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.

Main Responsibilities

• 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.

Core 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 (e.g. EC2, VPC, IAM, RDS, ECS);

• 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).

Bonus Points For

• 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, Kubernetes, LXC, microVMs, ECS);

• AWS certification (SysOps Administrator or Solutions Architect Associate);

• Experience with Terragrunt.

Tools You Will Use

• Python

• Bash

• Linux

• Puppet

• Ansible

• Terraform

• Terragrunt

• AWS (EC2, RDS, ECS, VPC, IAM)

• GitLab/GitLab CI

• HashiCorp Vault and Consul.

What We Offer

• Sharpen your edge: training, mentorship, and room to grow — always.

• Take the time you need: extra vacation days, sick days, and time off when life calls.

• Get premium healthcare: private health insurance in Lithuania and Poland — fully covered.

• Protect your peace: enjoy free subscriptions to Calm, Headspace, and Mindletic, and our own resilience and mindfulness trainings.

• Own your fitness: in-house gyms, sport cards, online workouts, and personal guidance — on us.

• Pack your bags for workation: experience our company-wide trip abroad to the fullest.

• Work from anywhere: work from wherever keeps you in the zone.

• Celebrate your milestones: birthdays, weddings, and new family members — all deserve a gift.

• Parent with ease: children’s summer camps and flexibility around the schedule — because parenting never pauses.

• Join the party: team building and company events people talk about for months.

• Unlock Cyber City: coffee bar, open gyms, kids’ room, music room, massage chairs — our Vilnius HQ is yours to enjoy.
