Senior Security Engineer

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. Our unique approach is based on a decade of technology research and breakthroughs at Yale University’s world‑renowned quantum labs. We are seeking a highly skilled and self‑motivated Senior Security Engineer to join our dynamic team. The ideal candidate has a strong background in evaluating and mitigating security vulnerabilities across on‑premises and AWS environments and will be hands‑on in assessing, designing, implementing, and maintaining a robust security posture for all systems. This ensures QCI’s infrastructure is secure, resilient, and capable of supporting our cutting‑edge quantum computing platform. Key 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 (e.g., SonicWall, Cisco, Juniper), identifying vulnerabilities, and recommending configurations. Collaborate with network engineers for implementation. Monitor and respond to security threats and incidents by developing and executing a comprehensive incident response plan to detect, communicate, contain, and remediate security breaches effectively. 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 to identify vulnerabilities and working with third‑party security firms for comprehensive evaluations. Automate security tasks such as monitoring, alerting, and compliance checks using scripting languages (e.g., Python, Bash). Raise security awareness by establishing a training program, including phishing campaigns and regular employee education to promote best practices. Collaborate with leadership to report on security status, vulnerabilities, and improvement plans, ensuring proactive risk management. Ensure compliance with third‑party vendor security policies by designing and implementing security measures for systems handling external data. Oversee secure data handling and retention processes, including encryption, retention, deletion, and forensic destruction in alignment with industry standards such as NIST guidelines. Regularly review access logs for potential security threats and unauthorized access, providing detailed reports as required by external audits or risk assessments. Minimum Qualifications: 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 securing Windows‑based systems. Excellent communication skills, with the ability to convey complex security concepts to both technical and non‑technical stakeholders. Self‑motivated and able to take ownership of projects, driving them to completion. Preferred Qualifications: 7+ years of experience in a security‑focused role. Security certifications such as CISSP, CEH, CISM, or AWS Certified Security Specialty. Experience in designing and implementing security for microservices, containers, and serverless architectures supporting complex platforms. Experience ensuring compliance with third‑party security policies and external regulatory requirements. Knowledge of secure integration practices for external APIs and third‑party platforms. Familiarity with modern logging and monitoring solutions (e.g., ELK Stack, Prometheus, Grafana). Penetration testing and ethical hacking experience (e.g., Metasploit, Kali Linux). Knowledge of compliance requirements and experience implementing secure solutions to meet regulatory standards. Location & Work Arrangements: This is a hybrid role based in New Haven, CT, with the flexibility to work from home but requiring regular onsite presence. Sponsorship is available for qualified candidates. #J-18808-Ljbffr ROLE
