Low-Latency Network Engineer

We are looking for a skilled and driven Network Engineer to lead the design and operation of high-performance, ultra-low-latency network links, including those based on radio frequency and optical technologies. This role is critical to achieving the fastest possible data delivery across long-distance infrastructure and requires close collaboration with RF vendors and international teams. If you are passionate about high-performance networks, eager to work on cutting-edge latency-sensitive systems, and thrive in a global environment—we’d love to hear from you.

Responsibilities

• Design, plan, and maintain high-performance RF-based and optical links with a focus on ultra-low latency.
• Collaborate with RF vendors and partners to manage link deployment and lifecycle.
• Proactively monitor network performance, implement metrics, alerting, and telemetry for end-to-end visibility.
• Contribute to network documentation, capacity, and resource planning.
• Maintain and expand the infrastructure inventory (~150 network devices and 1000+ servers).
• Participate in automation of operational tasks and configuration management.
• Ensure the fastest possible data delivery with reliability guarantees.

Requirements

• Proven experience in building or operating low-latency networks, ideally in trading, finance, or similarly latency-sensitive environments.
• Strong knowledge of RF technologies, including SDR, LOS validation, link budgeting, and spectrum planning.
• Ability to engage with RF vendors and partners to ensure robust link design and performance.
• Familiarity with submarine cable infrastructure, including CLS operations, optical lambdas, and provisioning workflows.
• Experience with low-latency networking hardware, including Layer 1 switches and optical transport.
• Proficiency in diagnosing network issues and conducting incident response in distributed environments.
• Knowledge of network automation tools such as Ansible, Python, NetBox, or similar.
• Familiarity with observability stacks like Grafana, Prometheus, and other telemetry tools.
• Ability to plan and manage network capacity, including forecasting and optimization.
• Advanced written and spoken English.
• Willingness to travel internationally and collaborate across time zones.

What we offer

• Competitive compensation above the market with bonuses twice a year up to 50% of annual salary.
• Sophisticated internal training and development programs.
• Comprehensive health insurance.
• Reimbursement for sports activities.
• Engaging in corporate events twice a year.
• High level of influence and ownership of the process.
