Requirements
What we're looking for
- Proven experience in dedicated security engineering roles, ideally in cloud-first environments, built on a strong foundation in infrastructure, network, software or DevOps engineering.
- Hands-on experience securing cloud infrastructure and services in Microsoft Azure using native Azure security tooling, with working knowledge of vulnerability management, patching and endpoint protection.
- Experience with identity and access management in Microsoft Entra ID, including designing and managing Conditional Access policies, Privileged Identity Management (PIM) and role-based access control to enforce least privilege and strong authentication.
- Strong understanding of cloud network security, including segmentation, firewalls, WAFs and zero-trust network access (ZTNA), and of infrastructure hardening (e.g. CIS Benchmarks).
- Practical experience embedding security into development lifecycles and CI/CD pipelines, including design and code reviews and automated pipeline security scanning.
- Proficiency in scripting and automation (PowerShell, Python) and Infrastructure-as-Code (Bicep, Terraform).
- Knowledge of securing cloud-native, microservice and containerised systems, including container orchestration platforms.
- Solid understanding of security principles, common attack techniques and frameworks (e.g. OWASP Top 10, MITRE ATT&CK) and the threat landscape.
- Strong delivery focus, able to prioritise effectively and deliver outcomes in a fast-paced environment with shifting demands.
- Clear communicator, able to explain security risk to both technical and non-technical stakeholders and influence engineering teams.
Nice to have
- Microsoft security certifications, such as SC-500, SC-300 or SC-200.
- Industry-recognised cloud security certifications, such as GIAC GCSA or GPCS, or ISC2 CCSP.
- Hands-on experience deploying and operating zero-trust network access (ZTNA) solutions.
- Experience with SIEM platforms (Microsoft Sentinel preferred), including tuning detections, triaging alerts and responding to threats using established runbooks and procedures.
- Experience producing security documentation and supporting assurance activities in regulated environments.
- Application security experience, including threat modelling and application security testing (SAST/DAST).

Eligibility: You must have the right to work in the United Kingdom. Please note that we do not provide visa sponsorship.
The role
Position Overview: Atreides are seeking a motivated and proactive Cloud Security Engineer to join our dynamic and growing security team. Reporting to the Lead Security Architect, you will build, secure and operate zero-trust cloud environments, with a strong focus on Microsoft Azure and DevSecOps practices. This is a broad, hands-on engineering role suited to a platform security engineer or DevSecOps professional who enjoys working across the stack, from identity, Infrastructure-as-Code and CI/CD pipelines to detection, response and vulnerability management.
What you'll do
- Implement and support security controls across Azure, Microsoft Entra ID and the wider Microsoft stack, including Microsoft Defender for Cloud, Microsoft Defender XDR and Azure Policy.
- Apply zero-trust principles and harden infrastructure and applications against recognised standards (e.g. CIS Benchmarks), enforcing them through policy-as-code.
- Secure containerised workloads throughout their lifecycle, from image hardening and runtime configuration to isolation between services.
- Build and run security gates in DevOps pipelines that scan Infrastructure-as-Code (Bicep/Terraform), dependencies, secrets and container images, and produce auditable evidence.
- Develop security automation to improve efficiency, including policy enforcement, remediation and reporting, using scripting (PowerShell, Python) and Infrastructure-as-Code.
- Review designs and code early, challenge weaknesses, advise on fixes and feed security findings into change approval without slowing delivery.
- Triage vulnerability and misconfiguration findings, prioritise them by exposure and support owning teams through patching and remediation.
- Tune Microsoft Sentinel detections, investigate alerts and support incident response, following and improving playbooks and preserving evidence in line with defined procedures.
- Write and maintain security documentation, including control designs, hardening guides, SyOPs and runbooks, and provide evidence to support assurance activities.
Desired Qualifications and Experience
Team Principles: At Atreides, we believe that teams work best when they:
- Remain curious and passionate in all aspects of our work
- Promote clear, direct, and transparent communication
- Embrace the 'measure twice, cut once' philosophy
- Value and encourage diverse ideas and technologies
- Lead with empathy in all interactions
