If you're curious, bold, and excited to help shape a borderless financial future, we'd love to talk. As a Security Engineer with a focus on Application Security, you’ll be a key contributor in embedding security into Rain’s engineering lifecycle and supporting delivery of secure, trusted applications. You will lead application security assessments, including vulnerability scanning, code reviews, and threat modeling with engineering teams. You will partner closely with product and development squads to drive remediation and help teams understand and resolve security findings efficiently. You will integrate and scale automated security tooling across CI/CD pipelines (SAST, DAST, SCA, IaC) to shift security left. You will develop and maintain application security standards, patterns, and guardrails that reduce risk and support rapid delivery. You will drive threat modeling and risk assessments for new features, APIs, and services. You will collaborate with Cloud & Infrastructure Security to align security controls across layers and support cloud-native security requirements. You will support incident response for application-level security events and contribute to root-cause analysis and future mitigation strategies. You will help build internal training and awareness programs to elevate secure coding and developer security literacy. You will track and surface key security metrics, trends, and continuous improvement insights to leadership.
