Want to take ownership of large-scale infrastructure, solve complex technical challenges, and shape the future of our platforms?
Join Hornetsecurity's Service Reliability (SR) team and help power cybersecurity services used by customers worldwide. Our infrastructure processes over 200 million emails and scans more than 100 million websites every day, running on 4,000+ servers and 300+ Kubernetes nodes.
As we continue to grow and evolve following Vade's integration into Hornetsecurity and Hornetsecurity's acquisition by Proofpoint, you'll have the opportunity to modernize business-critical systems, build new platforms, and influence technical decisions in a complex, high-availability environment.
This isn't just about keeping systems running. You'll take end-to-end ownership of platforms, from architecture and automation to production operations and continuous improvement.
Your Job
Own and shape platforms: Design, build, and operate reliable, scalable infrastructure for our internal product teams, taking technical ownership from initial requirements to production.
Drive architecture and modernization: Make key technical decisions, improve existing systems, and help teams address performance, scalability, and reliability challenges.
Automate and improve delivery: Manage Linux infrastructure using Puppet and scripting, build CI/CD pipelines with GitLab, and work with Kubernetes, Argo CD / GitOps, and Terraform.
Ensure reliability at scale: Define service objectives (SLIs/SLOs), improve production readiness, and identify potential issues before they affect customers.
Strengthen observability: Improve monitoring, alerting, and troubleshooting using tools such as Icinga and the Elastic Stack.
Collaborate and share expertise: Work closely with developers and other engineering teams, share best practices, and contribute to technical discussions and decisions.
Support production operations: Participate in the on-call rotation, investigate incidents, and drive long-term improvements.
Your Profile
5–10 years of experience in Linux administration, infrastructure engineering, SRE, or a similar technical role.
Strong Linux expertise and a solid understanding of infrastructure architecture, troubleshooting, and production operations.
Experience taking technical ownership of infrastructure or platforms, beyond day-to-day administration.
Hands-on experience with automation and infrastructure tools, ideally Puppet, Ansible, scripting, or Terraform.
Familiarity with Kubernetes, CI/CD, GitOps, virtualization, or private cloud environments.
Understanding of monitoring, observability, backup, and service reliability principles.
A proactive, solution-oriented mindset, with the ability to challenge existing approaches and suggest practical improvements.
Good communication skills in French and English.
Nice to have: Experience with GitLab CI/CD, Argo CD, Icinga, Elastic Stack, Jira/Confluence, or AI-assisted engineering tools.
You don't need to know every tool in our stack from day one. We'll provide training on our internal systems and processes.
Your Benefits
Executive status
Fixed-hours arrangement
5 weeks of statutory paid vacation + RTT
€10 meal vouchers, with €5.92 covered by Hornetsecurity
100% coverage of public transportation costs
Health and life insurance coverage (Axa)
Subsidized sports and wellness programs
Access to an inter-company daycare
International exchange program
Ready to make an impact? Join a close-knit, international team where you'll have the freedom to take ownership, tackle meaningful technical challenges, and help build the next generation of our cybersecurity infrastructure.
