​This is a Full-Time role (typically remote or hybrid depending on the specific branch) for an experienced engineer with a minimum of 4+ years in the field. Plan A Technologies is a software consultancy that builds high-scale systems, and this role focuses on the Operational Security (SecOps) side of their cloud infrastructure. You will be responsible for the “day-to-day” health of their AWS security stack, ensuring that defenses are not only implemented but actively tuned to provide high-fidelity alerts.

• ​Experience Required: 4+ years in Cybersecurity Engineering or SecOps.
• ​Core Environment: Amazon Web Services (AWS).
• ​Key Tech: IDS/IPS, Firewalls, Endpoint Security (EDR), and SIEM/SOAR.
• ​Primary Focus: Implementation, Alert Monitoring, and Visibility.

​Key Responsibilities: Defense and Visibility

​This role is centered on maintaining the “Security Tech Stack” and ensuring the engineering teams have a secure environment to build in.

​Security Systems & AWS Infrastructure

​You will implement and maintain cloud network security systems, specifically within AWS. This involves configuring VPCs, IAM policies, and Security Groups in alignment with “least privilege” and “segmentation” principles. You are responsible for the lifecycle of security tools, including routine patching, tuning, and optimization of firewalls and IDS/IPS to ensure they are actually blocking modern threats.

​Monitoring and Detection Engineering

​A major portion of your day is spent in the logs. You will monitor security alerts and detection systems, investigating anomalies as they arise. You won’t just watch the alerts; you will tune the rules to improve fidelity. By reducing false positives, you ensure that the security team focuses only on meaningful signals. You will also help maintain the centralized logging infrastructure to ensure 100% visibility across all endpoints.

​Incident Support and Playbooks

​When an incident is escalated, you support the triage and containment phases. You will work within defined SLAs to report on findings and, more importantly, assist in refining the operational runbooks and playbooks. This ensures that the response to a specific threat (like a credential leak or malware infection) is repeatable and efficient.

​Required Qualifications and Skills

​Plan A Technologies is looking for a practitioner who understands “Defense-in-Depth” in a cloud-native context.

• ​Education: BS in Computer Science, Software Engineering, or equivalent practical experience.
• ​Cloud Expertise: Strong experience with AWS (Networking, IAM, VPC, CloudWatch/CloudTrail).
• ​Tool Proficiency: Hands-on experience with SIEM/SOAR platforms and cloud-native monitoring tools.
• ​Security Fundamentals: Deep understanding of core principles like Segmentation, Least Privilege, and Defense-in-Depth.
• ​Soft Skills: Strong documentation habits and the ability to collaborate with cross-functional IT and software engineering teams.
• ​Preferred: Certifications like Security+, CySA+, or AWS Security Specialty and basic scripting skills (Python/Bash).

​Summary of Role Impact

​Plan A Technologies handles complex software projects for a variety of clients. As their Cybersecurity Engineer, you are the guardian of the infrastructure that supports those projects. By maintaining a high-fidelity monitoring stack and a hardened AWS environment, you allow the software engineers to innovate with speed while ensuring that client data and company assets remain protected against unauthorized access and emerging vulnerabilities.
