Full Stack Security Engineer (Application & Product)

Role overview

Improve the security of customer-facing applications, APIs, and internal services by working directly with software teams throughout development. This hands-on product security role combines architecture review and testing with writing fixes, automating security checks, and helping engineers build secure practices into everyday work.

Responsibilities

- Lead threat modeling, architecture assessments, and code reviews for web applications, APIs, and microservices. - Work alongside engineers to implement fixes for vulnerabilities in Python, Go, JavaScript, TypeScript, or comparable codebases. - Add and tune static, dynamic, and dependency security checks in CI/CD pipelines so issues are found earlier. - Configure application defenses such as web application firewalls, bot protection, and API gateways. - Provide secure coding guidance, training, and procedures to development teams. - Coordinate with operations on security framework requirements and help triage vulnerability reports.

Requirements

- Five or more years in application or product security, or software engineering with a substantial security focus. - Strong programming and code review skills in a modern language such as Python, Go, JavaScript, or TypeScript. - Deep understanding of common web vulnerabilities, REST or GraphQL API security, and authentication protocols such as OAuth, OIDC, and JWT. - Hands-on use of web security testing tools such as Burp Suite or ZAP. - Experience building or maintaining automated security checks in development pipelines. - Ability to turn complex security findings into clear, actionable engineering work.

Nice to have

- Application security certifications, experience protecting Kubernetes or Docker workloads, or involvement in bug bounty and coordinated disclosure programs. - Familiarity with SOC 2, ISO 27001, or GDPR requirements.
