POSITION SUMMARY:

We are seeking a Sr. Security Engineer with a focus on cloud and application security to join our team as a hands-on individual contributor. This role is responsible for designing, implementing, and operating security controls that protect our e-commerce platforms and other enterprise technology environments.

The ideal candidate can take high-level security requirements and translate them into practical, scalable solutions in partnership with infrastructure, engineering, and product management teams. This individual will play a key role in strengthening our security posture across cloud platforms, application development pipelines, and customer-facing systems.

Success in this role requires strong technical execution, cross-functional collaboration, and the ability to operate as a generalist across multiple security domains. A proactive mindset, strong organizational skills, clear communication, and an appetite for continuous learning are essential.

RESPONSIBILITIES:

• Operate and enhance security solutions protecting customer-facing omnichannel commerce platforms, including web application firewalls (WAF), bot mitigation, and API security controls
• Drive improvements in cloud security posture across Azure and AWS environments using CSPM/CNAPP tooling, and implement scalable governance and security controls
• Build, integrate, and mature application security capabilities, including SAST, DAST, and SCA, embedding them into CI/CD pipelines and developer workflows ("shift-left" security)
• Partner with engineering, infrastructure, and product teams to implement secure solutions and ensure alignment with enterprise security standards
• Act as a security subject matter expert within enterprise initiatives, providing guidance and oversight for control implementation and risk reduction
• Drive the implementation and ongoing enhancement of security-owned tools and capabilities to reduce risk and improve analyst visibility
• Serve as an escalation point for internal security operations, supporting detection tuning, incident response, and threat analysis
• Develop and maintain automation (scripts, workflows, integrations) to improve the efficiency and consistency of security control deployment and enforcement
• Continuously evaluate emerging threats, technologies, and industry practices to enhance security capabilities and address evolving risks

ESSENTIAL QUALIFICATIONS:

• Strong understanding of network and application security technologies, including WAF, CDN, API security, and bot mitigation
• Experience securing cloud environments (primarily Azure and AWS), with the ability to implement controls programmatically and at scale
• Familiarity with cloud security tooling such as CSPM/CNAPP platforms and cloud-native security controls
• Understanding of modern software development practices, including CI/CD pipelines, containerization, and microservices architectures
• Experience integrating security tools (SAST, DAST, SCA) into development workflows and supporting "shift-left" security initiatives
• Proficiency in scripting or automation (e.g., PowerShell, Python, or similar) to support security engineering and operations
• Strong communication and organizational skills, with the ability to work effectively across technical and non-technical teams
• Ability to operate independently with minimal oversight while managing multiple priorities

PREFERRED QUALIFICATIONS:

• Experience with technologies such as Cloudflare, CrowdStrike (EDR/Cloud Security), BlackDuck/Snyk/GitHub Security, GitHub Enterprise, and SIEM platforms
• Understanding of identity and access management practices and implementation of IAM controls
• Familiarity with vulnerability management programs and tooling
• Exposure to operating within or managing multi-cloud environments
• Experience securing or evaluating AI/ML-based solutions in an enterprise environment
