Infrastructure Engineer (Network & Observability)

About the Role & Project

We are looking for an engineer eager to bridge the gap between traditional network engineering and modern DevOps practices.

This is not a role for a traditional network administrator. We are seeking a specialist whose default approach to repetitive tasks is automation, and who is passionate about building advanced telemetry and monitoring systems. Your mission will be to transform a global, high-availability infrastructure into a self-service, highly observable platform.

If you thrive in environments where system stability and milliseconds directly impact business outcomes, and where manual intervention is treated as a problem to be solved with code, this is the team for you.

Key Responsibilities

• Design, implement, and maintain advanced telemetry, monitoring, and predictive alerting systems for a global, high-availability network.
• Develop, scale, and maintain automation tools to streamline network workflows, from automated provisioning to zero-touch deployments.
• Collaborate closely with engineering and investment teams to align network performance with dynamic business and trading requirements.
• Define, implement, and maintain configuration standards across a robust multi-vendor environment.
• Serve as the senior escalation point for troubleshooting and resolving complex performance and routing anomalies.
• Participate in a 24/7 on-call rotation and scheduled out-of-hours maintenance windows.

Technical Profile (Technical Fit)

• Observability-First Mindset: Practical experience with modern monitoring stacks, telemetry protocols, and metrics collection (Prometheus, Grafana, Telegraf, gNMI, YANG, Cisco Telemetry).
• Automation as a Standard: Strong hands-on experience with automation tools and frameworks such as Ansible, Jinja, Terraform, Netbox, and workflow engines (e.g., Temporal).
• Infrastructure as Code (IaC) & Dev Skills: Proficiency in Python and Git, with experience managing network configurations programmatically (NETCONF/RESTCONF).
• Core Networking Foundations: Solid understanding of routing protocols and multicast environments (BGP, OSPF, PIM, IGMP).
• Public Cloud Integration: Practical knowledge of building and managing cloud network infrastructure (AWS).
• Advanced Troubleshooting: Ability to perform deep-packet analysis and diagnose complex, transient network issues under pressure.

Personal Attributes (Cultural Fit)

• A continuous learning mindset with a drive to proactively identify and optimize inefficient processes.
• Ability to work independently, taking ownership of projects and delivering them on schedule with minimal supervision.
• Excellent communication and collaboration skills, comfortable working in a fast-paced, international team.
• Strong analytical thinking and decision-making skills under pressure.

Bonus Points

• Experience integrating enterprise-grade VoIP and cloud collaboration systems.
• Familiarity with network security, identity management, and segmentation solutions (e.g., Cisco ISE).
• A basic understanding of financial markets, trading lifecycles, or quantitative trading environments.

What We Offer

• Stable Employment: Full-time employment contract (Umowa o Pracę - UoP).
• Tax Optimization: Eligibility for creative tax-deductible costs (KUP - Koszty Uzyskania Przychodu).
• Financial Reward: Highly competitive base salary accompanied by a generous annual performance bonus.
• Comprehensive Health: Premium private medical care package that fully includes dental coverage (stomatologia).
• Wellness & Lifestyle: MultiSport card to keep you active and healthy.
• Daily Perks: Pre-funded lunch card for your daily meals.
