Network Engineer – Crypto Trading Infrastructure

RAVEN; Milano; In loco; EUR 90.000 - 120.000; Tempo pieno

Descrizione del lavoro

Raven is a crypto market-making and high-frequency trading firm seeking an infrastructure-focused engineer. You will work on a latency-critical trading network across multiple regions, owning automation, DNS, firewalls, and server provisioning.

The role is office-based in Milan or Sofia, with no remote option, and requires strong Linux, scripting, and networking skills along with a proactive learning mindset.

Competenze

• Working knowledge of Linux - shell, services, filesystems, permissions, and reading logs when something breaks
• Enough scripting to automate anything you would otherwise repeat, and the patience to read code and config you did not write
• The networking basics - IP/CIDR, subnets, routing tables, TCP versus UDP, DNS, TLS, and firewalls - plus curiosity about the layers underneath
• Enough packet-capture literacy to tell "the request never left" from "we got no reply"
• Some hands-on time with a cloud platform, even if only on your own projects
• Evidence you teach yourself hard things, whether a home lab, a personal project, or a competitive result you are proud of
• Care and humility around production systems. You verify rather than assume, read before you write, and ask early rather than guess
• Fluent English. It is the working language across both offices

Mansioni

• Change infrastructure as code across estate, review plans and prevent drift
• Manage DNS, firewall rules, SSH access using a single source of truth
• Operate automation routing traffic between private circuits and cloud peering
• Run latency and reachability checks against RTT targets; capture packets when needed
• Linux tuning at bootstrap, kernel parameters, NIC settings, CPU pinning, repeatable scripts
• Improve bootstrap, monitoring, and blockchain-node scripts; maintain runbooks
