DevOps Engineer · Mid-Senior · Infra (Tesonet Global, UAB)

Job description:
At NordLayer, we’re building cybersecurity that scales with the business.
A toggle-ready platform that helps modern teams thrive-without the security headaches. Trusted by 11,000+ global companies, NordLayer plugs into any tech stack and protects users across borders.
Your impact? Helping businesses stay protected and moving forward with future-ready network security.
We're looking for a DevOps Engineer to join our SRE team who's just as comfortable debugging a kernel-level networking issue as writing a clean Terraform module - someone who wants to help evolve real infrastructure at scale, not maintain a green-field lab.
Design, build, and maintain hybrid infrastructure spanning our on-prem bare-metal fleet and AWS cloud environment;
Build and evolve Infrastructure-as-Code (Terraform and Terragrunt) and configuration management (Puppet/Ansible) across both environments;
Maintain and improve the platform's network stack - routing, load balancing, tunneling, and security features;
Build and maintain CI/CD pipelines (GitLab CI) supporting infrastructure and platform delivery;
Participate in incident response and contribute to postmortems, helping improve reliability practices over time;
Explore and apply AI tools to reduce toil and improve automation, tooling, and incident response across the team;
Collaborate cross-functionally with Product and other engineering teams to translate business needs into infrastructure solutions;
Bring your own ideas - this team wants engineers who improve how we work, not just execute a backlog.
Requirements:
3+ years of hands-on Linux systems/infrastructure experience;
Solid understanding of networking fundamentals (IPv4, routing, bridging, proxies, DNS);
Practical, production experience with AWS
Experience with Infrastructure as Code (Terraform);
CI/CD pipeline experience (GitLab CI preferred);
Comfortable scripting (Bash and Python) to automate operational work.
Genuine enthusiasm for AI tools and workflows, with hands-on experience applying them to real infrastructure work (e.g. automation, incident response, tooling).
Nice to have
Experience writing and maintaining reusable Terraform modules;
Configuration management experience with Puppet and/or Ansible;
Experience with unix network tools and tunneling protocols (iptables, nftables, OpenVPN, IPSec, WireGuard, Bind/PowerDNS);
Applied cybersecurity principles (least privilege, defense in depth, secrets management).
Experience with container/virtualization environments (Docker, LXC, microVMs, ECS);
AWS certification (SysOps Administrator or Solutions Architect Associate);
Experience with Terragrunt.
