Job description

The Opportunity

Location: Lisbon, Portugal – Hybrid (3 days per week onsite)

We are looking for Cloud Security Engineers to join an engineering-led security team within a growing technology business.

This is a hands-on engineering position focused on securing cloud infrastructure, improving security architecture and developing practical solutions to complex cloud security challenges.

You'll work closely with cloud infrastructure, platform and software engineering teams to ensure security is embedded into the design, development and operation of cloud environments.

We're particularly interested in engineers who enjoy building, automating and improving security solutions, rather than simply managing security platforms or monitoring alerts.

What You'll Be Doing

• Design, implement and maintain security controls across cloud environments.


• Work closely with engineering teams to improve cloud security architecture.


• Identify and remediate cloud infrastructure vulnerabilities and misconfigurations.


• Develop automation and tooling to improve cloud security and operational efficiency.


• Implement security best practices across infrastructure, identity and access management.


• Secure cloud-native environments, workloads and containerised applications.


• Improve Infrastructure as Code security and integrate security into deployment pipelines.


• Support cloud security monitoring, vulnerability management and incident prevention.


• Evaluate emerging technologies and identify opportunities to strengthen cloud security.

What We're Looking For

• Experience in Cloud Security Engineering, DevSecOps, Platform Security or Cloud Infrastructure Engineering.


• Strong hands-on experience with at least one major cloud platform, ideally AWS or GCP.


• Ability to write code or scripts using languages such as Python, Go, Java or PowerShell.


• Experience with Infrastructure as Code, particularly Terraform.


• Understanding of Kubernetes, containers and cloud-native architectures.


• Knowledge of cloud security principles, including IAM, networking, encryption and workload security.


• Experience automating security controls and improving infrastructure security.


• A strong engineering mindset and the ability to work directly with technical teams.

Senior Engineer – Additional Experience

For the senior position, we're particularly interested in candidates who can demonstrate:

• Ownership of cloud security architecture and engineering initiatives.


• Experience designing and implementing security solutions at scale.


• Strong technical expertise across cloud infrastructure, automation and security controls.


• Ability to influence engineering standards and mentor other technical professionals.

The Environment

You’ll be joining a security function that values engineering capability and practical problem-solving. The team is focused on building secure, scalable cloud environments and developing solutions rather than relying solely on third-party tooling.

Three days per week onsite in central Lisbon.
