Opportunity

As a Senior Cloud Security Engineer you will have experience in investigating advanced threats, detecting cloud‑native attacker techniques, and securing AWS environments, with a focus on technical controls, incident response, and detection engineering. You will work with other engineering teams to identify and mitigate risks across our cloud infrastructure, develop and enforce security measures within our cloud infrastructure, and deliver a safe and secure engineering environment. You will identify and detect threats to our business and drive our response to security incidents. The ideal candidate has a strong background in cloud computing, infrastructure as code, and a deep understanding of AWS services.

Responsibilities

Leverage cloud‑native security tools (e.g., IAM, GuardDuty, AWS WAF, Security Hub) along with EDR and SIEM to enhance security posture.

Develop strategies, frameworks, automations, and processes to advance the Detection and Response program.

Create protective and detective controls using open‑source and closed‑source intelligence sources to address gaps and detect potential intrusions.

Collaborate with product engineering teams to manage and resolve security incidents, ensuring effective containment and mitigation.

Automate security controls and compliance checks to maintain adherence to security standards.

Partner with infrastructure teams to expand automation and infrastructure as code practices for secure, scalable operations.

Qualifications

Experience in investigating advanced threats and detecting cloud‑native attacker techniques using a modern detection engineering approach, with deep expertise in attacker behavior, technical controls, and diverse technologies.

Experience securing AWS environments, developing detections, and responding to security incidents, including containment, investigation, and recovery.

Solid understanding and demonstrated expertise managing AWS security controls and ensuring the security of cloud service offerings (IAM, VPC, firewalls/ACL, IDS/IPS, WAF, Linux hosts, serverless, etc.).

Proficiency in a high‑level programming language (e.g., Python, Ruby) for automation of security tasks.

Experience implementing Infrastructure as Code (IaC) practices using tools such as Terraform, AWS CloudFormation, or similar.

Ability to thrive in a fast‑moving environment, with the autonomy to prioritise, explore, and determine your own solutions to problems.

Support and Development

You will report to the Cloud Security Engineering Manager. You will buddy with another Dublin‑based Cloud Security engineer who will help you onboard and get up to speed quickly. You will have a close group of InfoSec peers to collaborate with and learn from. We invest heavily in our engineers, supporting individual career development through training and coaching.
