals.

2. Microsoft 365 & Azure administration

  • Operating and continuously improving the Microsoft 365 and Azure environment (identity, access, security, resource lifecycle).
  • Managing cloud resources with attention to structure, ownership, and cost hygiene.
  • Maintaining a least-privilege access model using RBAC, Conditional Access, and MFA.
  • Handling Exchange Online mail flow, spam and anti-phishing protections, and complex deliverability issues.

3. Networking and remote access

  • Administering network infrastructure based on MikroTik (routing, switching, VLAN segmentation).
  • Configuring and maintaining VPN connectivity (site-to-site and remote access, including WireGuard).
  • Troubleshooting issues across network, identity, device, and service layers.

4. On-prem infrastructure and virtualization

  • Maintaining Hyper-V environments on Windows Server.
  • Administering Linux servers (Ubuntu) and containerized workloads.
  • Managing storage systems, including HA storage, QNAP platforms, iSCSI, and shared storage architectures.

5. Backup and disaster recovery

  • Ensuring reliable backups using Veeam: retention policies, encryption, access controls, and restore testing.
  • Regular verifications that systems can be recovered, not just backed up.
  • Thinking proactively about disaster recovery scenarios and operational resilience.

6. Hardware and physical infrastructure

  • Managing hardware lifecycle: servers, network cards, UPS, firmware updates, and diagnostics.
  • Monitoring hardware health, including Supermicro platforms and out-of-band access.
  • Coordinating repairs, replacements, and RMA processes.
  • Working hands-on with server rooms and rack infrastructure when needed.

7. Locations and environments

  • Providing remote support for infrastructure located in a colocation facility in Toruń and a secondary/DR site in Zielonka/Bydgoszcz, along with distributed and remote endpoints.

Terms & Benefits:

  • Remote work model (HQ in Bydgoszcz/Zielonka).
  • Compensation: 15,000-17,000 gross PLN/month (UoP) or 116-132 PLN/hour net (B2B), depending on experience and skills.
  • Work in a rapidly growing company within the prestigious Space industry.
  • Full-time position with flexible working hours.
  • Private medical care (LuxMed) and sports package (Multisport).
  • Structured onboarding with dedicated support during the first weeks.
