DevOps Engineer | Cybersecurity

We’re looking for a DevOps Engineer to own infrastructure, CI/CD and internal tooling for a cybersecurity company in Barcelona

• Location: Barcelona, Poblenou (100% on-site, by design)
• Salary: Competitive salary based on your experience and skills
• Benefits: Private health insurance, food allowance and wellness benefit, flexible office hours

About the company

A fast-growing, research-driven cybersecurity company based in Barcelona, developing advanced technology for the public sector (B2G).

• Mission-led: the product is built to make the world safer, and that purpose shapes how the team works
• Deep tech: original research and engineering applied to some of the most complex challenges in security
• Ownership culture: engineers take projects from concept to production, and their ideas carry weight

About the role

A broad, hands-on position spanning infrastructure, systems administration and developer tooling. You identify the problem, choose the practical solution and own it through to operations.

Day-to-day

• Internal tooling: build, deploy and maintain the services and tools that improve developer workflows
• Infrastructure and pipelines: enhance existing systems and GitLab CI/CD pipelines, troubleshoot issues and drive them to resolution
• Automation: script recurring tasks and configuration with Python or Bash and Ansible, contributing code where needed
• Containerized environments: operate and evolve Docker and Kubernetes setups
• Cross-team collaboration: work with developers, QA and operations to diagnose problems and accelerate delivery
• Continuous improvement: evaluate new technologies and AI-assisted tools that raise productivity
• End-to-end ownership: from initial fix to operational follow-through

What you’ll need

• Hands-on experience in DevOps, systems administration, platform engineering or developer tooling
• Solid Linux, networking and command-line fundamentals
• Practical experience with GitLab CI/CD, Docker and Kubernetes
• Scripting skills in Python or Bash, working knowledge of Ansible, and comfort reading or modifying code
• A pragmatic approach: you improve what already exists rather than defaulting to rewrites
• Strong communication, a service-oriented mindset and fluent English
• Nice to have: experience with AI-assisted development tools (Cursor, OpenCode) and Go

Who should apply?

A DevOps or systems engineer who enjoys owning solutions end to end, takes pride in making other engineers more effective, and is comfortable working on-site every day in Poblenou.
