We are a culture that is unabashedly driven by purpose — making a difference to patients and team members while growing at an accelerated rate.

This role is for a security professional who actively uses AI to outpace threats — automating detection, accelerating incident response, and embedding intelligent security controls throughout the development lifecycle rather than relying on manual, reactive approaches.

Role Accountabilities and Responsibilities:

AI-Augmented Threat Detection & Incident Response

- Leverage AI-powered security tooling to continuously monitor for threats, anomalies, and policy violations across cloud and application environments — replacing manual log review with intelligent, automated detection.

- Respond to and, where appropriate, resolve or escalate security incidents; use AI-assisted analysis to accelerate root cause investigation and postmortem documentation.

- Investigate and resolve security violations by providing postmortem analysis that illuminates causes, solutions, and AI-informed preventative measures.

- Use AI tools to model attack scenarios, identify exposure patterns, and prioritize remediation efforts based on risk — rather than relying solely on manual vulnerability triage.

AI-Driven Security Automation & "Security as Code"

- Assess, design, implement, automate, and document security solutions for public and private cloud environments, SaaS applications, and AWS-based platforms — with a bias toward AI-assisted automation over manual configuration.

- Implement "security as code" using cloud services and CI/CD components; use AI code generation tools to accelerate the development of custom security scripts and controls.

- Develop baseline cloud, container, and application security standards and integrate them into CI/CD pipelines — leveraging AI to identify gaps and validate coverage continuously.

- Customize cloud compliance tools to meet operational, audit, and risk-based needs; use AI-enhanced compliance monitoring to surface drift and exceptions in real time.

Cloud & Application Security

- Work with diverse technical and business stakeholders on security best practices in Infrastructure as Code, cloud design patterns, and CI/CD with built-in application security controls.

- Implement security architecture, methods, and controls required to meet security, compliance, and audit requirements across AWS and multi-cloud environments.

- Apply knowledge of network-based, system-level, and application-layer attacks and mitigation methods to design resilient, layered security architectures.

- Maintain strong knowledge of IDS/IPS, IAM, Certificate Management, identity federation, authentication, and authorization standards (SAML, OIDC, OAuth).

Documentation & Compliance

- Develop and maintain documentation for security systems, procedures, and controls — using AI-assisted drafting to improve quality and reduce documentation burden.

- Drive compliance through strict adherence to published information security policies and procedures; drive efficiencies via tooling and automation to continuously improve security posture.

Qualifications and Requirements:

- 4+ years of experience as a Security Engineer or equivalent.

- Significant technical experience in cloud computing technologies and security automation (primarily AWS).

- Required: Demonstrated, hands-on experience using AI tools to automate security tasks, accel
