About the Role

As a Senior Cloud Security Engineer, you will improve the security of AlphaSense’s cloud environments within the cloud security team. This hands-on, high-autonomy role allows you to own security projects end-to-end, from problem identification to control operation, driving them to measurable outcomes. You should have solid experience with containerized environments, infrastructure as code, and Kubernetes across a multi-cloud (AWS and GCP) estate. Ideal candidates have a strong cloud security background, with DevOps/infrastructure engineering experience and a keen interest in cloud security development also welcomed.

Responsibilities

  • Design, develop, and automate security controls for cloud infrastructure across AWS and GCP.
  • Maintain, integrate, and scale cloud security tooling, including cloud security posture management and vulnerability platforms.
  • Investigate and remediate security vulnerabilities in cloud infrastructure, driving them to closure.
  • Design and build access controls across cloud and Kubernetes environments, applying zero-trust principles.
  • Partner with incident response teams to build detections for cloud infrastructure and help mitigate security incidents.
  • Develop security standards and guardrails for other engineering teams, embedding them into CI/CD and GitOps workflows.
  • Work with compliance teams to ensure adherence to frameworks like ISO 27001, SOC 2, and GDPR, translating requirements into technical controls.
  • Conduct architecture reviews, threat modeling, and code reviews to identify security risks.
  • Lead security projects independently, including scoping, planning, and driving cross-functional work.

Requirements

  • 5+ years of experience in cloud security, or in security-focused infrastructure/DevOps engineering.
  • Hands-on experience securing containerized environments and Kubernetes.
  • Strong understanding of AWS and infrastructure-as-code solutions.
  • Proficiency in one or more programming or scripting languages (e.g., Python) for automation.
  • Experience working with cloud security posture management or similar security tooling.
  • A self-starter and problem solver who can own problems end-to-end, drive projects with minimal direction, and communicate clearly across teams.
  • Experience across multiple clouds (AWS and GCP).
  • Experience integrating security into CI/CD pipelines and DevOps/GitOps workflows.
  • Hands-on experience with threat modeling and security architecture reviews.
  • Hands-on experience working with compliance requirements and turning them into technical controls.
  • Contributions to security communities, open-source projects, or security research.
  • Relevant security certifications (e.g., CKS).
