At Lucid, we value diverse perspectives and are dedicated to creating an environment and culture that is respectful and inclusive for everyone. Lucid is a hybrid workplace. We promote a healthy work-life balance by allowing employees to work remotely, from one of our offices, or a combination of the two depending on the needs of the role and team.
As a Senior Application Security Engineer at Lucid, you will be a trusted security partner embedded in the heart of our development lifecycle. You'll work closely with engineering, product, and corporate teams to build security in from the start.

Lucid's customers trust us with their data, and that trust is foundational to our mission. A successful Senior Application Security Engineer combines deep technical knowledge with strong relationship-building skills, enabling product teams to move fast without taking on undue risk.

Responsibilities:

• Conduct thorough security architecture and design reviews for new and evolving product features, surfacing risk early and recommending practical mitigations.
• Drive a risk-based approach to application security, helping teams understand and prioritize vulnerabilities by business impact.
• Serve as a subject matter expert on application security topics for product, engineering, legal, and leadership stakeholders.
• Mentor engineers across the organization on secure development practices, fostering a culture where security is everyone's responsibility.
• Build and maintain strong, collaborative partnerships with product and engineering teams, serving as their primary security resource and advocate throughout the software development lifecycle.
• Mature Lucid's Secure Software Development Lifecycle (SSDLC), including secure coding standards, security requirements, and developer security education.
• Ensure AI tools and processes are implemented within acceptable risk limits.
• Lead product design reviews to ensure security considerations are inherent in feature design.
• Develop and maintain scalable security tooling and automation to integrate security controls into CI/CD pipelines with a focus on reducing risk over implementing tools.
• Lead and train engineers in Lucid’s security champions program.

Requirements:

• 5+ combined years of experience in software engineering, application security, product security, or a closely related field within a SaaS environment.
• Proven track record of building trusted, effective relationships with product and engineering teams.
• Experience securing web applications built on modern frameworks and cloud-native architectures (particularly AWS).
• White-box penetration testing experience.
• Strong understanding of SSDLC principles and experience implementing or maturing secure development programs.
• Ability to conduct meaningful security architecture and design reviews, with a focus on identifying risk early in the development process.
• Solid understanding of common application vulnerabilities and attack techniques (OWASP Top 10, API security, authentication/authorization flaws, etc.).
• Experience integrating security tooling into modern CI/CD pipelines.
• Risk-focused mindset: able to articulate security risk in business terms and help teams make informed, pragmatic decisions while avoiding security theater.
• Familiarity with AI security risks and emerging attack surfaces, including securing agentic systems, MCP, and LLM-powered workflows against new and evolving threats.
• Strong written and verbal communication skills; equally comfortable in a design review with engineers and a risk conversation with leadership.

Preferred Qualifications:

• Development experience in modern tech stacks.
• Practical knowledge of relevant security frameworks and compliance standards (e.g., OWASP ASVS, NIST 800-53, SOC 2, GDPR).
• Relevant certifications such as OSCP, BSCP, GWEB, PNPT, or similar hands-on security-focused certifications.
• Experience with bug bounty program management.
• Bachelor's degree in Computer Science, Information Security, or a related field.
