Job Description:

At Ledger, we’re proud to be the global platform for digital assets and Web3, with over 20% of the world’s crypto assets secured through our Ledger devices. If you are a final-year student in computer security or networks with a strong interest in Security with a particular interest in Zero Trust and infrastructure-level security, join Ledger for a six-month internship within the Cyber Security Engineering team to help design, test, and improve our ZTNA and Network Security Architecture. You will work closely with Security Engineering, Infrastructure/SRE, and Platform teams on production-grade environments for Ledger internal infrastructure.

Job Responsibility:

Work with Security Engineering and Infrastructure / SRE and IT teams to strengthen Ledger’s network and access security model
Map and document application and admin flows (who/what/where) and propose Zero Trust patterns (per-app access, identity-aware gateways, strong auth)
Contribute to PoCs and integrations for ZTNA / SASE / secure access solutions (e.g. controlled access to cloud consoles, internal admin tools, and critical SaaS)
Help define and document reference architectures, diagrams, and runbooks for secure remote access and network security
Where relevant, contribute small scripts/tools (Python, shell, etc.) to automate validation, configuration checks, or data collection.

Requirements:

Solid understanding of network fundamentals: TCP/IP, routing, DNS, VPN, HTTP(S), TLS
Good grasp of core security concepts: Zero Trust, least privilege, segmentation, identity- and context-based access
Comfortable with Linux environments and at least one scripting language (ideally Python) plus basic Git usage
Interest in cloud environments (AWS/GCP/Azure or similar) and modern access patterns (bastions, proxies, SASE/ZTNA)
Ability to read and challenge technical documentation and propose pragmatic improvements
Proactive, curious, and willing to dive into low-level technical details
Interest in Web3 and hardware wallets is a plus and provides useful context on Ledger’s ecosystem.
