Quantum Circuits Inc.

New Haven, US · Full-time · $140,000 – $180,000

About this role

At Quantum Circuits Inc., we are building the world’s first truly algorithmic quantum computers to achieve transformational computing capabilities. Our full-stack quantum computing platform uses superconducting devices along with a modular, robust, and scalable architecture based on a decade of technology research at Yale University's quantum labs.

We are seeking a highly skilled and self-motivated Senior Security Engineer to join our dynamic team. The role focuses on evaluating and mitigating security vulnerabilities across on-premises and AWS environments while being hands-on in assessing, designing, implementing, and maintaining a robust security posture.

This position ensures QCI’s infrastructure is secure, resilient, and capable of supporting our cutting-edge quantum computing platform. The engineer will secure in-house applications hosted on AWS and collaborate with network engineers on device configurations.

Working at the forefront of quantum technology, the role involves regular audits of Windows environments and Active Directory along with coordination of penetration testing to identify and address vulnerabilities proactively.

Requirements

5+ years of experience in security engineering, with a focus on both cloud (AWS) and on-premises environments.
Deep understanding of security concepts, including network security, encryption, identity and access management, and compliance standards (e.g., ISO, NIST, PCI-DSS).
Familiarity with NIST standards for secure data handling and destruction (e.g., NIST SP 800-88).
Experience with security tools for vulnerability scanning, incident detection, and monitoring (e.g., Black Duck, Nessus, Splunk, AWS Security Hub).
Hands-on experience managing and securing network devices such as firewalls, routers, and switches (e.g., SonicWall, Cisco, Juniper).
Strong scripting skills (Python, Bash, PowerShell) for automation of security tasks.
Knowledge of Windows environments (Active Directory, GPOs) and secure data handling processes.

Responsibilities

Assess and mitigate security risks across QCI’s on-premises and AWS environments, including securing in-house applications hosted on AWS.
Develop, implement, and maintain security policies, procedures, and best practices to safeguard systems, data, and QCI’s quantum computing platform.
Evaluate and enhance network security by auditing network devices and security appliances, identifying vulnerabilities, and recommending configurations.
Monitor and respond to security threats and incidents by developing and executing a comprehensive incident response plan.
Perform regular security audits, risk assessments, and vulnerability scans, including reviews of Windows environments, Active Directory, and GPO configurations.
Lead and coordinate penetration testing initiatives, conducting internal assessments and working with third-party security firms.
Automate security tasks such as monitoring, alerting, and compliance checks using scripting languages.
Raise security awareness by establishing a training program, including phishing campaigns and regular employee education.
