BlockTech is a fast-paced algorithmic trading firm facilitating global cryptocurrency trading while expanding into regulated markets.

• Work closely with our traders, engineers and quantitative developers to identify and solve issues that arise

• Plan, deploy, and maintain L2/L3 networking components in LAN/WAN/cloud environments.

• Troubleshoot and resolve network performance and connectivity issues.

• Implement and monitor routing protocols (e.g., OSPF, BGP), VLANs, VPNs, and firewalls.

• Develop and maintain scripts/tools (Python, Ansible, Terraform, etc.) for network provisioning, configuration, monitoring, and alerting.

• Build CI/CD pipelines for network infrastructure (Infrastructure as Code - IaC).

• Automate repetitive tasks and develop self-healing solutions.

What is in it for you?

• A full-time position in a relaxed and modern office in Amsterdam

• Competitive compensation consisting of a base salary combined with a very attractive bonus plan based on individual and company performance
