Senior Network Engineer

Join a global enterprise team dedicated to shaping the future of international IT infrastructure. In this high-impact role, you will bridge the gap between high-level architectural design and robust security engineering across global LAN, WAN, SD-WAN, WLAN, and network security domains.

Rather than focusing on routine operational handling, you will take ownership of High-Level (HLD) and Low-Level Designs (LLD), drive continuous infrastructure optimization, and solve complex, high-tier technical challenges. You will act as a Subject Matter Expert (SME), partnering with our Managed Service Provider (MSP) and cross-functional international teams to deliver resilient, high-performing networks.

What you can expect from us?

• Contract: Long-term Employment Contract (Umowa o pracę).
• Bonuses: Annual performance bonus (up to 7%) + festive financial benefits paid twice a year (April & December).
• Health & Security: Comprehensive private medical care (Medicover, with options for family coverage) and group life insurance.
• Professional Growth: Full coverage of training courses and professional certification exams (e.g., Fortinet).
• Perks & Wellbeing: Sports card (Medicover Sport), language courses, flexible working hours, and regular team wellbeing activities.
