Infrastructure Engineer (Network & Observability)

Location: Warsaw, Poland (City Centre, near Rondo ONZ) — Hybrid model (3 days a week in the office, 2 days remote)

Contract Type: Permanent (Umowa o Pracę)

About the Role & Project:

We are recruiting for our client – a rapidly growing, global financial institution operating in the capital markets. 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.
